PRODUCTION METHODS FOR ABRASION-RESISTANT GLASS-CERAMIC SHEETS WITH ROUGH SURFACE TEXTURE AND ABRASION-RESISTANT GLASS-CERAMIC SHEETS WITH ROUGH SURFACE TEXTURE

Abstract

The invention relates to the technical field of glass ceramics, and more specifically, to a method for producing wear-resistant glass ceramic plates with a rough surface texture and wear-resistant glass ceramic plates with a rough surface texture. The method of production according to the invention comprises the following steps: immersing the glass ceramic plate in an etching solution for high-temperature etching, and after the etching is completed, removing and cleaning the glass ceramic plate to obtain a wear-resistant glass ceramic plate with a rough surface texture; the etching solution is a molten mixture of an alkali and boron oxide, the alkali being one or more substances selected from the group including potassium hydroxide, sodium hydroxide, magnesium hydroxide, calcium hydroxide, calcium oxide, and zinc oxide, and the boron oxide content in the molten mixture is from 15 to 40% by weight; The arithmetic mean surface roughness of the wear-resistant glass-ceramic plate ranges from 2 to 6 μm, and the root-square slope ranges from 5 to 12°.The manufacturing method described in the invention can create a suitable arithmetic mean roughness and root-square slope on the surface of the glass-ceramic sheet, thereby significantly improving the abrasion resistance of the glass-ceramic sheet.
