Production method of freehand microcrystalline glass board

Abstract

The invention relates to a production method of a freehand microcrystalline glass board. The production method comprises the following steps of respectively preparing seven microcrystalline glass aggregates with different colors, getting the microcrystalline glass aggregates with any two or more colors and uniformly scattering the microcrystalline glass aggregates with different colors in a stainless steel mould frame with a textured grating in sequence; moving a glass gate board at the bottom of the stainless steel mould frame for dropping the microcrystalline glass aggregates into a fireproof mould sprayed with an aluminum oxide sizing agent which is 1mm thick, and the fireproof mould carrying the microcrystalline glass aggregates enters a roller kiln; preheating, fusing the aggregates, crystallizing and preserving the heat at 1100 DEG C-1150 DEG C, cooling and discharging out of the kiln for firing a freehand microcrystalline glass board crude product with whole-body textures; and carrying out surface coarse-grinding, fine-grinding and polishing to obtain a freehand microcrystalline glass board finished product with clear texture patterns and board glossiness of over 90 degrees. The freehand microcrystalline glass board prepared by the production method disclosed by the invention has abundant colors, line textures from the inside to the outside, and physical and chemical performances better than those of a stone.

Description

technical field

[0001] The invention relates to a production method of a freehand glass-ceramic plate. Background technique

[0002] Glass-ceramic is a kind of glass with a specific composition. It is a polycrystalline material obtained by controlled crystallization. It has high strength and good weather resistance. It can be used as a building decoration material to replace high-grade stone.

[0003] At present, the design and color varieties of glass-ceramic plate products are mainly single color, which cannot reach the rich and colorful decorative effect of natural stone. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for producing freehand glass-ceramic plates. The freehand glass-ceramic plates prepared by the present invention have rich colors, lines and textures from the surface to the inside, and have better physical and chemical properties than stone materials.
