The ceramic coating sprayed on lithium battery powder equipment has the characteristics of wear resistance and corrosion resistance, easy monitoring of wear, high bonding strength, and convenient construction, as follows:
1. Excellent wear resistance: The ceramic coating has high hardness and strong wear resistance, which is 3-5 times longer than the service life of tungsten carbide coating. It can effectively resist the wear caused by material transportation, stirring and other operations during the operation of lithium battery powder equipment, reduce the degree of equipment wear, extend the service life of equipment, and reduce maintenance costs.
2. Prevention of metal foreign matter mixing: The coating composition does not contain metals, which can prevent the phenomenon of metal foreign matter mixing into lithium battery materials after equipment wear, meet the strict control requirements for metal foreign matter in positive electrode materials in lithium battery production, especially the control of PPB value for magnetic foreign matter, and ensure the safety performance of lithium batteries.
3. Easy to monitor wear: Some ceramic coatings use a unique dual color spraying process, with different colors for the base and surface layers. No detection methods are required, and the wear of the coating can be observed with the naked eye, making it convenient for users to monitor the wear status of the equipment in real time and perform maintenance and treatment in a timely manner.
4. High bonding strength: The ceramic coating has a high bonding strength with the equipment substrate, good toughness, strong impact resistance, and is not easily detached during equipment operation. It can reliably play a protective role and ensure the stability of the equipment under various working conditions.
5. Corrosion resistance and high temperature resistance: It has good corrosion resistance, can resist the erosion of some chemical substances in the production process of lithium batteries, and can also withstand high temperatures. It is suitable for various process equipment components and complex working conditions, and can maintain stable performance in a wide range of temperature and chemical environments.
6. Convenient and efficient construction: It can be repaired by partial spraying or on-site spraying operations, without the need to dismantle the equipment and return it to the factory, shortening the equipment maintenance cycle, improving production efficiency, and reducing the impact of equipment maintenance on production progress.
