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 a treatment process for an aluminum oxide ceramic chip. The treatment process comprises the following step one of distilled water washing, wherein the ceramic chip is placed into 100% pure water to be washed and dried; the step two of acetone washing, wherein the washed ceramic chip is placed into acetone with the concentration being 20-30% to be soaked and dried; the step three of alkaline washing, wherein the ceramic chip subjected to acetone washing is placed into a sodium carbonate solution with the concentration being 90-100% to be soaked and dried. The treatment process has the advantages that hardness is high, a wear-resisting property is excellent, the weight is low, surface adsorption force is large and is 10-20 times that of an untreated ceramic chip, and after being combined with rubber through glue, the ceramic chip is extremely firm and durable.

Description

Technical field [0001] The invention relates to the technical field of alumina ceramic sheet processing, in particular to an alumina ceramic sheet processing technology. 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 gap. This is the same stable α-Al2O3 structure as natural corundum, so ceramics have a high melting point and 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 the high temperature oxidizing medium or corrosive medium, the ceramic patch material has better performance than other metal materials. It is much more supe...
