Barley stone is a hydrated silicate mineral containing silica as a main component and contains sodium dioxide, alumina and the like. Since sodium ions are easily exchanged with cations such as calcium ions and magnesium, they have an effect of softening hard water. Yes, it is often used as a filter for water purifiers.

[0007] A hydrated silicate mineral containing aluminum, called zeolite, is called zeolite in Japan and is one of silicic ion-exchangeable substances that have long been used for softening hard water. Due to its porous structure, it has been used as a deodorant and a dehydrating / drying agent.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
It has a high far-infrared radiation function, has an antibacterial effect on staphylococci and Escherichia coli, and has a deodorizing effect on hydrogen sulfide and ammonia.

From the above viewpoint, the present inventor has adopted, as main materials, malt stone which is excellent in far-infrared radiation, antibacterial property and deodorizing property and zeolite which is excellent as a deodorant,
By mixing clay as a linking material into these two main materials, molding is facilitated, and by firing this, it has far-infrared radiation characteristics with excellent wear resistance and heat resistance, A molded article of far-infrared radiation ceramic having excellent composite functions such as antibacterial, deodorizing, purifying and antioxidant functions was obtained.

Hereinafter, the method for producing the far-infrared radiation ceramic of the present invention will be described in detail. Barley stone and zeolite as the main material and the mixed material of the ceramic molded body of the present invention,
Fe ₂ O ₃ , MnO ₂ , CoO and C
uO requires the use of fine powder. When the main material and the mixed material are mixed, the physical properties such as the specific gravity of each substance are different from each other, and since they are fine powders, agglomeration (so-called lumps are formed) and uniform mixing is not easy. .

Therefore, the main material, the clay serving as the connecting material, and each material serving as the mixing material are charged into a ball mill (stirring machine) at a predetermined mixing ratio, water is added, and the mixture is stirred. The mixture is then dewatered through a filter press. I do. Further, by adopting a means in which the dehydrated mixture is put into a vacuum-type kneading machine and kneaded, the main material and the respective materials serving as the mixing material are uniformly mixed, and a clay-like material that can be freely formed into a desired shape. (Hereinafter referred to as “ceramic dough”).

[0012] Then, this ceramic cloth is disc-shaped,
It is formed into a desired shape such as a rectangular plate or a sphere, and fired by an electric furnace (sintering machine) to obtain a far-infrared radiation ceramic molded body 1 of the present invention (see FIG. 1).

The ceramic dough according to the present invention is composed mainly of 20 to 30% by weight of crushed barite (biotite monzonite porphyry) and 15 to 25% by weight of zeolite and clay of 45 to 25% by weight.
Basically, 65% by weight and water are kneaded with the main material, but by adding Fe ₂ O ₃ , MnO ₂ , CoO and CuO, the hardness and heat resistance can be further increased, and high-temperature edible oil Among them, a ceramic molded body having sufficient heat resistance can be obtained.

The antibacterial effect of the far-infrared radiation ceramic of the present invention is as follows. The surface layer of microorganisms such as Escherichia coli and staphylococci is anions, and therefore has a neutral region (pH 7.0 to 7.0).
Although it is impossible to inhabit in only 5), since cations are generated by far-infrared radiation, the surface layer of the cells, which are anions, is destroyed by the cations, and at the same time, the protein of the cells is denatured. It becomes difficult to breathe and dies.

The mechanism of deodorization of the ceramic molded body with respect to ammonia and hydrogen sulfide is not a physical or chemical adsorption action, but a decomposition action based on far-infrared radiation, and is similar to a porous adsorbent such as activated carbon. Since it does not become saturated, the deodorizing power lasts semi-permanently.

A test on the adsorption ability of the far-infrared radiation ceramic according to the present invention to trimethylamine was conducted. In the test method, 20 g of the ceramic powder of the present invention and 40 ppm of trimethylamine were placed in a 1-liter Tedlar bag, and the residual concentration after a certain period of time was measured by a detector tube method. As the detection tube, (NO180 manufactured by Gastech Co., Ltd.)
R.NH2) was used. Table 1 shows the results.

[0017]

[Table 1]

As is apparent from Table 1, trimethylamine contained at 40 ppm which was not changed in the blank test was reduced to 5 ppm after 30 minutes by adding the far infrared radiation ceramic.

Similarly, an adsorption ability test for hydrogen sulfide was conducted. The test was performed in a 1-liter container.
8 g of a ceramic ball and 11.2 ppm of hydrogen sulfide were charged, and the concentration of residual hydrogen sulfide was measured after a certain period of time. Table 2 shows the results.

[0020]

[Table 2]

As apparent from Table 2, the initial 11.2p
The amount of hydrogen sulfide which was pm decreased to 3.8 ppm after 6 hours, and was 0.8 ppm after 24 hours, indicating that most of the hydrogen sulfide was decomposed by the ceramic balls.

When the ceramic molded body of the present invention was subjected to an elution test, it was found that heavy metals, arsenic (As), lead (P
No harmful substances such as b) and cadmium (Cd) were detected.

The far-infrared radiation ceramic of the present invention is basically used as a molded article formed in a spherical, disk-like or rectangular plate shape. For example, when used in a rice cooker,
You can cook delicious rice without yellowing for a long time.
Further, it can be used as an antioxidant for edible oil and as a deodorant for refrigerators and pots.

[0024] Further, those once solidified into a sphere or a plate can be ground into a granule or a powder and used as a soil conditioner or a deodorant for livestock manure. Further, it can also be used as a building material for spraying the granulated or powdered material under the floor or mixing it with the wall material to use for dehumidifying and deodorizing the house.

Next, an example of manufacturing a ceramic ball used for water purification will be described below.

EXAMPLE 1.25 kg of zeolite powder and 2.5 kg of clay were mixed with 1.25 kg of barley stone powder, and 20 liters of room temperature water were added and kneaded, followed by dehydration using a filter press and paste-like ceramic dough. I got Approximately 1000 spherical nuclei of about 4 g having a diameter of 12 to 14 mm are produced from this ceramic dough and dried, and the remaining ceramic dough is dried and then pulverized again to be powdered and mixed with water to make a muddy state. .

The spherical nuclei are arranged on a flat tray, and the mud is poured into the tray. The mud is adhered to the periphery while rolling the spherical nuclei, and after being air-dried for a while, the same operation is repeated several times. Was. The completed spherical body having a diameter of about 15 mm was placed in a drying furnace and completely dried, and then the dried spherical body was placed in an electric kiln for pottery molding and fired at 1100 ° C. for 30 minutes to obtain a ceramic ball.

Next, a water activating device using the ceramic ball as a filtering material will be described. As shown in FIG. 2, the main case 3 of the water activating device attached in the middle of the water pipe or the drain pipe is formed in a long cylindrical shape. And a ceramic ball 2 is filled therein.

Water or wastewater (hereinafter referred to as water)
The water quality is improved ionically by passing through the water activating device. That is, when the water passing through the water activating device passes through the ceramic ball 2, the ionization reaction is promoted to generate a large amount of hydroxy ions, and the water interface is at pH 7.0.
It becomes weakly alkaline of 0 to 8.0. For this reason, crystals formed by precipitation of calcium, silica, and the like at the interface of water with a large amount of hydroxyl ions are subjected to a surface-active action generated in the direction of ions. As a result, the form of the precipitated crystals becomes flakes with little adhesion, thereby preventing scale or the like from being formed on the inner wall of the pipe.

Since the ceramic ball 2 emits far-infrared radiation, the occurrence of algae amoeba is suppressed. Since the main body case 3 of the water activating device is made of stainless steel, the ionization effect of the ceramic ball 2 containing barley stone serving as a permanent microelectrode and the ion induction effect of the conductive and corrosion-resistant stainless steel are obtained. Together, they promote a mild surface-active effect on water. That is, the ionization reaction is promoted between the water molecules, and the clusters are activated small. The activated water produces a large amount of hydroxyl ions and exerts a surface-active action.

That is, when water passes through the ceramic balls 2 in the water activating device, a large amount of hydroxy ions are generated, so that the interface of the water becomes weakly alkaline with a pH of 7.0 to 8.0. Therefore, deterioration of water quality is prevented by the surface active effect, and problems due to scale adhesion and slime precipitation in the pipe waterway system are eliminated. Further, since the solid surface is washed while the passivation of the metal component is maintained, the generation of microorganisms such as Legionella bacteria is suppressed.

[0031]

As described above, according to the present invention, not only has a far-infrared effect, but also a complex function such as antibacterial, deodorizing, purifying, and antioxidant, and is excellent in moldability and durability. An infrared ceramic can be obtained.
