The advantage of high-temperature grease is the thixotropy of grease-grease has the ability to flow when external force acts in a wide temperature range and stop flowing when external force disappears. The performance advantages include:
1. Long life
2. Excellent sealing performance;
3. The lubrication structure is simpler and more diverse
4. The use temperature range is wide, the use temperature can be lower than the lubricating oil, or far higher than the lubricating oil
5. Good viscosity, no loss, can still work normally after a long time of stopping, avoiding oil leakage.
According to the characteristics of grease and the harsh conditions of high temperature, high temperature grease has the following properties:
1. When the operating temperature is above 260 degrees, it does not lose and has thixotropy-it has the ability to bring the lubricating medium into the lubricating interface or maintain the lubricating medium
2. During high temperature use, Th will not cause reactions that are not conducive to lubrication (such as scorching, accumulation of carbon, etc.)
3. When the product is applied to high-temperature moving parts, the anti-friction performance of lubrication is not necessarily, and it must not cause serious wear to the lubricated parts. Detailed classification description of high temperature grease: Under the high temperature conditions used, high temperature grease should have the performance of not losing.
According to whether scorching or carbon deposition occurs during use, inferior products (scorching or carbon deposition occurs), general products (no scorching or carbon deposition, grease drying or residual lubricating medium), long-life products (no burning occurs) Small changes in coke or carbon deposits and grease). According to the lubrication performance in use, the products are divided into grease (high temperature bearing grease) and non-lubricating grease (high temperature sealing grease, high temperature bolt grease, etc.).
