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

The invention provides an alumina ceramic wafer treatment process. The process comprises the following steps: (1) cleaning with distilled water: putting a ceramic wafer in 100% pure water to be cleaned and drying the ceramic wafer; (2) cleaning with acetone: putting the cleaned ceramic wafer in 10-20% acetone to be soaked and drying the ceramic wafer; (3) cleaning with alkali: putting the ceramic wafer cleaned with acetone in a 70-80% sodium carbonate solution to be soaked and drying the ceramic wafer. The process has the beneficial effects that the ceramic wafer has high hardness, excellent wear resistance, light weight and strong surface adsorbability which is 10-20 times that of untreated ceramic wafers; the ceramic wafer is very firm and durable after being bonded with rubber via 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 are filled in 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, 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...
