Problems solved by technology

The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the ceramic patch has better performance than other metal materials. It is much superior. Ordinary ceramic sheets and rubber cannot be bonded together. After using glue, the bond is not firm, and the ceramic sheets need to be processed.

Abstract

A treatment process for alumina ceramic sheets, the steps are as follows: (1) Distilled water cleaning: wash and dry the ceramic sheets in 100% pure water; (2) Ketone washing: place the cleaned ceramic sheets in a 60‑70 % acetone soaking, drying; (3) alkali washing: the ketone washed ceramic sheet is placed in 80-90% sodium carbonate solution for soaking, drying; the beneficial effects of the present invention are: high hardness, excellent wear resistance , light weight, strong surface adsorption, which is 10‑20 of the surface adsorption of untreated ceramic sheets, and it is very firm and durable after being combined with glue and rubber.

Description

technical field [0001] The invention relates to the technical field of processing alumina ceramic sheets, in particular to a processing technology for alumina ceramic sheets. Background technique [0002] Alumina ceramics: High alumina content, relatively dense structure, and special properties, so they are called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of the octahedral gap, which is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point, high Hardness and excellent wear resistance. The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth and the friction coefficient is small, and the wear resistance is very ideal, especially in high-temperature oxidizing media or corrosive media, the performance of the ceramic patch material is better than that of other metal materials...
