Description

[Technical Field]

[0001] The present invention relates to a ceramic material for CO2 fixation, a method for producing the same, and a method for CO2 fixation. [Background technology]

[0002] In recent years, the reduction of CO2 has become an urgent international issue due to the problem of global warming caused by the increase in CO2 in the atmosphere. In addition, the oxidation of seawater due to the increase in CO2 in seawater has also become a problem. Therefore, various methods for CO2 fixation technology are being considered as one of the methods for reducing CO2.

[0003] On the other hand, water containing mineral components is believed to have the potential to improve soil, promote plant growth, decompose harmful chemicals, deodorize, purify the air, and other beneficial effects, and various mineral-containing waters and production facilities for mineral-containing waters have been developed. The inventor has developed a mineral-containing water manufacturing device (A) that includes a means for immersing a conductive wire coated with an insulator and a mineral-donating material (A) in water, passing a direct current through the conductive wire, generating a water flow in the same direction as the direct current in the water around the conductive wire, and applying ultrasonic vibrations to the water to form a raw mineral aqueous solution (A), and a far-infrared generating means for irradiating the formed raw mineral aqueous solution (A) with far-infrared rays to form mineral-containing water (A) (see Patent Document 1). The inventors have also developed a mineral functional water production facility equipped with a mineral-containing water production device (B) that includes a mineral-containing water production device (A), multiple water-passing containers filled with different types of mineral-imparting materials (B), a water-transport path connecting the multiple water-passing containers in series, bypass water channels connected to the water-transport path in parallel with the multiple water-passing containers, and water flow switching valves provided at each branch point between the water-transport path and the bypass water channel (see Patent Document 2).The inventors have reported that the mineral functional water production facility can produce mineral functional water that has the function of emitting far-infrared rays with a characteristic wavelength (far-infrared-generating water).

[0004] On the other hand, even in the device reported in Patent Document 2, the types and blending ratios of the raw materials for the mineral components (mineral imparting materials) used in the mineral-containing water production devices (A) and (B) are particularly involved in a complex manner, and it was not necessarily clear what effects mineral functional water would have if a specific mineral imparting material was used. However, the inventors used the mineral functional water production equipment disclosed in Patent Document 2 and conducted extensive research, focusing on the types and blending ratios of the mineral imparting materials, and discovered that mineral functional water produced under certain conditions has excellent pest control effects against unicellular organisms (Patent Documents 3 and 4), a physical revitalizing effect (Patent Document 5), an effect of promoting the combustion of hydrocarbons (Patent Document 6), and an antioxidant effect (Patent Document 7).

[0005] The present inventors have also developed a technique for immobilizing mineral components derived from the above-mentioned mineral functional water onto a ceramic material (Patent Documents 8 and 9). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4817817 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-56366 [Patent Document 3] Patent No. 5864010 [Patent Document 4] Patent No. 6664707 [Patent Document 5] Patent No. 6030270 [Patent Document 6] Patent No. 6154085 [Patent Document 7] Patent No. 6185202 [Patent Document 8] WO2017 / 038972 [Patent Document 9] WO2016 / 038973 Summary of the Invention [Problem to be solved by the invention]

[0007] As mentioned above, various mineral-containing waters have been reported in the past, but the effects of many of them have not been scientifically proven, and the true effects of mineral-containing water have not yet been clarified in many areas. Therefore, there are many conventional mineral-containing waters that claim to have effects but do not actually have any effects, or that have effects that are insufficient for practical use or that have poor reproducibility of the effects. Even with the mineral functional water produced by the apparatuses reported by the present inventor in Patent Documents 1 and 2, it could not be said that the mineral functional water exhibiting the targeted effective effects was reliably produced. In particular, the types and blending ratios of the raw materials of the mineral components (mineral imparting materials) used in the mineral-containing water production apparatuses (A) and (B) reported in Patent Document 2 are intricately related, and the reality was that it was not necessarily clear what kind of mineral imparting material would be used to obtain mineral functional water with what kind of effects. Furthermore, the CO2 fixation effect of mineral functional water or ceramic materials using mineral functional water has not been studied until now.

[0008] Under these circumstances, an object of the present invention is to provide a ceramic material that contains components derived from mineral functional water and exhibits excellent CO2 fixation properties, and a method for producing the same. [Means for solving the problem]

[0009] As a result of extensive research to solve the above problems, the inventors discovered that a ceramic material containing mineral components contained in the specific mineral functional water (a) produced by the apparatus reported in Patent Document 2 and a calcium complex derived from the mineral functional water obtained by stopping the decomposition of raw materials during production using the same apparatus has excellent CO2 fixation properties, leading to the present invention.

[0013] The present invention will be described in detail below using examples, etc., but the present invention is not limited to the following examples, etc., and can be practiced with any modifications within the scope of the gist of the present invention. In this specification, the expression "to" is used to include the numerical values ​​or physical quantities before and after it. In addition, in this specification, the expression "A and / or B" includes "A only," "B only," and "both A and B."

[0014] <Ceramic material of the present invention> The present invention relates to a ceramic material for CO2 fixation (hereinafter referred to as "ceramic material of the present invention") that contains a component derived from mineral functional water and a calcium complex that has a Ca ion-donating function.

[0015] The ceramic material of the present invention is characterized by containing mineral components derived from mineral functional water and a calcium complex having a Ca ion-donating function (hereinafter, sometimes referred to as the "calcium complex of the present invention" or simply as the "calcium complex").

[0016] In this specification, the term "mineral functional water" refers to water that contains mineral components and exhibits at least one effective effect.

[0017] In this specification, "mineral-containing water" refers to raw water used in the initial stage of producing mineral functional water, and mineral-containing water also contains mineral components.

Note that mineral-containing water itself may or may not have effective effects.

[0018] In this specification, "mineral components" does not mean "inorganic components (including trace elements) excluding the four elements (carbon, hydrogen, nitrogen, and oxygen)" which is the narrow definition of minerals, but may contain the four elements (carbon, hydrogen, nitrogen, and oxygen) excluded in the narrow definition, provided that they coexist with inorganic components. Therefore, for example, "plant-derived mineral components" is a concept that includes plant-derived organic components as well as plant-derived inorganic components such as calcium. In addition, examples of inorganic components (constituting mineral components) include, but are not limited to, sodium, potassium, calcium, magnesium, and phosphorus, and trace elements such as iron, zinc, copper, manganese, iodine, selenium, chromium, and molybdenum.

The term "mineral components derived from mineral functional water" refers to the mineral components remaining after removing the solvent from the mineral functional water. However, as mentioned above, plant-derived mineral components include not only inorganic components but also organic components derived from plants.

[0021] Process (1): A process of immersing a conductive wire covered with an insulator and a mineral-imparting material (A) containing herbaceous plant raw materials consisting of herbaceous plants of the Asteraceae family and herbaceous plants of the Rosaceae family, and woody plant raw materials consisting of one or more woody plants selected from maple, birch, pine, and cedar, in water, passing a direct current through the conductive wire, generating a water current in the same direction as the direct current in the water around the conductive wire, imparting ultrasonic vibrations to the water to form a raw mineral aqueous solution (A), and then irradiating the raw mineral aqueous solution (A) with far infrared rays (wavelength 6 to 14 μm) to form mineral-containing water (A), wherein the amount of mineral-imparting material (A) added to the water is 10 to 15 wt %, and the current value and voltage value of the direct current passed through the conductive wire are in the ranges of 0.05 to 0.1 A and 8000 to 8600 V, respectively.

[0022] The method for producing the mineral functional water will be described in detail later.

[0023] Hereinafter, the mineral functional water suitable for use in manufacturing the ceramic material of the present invention will be the mineral functional water developed by the present inventors (sometimes referred to as "the mineral functional water of the present invention"). A common feature of the mineral functional water of the present invention is that it contains plant-derived mineral components (particularly plant-derived organic components).

[0024] As the mineral functional water, mineral functional water CAC-717 manufactured by Riken Technosystem Co., Ltd. is preferably used.

[0025] In the ceramic material of the present invention, the calcium ion-donating calcium complex preferably contains calcium carbonate and / or calcium bicarbonate and pectin and / or lignin. When the ceramic material of the present invention contains such a calcium complex, it becomes possible to immobilize CO2 as a deposit of calcium carbonate (CaCO3) by contacting the ceramic material with CO2.

[0026] It is known that the photosynthesis of symbiotic algae in the corals that form reefs (reef-building corals) causes an increase in the pH level within the coral, promoting skeletal growth. The ceramic material of the present invention may also cause a similar phenomenon, making it promising for use as so-called "artificial coral."

[0027] The ceramic material for CO2 fixation of the present invention can be broadly divided into the following two aspects. The first aspect of the ceramic material of the present invention is a solid obtained by drying a liquid containing mineral components and calcium complexes derived from mineral functional water, and the solid is used as is or after heating (unsupported). The ceramic material (first embodiment) of the present invention can be produced by the steps of: mixing mineral functional water (a) containing electromagnetic wave-emitting mineral components with mineral functional water (b) containing a calcium complex having a Ca ion-donating activity to obtain a liquid composition containing a calcium complex having a CO2 fixation activity; and evaporating the solvent from the liquid composition to obtain a solid.

[0028] A second embodiment of the ceramic material of the present invention is a support in which a mineral component derived from mineral functional water and a calcium complex are immobilized. The support may be any material capable of immobilizing the calcium complex. Suitable examples of the support include one or more selected from the group consisting of uncalcined limestone powder, uncalcined seashell powder, uncalcined diatom powder, pumice, and basalt powder extracted from the earth's crust.

[0029] Examples of the ceramic material (second embodiment) of the present invention include (1) a hardened cement body containing mineral components and calcium complexes derived from mineral functional water, (2) a porous ceramic body supporting mineral components and calcium complexes derived from mineral functional water, and (3) a fired ceramic body obtained by heating and firing the mineral components and calcium complexes derived from mineral functional water together with a support.

[0030] The ceramic material (second embodiment) of the present invention is preferably produced by a method including a step of immobilizing mineral functional water (a) containing electromagnetic wave-emitting mineral components and a calcium complex having Ca ion-donating properties on a support.

[0031] The ceramic material of the present invention can immobilize CO2 by contacting it directly or indirectly with a gas or liquid containing CO2. The method for immobilizing CO2 of the present invention includes a step of directly contacting the ceramic material of the present invention with air or water containing CO2. In this method, CO2 is directly immobilized in the ceramic material of the present invention.

[0032] Another embodiment of the CO2 fixation method of the present invention includes a step of dispersing the ceramic material of the present invention in water and contacting it with air containing CO2. In this method, the ceramic material of the present invention increases the pH of the water, increasing the amount of CO2 in the air that dissolves in the water. The CO2 dissolved in the water is fixed in the ceramic material dispersed in the water.

[0033] The "CO2-containing air" that is the target of the CO2 fixation method of the present invention is typically the atmosphere, but may be other air. The "CO2-containing water" that is the target is typically seawater, but may also be freshwater (rivers, lakes, marshes, etc.).

[0034] The "mineral components derived from mineral functional water" contained in the ceramic material of the present invention are preferably mineral components derived from mineral functional water (a). The term "mineral components derived from mineral functional water" refers to the mineral components remaining after removing the solvent components from the target mineral functional water. However, as mentioned above, plant-derived mineral components include not only inorganic components but also organic components derived from plants.

[0035] The calcium complex contained in the ceramic material of the present invention is preferably a calcium complex having a Ca ion-donating function, which contains calcium carbonate and / or calcium bicarbonate and pectin and / or lignin, as described above. While peat, for example, can be used as such a calcium complex, a calcium complex derived from mineral functional water obtained by stopping the decomposition of raw materials during the production of mineral functional water (hereinafter referred to as mineral functional water (b)), which will be described later, is preferred.

[0036] As the calcium complex of the present invention, a calcium complex derived from mineral functional water CAC-717PS-01 manufactured by Riken Technosystem Co., Ltd. is preferably used.

[0037] <Method of producing mineral functional water> Mineral functional water (a), which is suitable for use in producing the ceramic material of the present invention, can be produced using the apparatus disclosed in Patent Document 2 (JP 2011-56366 A) and by a method similar to that disclosed therein. Mineral functional water (b) can also be produced using the same apparatus by stopping the decomposition of the raw materials midway through production.

[0038] A preferred embodiment of the method for producing mineral functional water of the present invention, which uses the apparatus disclosed in Patent Document 2 (JP 2011-56366 A), will be described below with reference to the drawings. The following description corresponds to a method for producing mineral functional water CAC-717, manufactured by Riken Technosystem Co., Ltd., which is one type of mineral functional water (a). However, this is merely an example, and other mineral functional waters can be produced by appropriately changing the production conditions, including the raw materials. Furthermore, the mineral functional water (a) in the liquid composition of the present invention is not limited to mineral functional water CAC-717; other mineral functional waters can also be used depending on the desired biodegradation-like effect.

[0039] As shown in Figure 1, the mineral functional water production equipment 1 includes a mineral-containing water (A) production device 2, a mineral-containing water (B) production device 3, and a mixing tank 46, which is a mixing means for mixing mineral-containing water (A) 44 produced in the mineral-containing water (A) production device 2 with mineral-containing water (B) 45 produced in the mineral-containing water (B) production device 3 to form mineral functional water 47.

[0040] The mineral-containing water (A) manufacturing device 2 includes a raw mineral aqueous solution manufacturing means 10 that forms a raw mineral aqueous solution (A) 41 using water 11 supplied from the tap and a mineral-providing material (A) 12 (see Figure 4) described below as raw materials, and a far-infrared generation means 43 that irradiates the raw mineral aqueous solution (A) 41 obtained by the raw mineral aqueous solution manufacturing means 10 with far-infrared rays to change it into mineral-containing water (A) 44.

[0041] The mineral-containing water (B) manufacturing device 3 has the function of forming mineral-containing water (B) 45 containing mineral components eluted from the mineral-providing material by passing water W supplied from the outside through water-passing containers 51 to 56.

[0042] The mineral-containing water (A) production apparatus 2 and the mineral-containing water (B) production apparatus 3 will be described in detail below.

As shown in Figure 1, the mineral-containing water (A) production device 2 includes a raw mineral aqueous solution production means 10 (see Figure 2) that forms a raw mineral aqueous solution (A) 41 using water 11 supplied from a tap and a mineral imparting material (A) 12 (see Figure 4) described below as raw materials, and a far-infrared generation means 43 (see Figure 6) that irradiates the mineral-containing water (A) solution 41 obtained in the raw mineral aqueous solution production means 10 with far-infrared rays to change it into mineral-containing water (A) 44.

The DC power supply 17, ultrasonic generator 16, and circulation pump P are all powered by a general commercial power source.

[0045] The reaction vessel 13 is an inverted conical cylinder with an open top, and has a drain outlet 19 at the bottom, which corresponds to the apex. This drain outlet 19 is connected to a circulation path 18a that communicates with the suction port P1 of the circulation pump P, and directly below the drain outlet 19 are provided an opening adjustment valve 20 for adjusting the amount of water discharged into the circulation path 18a, and a drain valve 21 for discharging water and the like from the reaction vessel 13.

When the drain valve 25 is opened as needed, the water in the storage tank 22 can be discharged from the lower end of the drain pipe 24, and the temperature of the water 11 passing through the drain pipe 24 can be measured by the water thermometer 26.

[0048] As shown in FIG. 5, multiple conductive cables 29 (29a-29g), each consisting of a conductive wire 15 and an insulating material 14 covering the conductive wire 15, are wired in a circular shape at multiple positions at different depths within the reaction vessel 13, and each of these circular conductive cables 29a-29g is arranged approximately coaxially with the reaction vessel 13. The inner diameter of each of the conductive cables 29a-29g is gradually reduced to match the inner diameter of the inverted conical reaction vessel 13, and each has an inner diameter corresponding to the respective placement location. Each of the conductive cables 29a-29g is detachably connected to an insulating terminal 30 provided on the wall 13a of the reaction vessel 13, so that the circular portion can be removed from or attached to the terminal 30 as needed.

[0049] A cylindrical storage container 31 with a bottom made of an insulating mesh body is placed in a portion corresponding to the axis of the reaction container 13, and this storage container 31 is filled with the mineral-imparting material (A) 12. This storage container 31 is detachably fastened to the upper edge of the wall 13a of the reaction container 13 by a hook 31f provided on the top of the storage container 31.

[0050] 2, conductive cables 29s and 29t are spirally wound around the outer peripheries of the circulation paths 18a and 18b, respectively, and direct current DC is supplied to these conductive cables 29s and 29t from a DC power supply device 17. The direction of the direct current DC flowing through the conductive cables 29s and 29t is set to substantially coincide with the direction of the water flowing in the circulation paths 18a and 18b.

[0051] In the raw mineral aqueous solution producing means 10, a predetermined amount of water 11 is placed in the reaction vessel 13 and the storage tank 22, and the storage vessel 31 filled with the mineral-imparting material (A) 12 is set in the center of the reaction vessel 13. Then, the circulation pump P is operated, and the aperture adjustment valve 20 at the bottom of the reaction vessel 13 and the aperture adjustment valve 23 of the circulation path 18c are adjusted to circulate the water 11 from the reaction vessel 13 via the drain outlet 19, the circulation path 18a, the circulation pump P, the circulation path 18b, the storage tank 22, and the circulation path 18c, and back to the top of the reaction vessel 13. Then, the DC power supply 17 and the ultrasonic generating means 16 are operated, and the elution reaction of mineral components from the mineral-imparting material (A) 12 in the storage vessel 31 into the water 11 begins.

[0052] The working conditions for producing the raw mineral aqueous solution (A) using the raw mineral aqueous solution producing means 10 are not particularly limited, but in this embodiment, the raw mineral aqueous solution (A) was produced under the following working conditions. (1) A direct current DC of a voltage of 8000 to 8600 V and a current of 0.05 to 0.1 A was passed through the conductive cables 29, 29s, and 29t. The insulator 14 constituting the conductive cable 29 and the like was made of polytetrafluoroethylene resin. (2) The mineral-imparting material (A) 12 filled in the reaction vessel 13 is filled in an amount of 10 to 15% by mass relative to the water 11. A specific description of the mineral-imparting material (A) 12 will be given later. (3) The water 11 may contain an electrolyte so that the direct current DC can act on it. For example, about 10 g of sodium carbonate, an electrolyte, is dissolved in 100 liters of water, but groundwater can also be used as is. (4) The ultrasonic generating means 16 generates ultrasonic waves with a frequency of 30 to 100 kHz, and is positioned so that its ultrasonic vibration part (not shown) directly contacts and vibrates the water 11 in the reaction vessel 13.

[0053] When the raw mineral aqueous solution manufacturing means 10 is operated under these conditions, a water flow R is generated in the reaction vessel 13, which rotates in a left-handed screw direction and is sucked into the drain outlet 19, and the water 11 discharged from the drain outlet 19 returns to the reaction vessel 13 via the aforementioned circulation paths 18a, 18b, etc., and this state continues.

[0054] Therefore, due to the stirring action of the water flow R, the action of the direct current flowing through the conductive cable 29, and the ultrasonic vibrations applied to the water 11 by the ultrasonic generating means 16, the mineral components are quickly dissolved from the mineral-donating material (A) 12 into the water 11, and a raw mineral aqueous solution (A) in which the required mineral components are appropriately dissolved can be efficiently produced.

[0055] In the raw mineral aqueous solution producing means 10, a plurality of circular conductive cables 29a-29g are wired approximately coaxially within the reaction vessel 13, and a water flow R that rotates in a left-handed screw direction is generated within the reaction vessel 13. Therefore, a relatively dense electric energy field can be formed within the reaction vessel 13, which has a fixed volume, and the raw mineral aqueous solution (A) can be efficiently produced within the reaction vessel 13, which has a relatively small volume.

[0056] Furthermore, because reaction vessel 13 is in the shape of an inverted cone, it is possible to generate water flow R that flows along the plurality of circular conductive cables 29a-29g relatively easily and stably, thereby promoting the elution of mineral components. Furthermore, the flow rate of water flowing inside reaction vessel 13 in the shape of an inverted cone increases as it moves toward drain outlet 19 at the bottom of reaction vessel 13, which increases the frequency of contact with mineral-imparting material (A) 12 and increases the amount of minerals that are ionized by capturing free electrons e present in water 11.

[0057] Furthermore, since the storage tank 22 that stores and discharges the water 11 is provided between the circulation paths 18b and 18c, it is possible to proceed with the mineral elution reaction while circulating an amount of water 11 that exceeds the capacity of the reaction vessel 13. This allows for efficient mass production of the raw mineral aqueous solution (A).

[0058] By continuously operating the circulation pump P and continuing these reactions, a raw mineral aqueous solution (A) is eventually produced from which the mineral components have been eluted. The appearance of free electrons e in water 11 can be controlled by the size of the drain outlet 19 at the bottom of the reaction vessel 13, the amount of circulating water, and the shape of the reaction vessel 13 (particularly the angle γ between the axis C and the wall 13a shown in Figure 2), and the water solubility of the mineral components is determined by the effect of the free electrons e on the mineral-donating material (A) 12.

[0059] Once the raw mineral aqueous solution (A) is formed, this raw mineral aqueous solution (A) 41 is transferred into a treatment vessel 40 shown in Figure 6. In this case, any residue of the mineral-imparting material (A) 12 that has leaked from the storage container 31 in the reaction vessel 13 can be discharged through a drain valve 21 at the bottom of the reaction vessel 13. The raw mineral aqueous solution (A) 41 contained in the treatment vessel 40 is irradiated with far-infrared rays by a far-infrared generating means 43 arranged inside the treatment vessel 40 while being slowly stirred with a stirring blade 42.

[0060] The far-infrared generating means 43 may be any means that generates far-infrared rays with a wavelength of about 6 to 14 μm, and may be a heating type, regardless of the material or generating means. However, it is desirable that the radiation ratio of the far-infrared rays at 25°C is 85% or more of the blackbody radiation in the wavelength range of 6 to 14 μm.

[0061] In the raw mineral aqueous solution manufacturing means 10 shown in Figure 2, the mineral components contained in the mineral-donating material (A) 12 are quickly dissolved into the water 11 by the stirring action of the water flow R, the action of the direct current DC flowing through the conductive wire 15, and ultrasonic vibration, so that the required mineral components are appropriately dissolved, and the mineral aqueous solution 41 can be efficiently manufactured.

[0062] Then, in the far-infrared generating means 43 shown in Figure 6, by irradiating the mineral aqueous solution 41 with far-infrared rays, the dissolved mineral components and water molecules fuse together to form mineral-containing water (A) 44 with increased electronegativity.

[0063] In the mineral-containing water (A) manufacturing apparatus 2, the mineral-containing water (A) 44 formed by the above-mentioned process is sent to a mixing tank 46 via a water supply path 57y, as shown in Figure 1, and in the mixing tank 46 is mixed with mineral-containing water (B) 45 sent from the mineral-containing water (B) manufacturing apparatus 3.

[0064] The mineral-imparting material (A) will be described below. The mineral-donating material (A) contains herbaceous plant materials consisting of herbaceous plants of the Asteraceae family and herbaceous plants of the Rosaceae family, as well as woody plant materials consisting of one or more woody plants selected from maple, birch, pine, and cedar. The parts to be used are appropriately selected from parts that are easy to leach mineral components, such as leaves, stems, flowers, and bark, and may be used as is or as a dried product. Although other herbs other than those of the Asteraceae and Rosaceae families may be included, it is preferable that only herbs of the Asteraceae and Rosaceae families are included.

[0065] The mineral-donating material (A) may be a mineral-donating material (A'). The mineral-donating material (A') is a dried and pulverized product of a plant of the Asteraceae family, which is prepared by mixing 8 to 12% by weight of field thistle (leaves, stems, and flowers), 8 to 12% by weight of mugwort (leaves and stems), and 27 to 33% by weight of Japanese silverleaf (leaves and stems) as the herbaceous plant raw materials, drying the mixture, and pulverizing the mixture; The method uses dried and pulverized products of plants of the Rosaceae family, which are obtained by mixing, respectively, 17 to 23% by weight of Rosa multiflora (leaves and flowers), 8 to 12% by weight of Geum japonicum (leaves and stems), and 65 to 75% by weight of Rubus idaeus (leaves, stems, and flowers), drying the mixture, and pulverizing the mixture; a herbaceous plant material (A1) obtained by mixing the dried and pulverized product of the Asteraceae plant and the dried and pulverized product of the Rosaceae plant in a weight ratio of 1:0.8 to 1:1.2; As the woody plant raw material, maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) were mixed in proportions of 22 to 28% by weight, 22 to 28% by weight, and 45 to 55% by weight, respectively, and dried and then pulverized to obtain a woody plant raw material (A2). This mineral-imparting material is obtained by mixing herbaceous plant material (A1) and woody plant material (A2) in a weight ratio of 1:2.7 to 1:3.3.

[0066] Among the mineral-donating materials (A'), particularly preferred are herbaceous plant raw materials such as field thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) as the herbaceous plant raw materials, which are mixed in proportions of 10% by weight, 60% by weight, and 30% by weight, dried, and then pulverized, and herbaceous plant raw materials (A1) obtained by mixing, in a 1:1 (weight ratio), dried and pulverized products of plants of the Rosaceae family, which are mixed in proportions of 20% by weight, 10% by weight, and 70% by weight, dried, and then pulverized, and The woody plant raw material is preferably a mineral-imparting material obtained by mixing maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) in proportions of 25%, 25%, and 50% by weight, respectively, drying, and then pulverizing the mixture to obtain a dried and pulverized woody plant raw material (A2), and mixing the herbaceous plant raw material (A1) and woody plant raw material (A2) in a weight ratio of 1:3. As such herbaceous plant material (A1), "P-100 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used, and as woody plant material (A2), "P-200 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0067] In order to produce other mineral functional waters, the types of herbaceous plant raw materials (A1) and woody plant raw materials (A2) are changed. In addition, plant and animal species other than the herbaceous plant materials (A1) and woody plant materials (A2) can also be used as raw materials for mineral functional water.

[0068] (Mineral water (B) production equipment) Next, the structure, function, etc. of the mineral-containing water (B) production device 3 will be described with reference to FIGS. As shown in Figures 1 and 7, the mineral-containing water (B) manufacturing apparatus 3 includes a first water-passing container 51 to a sixth water-passing container 56 filled with different types of mineral-imparting material (B), a water supply path 57 connecting the first water-passing container 51 to the sixth water-passing container 56 in series, bypass water paths 51p to 56p connected to the water supply path 57 in parallel with the first water-passing container 51 to the sixth water-passing container 56, respectively, and water flow switching valves 51v to 56v provided at the branch points between each of the bypass water paths 51p to 56p and the water supply path 57.

[0069] The switching operation of the water flow switching valves 51v to 56v can be performed by operating six switching buttons 51b to 56b provided on an operation panel 58 connected to these water flow switching valves 51v to 56v by a signal cable 59. The six switching buttons 51b to 56b correspond to the six water flow switching valves 51v to 56v, respectively, so that operating any of the switching buttons 51b to 56b switches the water flow switching valve 51v to 56v with the corresponding number, thereby changing the water flow direction.

[0070] Here, the mineral-imparting materials (B) 51m to 56m can be preferably produced by mixing raw materials based on limestone, fossil coral, and seashells. First, the components contained in the limestone, fossil coral, and seashells are analyzed, and the amounts of silicon dioxide, iron oxide, activated carbon, titanium nitride, calcium carbonate, magnesium carbonate, and calcium phosphate are evaluated. Then, based on the content of each component, the limestone, fossil coral, and seashells are mixed to produce mineral-imparting materials (B) 51m to 56m. It is desirable to control the components contained in the mineral-imparting materials (B) 51m to 56m by adjusting the mixing ratio of limestone, fossil coral, and shells, but since the raw materials limestone, fossil coral, and shells may contain insufficient components depending on their place of origin, silicon dioxide, iron oxide, activated carbon, titanium nitride, calcium carbonate, magnesium carbonate, and calcium phosphate may be added as needed. In particular, activated carbon is rarely contained in limestone, fossil coral, and shells, so it is usually added separately.

[0071] As a mineral additive (B) 51m-56m, The mineral-providing material (B1) in the first water-passing container 51 is a mixture containing 70% by weight of limestone, 15% by weight of fossil coral, and 15% by weight of seashells, respectively; The mineral-providing material (B2) in the second water-passing container 52 is a mixture containing limestone, fossil coral, seashells, and activated carbon in amounts of 40 wt%, 15 wt%, 40 wt%, and 5 wt%, respectively; The mineral-providing material (B3) in the third water-passing container 53 is a mixture containing 80% by weight of limestone, 15% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-providing material (B4) in the fourth water-passing container 54 is a mixture containing 90% by weight of limestone, 5% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-providing material (B5) in the fifth water-passing container 55 is a mixture containing 80% by weight of limestone, 10% by weight of fossil coral, and 10% by weight of seashells, respectively; If the mineral-donating material (B6) in the sixth water-passing container 56 is a mixture containing 60% by weight, 30% by weight, and 10% by weight of limestone, fossil coral, and shells, respectively, it is possible to obtain mineral-containing water (B) that exhibits excellent pest control effects when mixed with mineral-containing water (A).

[0072] In particular, the limestone, fossil coral, and shells used in the mineral-imparting materials (B1) to (B6) are preferably the following (1-1) to (1-3).

[0073] (1-1) Limestone: Pebbles of about 3cm diameter made from crushed limestone mixed with volcanic deposits containing the following components: Calcium carbonate: 50% by weight or more Iron oxide: 3 to 9% by weight of iron Total of titanium oxide, titanium carbide, and titanium nitride: 0.8% by weight or more Magnesium carbonate: 7 to 10% by weight As such limestone, we use "CC-200 (product number)" manufactured by Riken Technosystem Co., Ltd. It can be suitably used.

[0074] (1-2) Fossil coral: The following two types of fossil coral were mixed in a weight ratio of 1:9 and crushed to 3-5 mm particles. This fossil coral was discovered about 100 meters underground and its crystalline composition has been altered by pressure. Fossil coral found on land near Amami Oshima, Okinawa (contains calcium carbonate, calcium phosphate, and other trace elements) As such fossil coral, "CC-300 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0075] (1-3) Shells: A granular material made by mixing equal amounts of abalone, tokobushi, and barnacles and crushing them to 3-5mm. As such a shell, "CC-400 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0076] (1-4)Activated carbon Activated carbon made from any raw material can be used, but activated carbon made from coconut shell is preferred. For example, "CC-500 (product number)" manufactured by Riken Technosystem Co., Ltd., which is made from coconut shell produced in Thailand, can be mentioned.

[0077] By operating the switch buttons 51b to 56b on the control panel 58 and switching the water flow selector valves 51v to 56v to the water container side, the water flowing through the water supply path 57 flows into the first to sixth water supply containers 51 to 56, which are located downstream of the operated water flow selector valves, and by switching the water flow selector valves 51v to 56v to the bypass water channel side, the water flowing through the water supply path 57 flows into the bypass water channels 51p to 56p, which are located downstream of the operated water flow selector valves. Therefore, by operating any of the switch buttons 51b to 56b and selectively switching the water flow selector valves 51v to 56v, it is possible to form mineral-containing water (B) 45 in which mineral components eluted from different mineral-imparting materials (B) 51m to 56m are selectively dissolved in the first to sixth water supply containers 51 to 56.

[0078] Next, the structure, functions, etc. of the actual mineral-containing water (B) production device 3 will be described with reference to Figures 8 to 11. Note that the aforementioned bypass water channels 51p to 56p, water flow switching valves 51v to 56v, operation panel 58, and signal cable 59 are omitted from Figures 8 to 10.

[0079] As shown in FIGS. 8 and 9, the mineral-containing water (B) manufacturing apparatus 3 includes first to sixth water-passing containers 51 to 56, each of which has a substantially cylindrical shape, mounted on a base 60, and a water supply path 57 connecting the first to sixth water-passing containers 51 to 56 in series. A raw water tank 63 for storing water W supplied from a mains water supply is disposed at the top of the base 60. The raw water tank 63 contains an inorganic porous body 64 capable of adsorbing impurities in the water W. A plurality of casters 61 and a level adjuster 62 are provided at the bottom of the base 60. The first to sixth water-passing containers 51 to 56, each of which has a substantially cylindrical shape, are mounted on the base 60, which has a rectangular lattice structure, with their respective axes 51c to 56c (see FIG. 9) maintained horizontally. The first to sixth water-passing containers 51 to 56 are detachable from the base 60.

[0080] As shown in Figure 10, the first through sixth water-passing containers 51 through 56 all have the same structure, with disk-shaped lids 51d through 56d attached to flanges 51f through 56f at both ends of the cylindrical main bodies 51a through 56a to form an airtight structure. A water inlet 57a, which communicates with the water supply path 57, is located at the bottom of the main bodies 51a through 56a when the axes 51c through 56c are horizontal. A water outlet 57b, which also communicates with the water supply path 57, is located at the top of the lid 51d through 56d furthest from the water inlet 57a, and a mesh strainer 57c is attached to the water outlet 57b. An automatic air valve 57d is attached directly above the water outlet 57b on the outer periphery of the main bodies 51a through 56a to release air from the first through sixth water-passing containers 51 through 56.

[0081] Water supplied from the upstream water supply path 57 passes through the water inlet 57a and flows into the first water supply container 51 to the sixth water supply container 56, and as it comes into contact with the mineral-imparting materials (B) 51m to 56m filled inside each, the respective mineral components are dissolved into the water, and the water contains mineral components corresponding to each mineral-imparting material (B) 51m to 56m, and flows out of the water outlet 57b into the downstream water supply path 57.

[0082] In the mineral-containing water (B) manufacturing apparatus 3 shown in Figures 8 to 10, by operating any of the switch buttons 51b to 56b on the operation panel 58 shown in Figure 7, water W from the raw water tank 63 can be passed through one or more of the first water-passing container 51 to the sixth water-passing container 56, thereby forming mineral-containing water (B) 45 in which the characteristic mineral components contained in the mineral-providing materials (B) 51m to 56m filled in the first water-passing container 51 to the sixth water-passing container 56, respectively, are selectively dissolved.

[0083] Furthermore, in the mineral-containing water (B) manufacturing device 3, the first water-passing container 51 to the sixth water-passing container 56 are connected in series by the water supply path 57, so that by continuously flowing water through the water supply path 57, it is possible to mass-produce mineral-containing water (B) 45 in which mineral components corresponding to the mineral-imparting materials (B) 51m to 56m in the first water-passing container 51 to the sixth water-passing container 56 are dissolved.

[0084] The mineral-containing water (B) 45 formed in the mineral-containing water (B) manufacturing apparatus 3 is sent into the mixing tank 46 via the water supply path 57x downstream of the sixth water supply container 56, and inside the mixing tank 46, it is mixed with the mineral-containing water (A) 44 produced in the mineral-containing water (A) manufacturing apparatus 2 shown in Figure 1 to form mineral functional water 47.

[0085] The blending ratio of mineral-containing water (A) to mineral-containing water (B) is determined appropriately taking into consideration the types of raw materials contained in mineral-containing water (A) and mineral-containing water (B) and the concentrations of the components that will be dissolved, but the weight ratio of mineral-containing water (A) to mineral-containing water (B) ([mineral-containing water (A)]:[mineral-containing water (B)]) is in the range of 1:5 to 1:20, preferably in the range of 1:7 to 1:12, and more preferably in the range of 1:10. If there is too little mineral-containing water (A) (too much mineral-containing water (B)), or if there is too much mineral-containing water (A) (too little mineral-containing water (B)), the active ingredients of the mineral functional water may be diluted, resulting in an insufficient desired effect.

[0086] <Mineral functional water (b)> The mineral functional water (b) is a mineral functional water containing a calcium complex having a Ca ion-donating function, which is obtained by stopping the decomposition of the raw materials during the production of the above-mentioned mineral functional water (a).

[0087] In the method for producing the mineral functional water (a) described above, the plant raw materials are completely decomposed to form a solution, but by stopping the production of the mineral functional water (a) midway before the plant raw materials are completely decomposed, the mineral functional water (b) is produced as a dispersion liquid in which a complex (calcium complex) of calcium carbonate and / or calcium bicarbonate derived from the plant raw materials with pectin and / or lignin is dispersed.

[0088] As the mineral functional water (b), mineral functional water manufactured by Riken Technosystem Co., Ltd., such as mineral functional water CAC-717PS-01 manufactured by Riken Technosystem Co., Ltd., can be suitably used.

[0089] The above describes a preferred embodiment of the method for producing the ceramic material (liquid composition, mineral functional water) of the present invention, but it should be understood that the present invention is not limited to the above-described preferred embodiment and various configurations can be adopted as long as the desired ceramic material (liquid composition, mineral functional water) of the present invention can be produced. In particular, matters not explicitly disclosed in the presently disclosed embodiment, such as operating conditions, operational conditions, various parameters, dimensions, weights, and volumes of components, do not deviate from the scope of ordinary skill in the art, and values ​​that can be easily assumed by a person of ordinary skill in the art can be adopted. [Example]

[0090] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples.

[0091] <1. Production of liquid composition> [Example] [1] Mixing process [1-1] Mineral functional water (a) As the raw material mineral functional water (a), mineral functional water CAC-717 (Terra Protect (product name), CAC-717 (product number), development product number CA-C-01) manufactured by Riken Technosystem Co., Ltd. was used.

[0092] Mineral functional water (a) (CAC-717) was produced using the mineral functional water production apparatus described in the embodiment of the present invention and the above-mentioned production method, using the following raw materials and method. Note that this method corresponds to the mineral functional water production method described in Example 1 of Japanese Patent No. 5864010.

[0093] 1. Production of mineral-containing water (A) As raw materials for the mineral-donating material (A), "P-100 (product number)" manufactured by Riken Technosystem Co., Ltd. was used as the herbaceous plant raw material (A1), and "P-200 (product number)" manufactured by Riken Technosystem Co., Ltd. was used as the woody plant raw material (A2). "P-100" is a herbaceous plant material (A1) made by mixing the following dried and ground Asteraceae plants and dried and ground Rosaceae plants in a 1:1 (weight ratio), and "P-200" is the woody plant material (A2) described below. (A1) Herbaceous plant materials (dried herbaceous plants) (A1-1) Dried and crushed Asteraceae plants This product is made by mixing wild thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) in proportions of 10%, 60%, and 30% by weight, respectively, drying, and then pulverizing. (A1-2) Dried and crushed Rosaceae plants This product is made by mixing wild rose (leaves and flowers), geum japonicum (leaves and stems), and rubus fruticosus (leaves, stems, and flowers) in proportions of 20%, 10%, and 70% by weight, respectively, drying, and then pulverizing. (A2) Woody plant materials (dried woody plants) Maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) are mixed in proportions of 25%, 25%, and 50% by weight, respectively, dried, and then crushed.

[0094] The mineral-providing material (A), a 1:3 (by weight) mixture of herbaceous plant material (A1) and woody plant material (A2), was added to the raw mineral aqueous solution producing means 10 (see FIG. 2) of the mineral-containing water (A) producing apparatus 2 shown in FIG. 1 at a concentration of 10-15% by weight of water. A direct current (DC 8300 V, 100 mA) was passed through the conductive wire of the raw mineral aqueous solution producing means 10, generating a water flow in the same direction as the DC current in the water surrounding the conductive wire. Ultrasonic vibrations (oscillation frequency 50 kHz, amplitude 1.5 / 1000 mm) were applied to the water to form the raw mineral aqueous solution (A). The raw mineral aqueous solution (A) was then supplied to the downstream far-infrared generating means 43, where it was irradiated with far-infrared rays (wavelength 6-14 μm) to obtain the mineral-containing water (A) of the present example. In the mineral-containing water (A), the raw materials, the herbaceous plant material (A1) and the woody plant material (A2), were almost completely decomposed, and almost no solid matter was visible to the naked eye.

[0095] 2. Production of mineral-containing water (B) The raw material for mineral-imparting material (B) was a crushed and mixed mixture of limestone, fossil coral, seashells, and activated carbon. The raw materials for mineral-imparting material (B) and the mixtures used in the first to sixth water-passing vessels (mineral-imparting materials (B1) to (B6)) are as follows: (1) Raw materials (1-1) Limestone: "CC-200 (product number)" manufactured by Riken Techno Systems Co., Ltd.

[0096] In the mineral functional water production facility 1 shown in Figure 1, mineral-containing water (B) was obtained by passing water through the first to sixth water-passing vessels containing the mineral-providing materials (B1) to (B6). Each of (B1) to (B6) was 50 kg (300 kg in total), and the amount of water passed through was set to 1000 kg, with a flow rate of 500 mL / 40 s.

[0097] The mineral-containing water (A) and the mineral-containing water (B) prepared by the above method were mixed in a weight ratio of 1:10 to obtain mineral functional water (CAC-717).

[0098] When the mineral functional water (a) was measured with a pH meter (Toko Chemical Laboratory glass electrode type hydrogen ion concentration indicator TPX-90), the pH was 12.5.

[0099] Figure 12 shows the spectral emissivity spectrum of mineral functional water (a) and the spectral emissivity spectrum (theoretical value) of a black body (measurement temperature: 25°C, wavelength range: 4-24 μm, reference carrier: ceramic powder). Figure 13 shows the emissivity ratio of mineral functional water (a) to a black body at 25°C. The spectral emissivity evaluation The spectral emissivity of the sample in which the mineral functional water of Example 1 was immobilized on a ceramic carrier was measured using a far-infrared emissivity measuring device (JIR-E500 manufactured by JEOL Ltd.) The device is composed of a Fourier transform infrared spectrophotometer (FTIR) main body, a blackbody furnace, a sample heating furnace, a temperature controller, and an auxiliary optical system.

[0100] [1-2] Mineral functional water (b) As the mineral functional water (b), the mineral functional water "CAC-717PS-01" manufactured by Riken Technosystem Co., Ltd. was used.

[0101] The mineral functional water (b) was produced by the following procedure. In the production of the mineral functional water (a) described above, the same (A1) herbaceous plant raw materials and (A2) woody plant raw materials were used as in the production of "1. Mineral-containing water (A)," and the decomposition was stopped when solids could be visually confirmed (treatment time: approximately 3 hours), thereby producing mineral functional water (b) containing a calcium complex in which calcium components (calcium carbonate and / or calcium bicarbonate) remained in the pectin and / or lignin derived from the (A1) herbaceous plant raw materials and (A2) woody plant raw materials.

[0102] <2. Manufacturing of ceramic materials for CO2 fixation> Ceramic materials (unfired ceramics) A clay-like mixture was obtained by adding 100 parts by weight of mineral functional water (a) to 100 parts by weight of limestone powder as a ceramic powder carrier. The resulting clay-like mixture was molded, and then 10 parts by weight of mineral functional water (b) was uniformly impregnated into the mold. The mixture was then dried to obtain the ceramic material of Example 1, in which the mineral components contained in the mineral functional water (a) and the calcium complex derived from the mineral functional water (b) were immobilized.

[0103] <Evaluation> Assuming that the ceramic material of the present invention will be used on land and in seawater, a CO2 fixation (absorption) demonstration experiment was carried out in the following manner. The ceramic material used was the ceramic material of Example 1 described above.

[0104] (Experimental Example 1: Land) A box of a specified size (30 x 30 x 30 cm) was filled with 400 g of ceramic material and air, then sealed, and the CO2 concentration inside the box was monitored over time (60 minutes). As a reference example, a similar evaluation was also performed using only air without the ceramic material. The results are shown in Figure 14.

[0105] (Experimental Example 2: Water system) A liquid prepared by dispersing 50 g of the ceramic material of Example 1 in 100 g of seawater and air were placed in a box of a specified size (12 x 12 x 30 cm), then sealed. The CO2 concentration (gas phase) inside the box was monitored over time (60 minutes). As a reference example, a similar evaluation was performed using 100 g of seawater and air without the ceramic material. The results are shown in Figure 14.

[0106] As shown in Figure 14, the CO2 concentration in the Reference Example did not change over 60 minutes, whereas the CO2 concentration in both Experimental Example 1 (land system) and Experimental Example 2 (aquatic system) decreased over time. From these results, the CO2 absorption effect of the ceramic material of the present invention was confirmed in the initial evaluation in both aquatic and terrestrial systems.

[0107] (Experimental Example 3: Water system) The water-based experiment of Experimental Example 2 was repeated five times in succession, and the results are shown in FIG. As shown in Figure 16, it was confirmed that there was no significant decrease in CO2 absorption capacity when the same ceramic material was used for repeated evaluation. [Industrial Applicability]

[0108] The ceramic material of the present invention has excellent CO2 fixation properties due to the mineral components it contains, making it a promising CO2 fixation material. [Explanation of symbols]
