Description

Manufacturing method of multipurpose ceramic panel

The present invention relates to a method for producing a multipurpose porcelain panel. More specifically, the present invention relates to a method for producing a panel-type ceramics excellent in durability, heat resistance and aesthetics by greatly improving the use of conventional ceramics manufacturing process, such as shape manufacturing and firing conditions, significantly expanded its use.

'Ceramic ceramic panel' in the present invention is applied to improve the conventional pottery manufacturing process, the shape is a rectangular parallelepiped panel shape, refers to a product embodied a sculpture or a picture that can give an aesthetic appearance on the outside, which It is clearly distinguished from existing ceramics or other tile type products in terms of manufacturing process and shape.

Conventional ceramics have been used in real life, such as tableware, kettles and kitchen utensils or was limited to the porcelain for ornamental purposes, the manufacturing method also used the conventional method without a balance. In addition, even though ceramic materials are used as some building materials, they are mostly used for marble, tile bricks, tiles, and other blocks, and the color of the surface has been limited to colorless or single colors. 79-929; No. 81-297; 80-1706. In addition, the Republic of Korea Patent Publication No. 91-5024 discloses a ceramic material that is used by mixing a pattern of various natural stone shapes, but the process is very complicated and uneconomical, the produced product is less durable or heat-resistant, tile or brick It was to have limitation as use of building materials.

As is already well known, patterns or paintings of porcelain can be prepared by first baking the original porcelain, or by chaebol, then drawing the painting and applying glaze on it, or painting and baking on the glaze. , Shapes, patterns, drawings, etc. have been formed. In addition, the use of glaze, that is, different products are produced by the application amount, the firing temperature, as well as the manufactured ceramics also had problems in aesthetics and durability. For this reason, the traditional uses of celadon, white porcelain, etc., which are our own ceramics, have not been widely expanded, and their manufacturing methods have not been standardized.

The present inventors have diligently studied to eliminate the above-mentioned disadvantages, and as a result, by mixing the 65% by weight, 35% by weight of water and 0.03 to 0.05% by weight of sodium silicate, using a composition of the dough form thoroughly stirred and aged It was poured into a plaster mold (molding machine) engraved on the mold. After drawing a sketch on the surface of the molded product thus manufactured, it was raised to 800 to 900 ° C (hereinafter referred to as "primary firing temperature"), and maintained for about 9 hours. This painted surface was painted. After applying glaze to it and heating it again, the temperature is raised to a temperature of about 400 to 500 ° C. higher than the initial firing temperature (hereinafter referred to as “the original firing temperature”), and then maintained at the same temperature for at least 16 hours to obtain a finished product. It is done.

The above-described manufacturing method of the present invention is contrasted with raising the original firing temperature of 1,250 to 1,320 ° C and maintaining the firing temperature of 100 to 300 ° C lower than the conventional firing temperature, and the products of the present invention vary in size. Carved on one side of the panel form is a unique item that is clearly distinct from the form or use of conventional ceramics or tiles. Due to the characteristics of the present invention, it was found that the panel-like ceramics of the present invention have durability and heat resistance, and that the sculptures and pictures on the surface maintain the aesthetics and complete the present invention.

In the present invention, the term "sodium" means pulverized kaolin or similar minerals, dissolved in water, and then filtered. Kaolin is obtained by using kaolin minerals, clay, bentonite, etc. produced in Korea. have. As pigments, chromium oxide, manganese dioxide, manganese carbonate, cobalt oxide, nickel oxide, copper oxide, copper carbonate, uranium oxide (U ₃ O ₈ ), vanadium oxide, tungsten oxide, molybdenum oxide, silver nitrate, gold chloride, platinum, platinum chloride , A compound selected from aliphatic sugar (TiO ₂ ), antimony oxide, tin oxide, neodium, iridium, cerium, and the like may be used alone or in combination of two or more thereof according to a predetermined purpose.

Dough-like composition for producing the porcelain panel of the present invention can be prepared according to a known method, the raw material components are all available from nature or commercially available. After mixing the raw materials in the above-described range, and crushed for 7 to 10 hours at 80,000 to 120,000 rpm with a ball mill while adding an appropriate amount of water so that the particle size of the composition is 8.3μ or less. Since the composition of the present invention absorbs moisture into the gypsum rate (molding machine) with time on days of high humidity, it is preferable to inject in dry conditions.

Gypsum mold (molding machine) for producing a panel-type ceramics in the present invention is a form that can be detached in the form of four sides, one side of the panel to be manufactured in a state in which unevenness is applied to form a product of the present invention sculpture It is produced variously according to the size of the type ceramics.

In addition, the glaze is coated on the entire surface of the first pottery, once to several times 1 to 3mm, then put into the furnace and heated to the firing temperature of the bee. In the manufacturing method of the present invention, the holding time of the primitive and chaebol temperature is preferably 9 hours and 16 hours, respectively, and when it is shorter than this time, the creation of the pattern is not sufficiently developed, and sometimes when the firing is excessively long, the pattern is sometimes developed. This pattern may go away and appear in a single color. After this firing, ceramics with crystal patterns can be used as finished products, and can be finished. In addition, if the porcelain panel of the present invention employs a plaster mold (molding machine) engraved with the appropriate sculpture, the sculpture and specifications can be varied, as well as maximized aesthetics, so that its use is also infinitely versatile. .

Hereinafter, the present invention will be described through specific examples. However, it will be apparent that one of ordinary skill in the art according to the gist of the present invention belongs to the scope of the present invention.

Example 1

Soil, such as kaolin or its equivalent clay and bentonite, was pulverized and sufficiently dissolved in water, and then impurities were filtered out to prepare raw materials. Thus prepared material was mixed with about 0.03 to 0.05% by weight of sodium silicate to about 65% by weight, and then about 35% by weight of water was added, followed by stirring for about 5 hours using a stirrer. Then leave it for about two days to allow the dough to fully mature. Put this dough into a suitable four-side mold-type plaster mold (molding machine) according to the purpose, and then mold it, draw a sketch on the surface where the pieces are formed, raise it to 800 to 900 ℃, hold it for about 9 hours, The lights were turned off, allowed to cool completely, and then painted on a piece of electrical drawing or sketch. After applying glaze to it and heating it again, it heated up to 1,200-1,300 degreeC, hold | maintained for 16 hours or more at the same temperature, and then took out from the furnace and obtained the finished product.

As described above, the porcelain panel manufactured by the method for producing a panel-like ceramics of the present invention has a strong durability and heat resistance, as well as aesthetics, unlike the prior art, its use is used for walls, floors, doors, etc. In addition to building materials, as well as ornamental wall hangings, table pedestals, furniture attachments, etc. are endless, especially by making the molding machine in the form of gypsum, can eliminate the inconvenience of making by hand as in the conventional method, and also create And there is an advantage that can adjust the molding beauty of the crystal pattern to be expanded.
