How to choose phosphate grease with lubricity and advantages and disadvantages

Phosphate grease is a kind of vegetable grease with good combustion resistance and good wettability, and its air oxidation stability is more suitable, which is often loved by consumers. In addition, its thermal stability in China, ultra-low temperature is good, very good to use. But it also has a defect, that is, it will dissolve at high temperature. Phosphate ester will dissolve when it meets water. It is easy to produce effect on plastics, plastics, paints, coatings and lacquers. Some structures of phosphate ester also has a certain toxicity, which is the application of phosphate ester should pay attention to the problem.

There is a report below, listing the advantages and disadvantages of phosphate grease easy to watch:

Advantages of phosphate ester:

(1) the flame resistant;

(2) when containing retarder, it has better air oxidation stability;

(3) Good low temperature fluidity;

(4) High quality abrasion resistance and wear resistance, better friction characteristics;

(5) better radiation source stability;

(6) Degradable.

Defects of phosphate ester:

(1) Poor viscous-temperature characteristics;

(2) Poor stability of hydrolysis reaction;

(3) General corrosion resistance;

(4) only with very few rubber seals fork special vegetable grease soluble
