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 relates to an alumina ceramic wafer treatment technique which comprises the following steps: (1) distilled water washing: washing a ceramic wafer in 100% pure water, and drying; (2) ketone washing: immersing the cleaned ceramic wafer in 40-50% acetone, and drying; and (3) alkali washing: immersing the ceramic wafer subjected to ketone washing in a 60-70% sodium carbonate solution, and drying. The alumina ceramic wafer treated by the technique has the advantages of high hardness, excellent wear resistance, light weight and high surface adsorptivity (the surface adsorptivity is 10-20 times of that of the untreated ceramic wafer), and is very firm and durable after being combined with glue and rubber.

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. Al 2 o 3 The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions fill two-thirds of the octahedral gaps, which is the same stable α-Al as natural corundum. 2 o 3 Structure, so ceramics have 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, 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 sup...
