Three main factors that lead to high temperature grease loss

High temperature grease generally belongs to synthetic grease and contains high concentration of polytetrafluoroethylene lubricating particles. It has high temperature and pressure resistance and is suitable for high temperature heavy load equipment. This fluorine high temperature grease is specially used in high temperature, high load and chemical corrosion Bearings and components that require lifetime lubrication have good chemical inertness, durability and low volatility. Applicable temperature range: -50 to + 280 ° C.
1. The internal structure of the oil product is damaged:

High temperature grease is affected by heat and air in the friction lubrication area, and the base oil and thickener are oxidized, which causes the soap structure of the grease to be destroyed, resulting in softening and loss during use.
2. Impact of working load:

Due to the long-term operation of the friction part of the equipment, the high-temperature grease is constantly affected by shear stress, causing the soap structure to be damaged and softened and lost.
3. Factors of working environment:

Abrasion occurs in the moving bodies of mechanical equipment. Metal abrasive particles accelerate the oxidation of grease to produce organic acids, which destroys the grease structure and causes high-temperature grease to fail.
