Description

Yellow soil and it`s manufacturing method

The present invention relates to an ocher plate and a method for manufacturing the same, and more particularly, to fire the ocher in a plate form for use as a building flooring plate and an internal and external plate, so as to increase the ocher and clay to 85% by weight so that far infrared rays are radiated in large quantities. The present invention relates to an ocher plate and a method of manufacturing the same, in which the surface strength is increased so that the surface can be polished and polished to have a marble texture.

In general, ocher prevents the infestation of various fungi harmful to the human body, and has a function of absorbing strong alkaline components, which are harmful to the human body, and neutralizing lipid peroxide. Ocher has an excellent effect of releasing far-infrared rays which purify the surrounding environment while living and breathing beneficial microorganisms, promoting blood circulation and metabolism of the human body, activating cellular functions and promoting growth.

Most of the building materials using the loess are provided in the form of bricks, and Korean Patent No. 421698 discloses a method of manufacturing loess bricks. Conventional ocher bricks were made by mixing bricks with ocher and reward soils to make bricks with a vacuum injection molding machine and then baking them in a kiln after drying. However, the conventional ocher brick has a disadvantage in that it cannot be used as a building plate because it is in the form of a block for masonry on the outer wall.

In view of this, Patent No. 426777 discloses ocher bioboards. It comprises 45-50% by weight of dehumidified ocher, preferably 47% by weight, 35-45% by weight of ferrite, preferably 40% by weight, 8-12% by weight of gypsum, preferably 10% by weight. The mixture is mixed with 3% by weight of natural orange sap as a natural curing agent to the mixture of ocher, perlite and anhydrous gypsum, and then calcined in the form of a board.

However, the conventional ocher bioboard is produced less than 50% by weight of ocher in order to increase the overall strength, so there is little generation of far-infrared rays, and there is a limit to its use because there is no natural pattern such as marble on the surface.

The present invention was developed in view of the conventional problems, the object of the present invention is to fire the loess into a plate for use as a building flooring plate and interior and exterior plates, but the amount of far infrared rays is increased by increasing the specific gravity of the loess and clay to 85% by weight. To prevent the shrinkage deformation during firing by adding boiled earth, silica sand and martha, and to increase the surface strength, it is possible to be polished. Polishing and polishing to provide an ocher plate having a marble texture and a method of manufacturing the same.

To this end, the present invention is uniformly mixed with 50% by weight of ocher, 35% by weight of clay, 10% by weight of clay, 2% by weight of silica sand and 3% by weight of sanda to make a plate and plastically combine it in a kiln and then measure the width and length. It is characterized by cutting to fit and polishing and polishing the surface.

According to the present invention, since the clay contains 85% by weight of clay, which enhances the bonding force while having ocher and ocher components, when the ocher plate is made by firing, a large amount of far infrared rays are emitted.

Particularly, when the ocher is formed into a plate, the retaining soil to prevent shrinkage is added, and the silica sand to express the cross-sectional shape according to the surface polishing is added while the surface strength is increased to enable polishing, and the masa to control the moisture is added. Cracks and distortions are prevented during drying and firing of the sheet so that ocher can be formed into a sheet having a desired shape and size.

In addition, it is not necessary to have a high-capacity press because the ocher dough from the vacuum compression molding machine is pressed into a sheet by pressing a press of 80 to 150 kg / ㎠, and the molded sheet is dried at a temperature of 20 to 40 degrees for about 40 hours at low temperature. It does not require a lot of dry calories because it prevents cracking. Since the dried plate is heated in three stages of first and second preheating and firing, the structure is dense and stabilized, thereby preventing the plate from twisting.

And when sprinkling the additives on the surface of the ocher plate in the molding process and pressing them with a press, the additives are embedded in the surface and then fired. After that, various types of patterns are displayed on the surface of the ocher plate by surface polishing and polishing. Because it can express the effect of reducing the use of expensive marble is effective.

The ocher plate of an embodiment of the present invention is 50% by weight ocher, 35% by weight clay is used, 10% by weight of boreum clay, 2% by weight of silica sand and 3% by weight of yarn. As the clay has an ocher component, the ocher plate of the present invention has a very high far-infrared emissivity as shown in the following table because the far-infrared emissivity is the same as that of ocher while having a viscosity that enhances the binding force of the ocher.

Korea Institute of Construction Materials R081128-FW004 (Dec. 2008)

According to the test results, the emissivity was higher than that of charcoal, elvan, and ceramic powder 0.927 (5 to 20 µm).

The retaining soil serves to prevent the shrinkage of the plate during the firing process, and the silica sand has a function of increasing the surface strength to be polished, and when the surface of the plate is polished and polished after firing, irregular polishing cross sections are formed on the surface. This allows the surface of the plate to be expressed in various ways. To this end, the silica sand is pulverized into particles 10mm or more and mixed with ocher and clay, and when the calcined plate is polished, irregularly distributed silica sand grains are polished together with the plate to exhibit an irregular cross section. And the massage function to control the moisture in the drying process.

The manufacturing process of the present invention is as follows.

First, the clay and clay, which are the main components of the present invention, are mixed and added to the clay, silica and masa, so that the water content is 15% or less, and the mixture is uniformly distributed at a pressure of 600 mm / hg or more in a vacuum compression molding machine. After bubbles are completely removed, they are continuously extruded into a plate and cut into a plate of a required size.

Subsequently, the cut plates are pressed at a pressure of 80 to 150㎏ / ㎠ in a press forming machine to make the tissue dense. Before pressing, the plate surface is sprayed with additives having colored glass powder or colored stone powder on the surface of the plate. You can get stuck. When the additives are sprayed as described above, these additives are polished together when the surface is polished after firing, and are arranged on the surface of the plate while having various shapes of cross-sections to improve design.

 After the press work, the boards are dried for about 40 hours at a temperature of 20-40 ℃ and a humidity of 70% or less. Since the ocher plate of the present invention has a size of 300mm × 300mm × 20mm or more, low-temperature drying is performed because it cannot be easily cracked and twisted when molded at high temperature.

The dried board is plastically bonded in a kiln. Since the ocher plate of the present invention has a large area, it is necessary to preheat it by dividing into 1st and 2nd to prevent cracking and to stabilize the structure. The primary preheat is preheated for about 10 to 12 hours until it reaches 600 ° C, and the secondary preheat is preheated for about 12 to 14 hours until it reaches 600 to 1000 ° C. And finally it is heated for about 10 to 12 hours until it reaches 1000 to 1200 ℃ for plastic bonding.

After the calcination is completed, the ocher plate may be selectively subjected to a fading operation (blackening) to blacken the surface. Plates that have not undergone color fading have an inherent color, while plates that have been faded are made of black ocher. This immersion is carried out by mixing oil and water at about 2: 1 and then feeding the kiln, where hydrocarbon gas is deposited on the sheet. The bleaching operation is repeated 3 to 4 times for 1 to 2 hours. Hydrocarbon gas is explosively diffused in the kiln at a temperature of 800 ° C. or lower in slow cooling, and evenly discolors the plate.

After firing, the kiln door is opened slightly when the kiln temperature reaches 550∼600 ℃ and slowly cooled. Afterwards, when the kiln temperature reaches 250 ℃, the door is completely opened and quenched.

After the firing and cooling in the kiln is completed, the burned ocher plate is taken out, cut into horizontal and vertical saw blades according to the specifications, and the surface is polished and polished to give a marble-like texture.

Polished and polished ocher boards are used as interior materials to provide photocatalytic coatings for sterilization and waterproofing. When used as exterior materials, surface water repellents are used to prevent dust from sticking and run down when it rains.
