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 40‑50 % acetone and dried; (3) Alkaline cleaning: Soak the ketone-washed ceramic sheet in 90-100% sodium carbonate solution and dry; (4) Pickling: Dry the ceramic sheet in step (3) The ceramic sheet is soaked in 10% sulfuric acid solution and dried; the beneficial effects of the present invention are: high hardness, excellent wear resistance, light weight, strong surface adsorption force, which is the highest surface adsorption force of untreated ceramic sheet 10‑20, very strong and durable after being combined with rubber by glue.

Description

technical field [0001] The invention relates to the technical field of alumina ceramic sheet processing, in particular to an alumina ceramic sheet processing process. Background technique [0002] Alumina ceramics: high alumina content, relatively dense structure, and special properties, so it is called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions fill two-thirds of the octahedral gaps. This is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high Hardness, with excellent wear resistance. 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 super...
