Description

Far infrared loess tile and its manufacturing method {LOESE TILE AND IT'S MANUFACTURING METHOD}

The present invention relates to a far-infrared yellow ocher tile and a method for manufacturing the same, which can freely adjust the humidity of an indoor space in order to obtain a comfort level most suitable for a human body in a living space.

Conventionally, there were many types of ceramic tiles, but most of them are oil-based interior tiles, oil-free Doc tiles, and exterior tiles, and the surface is composed of a glaze layer.

Such ceramic tiles have dew condensation on the surface of the tile glaze in a high humidity room, thus causing mold on the walls, thereby providing a major cause of a dirty indoor environment such as disease of the respiratory system of the human body.

In addition, when the humidity is low, the humidity of the room is increased by using a humidifier. In this case, dust flying in the indoor air accumulates and adheres around the nozzle of the humidifier. There is a problem going crazy.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a porous tile and far-infrared rays having a moisture-proof effect that can freely control the humidity of the indoor space in order to obtain the most suitable comfort for the human body in the living space. It is to provide a far infrared loess tile and a method of manufacturing the same that can maximize the radiation effect.

Far-infrared ocher tile using ocher according to the present invention to achieve the above object is characterized in that the porous body (body) manufacturing step, the surface glaze treatment step and firing step.

Hereinafter, the present invention will be described in detail for each process step.

A) porous body manufacturing

In order to free the absorption effect of the tiles, the body must be porous, so that 15 to 40% by weight of processed loess is mixed with 10 to 30% by weight of organic clay, which is a clay mineral having fine pores, and 20 for promoting sintering. 10-40 wt% of limestone and 10-15 wt% of limestone for imparting durability and adding body grinding raw materials and a small amount of sludge after primary firing of 5-10 wt% to promote absorption and porosity. After mixing, pulverizing and drying to form a mature body for 4 to 7 days to obtain a porous body.

B) Glaze manufacture

In order to show the aesthetic and absorbing effect of the tile surface, 15 to 40% by weight of processed loess emitting far infrared rays, 10 to 20% by weight of kaolin, and 15 to 50% by weight of frit are mixed. Wet ball mill grind to 350 mesh, add 0.2 to 0.8 wt% sodium dispersant for the efficiency of oil when applying glaze, and reduce plastic color change due to lot change of natural loess 3 to 10% by weight of zircon is added to obtain a glaze.

C) firing

In order to obtain a body that can exhibit a moisture-proof effect, since the interior should be porous, the firing temperature should be relatively low, and the firing temperature may be fired for 28 to 45 minutes between 1100 ° C. and 1150 ° C. in consideration of the melting temperature of the glaze on the surface.

After glazing the body fired under the above conditions, it is a process of calcining the second process prepared by firing at a temperature of 1030 ° C to 1070 ° C for 28 to 50 minutes.

In addition, in the case of the bottom ocher tile, the glaze is applied to the molded body (omitted by the first firing step), and the glaze and the body are fired once at a temperature of 1160 ° C. to 1190 ° C. for 40 to 60 minutes.

Here, the ocher used in the body manufacturing step and the glaze manufacturing step is a processed natural loess, which is heated for at least 30 minutes at a temperature of 300 ℃ to 800 ℃ to remove the adhered water or crystal water contained therein is used. .

EXAMPLE

The functional evaluation test of far-infrared ocher tiles according to the present invention was carried out as follows.

1) Deodorization rate test

In order to evaluate the ability to remove various odors by installing far-infrared ocher tiles on the floor and inside of the building, ammonia deodorization capability test was conducted using gas detection tube method.

Table 1 shows the deodorization rate change over time.

Changes in Gas Concentration and Deodorization Rate with Elapsed Time Item Early 30 minutes 60 minutes 90 minutes 100 minutes Sample 500 480 460 450 440 Ocher tile 500 190 150 130 98 Ocher tile deodorization rate (%) 60 67 71 78

As shown in Table 1, it can be seen that the deodorization rate increases as the loess is applied.

These results are known to be influenced by the pressure gradient of the gas, the difference in concentration, the osmotic effect, etc., but it is determined that the results are closely related to the pores formed in the loess structure of the raw materials.

These results are known to be influenced by the pressure gradient of the gas, the difference in concentration, the osmotic effect, etc., but it is considered that the results are closely related to the pores formed in the ocher structure in the glaze material.

2) Absorption Test

The water absorptivity was 16.48% for wall tiles and 3.85% for floor tiles when the blending ratio of loess was 30% by weight.

Absorption rate was 3.85% when the mixture ratio of loess was 30% by weight.

3) anti-mildew test

The fungal strains used in this test were collected as spores such as Aspergillus niger ATCC 9642, Peniclium pinophilum ATCC11797, Chaetomium globosum ATCC 6205, and used as mixed strains.

After 4 weeks, the antifungal test showed no mold habitat on the tile itself, and it was determined that the fungus was inhabited on the main surface of the specimen.

In fact, fungi are reported to prefer weak acidic growth conditions and slow growth rates, but ceramics such as ocher have a weak alkali, and antimicrobial metal ions dissociated from ceramics are also affected. It is estimated that the specimen used in the present invention is not a good condition for the growth of eukaryotes fungi, so it is determined that the fungus does not inhabit the specimens.

4) Far Infrared Radiation Intensity

4) Far-infrared radiation rate and radiation intensity

Almost all materials and objects were measured in the range of 5-20 μm.

The specimen was brought into close contact with the sample furnace and the specimen was heated to measure the far-infrared emissivity from the surface in the range of 5 to 20 μm.

At this time, the heating temperature used as the flooring material was measured based on the 35 ~ 40 ℃, the surface temperature of the measurement sample was maintained at 40 ℃, the surface temperature was fixed the same in preparation for the abnormal black body (copy ratio = 1).

On the other hand, although the radiation characteristic that some valleys are formed around 8-10 micrometers is shown, such a cause is estimated to be due to the component characteristic contained in a raw material component.

On the other hand, although the radiation characteristic of forming a slight valley around 8 ~ 10㎛ is shown, such a cause is estimated to be due to the component characteristics contained in the raw material shelf.

Among the characteristics of far-infrared radiant energy divergence, the black wavelength and the measured sample centered around 9.3㎛ by the Bin's Displacement Law.

In the case of ocher tile, the total radiation energy was 3.72 × 10 ² W / m ² .㎛ as shown in FIG.

5) Thermal effect measurement using thermography

Thermography is a method of displaying the skin surface temperature of the human body as a two-dimensional image, and when it is physically expressed, the energy distribution between far infrared rays (8-12 microns) is visualized.

The temperature of the human body was measured with a hot water boiler according to the combination of far-infrared ray radiator (bottom ocher tile), thermography was taken on the back of the human body, and the surface temperature of the floor was 37 ℃. Observation was made while rising.

In order to investigate the thermal effect of the human body on such far-infrared radiant body, the heating effect of ondol floor using ocher and existing cement ondol floor is heated from 37 ℃ to temperature distribution, Here, a comparative experiment was conducted using a Japanese Nippon Avionicos Corporation thermal bideo system (TVS-200MKII).

Figure 5 is a photograph of the back portion taken before lying on the bottom of the ocher tile, Figure 6 is a photograph taken after lying on the ocher floor tile ondol for 20 minutes under the same conditions as the cement ondol floor.

Figure 3 is a photograph of the back of a healthy man in his 30s before lying on the floor of cement ondol, Figure 4 is raised until the surface temperature of cement ondol until 37 ℃ after lying for 20 minutes while maintaining a constant temperature A picture taken of the site.

Figure 5 is a photograph of the back portion taken before lying on the bottom of the ocher tile, Figure 6 is a photograph taken after lying on the bottom of the ocher ondol for 20 minutes under the same conditions as the cement ondol floor.

Numerical analysis of the rejection of human thermal image due to the warming effect and the change of skin temperature before and after warming as heat storage and heat dissipation change rate showed that the ondol floor using ocher tile showed higher heat radiation to the skin than the cement ondol floor. It was.

As described above, the present invention can make the living space comfortable by manufacturing high functional porous tiles for indoor floors and walls, and can contribute greatly to health promotion by radiating far-infrared rays beneficial to the human body.

In addition, due to the structural characteristics of the ocher, it is possible to neutralize the toxic from the cement by manufacturing tiles with excellent humidity control and breathability.

In addition, when the far-infrared ocher tile according to the present invention is installed on the floor and the wall of the living space, it absorbs resonance with the human body by the effect of far-infrared resonance absorption, thereby promoting metabolism by activating cells and water molecules in the human body in the living space. It has the effect of improving the health of people living.
