Problems solved by technology

The disadvantages of this process are: ①The interstitial gas between the glass particles is difficult to be completely eliminated during the sintering process, and the porosity in the glass is high, and porosity defects are prone to appear after grinding and polishing, which affects the high-quality rate of the finished product; ②The sintering process requires strict control, even if Under the best sintering conditions, only 1.0-1.5mm thick dense layer can be obtained on the surface of glass-ceramic; brick deformation,

Abstract

The present invention discloses integral crystallization process of microcrystalline glass-ceramic composite brick and its production process. The brick includes microcrystalline glass layer and ceramic layer. The present invention features that by means of the available glass forming process, the microcrystalline glass is first produced into transparent glass mother board, then set on unglazed ceramic base and sintered in the roller kiln into semi-finished product through nucleation and crystallization of microcrystalline glass and the compounding with ceramic. The semi-finished product is strickled off, ground, polished, edge ground and sorted to form the microcrystalline glass-ceramic composite brick product. Compared with sintering process, the present invention has lowered cost, less faults and high product quality.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel integral crystallization glass-ceramic-ceramic composite wall and floor tile and a production method thereof. Background technique [0002] At present, there are two known active production technologies of glass-ceramics for architectural decoration, namely, the sintering method and the calendering method. Among them, the sintering method is the most widely used, and the technology is relatively mature. Now the glass-ceramic composite panels produced by ceramic manufacturers also use the sintering method. The calendering method is currently in the ascendant, and the formula and technology are not yet very mature, and only a few domestic enterprises are producing it. The production of glass-ceramic composite panels by calendering is still blank at present, and no manufacturers are producing them. As we all know, the production process of sintered glass-cerami...
