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 aluminum oxide ceramic sheet processing technology. The aluminum oxide ceramic sheet processing technology comprises the following steps: (1) washing with distilled water: washing the ceramic sheet in 100% pure water, and drying; (2) washing with acetone: immersing the washed ceramic sheet in 50% to 60% acetone, and drying; and (3) washing with alkali: immersing the ceramic sheet washed with the acetone in 60% to 70% sodium carbonate solution, and drying. The aluminum oxide ceramic sheet processing technology has the beneficial effects that the hardness is high, the abrasion resistance is extremely good, the weight is light, the surface adsorption capacity is high and is 10 to 20 of that of the ceramic sheet which is not processed, and the aluminum oxide ceramic sheet is firm and durable after being bonded to rubber by virtue of 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. 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...
