JPH10265231A - Production of goishi, pai for mah-jongg and decorative plate by molding glass powder and sintering or fusing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To utilize the moldability, the colorability and the weldability of a glass powder. SOLUTION: A transparent glass and a colored glass are pulverized. After the transparent glass powder is mixed with a coloring agent, directly pressed and molded as it is or molded in a die by adding a binder, the pressed and molded one is sintered and the one molded by adding the binder is fused. Moreover, go stone for go, pie used for Mah-Jongg and a decorative plate are manufactured by applying a glaze containing the glass powder on the press-molded molding and by sintering or fusing. The producing methods are used as a decorative tray or a substitute for a product made of rock.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention uses glass powder,
Apply ceramic processing technology and mold it. A method for producing go stone, mahjong pie and decorative board by contacting the sintered bodies as they are or with each other.

[0002]

2. Description of the Related Art Go stones have been manufactured by roughly shaping fossils and rocks of shellfish and then polishing or shaping molten glass. For mahjong pie, use buffalo bone and process it to form it.
It has been manufactured by imprinting a pattern on the upper surface of this molded body. For decorative panels, rocks, fossils, colored glass or transparent glass are used, and small pieces obtained by cutting them are used as joints, adhesives or joints, or cut or polished from the above-mentioned raw materials. Was.

[0003]

[Problems to be Solved by the Invention] Go stones are processed from fossil rocks and shells, mahjong pies are processed from buffalo bones, and decorative boards are formed with various patterns. Although the products used adhesives, joints and metal fittings, these three types of processing required time and effort.

[0004]

Means for Solving the Problems In order to simplify and improve the efficiency of the manufacturing method, a method of forming and sintering or melting after forming by using a ceramic manufacturing method using glass powder is adopted.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In a go stone and a mahjong pie, a glass powder is molded and then directly sintered, or a molded body is also sintered with a wag sand. In a decorative board, glass powder is formed. The compacts are brought into contact with each other and sintered or melted.

[0006]

EXAMPLE For go stone, transparent glass or white glass is ground to 400 mesh or less. These powders were molded using a metal mold at a pressure of 10 kg / cm ² , and at 650 ° C., where a wag file containing glass powder was attached to the surface of the molded body, the temperature was 30 ° C.
Sinter for more than a minute. For lead glass, black go stones can be made at once without attaching the rags. For Mahjong pie, 10% of the volume of the glass powder was added to slaked lime to transparent glass powder crushed to 400 mesh or less.
It is molded using a mold at a pressure of kg / cm ² . A pattern made with glass powder-containing rags is placed on paper, and the paper is placed on the upper surface of the molded body, and this is sintered at 650 ° C. for 30 minutes or more to produce Mahjong pie. In the decorative board, the transparent glass is pulverized to 400 mesh or less. To this powder is separately added 10% of the glass powder volume by iron oxide and titanium oxide. In addition, lead glass powder is prepared. These powders are separately put into a metal mold and pressed under a pressure of 10 kg / cm ² . These compacts are brought into contact with each other and sintered at 650 ° C. for 30 minutes or more to produce decorative plates of three colors of red and black and white. Further, the transparent glass is pulverized to 400 mesh or less. 10% by volume of iron oxide and titanium oxide are separately added to this powder. In addition, lead glass powder is prepared. A binder is added to these three glass powders, and they are formed into a shape and pressed. After the compacts are brought into contact with each other, they are melted at 850 ° C. for 30 minutes or more to obtain a decorative board of three colors of red and black and white. Next, the green glass is pulverized to 400 mesh or less. A binder is added to the powder, and the powder is shaped and pressed into a shape. On the molded product, a black ragweed added with glass powder is placed on a paper and a figure is placed on the paper, and melted at 850 ° C. for 30 minutes or more to form a decorative board with a pattern.

[0007]

[Effect of the Invention] For go stone and mahjong pie, reuse of glass waste and simplification of the manufacturing method. For decorative panels, in addition to recycling glass waste, the glass moldings are brought into contact with each other, and then sintered or melted to produce large decorative panels at once, reducing manufacturing costs by simplifying the manufacturing method.

Claims (3)

[Claims] 1. A transparent glass powder and a mixed powder obtained by adding a white or black coloring agent to the powder are formed. In the case of a molded body of transparent glass, a go stone manufacturing method is performed by coating the surface of the molded body with rags and sintering the molded body. 2. A method for producing a Mahjong pie by adding a white colorant to a transparent glass powder and mixing, or separately forming a white glass powder, followed by attaching a patterned wag on its upper surface and sintering the same. 3. A colored glass powder or a mixed powder obtained by mixing a colorant with a transparent glass powder is formed. These compacts are brought into contact with each other, as they are, or by sintering the wag on the upper surface, or by contacting each other after molding a mixed powder obtained by mixing a coloring agent with a glass powder or a transparent glass powder,
A method of manufacturing a decorative board by wetting a rag on directly or in contact with it and then melting.
