Polishing glass facing brick and manufacturing method thereof

Abstract

The invention relates to a polishing glass facing brick product and a manufacturing process thereof. A substrate of the polishing glass facing brick consists of the following components: 59 to 80 percent of porcelain sand, 15 to 40 percent of black mud and white mud and 0.5 to 5 percent of additive. A glass melting material consists of the following components: 5 to 20 percent of barium carbonate, 20 to 40 percent of aedelforsite, 10 to 40 percent of albite, 20 to 30 percent of kaolin, 3 to 10 percent of zinc oxide and 8 to 10 percent of talc. The glass facing layer consists of the following components: 20 to 80 percent of the glass melting material and 15 to 90 percent of crude materials. The method for manufacturing the polishing glass facing brick comprises the following steps: formingthe substrate of the polishing glass facing brick, and preparing a glass granular material and glass facing layer slurry; carrying out color decoration on the substrate of the glass facing brick; wetly dressing a glass layer; carrying out calcination on the polishing glass facing brick; polishing the glass facing brick product out of a kiln on a profiling soft polishing machine; and manufacturingthe polishing glass facing brick product.

Description

technical field [0001] The invention relates to a polished glass facing brick product and a manufacturing process thereof. Background technique [0002] CN00130117.9 discloses a "glass-ceramic composite plate and its production method", its purpose is to provide a glass-ceramic composite plate and its production method, which uses the glass-ceramic frit produced by conventional techniques, The frit of the glass-ceramics is evenly distributed on a bisque-fired ceramic substrate whose expansion coefficient is basically the same as that of the glass-ceramics, and is placed in a kiln for firing. Another purpose is to provide a glass-ceramic composite plate prepared by the above-mentioned production method. Its technical composition: the glass-ceramic composite plate is composed of a glass-ceramic layer on the upper side and a ceramic substrate on the lower side. The production method for making a glass-ceramic composite plate comprises the following steps: (1) preparing a glas...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the pressed ceramic substrate needs to be first sintered into a green body, and then the glass-ceramic frit particles are evenly distributed on the substrate on the green body, and the second firing is carried out in a roller kiln to make it a green body. Composite board; the disadvantage is that the surface layer and edges of the glass frit particles of the dry cloth on the green body are uneven, and after leaving the kiln, a large amount of trimming, scraping, grinding and polishing must be performed on the surface of the composite board; The amount of cutting is large, the waste of raw materials is large, and the energy consumption is high

The above-mentioned invention divides the prepared ceramic powder and glass slag into secondary distribution and press molding; its shortcoming is that the compression ratio of the ceramic powder layer is different from that of the pre-melted glass layer, and it needs to be polished to cover the surface. If the bottom blank is not leaked in the end, a large amount of mixture of surface ceramic powder and glass slag is required, and the amount of surface mixture is large and the cost is high; at the same time, the glass slag is in contact with the film of the mold during pressing and molding, and the mold is easily damaged; After finishing, it also needs to be scraped, ground and polished. The cutting volume is large, the waste of raw materials is large, and the energy consumption is high.

[0004] The shortcoming of the above two inventions is also that the variation of the decorative pattern on the surface is only the collocation of different colored glass granules or extremely simple patterns, and the entire surface color or pattern is single.
