Description

Technical Field

[0001] The utility model relates to the technical field of papermaking felts, in particular to a pollution-resistant, corrosion-resistant and easy-to-clean papermaking felt. Background Art

[0002] The fabric felt used for paper forming and conveying in the papermaking industry can be divided into wet felt, upper felt and dry felt according to its position on the papermaking machine. The felt runs with water on the papermaking machine to press the paper blank to dehydrate it and make the paper surface smooth. The wet felt has good water filtration and elasticity, high strength, small shrinkage, wear resistance, and resistance to bacteria and acid and alkali corrosion. The felt is used above the wet felt, with a small part in contact with the drying cylinder, which plays the role of paper leading, leveling and drying.

[0003] At present, the existing papermaking felts are easily stained and difficult to clean during use, which can easily contaminate paper during use. At the same time, the structural strength of the felts is low. When loaded, the felts are easily torn under the action of tension. At the same time, when the papermaking felts are affected by open flames, they are easily ignited and burned due to their low ignition point, resulting in the need to improve the use effect of the existing papermaking felts.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: an anti-fouling, anti-corrosion and easy-to-clean papermaking felt, comprising an anti-slip layer 1, a base fabric layer 2 is fixedly connected to the top of the anti-slip layer 1, a reinforcing layer 3 for reinforcing the tensile performance of the papermaking felt is fixedly connected to the top of the base fabric layer 2, a PP layer component 4 for reinforcing the strength of the papermaking felt is installed on the top of the reinforcing layer 3, a moisture-absorbing layer 5 for keeping the papermaking felt dry and absorbing moisture is installed on the top of the PP layer component 4, a flame-retardant layer component 6 for preventing fire is installed on the top of the moisture-absorbing layer 5, and a woven layer 7 for improving the toughness of the papermaking felt is installed on the top of the flame-retardant layer component 6, through the base fabric layer on the anti-slip layer 1 2. The mutual coordination between the reinforcing layer 3, the PP layer assembly 4, the moisture absorbing layer 5, the flame retardant layer assembly 6 and the woven layer 7 makes it light in texture and convenient for users to clean it. At the same time, it can effectively enhance the strength of the papermaking felt, improve the shear resistance, and further prevent the problem of moisture and mold after long-term use. At the same time, when the papermaking felt is affected by open flames, the coating applied to the outer surface of the papermaking felt will perform fire prevention work, so that the ignition point of the papermaking felt is increased, so even if it is affected by open flames, it will not cause the papermaking felt to be ignited, thereby effectively improving the use effect of the existing papermaking felt.

[0026] In this embodiment, the PP layer assembly 4 is a structure for enhancing the strength of the papermaking felt.

[0027] like Figure 1 and Figure 2As shown, the PP layer assembly 4 includes a resin layer 41 fixedly connected to the top of the reinforcing layer 3 , a UV absorbing layer 42 fixedly connected to the top of the resin layer 41 , and an anti-oxidation layer 43 fixedly connected to the top of the UV absorbing layer 42 .

[0028] It should be noted that the top of the anti-oxidation layer 43 is fixedly connected to the bottom of the moisture absorbing layer 5, and the resin layer 41, the ultraviolet absorbing layer 42 and the anti-oxidation layer 43 are all bonded and fixed by high-temperature resistant glue, in order to make the resin layer 41, the ultraviolet absorbing layer 42 and the anti-oxidation layer 43 connected more tightly.

[0029] It can be understood that the resin layer 41, the ultraviolet absorption layer 42 and the anti-oxidation layer 43 are all in a torn mesh structure in order to increase the softness of the binding rope.

[0030] In this embodiment, the flame retardant layer assembly 6 is a structure for preventing fire when it is affected by open flames.

[0031] like Figure 1 and Figure 3 As shown, the flame retardant layer assembly 6 includes a metal layer 61 fixedly connected to the top of the moisture absorbing layer 5, a flame retardant coating 62 fixedly connected to the top of the metal layer 61, a nylon fiber layer 63 fixedly connected to the top of the flame retardant coating 62, and a polyester fiber layer 64 fixedly connected to the top of the nylon fiber layer 63.

[0032] It should be noted that the metal layer 61 is composed of a metal wire nano coating and a metal wire mesh layer, and the metal wire nano coating and the metal wire mesh layer are bonded and fixed by hot pressing in order to ensure the overall toughness of the papermaking felt.

[0033] It is understandable that the metal layer 61, the flame retardant coating 62, the nylon fiber layer 63 and the polyester fiber layer 64 are all bonded and fixed by high temperature resistant glue in order to make the metal layer 61, the flame retardant coating 62, the nylon fiber layer 63 and the polyester fiber layer 64 connected more tightly.

[0034] In this embodiment, the woven layer 7 is a structure used to improve the toughness and tensile strength of the papermaking felt.

[0035] like Figure 1 and Figure 4 As shown, the braided layer 7 includes a rhombus braided layer 71 fixedly connected to the top of the polyester fiber layer 64 , and a warp and weft braided layer 72 is fixedly connected to the top of the rhombus braided layer 71 .

[0036] It should be noted that the diamond braided layer 71 and the warp and weft braided layer 72 are both bonded and fixed by high temperature resistant glue in order to make the diamond braided layer 71 and the warp and weft braided layer 72 connected more tightly.

[0037] The working principle of the above embodiment is:

[0038] When the papermaking felt is pulled, the rhombus woven layer 71 and the warp and weft woven layer 72 can improve the tensile strength of the papermaking felt, and will not cause damage to the papermaking felt, thereby reducing losses. When the papermaking felt is affected by an open flame, the flame retardant layer assembly 6 coated on the papermaking felt will work. First, when the open flame touches the flame retardant coating 62 and the metal layer 61, the ignition point can be increased due to the combination of the flame retardant coating 62 and the metal layer 61. Then, the nylon fiber layer 63 and the polyester fiber layer 64 are used in combination to prevent them from being easily torn apart. In addition, when in use, the base fabric layer 2, the reinforcement layer 3 and the PP layer assembly 4 are used in combination to prevent the papermaking felt from breaking easily after long-term use. Then, when encountering a moisture-proof environment, the moisture absorbing layer 5 can be used to absorb moisture to prevent the problem of moisture and mold after long-term use.

[0039] Compared with the prior art: the anti-fouling, anti-corrosion and easy-to-clean papermaking felt, through the mutual cooperation of the base fabric layer 2, the reinforcing layer 3, the PP layer assembly 4, the moisture-absorbing layer 5, the flame-retardant layer assembly 6 and the woven layer 7 on the anti-slip layer 1, makes it light in texture and convenient for users to clean it. At the same time, it can effectively enhance the strength of the papermaking felt, improve the shear resistance, and further prevent the problem of moisture and mold after long-term use. At the same time, when the papermaking felt is affected by open flames, the coating applied on the outer surface of the papermaking felt will perform fire prevention work, so that the ignition point of the papermaking felt is improved, so even if it is affected by open flames, the papermaking felt will not be ignited, thereby effectively improving the use effect of the existing papermaking felt and solving the problem of poor use effect of the existing papermaking felt.

[0040] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
