The manufacturing method of the multifunctional health tile of the present invention will be described in more detail with reference to FIG. 3 showing a dry molding method and FIG. 4 showing a wet molding method.

As shown on the left side of Figure 3, the manufacturing method of the health tile according to the present invention produced by the single firing method of the dry molding method first collects the natural loess, clay, diatomaceous earth in the clay stage, and generated as a by-product from the thermal power plant Bituminous coal or anthracite fly ash, and recycled raw materials such as crushed glass, soda silicate, and lignin tannin are weighed in a specified amount and put together with water in a ball mill for grinding. At this time, the specific gravity of the produced slip is about 1.45 to 1.6, and the residual ratio is about 1 to 3% / 230mesh. After aging this slip for at least one day, a granulated powder is produced in which a spray dryer has a water content of 5.5 to 6.5%, a grain size of 15 mm or less, and a grain size of 0.08 mm or less. do.

Subsequently, in the dry forming step, the granule powder is molded in a hydraulic press at a seal molding pressure of 250 to 350 kg / cm 2. Subsequently, in the drying step, the dry molded green tile is dried in a drying chamber (Vertical Dryer or Mangle Dryer) at a drying temperature of 100 to 150 ° C. and a drying time of 55 to 65 minutes. Subsequently, in the oiling step, the glaze is applied to the dried upper surface of the green tile. The glaze application step is to apply frit glaze with a coating amount in the range of 100 to 140 gr / m2, or to print the glaze paste by selecting a mesh size (24HD to 170T) according to the design or to apply frit glaze to 100 to 140 gr / m2.

As shown in the right side of Figure 3, the manufacturing method of the health tile according to the present invention to produce a double firing method of the dry molding method, characterized in that the primary firing instead of the drying step of the single firing method In this first firing step, the biscuit tiles are manufactured in a continuous firing kiln in which the dry-molded green tile has a maximum firing temperature of 600 to 900 ° C., a maximum holding time of 0.5 to 5 minutes, and a total firing time of 30 to 40 minutes. It is done. In the following sieving step, the steps up to the finished product are performed in the same way as the single firing method.

In addition, as shown in Figure 4, the manufacturing method of the wet tiles of the wet molding method according to the present invention, in the combination, milling step, the weight of the tile material as described above in the ball mill for fine grinding Put together and run, and let slips mature for at least one day. Subsequently, in the filtering step, a cake having a water content of 20 to 30% is produced in a filter press. Subsequently, in the coma kneading step, the cake is naturally dried, and then mixed with water and a pigment after crushing in a crusher for injection molding. Subsequently, in the injection molding step, the semi-kneaded clay is manufactured by injection molding through a feed box. Subsequently, in the drying step, the injection molded semi-finished product is dried under the conditions of a drying temperature of 100 to 150 ℃. Subsequently, in the milking step, the glaze is characterized. Hereinafter, the steps from the firing step to the finished product are the same as in the dry forming method.

In addition, the crystal structure of the natural ocher used in the present invention is a three-layer structure having a 2: 1 layered structure consisting of a tetrahedral sheet (tetrahedral sheet: tetrahedron) composed of Si and O bonds and Al and O bonds. Octahedral sheet (octahedral sheet) is a 2: 1 type structure in which three sheets are repeatedly overlapped to form one layer like tetrahedral-octahedron- tetrahedron sheets. Such structural characteristics of loess are caused by negative charges from loess due to homomorphic substitution of Al ⁺³ ions instead of Si ⁺⁴ ions in tetrahedron and Mg ⁺² and Fe ⁺² instead of Al ⁺³ and Fe ⁺³ ions In order to neutralize the negative charge, Na ⁺ , Ca ^{+ 2} and H ⁺ ions are weakly attached to the tetrahedron, so that far infrared rays are radiated.

In addition, the fly ash used in the present invention has a main chemical composition of SiO ₂ , Al ₂ O ₃ , carbon and the main crystalline phase is composed of quartz (SiO ₂ ), mullite (3Al ₂ O ₃ · 2SiO ₂ ). The crystal structure is present in the form of Cenosphere and aggregates of spherical particles, which are hollow and have a particle size of several micrometers to several hundred micrometers. These spherical particles make the material into a microporous form to absorb or release moisture. The cenosphere is formed by the expansion of the CO ₂ gas generated by the chemical reaction of unburned carbon and Fe ₂ O ₃ as the molten silicate particles are burned by anthracite or bituminous coal in a combustion furnace of a thermal power plant. The carbon present in the fly ash as unburned carbon helps to be more porous through the sintering process in the material. This microporous structure provides a moisture absorption and moisture proof effect.

The crushed glass (Cullet) used in the present invention has a property of melting at a low temperature is used as a low-temperature sintering binder in the composition.

According to the present invention, since the surface of the tile product is glazed and color printed, it is not only aesthetically sensitized, but a photocatalytic antimicrobial agent containing silver or copper is coated on it to provide a deodorizing effect and to suppress the growth of bacteria and mold. Can be.
