In which fields can perfluorinated polyether greases be used? What do you need to pay attention to when using?

Perfluorinated polyether grease is a kind of advanced lubricant with excellent high temperature resistance and chemical resistance, which can be used for lubrication protection under harsh conditions such as high temperature, high speed and fluctuating load. It can be used in the aerospace field, automotive parts, and can also be used as a long-life lubricating material in many lubrication points.

First, in the chemical industry

Perfluoropolyether oil is used as an industrial fluid in various vacuum pumps (including rotary pumps, turbolecular pumps and steam diffusion pumps), and is used as a lubricant for compressors and valves when corrosive gases are present in the operating environment.

Second, in the electronics industry

The use of plasma etching, LPCVD and plasma cultivation technology to produce semiconductors requires the use of some vacuum mechanical pumps, and the use of perfluorinated polyether oil as vacuum pump oil also has a very good lubrication effect!

Again, in the machinery industry

Perfluoropolyeth oil is often used as high-temperature and chemically stable porous metal bearings, conveyor belts, paper and textile machinery lubricating oil, when used as plastic bearing lubricating oil, its wear resistance is greatly improved, when some electromechanical equipment (such as current contactors, switch buttons and sliding electric contactors, etc.) in the need for good lubrication and arc resistance is often used perfluoropolyeth lubricating oil.

Finally, in the magnetic media industry

Perfluoropolyether oil has low friction coefficient, low volatility and good insulation, and can be used as the lubrication of hard disk, tape and other magnetic recording media on computer, video, automatic recording device and other instruments.

Perfluorinated polyether grease needs to pay attention to the following points:

(1) Whether the material is compatible: perfluorinated polyether grease may have adverse effects on the surface of some specific materials, such as corrosion of some plastic materials, so it is necessary to do a good job of testing and testing before use to avoid unpredictable consequences.

(2) Avoid mixing of grease: perfluoroether grease and other types of grease can not be mixed, otherwise it will affect its lubrication and anti-corrosion performance.

(3) Ensure surface cleanliness: Before using perfluorinated polyether grease, the contact surface should be cleaned first to avoid contamination of perfluorinated polyether grease.

(4) Storage method: perfluorinated polyether grease is more sensitive to humidity, oxygen and temperature, so it should be kept in a dry, cool and ventilated environment when stored to avoid moisture, oxidation and high temperature.

Pay attention to the above points when using perfluorinated polyether grease to ensure its effective lubrication and anti-corrosion properties, extend service life and improve the efficiency of the equipment.
