Description

Red clay tile and its manufacturing method {Red Clay Tile and Manufacturing Method Thereof}

The object of the present invention is based on loess, and if necessary, sand (silica or quartz) is added thereto, molded by adding water, dried and fired at high temperature without glazing, thereby preventing slippage and far infrared rays. It has a function of activating metabolism due to release, as well as preventing athlete's foot, thus providing a highly functional tile. In addition, it has the natural color of yellow clay, which is visually friendly to nature, and can be used as interior and exterior materials of buildings, and it can contribute to the health of the human body by not only saving energy but also emitting far infrared rays by releasing the heated heat for a long time for a long time. In addition, it is possible to develop products that meet the social needs of high quality products and high functional products.

Another object of the present invention is to provide a method for producing a high functional ocher tile by using such loess as a main material and adding sand (silica or quartz) to it, forming water, drying and glazing at high temperature without glazing. .

Existing general tiles are added with chemicals or thickeners at the raw material stage, and the glaze is coated and sintered on the surface so that all the pores are blocked, which can act as a cause of athlete's foot due to no slippery and aeration effect due to moisture. However, because the surface is smooth and can slide, it can fall or cause fractures and cause cerebral hemorrhage. Until now, research on high functional tiles has been actively conducted, but tiles as a building material manufactured by adding loess to loess as a main material have not been developed.

As a result of long researches on the manufacture of the tiles, the present inventors have found that when the tiles are manufactured by adding sand (silica or quartz), shaping and hot baking only, if necessary, to maintain the high strength of the tiles, It can have the ventilation effect on the back side, and can produce tiles that meet the social requirements for high performance and high quality.

Accordingly, the present invention provides ocher tiles produced by hot baking without adding glaze (silicite or quartz) to it and, if necessary, by adding sand (silica or quartz).

Another object of the present invention is to provide a method for producing ocher tile by using loess as a main material and, if necessary, adding sand (silica or quartz) to it and baking at high temperature without glazing.

For the manufacture of high-performance ocher tiles such as anti-slip and athlete's foot and far-infrared emission, ocher and sand (silicone, quartz) are used as raw materials for loess alone or in loess (silica and / or quartz) Up to 40% by weight and the raw material is ground to a particle size of 100 or less by a mill. In the case of the ocher particles obtained in the particle size range of 100 throat or less, the touch is soft and prevents slipping due to the atomization of the particles.

The raw material obtained in the fine granules is kept by the dehydrator (vibrator) and the filter press so that the raw material contains only a proper ratio of moisture, and all the air present in the substrate is degassed by repeating the refining machine 2 to 5 times. . The completely degassed body is pressed by a roller machine to obtain a tiled body. After drying for 10 to 48 hours in the shade on the molded tile-like base material, the shape of the tile is completed with a shaper. The finished tile is heat-treated for about 20 minutes to 5 hours at the initial temperature of 800 ± 20 ° C. After the calcined body is cooled to room temperature, it is again maintained at the final temperature for about 3 to 15 hours in the conglomerate temperature range of 1180 ± 30 ° C to prepare the loess tile maintaining the crack and strength.

In the case of yellow soil, the composition ratio of the soil is somewhat different, but the main components of silica (SiO ₂ 40 ~ 60wt%), alumina (Al ₂ O ₃ 20-30wt%), iron oxide (Fe ₂ O ₃ 9-12wt%) In addition, Feldspar of MnO, K ₂ O, Na ₂ O and CaO occupy the rest. Usually, feldspar has different feldspars (K ₂ O.Al ₂ O ₃ .6SiO ₂ ), soda feldspar (Na ₂ O.Al ₂ O ₃ .6SiO ₂ ) and limestone (CaO.Al ₂ O ₃ . 6SiO ₂ ) and the like.

As such, ocher is composed mainly of alkali metals and alkaline earth metals, in addition to SiO ₂ , Al ₂ O ₃ and Fe ₂ O _3, which are the main components of all soils. When heated, it is a material having the ability to emit far infrared rays, which are long-wave at low temperatures. In addition, the crystallization components can maintain the high strength even at low temperature conglomerate roasting chaebol vitrification of the components by vitrifying the body even at a low temperature of 100 ~ 200 ° C relatively. In particular, feldspars emit a large amount of low-temperature far-infrared rays, which are beneficial to the human body for the heat absorbed during heating, thereby enabling the role of high-functional tiles. In general, infrared rays are divided into 0.76 to 1,000 μm, which is longer than visible light, and are divided into 0.76 to 4.0 μm near infrared, 4.0 to 50 μm mid-infrared, and 50 to 1,000 μm far-infrared. Far-infrared rays are known to facilitate physiological effects when they act on the human body because of the same wavelength as water, the main component of the human body.

The ocher tile of the present invention can be spotlighted as an interior and exterior material of a building, and it is judged that it can be used in businesses such as a jjimjilbang or an ocher room. In particular, various products such as ocher paints and pigments, ocher-added floor coverings, wallpaper, and even underwear or shoes are introduced, but all of them are mainly functional products by ocher addition. However, this product of the present invention, the main component of the loess and the small amount of sand is added only because the raw material is manufactured and manufactured can be utilized to maximize the functionality due to loess. In addition, paints, pigments, such as ocher paint, and ocher are applied to the building by repeated application, which causes cracking, torsion, and cracking after drying, and thus the necessity of maintenance and repair. As a result, the aesthetics of the building will cause considerable inhibition. However, in the case of this ocher tile, only the tile which is finally prevented from cracking is manufactured and shipped through a series of processes using ocher, so it is the same as the existing tile in terms of construction, maintenance and maintenance, and incurs no maintenance or repair costs. It does not have the advantage. It is a product that emphasizes the convenience of construction, maintenance and management as well as the high functionality of ocher tile.It will be a functional product that can enhance the culture of human life by fulfilling its role as a product with both aesthetic and functional aspects of buildings. It is expected.
