Lightweight hygroscopic clay workpiece

The present invention relates to a lightweight hygroscopic clay processed material, and in particular, to a lightweight hygroscopic clay processed material which is excellent in hygroscopicity and breathability and can be used as a hard stone, stone stone and building materials.

Busy modern people who live in concrete walls have a very limited opportunity to come in contact with nature, so they are striving to approach nature through various hobbies. One of the methods is to make small flower beds, artificial ponds, By artificially decorating stone carvings, they have the opportunity to be emotionally friendly with nature. Stone stone crops that grow plants, such as eggs, have been selected from natural stones, which have a unique shape that can give an aesthetic sense. Therefore, stone stone stones of the desired shape could not be obtained and natural stone has low porosity that can retain moisture. Because of this, there are significant problems in the conditions under which plants can survive, especially in the supply of moisture.

On the other hand, the bricks used in the past are fired by clay or cement, and thus, when used in a house, the ventilation is not good, so it is not possible to create a pleasant environment. Moreover, the cement block has a harmful effect on the human body due to the toxicity of cement. do. In addition, such a conventional brick is heavy and requires a lot of cost and labor in transportation and work.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to provide a lightweight hygroscopic clay processed material containing a light weight, excellent hygroscopicity and breathability, and inorganic.

In order to achieve the above object, the first embodiment of the lightweight hygroscopic clay processing material of the present invention is kneading a mixture of 50% by volume of clay, 20% by volume of charcoal, 30% by volume of sawdust in water of a size of 2-15mm in diameter It was formed into a ball shape and characterized in that it was fired at 1100 ℃-1300 ℃.

The second embodiment of the lightweight hygroscopic clay processing material of the present invention is characterized by kneading a mixture of 80% by volume of clay and 20% by volume of sawdust in water to form a potted or shaped landscape stone and firing it at 1300 ° C.

The third embodiment of the light-weight hygroscopic clay processed material of the present invention is characterized in that a small amount of natural fragrance is added to a mixture of 50% by volume of clay and 50% by volume of sawdust and kneaded in water to pressurize and mold the clay brick with a predetermined size.

Hereinafter, preferred embodiments of the present invention will be described in detail.

<First Embodiment>

The first embodiment of the present invention relates to a light-weight hygroscopic clay processing material that can be used as a hard stone, the raw material of the present embodiment is prepared by kneading water in a mixture of clay 50 vol%, charcoal 20 vol%, sawdust 30 vol%. Clay is formed by the weathering of igneous rocks at the surface, and various components of clay are produced according to the type, decomposition and metamorphic process of the mother rock. In other words, clay is a secondary product produced in the earth's crust due to natural decomposition such as feldspar and mica, which are weathered and hydrothermal. Such clays exhibit plasticity when containing moisture as aggregates of natural fine particles, and exhibit rigidity when dried, and sinter when fired at an appropriate temperature. The component is alumina silicate and the chemical formula is Al ₂ O ₃ · 2SiO ₂ · 2H ₂ O. However, these formulas are rarely used. This is because clay is a fine particle produced by the decomposition of rock or mineral as described above, and thus contains various impurities. For example, clay produced in Michang-ri, Seochang-myeon, Minnam-gun, Jeonnam consists of 65.10% SiO ₂ , 14.4% Al2O3, 2.14% Fe2O3, 0.8% CaO, 0.27% MgO Is composed of 63.46% SiO 2, 24.60% Al 2 O 3, 1.88% Fe 2 O 3, 0.98% CaO, 1.11% MgO. Kaolin is also called kaolin, and its chemical formula is Al ₂ O ₃ · 2SiO ₂ · 2H ₂ O, which is different from clay in terms of chemical composition, but in physical properties. In general, the firing color is white or pale color close to white.

Sawdust is burned during firing to generate pores, so that the ovary after firing has many pores, and ash produced by burning sawdust becomes fertilizer to help the roots of eggs grow. Charcoal lowers the specific gravity of the turbulence and increases the hygroscopicity, and remains as an inorganic mineral of the solid component after firing, thereby supplying fertilizer to the eggs for a long time. The raw material of the mixture should be molded to a size of about 2-15 mm in diameter, and the molding can be made by hand, and is preferably mechanically mass-molded by an extruder. The molded mixture is molded in a kiln, the forming temperature is adjusted according to the desired color. For example, white calcite is desired at 1100 ° C, pink at 1000 ° C, and scarlet at 1270 ° C. The firing time depends on the amount of raw materials, preferably about 6-7 hours when the raw material is 0.5 rube.

<Second Embodiment>

The second embodiment of the present invention relates to a lightweight hygroscopic clay processing material capable of producing stone crushed stone attached to an egg or ornamental plant, wherein the raw material of this embodiment kneads water to a mixture of 80% by volume of clay and 20% by volume of sawdust. It is. This raw material mixture is molded into a predetermined shape, for example, the shape of Mt. Seorak, and then fired at about 1300 ° C. in a firing furnace to be completed as stone crushed stone. Such stone crushed stone has a large number of pores due to the sawdust burned during firing to increase the hygroscopicity and water retention, as well as contains a large number of minerals and other minerals due to the burned sawdust to promote root ignition of the stone plant. .

<Third Embodiment>

The third embodiment of the present invention relates to a lightweight hygroscopic clay processing material that can be used as a brick, the raw material of the present embodiment is a medicine that can discharge natural flavor in a mixture of 50% by volume of clay, 50% by volume of sawdust. After adding a small amount of kneading in water. Since the present embodiment is intended to be used as a brick, by molding into a rectangular parallelepiped of a predetermined brick size and then dried by a forced drying method in a natural drying or drying furnace is completed without a separate firing process. The usual manpower or press-molding method is adopted for brick molding.

Hereinafter, the effect of the lightweight hygroscopic clay processed material of this invention of the said structure is demonstrated.

According to the first embodiment of the present invention, by heating the raw material containing the sawdust and char of a predetermined shape at high temperature to produce a turbulence, not only a large amount of pores are generated by the burned sawdust but also solid char remains It lowers the specific gravity of and makes the hygroscopicity and water retention very good. In addition, the pores present in the ovaries facilitate the supply of oxygen to the roots of the eggs. In addition, mineral fertilizers, such as minerals contained in the burned sawdust and charcoal to help the roots of the roots to increase the sticking speed. In addition, the raw materials used in the present embodiment can all be easily obtained from the surroundings, and because the material cost is also cheap and the manufacturing process is simple, it is possible to manufacture a cheap ovary.

According to the second embodiment of the present invention, since the mixture of clay and sawdust is calcined at high temperature to prepare stone crushed stone, a large amount of pores due to burning of sawdust exists in the stone crushed stone. Therefore, because the pores can contain a large amount of water, it is easy to manage the stone crops, and even when the house is left for a long time, the moisture is retained in the stone stones so that expensive ornamental plants are not dried and killed. In addition, by varying the shape of the desired shape by firing the stone stone stone, various changes are possible for ornamental use, which can produce a much more beautiful bird's-eye view than the conventional natural stone.

According to the clay brick of the third embodiment of the present invention, it can be used as an environmentally friendly building material because it is superior in breathability and moisture retention compared to conventional plastic bricks or cement blocks. Compared with cement blocks and ocher bricks, it is light in weight and has a convenient construction.
