Description

TREATMENT AGENT FOR MACRO STICKIES AND TREATMENT METHOD FOR MACRO STICKIESThe present invention relates to a treatment agent for macro stickies, a treatment method for macro stickies, and the like.Pulp-containing water in paper manufacturing contains pitch, which causes a pitch obstacle. In general, pitches refer to hydrophobic pressure adhesive substances that mainly include a resin component derived from pulp, a synthetic pressure adhesive substance in recycled used paper, and an organic substance derived from an added chemical agent that is used in a paper manufacturing step. Pitches are contained in the pulp-containing water that is used for a raw material for papermaking. In a case of being accumulated, it causes pitch troubles such as frequent defects (spots) due to agglomerated pitch lumps, cutting caused by pitches that have adhered to a paper making machine, a paper making tool, equipment in a paper manufacturing step, or the like, a decrease in product quality, a decrease in production efficiency, and deterioration of dewaterability.To cope with the pitch troubles, the following countermeasures have been executed: removal of pitch contaminants by equipment resin coating, a screen, or a cleaner; mechanical countermeasures such as pitch lump refinement using a kneader or a refiner, or countermeasures with chemical agents such as an externally added chemical agent such as a tool cleaning agent and an internally added chemical agent such as a fixing agent, a dispersant, a non-pressure adhesiveness imparting agent, or a degrading enzyme; and pitch trouble countermeasures such as countermeasures by regular machine cleaning and adjustment of operating conditions such as an amount of surplus white water or rejected substance slurry to be discharged outside the system.The following chemical agents have been proposed as internally added chemical agents for the pitch trouble countermeasures. For example, an internally added chemical agent for reducing pressure adhesiveness of pitches by using an inorganic chemical agent or a fine particle resin is known. For example, Patent Literature 1 proposes a pulp pitch absorbing agent for papermaking, which is obtained by mixing a natural talc powder with a small amount of non-swellable fluorine mica powder.In addition, there is known an internally added chemical agent for preventing pitch agglomeration by a dispersion action of a surfactant. For example, Patent Literature 2 proposes a pitch adhesion inhibitor for papermaking, which is characterized by containing a polymer containing, as a constitutional unit, maleic acid or maleamic acid, and isobutylene, diisobutylene, or styrene, and a nonionic surfactant at a ratio of 50:50 to 10:90 in terms of weight ratio.There are known the discharge of pitches from the system by an internally added chemical agent having a polymer fixing action, and the prevention of pitch aggregation by an internally added chemical agent having a dispersion action. For example, Patent Literature 3 proposes a pitch dispersant for a paper making system, which contains a water-soluble polyvinyl alcohol as an active ingredient, where the pitch dispersant consists of a constitutional unit represented by Formula (I) described in the literature and a constitutional unit represented by Formula (II) described in the literature, the constitutional unit represented by Formula (I) is about 70% to 80% by mole, and the constitutional unit represented by Formula (II) is about 30% to 20% by mole.In addition, there is known an internally added chemical agent for pitch degradation by an enzyme. For example, in Patent Literature 4 proposes a pitch trouble prevention method that is characterized by treating a raw material for paper manufacturing and / or white water with a hydrolytic enzyme for fatty acid glyceride, thereby removing pitches in the raw material for paper manufacturing and / or the white water, in a mechanical pulp manufacturing step and / or a paper manufacturing step using mechanical pulp.Japanese Examined Patent Application Publication No. S61-048975Japanese Examined Patent Application Publication No. S59-028676Japanese Examined Patent Application Publication No. H02-014479Japanese Examined Patent Application Publication No. H04-029794The inventors of the present invention recently studied a pitch obstacle in the paper manufacturing step. Pitches are broadly classified into fine pitches and macro stickies.Fine pitches are pitches of less than 150 μm and are characterized by the fact that they accumulate in the process water of the paper making step in association with the reuse of water and then cause troubles. In treatment of an internally added chemical agent for the fine pitches, a certain effect can be expected in a case where chemical agents having actions of fixation, dispersion, non-pressure adhesiveness, and degradation, respectively, are properly used for different purposes depending on the situation.On the other hand, macro stickies are said to be large-size pitches having a particle diameter of 150 μm or more (according to quantification using a method according to JISP8231:2005), and macro stickies observed in a paperboard are mainly derived from undisintegrated materials of organic pressure adhesive materials such as a pressure adhesive tape, a pressure adhesive label, and a pressure adhesive component, which are contaminants from the used paper as a raw material. As the reuse rate of used paper has increased in recent years, low-grade used paper that contains a lot of organic pressure adhesives such as pressure adhesive components or adhesive components of pressure adhesive tapes and the like have started to be reused as a raw material, and thus it is also becoming important to take countermeasures against macro stickies, which are easily formed from such pressure adhesive materials and has large particle size.However, regarding an internally added chemical agent that exhibits an effect of a fixing action or a dispersion action, which can be expected to be effective against the fine pitches, a pitch control effect by the internally added chemical agent is not sufficient with respect to macro stickies since macro stickies have a large particle size (for example, the chemical agents used in Comparative Examples 1-1 to 1-8 shown in [Examples] described later).Therefore, a main objective of the present invention is to provide a new technique for treatment of macro stickies.As a result of intensive studies on the characteristics of macro stickies, the inventors of the present inventions were able to newly find a chemical agent and conditions, which make it possible to favorably treat macro stickies. The present invention is as follows.The present invention can provide a treatment agent for macro stickies, which contains one or two or more selected from an oily and fatty compound having a melting point of 50°C or lower, a polyvinyl alcohol having a cationic group, and a cationic compound used for positive conversion.The present invention can provide a treatment method for macro stickies, which uses a treatment agent for macro stickies, for a macro stickies-containing object, in which the treatment agent contains one or two or more selected from an oily and fatty compound having a melting point of 50°C or lower, a polyvinyl alcohol having a cationic group, and a cationic compound used for positive conversion.According to the present invention, it is possible to provide a new technique for treatment of macro stickies.Fig. 1 is a schematic diagram showing one example of a paper manufacturing step (preparation step, paper making step, water recovery step) according to the present embodiment, and the step according to the present embodiment is not limited thereto.Fig. 2 shows one example of a graph that is used to determine an estimated molecular weight of a polymer in the present embodiment. The horizontal axis indicates the intrinsic viscosity (η), and the vertical axis indicates the average molecular weight (×104).Hereinafter, embodiments for executing the present invention will be described in detail. It is noted that the embodiment described below is one example of a representative embodiment of the present invention, and the scope of the present invention is not interpreted to be limited thereby. It is noted that an upper limit value and a lower limit value regarding a numerical value can be any combination as desired. In addition, unless otherwise specified, "to" for numerical values means "equal to or more than" and "equal to or less than".1. Technique for treatment of macro stickies according to present invention.A main objective of the present invention is to provide a new technique for treatment of macro stickies. As a result of intensive studies on the properties of macro stickies, the inventors of the present inventions were able to newly find a chemical agent and conditions, which make it possible to favorably treat macro stickies. The present technique is a technique that can make macro stickies non-pressure adhesive with a remarkably strong action, and this makes it possible to more favorably treat macro stickies contained in an object and makes it possible to reduce pitch troubles derived from macro stickies. Examples of the present technique include (a) using, as a chemical agent for treatment of macro stickies, one or two or more selected from a specific oily and fatty compound, a specific polyvinyl alcohol, and a specific cationic compound; and (b) objecting a macro stickies-containing object to positive conversion using a specific cationic compound. A (c) macro stickies-containing object in paper manufacturing is not particularly limited. Examples thereof include water containing macro stickies, and more suitable examples thereof include one or two or more selected from process water containing macro stickies (for example, pulp-containing water containing macro stickies (hereinafter, also referred to as a "slurry")) and the like. Even objects having a large amount (for example, content or adhesion amount) of macro stickies can be treated with the present technique. Examples of the water having a large amount of macro stickies include water that is reused in rejected substances by a screen or a cleaner, which has the ability to remove macro stickies, pulp-containing water that is used for a used paper raw material, and circulating pulp-containing water, and such objects can be treated intensively.Regarding the technique for treatment of macro stickies according to the present invention, the treatment agent for macro stickies according to the present invention, and the treatment method for macro stickies according to the present invention will be described in more detail below.The present invention can provide a technique for making macro stickies non-pressure adhesive with a remarkably strong action, thereby reducing pitch troubles derived from macro stickies.In a case where the present invention is used, defects derived from pitches are reduced. As a result, the paper loss rate and the coupling rate are reduced, and the productivity and the quality of the product (paper) are improved. In addition, in a case where the present invention is used, it is possible to reduce paper breakage due to the pitches that have adhered to a paper making machine or process equipment, which is provided for paper manufacturing. In addition, in a case where the present invention is used, it is possible to reduce the cleaning frequency and cleaning time for a paper making machine or equipment in paper manufacturing. In addition, in a case where the present invention is used, the deterioration of dewatering performance or the uneven moisture content in paper manufacturing due to the deterioration of tools is eliminated, which makes it possible to increase production volume, reduce the amount of steam, and improve product quality. In addition, in a case where the present invention is used, a rejected raw material can be reused, and it is possible to use an inexpensive raw material having a lot of contaminants.The present invention can provide a technique for reducing stains derived from macro stickies of a paper making machine, defects (spots) due to the stains, and paper breakage, which makes it possible to improve the efficiency of paper manufacturing work or man-hours and improve the quality of paper products. In addition, the present invention can provide a technique that targets a paper making machine for paperboard in which a pitch obstacle occurs easily, where the pitch obstacle is caused by macro stickies, which are undisintegrated pressure adhesive materials derived from tapes or labels contained in the used paper as a raw material. In addition, it is possible to provide a technique for preventing macro stickies from becoming coarse by reducing the pressure adhesiveness of macro stickies with a chemical agent treatment, where the coarsening is caused by the adhesion of macro stickies to a paper making machine or by adhesion of macro stickies to each other.2.

In the same manner, a blank test is carried out using pure water (blank).Colloidal equivalent value of cation (meq / g) = [measurement value of sample (ml) - titration amount in blank test (ml)] / 2The cationic polyvinyl alcohol that is used in the present invention can be obtained according to a publicly known production method, and for example, it can be obtained by saponifying a copolymer of an unsaturated monomer having a cationic group and a vinyl ester-based monomer. The copolymer of an unsaturated monomer having a cationic group and a vinyl ester-based monomer can be obtained by a publicly known polymerization method or the like in the related art.

Cationic compound for positive conversionThe cationic compound used for positive conversion (hereinafter, also referred to as a "cationic compound for positive conversion"), which is used in the present invention, is not particularly limited. In addition, the cationic compound for positive conversion may be a chemical agent or cationic chemical agent that contains a cationic compound and is used for subjecting a macro stickies-containing object to positive conversion, or it may be an agent that contains a cationic compound and treats macro stickies by being used at an amount equal to or larger than an amount which allows a macro stickies-containing object to undergo positive conversion.The cationic compound for positive conversion is not particularly limited; however, examples thereof include a cationic surfactant and a cationic polymer compound.The cationic compound for positive conversion is a cationic compound for subjecting a state of an object containing macro stickies to positive conversion by increasing the adding amount thereof, and it is suitably used so that the amount thereof is equal to or larger than an amount which allows the object to undergo positive conversion.The term "positive conversion" in the present specification is as follows. Usually, a pulp slurry, which is a raw material for paper manufacturing, is anionic, and a case where a cationic compound is added to the pulp slurry to make it in a cation surplus state is referred to as positive conversion. In a case where "positive conversion" occurs or "positive conversion" is caused to occur, the zeta potential or streaming potential changes from minus (-) to plus (+). In the present invention, it is suitable to make a decision that “positive conversion” or “an amount equal to or larger than an amount which allows positive conversion” is reached in a case where a change in zeta potential has changed from minus (-) to plus (+), by measuring a zeta potential of a treatment object (for example, an object such as a raw material slurry, pulp-containing water, rejected water) and observing a change in zeta potential.The raw material slurry contains anionic substances such as pulp fibers or anionic trash, and these substances are more reactive with a cationic compound than macro stickies. Therefore, in a case where a cationic compound is added to the raw material slurry, substances other than the macro stickies react with the cationic compound in advance. In a case where all substances other than the macro stickies react with the cationic compound, the cationic compound is to be in a surplus state. In a case where this surplus state occurs, the object containing macro stickies (for example, the raw material slurry or pulp-containing water) undergoes "positive conversion''. In a case where an amount of a cationic compound, which is equal to or larger than an amount which allows an object to undergo positive conversion, is added to the object containing macro stickies, the surplus cationic compound that is in a surplus state reacts with the macro stickies. This makes it possible to reduce the pressure adhesiveness derived from macro stickies or derived from undisintegrated materials of pressure adhesive materials that cause the formation of the macro stickies.That is, the cationic compound used for positive conversion, which is used in the present invention, can reduce the pressure adhesiveness derived from macro stickies. In a case where the cationic compound for positive conversion is used (for example, added, blended, or mixed) such that an amount equal to or larger than an amount which allows an object containing macro stickies in the paper manufacturing step to undergo positive conversion, it can more efficiently reduce the pressure adhesiveness derived from macro stickies.In addition, it is suitable that the above-described cationic compound for positive conversion is used such that an amount larger than an amount which allows a macro stickies-containing object to undergo positive conversion is used (for example, added), which makes it possible to favorably treat macro stickies contained in the object in the paper manufacturing step and reduces the pressure adhesiveness derived from macro stickies or derived from undisintegrated materials of pressure adhesive materials that cause the formation of the macro stickies. As a result, it is possible to prevent macro stickies in the process water from adhering to other places and prevent macro stickies from becoming coarser in the process water. In this case, it is more suitable to use, among the cationic compounds for positive conversion, a cationic surfactant or a cationic polymer compound.The cationic surfactant that is used in the present invention is not particularly limited. However, examples thereof include quaternary tetraalkylammonium salts such as dodecyltrimethylammonium chloride and didodecyldimethylammonium chloride; quaternary benzylammonium salts such as benzyldimethyldodecylammonium chloride, benzyldimethyltetradecylammonium chloride, and benzyldimethyloctadecylammonium chloride; and pyridinium salts such as N-dodecylpyridinium chloride. One or two or more selected from these substances can be used. Among these, it is possible to suitably use a benzyldimethylalkylammonium chloride, which is generally referred to as a benzalkonium chloride. The alkyl group of the benzyldimethylalkylammonium salt preferably has 10 to 20 carbon atoms, and more preferably has 12 to 16 carbon atoms.The cationic polymer compound that is used in the present invention is not particularly limited. However, examples thereof include polymer compounds respectively having a diallyldialkylammonium salt structure represented by General Formula (3) or General Formula (4), a vinylpyridinium salt structure represented by General Formula (5), a (meth)acryloyloxyethyltrialkylammonium salt structure represented by General Formula (6), an ammonium salt structure of a cyclic amidine, represented by General Formula (7), a structure of an addition polymer of a dialkylamine and epihalohydrin, represented by General Formula (8), a structure of an addition polymer of an N,N,N',N'-tetraalkylalkylene diamine and an alkylene dihalide, represented by General Formula (9), and the like, and one or two or more selected from these substances can be used.In the present invention, any of homopolymers and copolymers, which have these structures, can be used as the cationic polymer compound. Further, it is also possible to use a cationic polymer compound obtained by copolymerizing a nonionic monomer such as (meth)acrylamide, (meth)acrylonitrile, methyl (meth)acrylate, ethyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, styrene, vinyl acetate, or N-vinylpyrrolidone.Among these cationic polymer compounds, poly(diallyldimethylammonium chloride) having a structural unit represented by General Formula (4) can be particularly suitably used.Specific examples of the polymer compound having the (meth)acryloyloxyethyltrialkylammonium salt structure are not particularly limited; however, examples thereof include a copolymer product of acrylamide and acryloyloxyethyltrimethylammonium chloride, and a polymer product of methacryloyloxyethyltrimethylammonium chloride.Specific examples of the polymer compound having the ammonium salt structure of a cyclic amidine are not particularly limited; however, examples thereof include a copolymer product of acrylamide, acrylonitrile, N-vinylacrylamidine hydrochloride, N-vinylacrylamide, vinylamine hydrochloride, and N-vinylformamide.Specific examples of the polymer compound having the structure of an addition polymer of a dialkylamine and epihalohydrin are not particularly limited; however, examples thereof include an alkylamine-epichlorohydrin condensate.The number average molecular weight (Mn) of the cationic polymer compound (more suitably, the polydiallyldimethylammonium salt) is not particularly limited. However, the suitable lower limit value thereof is preferably 1,000 or more, more preferably 5,000 or more, and still more preferably 10,000 or more. In addition, the suitable upper limit value thereof is preferably 1,000,000 or less, more preferably 800,000 or less, still more preferably 500,000 or less, and even more preferably 400,000 or less, and the suitable numerical value range thereof is preferably 10,000 to 500,000.<Calculation method for estimated average molecular weight of water-soluble cationic polymer compound>In the present specification, the estimated average molecular weight of the water-soluble cationic polymer compound can be determined from the relationship between the intrinsic viscosity and the average molecular weight. More specifically, the relationship between intrinsic viscosity and average molecular weight is determined from various polymers which have a known intrinsic viscosity and a known average molecular weight. An intrinsic viscosity of a sample polymer is measured. The intrinsic viscosity of the sample polymer is applied to the relationship between the intrinsic viscosity and the average molecular weight, the average molecular weight of the sample polymer is determined from the relationship, and the determined average molecular weight is taken as the estimated average molecular weight of the sample polymer. It is noted that Fig. 2 shows the data for the DAM (CH3Cl) (2-methacryloyloxyethyltrimethylammonium chloride) polymer product. In addition, in a case of cationic PVA, the following expression may be applied: degree of polymerization × 207.5 = average molecular weight.<Method for determining estimated average molecular weights of various polymers (water-soluble cationic polymer compounds)>The intrinsic viscosity [η] of the polymer (water-soluble cationic polymer compound) which has been determined according to the method for determining an intrinsic viscosity based on the Huggins equation, in <Measuring method for intrinsic viscosity> described below, is applied to "the relationship between [η] and the average molecular weight (×104) which are determined from the molecular weight measurement results by the light scattering method (for example, see Figure 2)", the average molecular weight of the polymer is determined from the correlation thereof, and this can be used as the estimated molecular weight of the polymer (water-soluble cationic polymer compound) based on the relationship between the intrinsic viscosity and the average molecular weight.<Measuring method for intrinsic viscosity>The intrinsic viscosity can be determined according to the following procedures (I) to (V).(I) Five Cannon-Fenske Viscometers (No. 75, manufactured by Kusano Science Corp.) are soaked in a neutral detergent for glassware for more than one day and then washed sufficiently with water, followed by being dried.(II) According to the same procedure as in the measurement operation for the colloidal equivalent value described above, a W / O emulsion type polymer is diluted with water to prepare an aqueous solution having a polymer concentration of 0.2% by mass.(III) 50 mL of an aqueous solution of 2 mol / L sodium nitrate was added to 50 mL of the aqueous solution having a polymer concentration of 0.2% by mass which had been prepared in (II) described above, and stirring was carried out with a magnetic stirrer at 500 rpm for 20 minutes to obtain an aqueous solution of 1 mol / L sodium nitrate, the aqueous solution having a polymer concentration of 0.1% by mass. This is diluted with an aqueous solution of 1 mol / L sodium nitrate to prepare polymer solution samples having five steps of polymer concentrations of 0.02%, 0.04%, 0.06%, 0.08%, and 0.1% by mass. It is noted that an aqueous solution of 1 mol / L sodium nitrate, to which no polymer is added, is used as a blank liquid.(IV) Five viscometers prepared in (I) were vertically attached in a constant-temperature water bath which had been adjusted to a temperature of 30°C (within ±0.02°C). 10 mL of the blank liquid is placed in each viscometer using a whole pipette and then allowed to stand for about 30 minutes to make the temperature constant. Thereafter, the liquid is sucked up using a dropper and allowed to fall naturally, and then the time taken to pass the marked line is measured up to the 1 / 100 second unit using a stopwatch. This measurement is repeated five times for each viscometer, and the average value is taken as a blank value (t0).(V) 10 mL of each of the polymer solution samples having five steps of polymer concentrations, which have been prepared in (III), are placed in each of the five viscometers that have been used to measure the blank liquid and allowed to stand for about 30 minutes to make the temperature constant. Thereafter, the same operation as in the measurement of the blank liquid is repeated three times, and the average value of the passage times for each concentration is taken as a measurement value (t).From the blank value t0, the measurement value t, and the concentration [mass / volume%] (= C [g / dL]) of the polymer solution sample, the relative viscosity ηrel, the specific viscosity ηSP, and reduced viscosity ηSP / C [dL / g] are determined according to the relational expressions shown in Expressions (5) and (6) below.ηrel = t / t0 (5)ηSP = (t - t0) / t0 = ηrel - 1 (6)From these values, the intrinsic viscosity [η] of each polymer is determined according to the method for determining an intrinsic viscosity based on the Huggins equation described above.Regarding the cationic compound for positive conversion, which is used in the present invention, one kind thereof may be used alone, or two or more kinds thereof may be used in combination. In addition, as the cationic compound for positive conversion, a synthetic product may be used, or a commercially available product may be used.2-4. <Optional component>In the present invention, in addition to the above-described liquid oily and fatty compound, cationic PVA, or cationic compound for positive conversion, optional components may be appropriately added to an object such as a water system at the same time or separately or may be included in the chemical agent within a range where the effect of the present invention is not impaired. The optional component is not particularly limited. However, examples thereof include salts, a thickener, a dispersant, a surfactant, a pH adjusting agent, an anti-foaming agent, and a preservatives, and one or two or more selected from these substances can be used.2-5.

Examples of the treatment action include an action of preventing adhesion of macro stickies, an action of preventing coarsening of macro stickies, and an action of reducing stains. One or two or more selected from these actions can be used; however, the actions are not limited to these. Since the compound that is used in the present invention has the above-described action of treating macro stickies, the compound that is used in the present invention can be contained in a chemical agent such as a treatment agent for pitch stains, a treatment agent for macro stickies, or a chemical agent for a paper manufacturing step, or can be used for these chemical agents.

Treatment method for macro stickies according to present inventionIn the description of the treatment method for macro stickies in the present embodiment, the description of each configuration of the object, the liquid oily and fatty compound, the cationic polyvinyl alcohol, the cationic compound for positive conversion, and the like, and the description of each treatment method, which overlap with the above-described "1." and "2.", the following "4.", and the like, will be omitted as appropriate; however, the descriptions in "1.", "2.", "4.", and the like are also applicable to the present embodiment and can be adopted as appropriate. In addition, in the description of the example of the treatment method for macro stickies in the present embodiment, the description described later can also be applied to the present embodiment and can be adopted as appropriate.The present embodiment can provide a treatment method for macro stickies, which uses a treatment agent for macro stickies, for a macro stickies-containing object, in which the treatment agent contains one or two or more selected from an oily and fatty compound having a melting point of 50°C or lower, a polyvinyl alcohol having a cationic group, and a cationic compound used for positive conversion, or contains the specific compound. The treatment of macro stickies can be carried out by mixing the compound or chemical agent used in the present embodiment with the treatment object. In addition, the present embodiment may be a method for making macro stickies non-pressure adhesive or a method for reducing the pressure adhesiveness of macro stickies.In a more suitable treatment method for macro stickies, the cationic compound for positive conversion is used such that an amount larger than an amount which allows a macro stickies-containing object to undergo positive conversion is used (for example, added).The more suitable treatment method for macro stickies includes using (for example, adding) an amount of the cationic compound equal to or larger than an amount which allows a macro stickies-containing object to undergo positive conversion, and subsequently using (for example, adding) an anionic chemical agent and / or another slurry until the positive conversion is eliminated.In the present embodiment, the treatment object includes those including macro stickies, which are related to various steps in paper manufacturing, for example, various process water, various process slurries, and various process dewatered cakes. One or two or more selected from these treatment object can be targeted; however, the treatment objects are not limited to these.In the present embodiment, it is suitable that the macro stickies-containing object as a treatment object is a slurry (pulp-containing water) in a step of manufacturing paper using a used paper raw material. In particular, used paper (for example, newspapers, cardboard, magazines, or the like) to which the pressure adhesive tapes or labels are attached are used as the used paper raw material. Therefore, the larger amount the used paper is, the larger amount of components (suitably, a (meth)acrylate component) that are the source of macro stickies is contained. The macro stickies in the slurry which is obtained from used paper as a raw material are mainly undisintegrated pressure adhesives such as pressure adhesive tapes, labels, and adhesives, which contaminants, and the undisintegrated materials are removed by a screen or a cleaner. For this reason, macro stickies are concentrated in the rejected substances by the screen or the cleaner in the raw material step or paper making step. According to the present embodiment, such rejected substances can be used as a treatment object, thereby being reused as a raw material.According to the present embodiment, a slurry, a dewatered cake, pulp-containing water, or the like in paper manufacturing including a step of manufacturing paper using a used paper raw material, is treated as a treatment object, whereby macro stickies in the slurry or the dewatered cake in paper manufacturing can be more favorably treated.In addition, in the present embodiment, it is suitable that the macro stickies-containing object is a rejected substance that is generated by a screen or a cleaner in a raw material step or a paper making step in paper manufacturing. According to the present embodiment, the macro stickies in the rejected substance can be treated more favorably, which makes it possible to reuse, as a raw material, the rejected substance in which the macro stickies are concentrated. In this case, in consideration of treatment efficiency, it is preferable that the amount of macro stickies as a treatment object is 5,000 mm2 / kg or more.In the paper manufacturing step in the present embodiment, the step order or installation location of the dust removal step including the screen step and / or the cleaner step is not particularly limited, and one or a plurality of the dust removal steps may be provided and carried out in the paper manufacturing step. In addition, it may also be provided as appropriate in the preparation step and / or paper making step, or may be provided as appropriate after the step, before the step, or between the steps in order to remove trash and pitches contained in the object. In addition, since the rejected substance (or an object containing the rejected substance) after being rejected by the screen or the cleaner includes macro stickies, the macro stickies contained in the object can be treated more favorably by treating the rejected substance (or the object containing the rejected substance) according to the present embodiment.In addition, in the present embodiment, the amount of macro stickies in the macro stickies-containing object is not particularly limited. However, from the viewpoint of treatment efficiency, it is suitable that the suitable lower limit value thereof is preferably 100 mm2 / kg or more, more preferably 1,000 mm2 / kg or more, still more preferably 2,000 mm2 / kg or more, even still more preferably 3,000 mm2 / kg or more, and even further still more preferably 5000 mm2 / kg or more. In addition, although the suitable upper limit value thereof is not particularly limited by increasing and adjusting the adding amount of the chemical agent according to the content of macro stickies in the object, examples thereof include 100,000 mm2 / kg or less, 50,000 mm2 / kg or less, and 10,000 mm2 / kg or less.<Measuring method for amount of macro stickies (mm2 / kg)>In the present specification, the content of macro stickies (mm2 / kg) and macro stickies per 1 mm2in the present specification can be measured in accordance with JISP8231:2005.In addition, in the present embodiment, the adding amount of the treatment agent for macro stickies with respect to the macro stickies is not particularly limited; however, the suitable lower limit value thereof is preferably 0.0001 mg / mm2or more, more preferably 0.0005 mg / mm2or more, still more preferably 0.001 mg / mm2or more, and even still more preferably 0.005 mg / mm2or more with respect to the macro stickies. In addition, although the suitable upper limit value thereof is not particularly limited by increasing and adjusting the adding amount of the chemical agent according to the content of macro stickies in the object, examples thereof include 0.5 mg / mm2or less, or 0.1 mg / mm2or less with respect to the macro stickies. However, it is preferably 0.05 mg / mm2or less, and more preferably 0.01 mg / mm2or less with respect to the macro stickies from the viewpoints of the chemical agent cost and the like.In addition, in the present embodiment, the using concentration of the compound that is used in the present invention is not particularly limited; however, the suitable lower limit value thereof is preferably 5 mg / L or more, more preferably 10 mg / L or more, still more preferably 20 mg / L or more, even more preferably 30 mg / L or more, even more preferably 50 mg / L or more, even more preferably 100 mg / L or more, even more preferably 200 mg / L or more, and even still more preferably 300 mg / L or more. In addition, the suitable upper limit value thereof is not particularly limited. However, it is preferably 5,000 mg / L or more, more preferably 4,000 mg / L or less, and still more preferably 3,000 mg / L or less from the viewpoints of the chemical agent cost. The using concentration of the compound is in terms of "mg of the compound that is used in the present invention / 1 L of process water" in a case where the object is the macro stickies-containing process water.In addition, in the present embodiment, in a case where the cationic compound for positive conversion is used as a treatment agent for macro stickies, it is suitable that, with respect to a macro stickies-containing object, the cationic compound for positive conversion is used (for example, added) such that an amount thereof is equal to or larger than an amount which allows the object to undergo positive conversion. In the present embodiment, the cationic compound for positive conversion reacts more favorably with macro stickies contained in an object by subjecting the object to positive conversion, whereby the macro stickies can be treated. The present embodiment has an advantage in that the cationic compound that has reacted with the macro stickies after the object has been subjected to positive conversion does not separate again from the macro stickies. Therefore, the present embodiment has an advantage in that the reduced pressure adhesiveness state of the macro stickies that have reacted with the cationic compound for positive conversion is maintained even in a case where the object after positive conversion is further mixed with an anionic compound and / or another slurry.In addition, in the present embodiment, it is suitable to include using (for example, adding) the cationic compound for positive conversion with respect to a macro stickies-containing object such that an amount thereof is equal to or larger than an amount which allows the object to undergo positive conversion, and subsequently, using an anionic compound and / or another suitably (pulp-containing water) to the object until the positive conversion is eliminated.In the present embodiment, it is suitable that the evaluation (determination) on whether a compound can be used as a compound for the treatment agent for macro stickies is carried out using an evaluation method for treatment of macro stickies according to the relationship between peel strength (N) and adding amount (mg / L) in terms of the non-pressure adhesive effect on the pressure adhesive tape in [Examples] described later. For example, there is a case where a peel strength of a pressure adhesive tape decreases as the amount of the chemical agent used (for example, added) increases. More specifically, for example, there is a case where a difference between a peel strength (N) without addition and a peel strength (N) with a using amount of 3,000 mg / L is 0.5 or more or 1 or more; or a case where the negative slope is large.For the evaluation (determination) on whether a compound is the cationic compound for positive conversion, it is suitable to use the "evaluation method for treatment of macro stickies (the presence or absence of positive conversion)" carried out in [Example] described below. It is suitable to determine, as the "cationic compound for positive conversion", such a compound that one or two or more values selected from the peel strength (N), the amount of cations required (μeq / L), and the zeta potential (mV) have changed in a case where an amount of a chemical agent in a sample has increased sequentially. One example thereof includes such one that the peel strength (N) is 0.2 or less than 0.4 in terms of the comparison between without addition and addition, for example, in a case where the peel strength (N) is used; or such one that the amount of cations required changes from positive to negative and / or such one that the zeta potential changes from negative to positive between 0 to 300 mg / L, for example, in a case where the upper limit of the adding amount of the chemical agent is set to 300 mg / L. It is suitable to use at least the amount of cations required or the zeta potential as an indicator, and it is more suitable to use both of these as an indicator.In the present embodiment, it is suitable that the compound that is used in the present invention is used (for example, added) with respect to a macro stickies-containing object such that an amount thereof is larger than an amount which allows the macro stickies-containing object to undergo positive conversion. Further, in the present embodiment, an anionic compound and / or another slurry (object) can be further used (for example, added) to the macro stickies-containing object after the positive conversion treatment to eliminate positive conversion. Even after the positive conversion is eliminated, there is an advantage in that the reaction state between the macro stickies and the cationic compound can be maintained (specifically, the state of the reduced pressure adhesiveness of the macro stickies can be maintained).The measurement or monitoring of positive conversion in the present embodiment is suitably carried out by analyzing or measuring the amount of cations required and / or the zeta potential, and the analysis or measurement is suitably carried out by using an apparatus or method, a step, or the like, which is capable of measuring the amount of cations required and / or the zeta potential. The apparatus, method, step, or the like is not particularly limited; however, examples thereof include a commercially available measuring apparatus, a commercially available measuring kit, or a publicly known analysis method.The macro stickies-containing object used as a treatment object in the present embodiment includes, as described in "2." described above, pitch-containing water and the like, which contain macro stickies and the like, in the paper manufacturing step.

It is noted that the scope of the present invention is not limited to the following Examples.<Test Example 1>Since there are few macro stickies in an actual slurry, it is difficult to evaluate a treatment agent for macro stickies using the actual slurry. The degree of decrease in pressure adhesive force in the actual white water was compared with respect to a pressure adhesive tape, which is a main source of macro stickies in a used paper raw material. The pressure adhesive tape used for evaluation was an acrylate-based pressure adhesive tape, in which the main component of macro stickies is a pressure adhesive.<Evaluation method for treatment of macro stickies>On a glass plate having a vertical length of 25 mm, a lateral length of 75 mm, a thickness of 1 mm in thickness, a curing tape (Piolan Cloth pressure adhesive tape Y-09-GR, width: 25 mm) manufactured by DIATEX CO., LTD. is with the pressure adhesive side facing outward, and the glass plate on which the pressure adhesive tape has been fixed is placed to stand in a 200 mL beaker.White water (SS concentration: 0.15%, pH: 7.0) of a raw material step in a cardboard raw paper manufacturing factory is added to the 200 mL beaker in which the glass plate on which the pressure adhesive tape has been fixed, the white water (water temperature: 20°C, pH: 7.0, pulp content: 0.15%) in this beaker is stirred for 10 minutes with a magnetic stirrer, and the white water is brought into contact with the pressure adhesive surface of the pressure adhesive tape (chip length: 25 mm, rotation speed: 1,000 rpm) by stirring. A chemical agent (each of test chemical agents A to N) is added to the beaker while stirring, and the stirring is further maintained to bring the white water containing the chemical agents into contact with the pressure adhesive surface of the pressure adhesive tape by stirring. Thirty minutes after the addition, the glass plate on which the pressure adhesive tape has been fixed is taken out from the white water containing the chemical agent in the beaker, and the pressure adhesive tape which has been fixed on the glass plate is lightly washed with tap water. After the cleaning, the pressure adhesive tape was removed from the glass plate, the pressure adhesive side of the pressure adhesive tape was attached to a SUS plate (diameter: 100 mm), this SUS plate was sandwiched between two sheets of Water Absorption Filter Paper (NO 26, diameter: 185 mm) manufactured by Toyo Roshi Kaisha, Ltd. and pressed at 3.5 kgf / cm2for 1 minute. After the pressing, the filter paper was removed, the SUS plate attached with the pressure adhesive tape was disposed on a table and dried at room temperature (20°C to 30°C) for half a day (12 hours or more and 14 hours or less). Then, the pressure adhesive tape was peeled off from the SUS plate, and the peel strength was measured (measuring apparatus: STROGRAPHE-S, manufactured by Toyo Seiki Seisaku-sho, Ltd., peeling speed: 100 mm / min). Table 1 shows the composition of the evaluated chemical agent.The properties of the white water of the raw material step were such that the pulp content was 0.15% and the pH was 7.0.The average molecular weight of each of the chemical agents A to N was measured as follows.Chemical agents A, I, and J: GPC analysis, standard substance: polyethylene glycol (for weight average molecular weight)Chemical agents C, H, and M: GPC analysis, standard substance: polystyrene (for weight average molecular weight)Chemical agent E: Conversion from intrinsic viscosity is carried out (for an estimated average molecular weight based on the relationship between the intrinsic viscosity and average molecular weight)Chemical agents K and N: GPC analysis, standard substance: sodium polyacrylate (for weight average molecular weight)In addition, the degree of saponification, the average degree of polymerization, the colloidal equivalent, and the like for the chemical agent were measured using the various measurement methods described above (<Measuring method for degree of saponification>, <Measuring method for average degree of polymerization>, <Measuring method for colloidal equivalent value of cation)>, <Measuring method for intrinsic viscosity>, <Calculation method for estimated average molecular weight of water-soluble cationic polymer compound>, and the like).The test results are shown in Table 2 (Example 1-1 to Example 1-5, and Comparative Example 1-1 to Comparative Example 1-8).In the tests of polypropylene glycol (chemical agent A), triglyceride (chemical agent B), liquid paraffin (chemical agent C), and cationized PVA (a saponified copolymer product of vinyl acetate and diallyldimethylammonium chloride: chemical agent D), polyDADMAC (chemical agent E), a decrease in peel strength was observed. Therefore, polypropylene glycol (chemical agent A), triglyceride (chemical agent B), liquid paraffin (chemical agent C), cationized PVA (chemical agent D), and polyDADMAC (chemical agent E) reduced the pressure adhesiveness of the acrylate-based pressure adhesive tape in the actual white water. On the other hand, in the tests of high basic aluminum chloride (chemical agent F), bentonite (chemical agent G), a phenol resin alkaline solution (chemical agent H), and PVA (chemical agent L), which are general internally added pitch control agents, no decrease in peel strength was observed. It is noted that in the tests of the chemical agent A, the chemical agent B, and the chemical agent C, although polyoxyalkylene lauryl ether (chemical agent I) was blended at a weight ratio of 2% with respect to these chemical agents A to C in order to promote the dispersion thereof in white water, the chemical agent I itself had no action of reducing peel strength in the test of the chemical agent I.Although both the chemical agent A and the chemical agent H were polypropylene glycol compounds, the chemical agent A reduced peel strength, whereas the chemical agent H did not reduce peel strength. The chemical agent A has a solubility of less than 1 mg / L in water, and the chemical agent H, which has a molecular weight smaller than that of the chemical agent A, has a solubility of 10,000 mg / L or more in water. At an adding amount of 30 to 3,000 mg / L, where the evaluation was carried out, the chemical agent A did not dissolve in water and remained oily, but the chemical agent H dissolved in water. It was necessary for the chemical agent not to be dissolved but to be dispersed in water at the adding concentration in order to exhibit an effect.Although both the chemical agent C and the chemical agent M were hydrocarbon-based paraffins, the chemical agent C reduced peel strength, whereas the chemical agent M did not reduce peel strength. The chemical agent C is a liquid, and the chemical agent M, which has a molecular weight larger than that of the chemical agent C, is a solid. It was necessary for the chemical agent to be dispersed in water as a liquid oil at the using temperature (temperature of water) in order to exhibit an effect.The chemical agent A, the chemical agent B, and the chemical agent C were all liquid oils, and the chemical agent A, which was not soluble in water at the concentration where the evaluation was carried out, gave a small degree of decrease in peel strength as compared with the chemical agent A and the chemical agent B. The chemical agent A and the chemical agent B have a hydrophilic moiety (a hydroxyl group in the chemical agent A and a hydrophilic group of an acyl group in the chemical agent B) in the molecule thereof. An oil having a hydrophilic moiety was effective as compared with an oil having only a hydrophobic moiety such as a hydrocarbon.Although the chemical agent D and the chemical agent E dissolved in water, the peel strength was reduced. Both are cationic polymers. Although both the chemical agent D and the chemical agent L were PVA-based, the chemical agent L, which was not cationized, did not reduce peel strength. The chemical agent K, which was an anionic polymer, did not reduce peel strength either. For a chemical agent that dissolves in water, it was necessary to have a cationic group.Table 3 shows the peel strength and the state of positive conversion of the test liquid in a region where the amount of the added chemical agent E is small (Comparative Examples 2-1 to 2-5, and Examples 2-1 to 2-6). “○” in the column of positive conversion in Table 3 indicates that positive conversion has occurred. The state of positive conversion was determined from an amount of cations required in the supernatant liquid of the test liquid after being allowed to stand for 2 minutes, which had been measured using PCD 03 pH (Particle Charge Detector) manufactured by Mutek, and a zeta potential measured using LAZER ZEE METER MODERL 501 (a zeta potential measuring apparatus) manufactured by PEN KEM Inc. In a case where an amount of 25 mg / L or more of the chemical agent E was added, a decrease in peel strength was observed. Similarly, in a case where 25 mg / L or more of the chemical agent E was added, the positive conversion of the test liquid was observed. It was necessary for the cationic chemical agent to be added until positive conversion occurred, in order to obtain the effect of the cationic chemical agent.Table 4 shows the peel strength of the chemical agent D and the state of positive conversion of the test liquid (Comparative Example 3-1 and Examples 3-1 to 3-3). Although the chemical agent D was also a cationic chemical agent, a decrease in peel strength was observed at an adding amount where no positive conversion occurred.Table 5 shows the persistency of the non-pressure adhesive effect in a case where treatment was carried out with a cationic chemical agent (Examples 4-1 to 4-2, and Comparative Example 4-1). In Example 1, in which the test water of the pressure adhesive tape treated with the chemical agent E was replaced with chemical agent-free test water, a certain quantity of an effect of reducing peel strength remained. Even in Example 2, in which the chemical agent N as an anionic chemical agent was added to the test water of the pressure adhesive tape treated with the chemical agent E, thereby eliminating positive conversion, a certain quantity of an effect of reducing peel strength remained. In the comparative example in which the chemical agent N was added before the addition of the chemical agent E, the chemical agent E reacted with the chemical agent N and was consumed before reacting with the pressure adhesive tape. Therefore, almost no decrease in peel strength was observed.From these results, the inventors of the present invention found that in a case where one or more selected from an oily and fatty compound having a melting point of 50°C or less, polyvinyl alcohol having a cationic group, and a cationic compound used for positive conversion are used as a treatment agent for macro stickies, it is possible to reduce the pressure adhesiveness of macro stickies and the pressure adhesiveness derived from undisintegrated materials of pressure adhesive materials that cause the pressure adhesiveness. This technique makes it possible to prevent adhesion to the paper making machine or to prevent macro stickies from becoming coarse due to adhesion of macro stickies to each other or due to adhesion of undisintegrated materials of the pressure adhesive materials that cause the adhesion.In addition, the inventors of the present invention found that in a case where, with respect to macro stickies or an object containing undisintegrated materials of the pressure adhesive materials that cause the macro stickies, the cationic compound is added such that an amount of the cationic compound is equal to or larger than an amount which allows a macro stickies-containing object to undergo positive conversion, it is possible to reduce the pressure adhesiveness of macro stickies and the pressure adhesiveness derived from undisintegrated materials that cause the pressure adhesiveness of macro stickies. Further, it was found that even in a case where an anionic compound and / or another slurry is subsequently added until the positive conversion is eliminated, the effect of reducing pressure adhesiveness in macro stickies or undisintegrated materials of the pressure adhesive materials that cause the macro stickies can be maintained to some extent. As a result, it is considered that a certain degree of the effect of reducing pressure adhesiveness can be maintained even in the step after positive conversion. This technique makes it possible to prevent adhesion to the paper making machine or to prevent macro stickies from becoming coarse due to adhesion of macro stickies to each other or due to adhesion of undisintegrated materials of the pressure adhesive materials that cause the adhesion.In addition, from the above results, the present technique is considered to be a very useful technique even for such a slurry in a step of manufacturing paper using a used paper raw material, in which a large quantity of macro stickies or undisintegrated materials of pressure adhesive materials that cause the macro stickies are present, and even for a rejected substance generated by a screen or a cleaner in the raw material step or the paper making step in paper manufacturing.The point of the present technique is that the present technique targets macro stickies. In terms of a rule of thumb, in a case where the amount of macro stickies in the rejected substance for removing contaminants or in the raw material (process water) that contains a lot of pressure adhesives is 5,000 mm2 / kg or more, defects or equipment stains derived from macro stickies tend to be generated easily, and thus it is economically rational to carry out treatment of macro stickies for only such a raw material (process water) that has a large amount of macro stickies With the present technique, it is possible to carry out treatment of macro stickies even in such process water by increasing the adding amount of the treatment agent for macro stickies according to the present technique in accordance with such an amount of macro stickies. As a trial calculation of the adding amount of the chemical agent per amount of macro stickies, in a case where the minimum adding amount of the chemical agent is set to 30 mg / L, the maximum concentration of the addition target is set to 200,000 mg / L (= 0.2 kg / L), and the maximum amount of macro stickies is set to 150,000 mm2 / kg, the minimum adding amount of the chemical agent per amount of macro stickies can be calculated to be 30 / 0.2 / 150,000 = 0.001 mg / mm2. The present technique considers that the amount of macro stickies in an object is preferably 5,000 mm2 / kg or more in consideration of treatment efficiency. The suitable adding amount of the treatment agent for macro stickies in the present technique is considered to be suitably such that in terms of macro stickies per 1 mm2, the adding amount of the chemical agent is 0.001 mg or more, that is, 0.001 mg / 1 mm2or more with respect to the macro stickies. It is noted that the content of macro stickies (mm2 / kg) and macro stickies per 1 mm2in the present specification can be measured in accordance with JISP8231:2005.1 Paper manufacturing step10 Raw material2 Preparation step21 Dissolution step22 Dissociation step23 Dust removal step (cleaner step, screen step)24 Concentration step25 Beating step3 Paper making step31 Dust removal step32 Paper layer forming step33 Wet paper dewatering step34 Wet paper drying step4 Water recovery step41 Primary circulating water step42 Secondary circulating water step43 White water5 Paper6 Draining100 Treatment step, mechanism, or apparatus for macro stickies-containing object according to present embodiment
