AI Technical Summary

Problems solved by technology

However, the DLC and CrN coatings are prone to peeling off in the load environment, resulting in a decrease in the reliability of the compressor
[0005] Therefore, the performance of the sliding vanes of the compressor needs to be further improved.

Abstract

The invention provides a ceramic slip sheet and a preparation method and application thereof. The ceramic slip sheet comprises the following materials in percentage by weight: 70-99.6 % of Al2O3, 0-0.4% of MgO; 0-0.4 % of SiO2, 0-0.2% of CaO and 0-30% of nano ceramic. The ceramic slip sheet has higher rigidity, intensity and toughness and excellent wear resisting property.

Description

technical field [0001] The invention relates to the field of compressors, in particular, the invention relates to a ceramic sliding plate and a preparation method and application thereof. Background technique [0002] With the requirements of environmental protection, new refrigerants are needed to meet the requirements. At present, synthetic refrigerants CFC, HCFC and HFC are used more. CFC and HCFC refrigerants are gradually being phased out due to their damage to the ozone layer. Although the ODP value of HFC refrigerants is 0 , but the GWP value is still relatively high, which is a greenhouse gas that needs to be reduced. In Europe, it is advocated to replace natural refrigerants, such as the application of more and more CO 2 And R290, hydrocarbons are substances that exist in nature itself, have a good affinity with nature, will not destroy the balance of the ecological circle, zero ODP is extremely low, and the GWP value will not cause harm to the environment. CO 2 B...
