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 discloses an aluminum oxide ceramic chip treatment technology. The technology comprises the following steps of 1, distilled water washing, wherein a ceramic chip is placed in 100% pure water to be cleaned and then dried; 2, acetone washing, wherein the cleaned ceramic chip is placed in 40-50% acetone to be soaked and then dried; 3, alkali washing, wherein the ceramic chip washed with the acetone is placed in a 80-90% sodium carbonate solution to be soaked and then dried. The aluminum oxide ceramic chip treatment technology has the advantages that the ceramic chip is high in hardness, excellent in wear resistance, low in weight and high in surface adsorption capacity which is 10-20 times that of an untreated ceramic chip, and is quite firm and durable after being combined with rubber through glue.

Description

technical field [0001] The invention relates to the technical field of processing alumina ceramic sheets, in particular to a processing technology for alumina ceramic sheets. Background technique [0002] Alumina ceramics: High alumina content, relatively dense structure, and special properties, so they are called special ceramics. Al 2 O 3 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, which is the same stable α-Al as natural corundum. 2 O 3 Therefore, the ceramic has a 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 and the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the performance of the ceramic patch material is better than that of other met...
