Silicone oil: When talking about silicone oil, the first thing that most people think of is probably shampoo. Most domestic shampoos contain one or more types of silicone oil. from individual manufacturers
When silicone-free shampoos began to be sold, consumers began to accept that using silicone-containing shampoos could clog pores, cause hair loss, and even cause cancer, as did silicone oils.
Hajime entered the public eye with a bad reputation.

In fact, silicone oil is not just shampoo, it has penetrated into every aspect of life. You know, silicon. What is silicone oil?

Generally speaking, silicone oil refers to linear polysiloxane, which is liquid at room temperature. This is a general term for a large category of products. Chemically speaking, the structural formula of most silicone oils is

The main results are as follows: Among them, hydrogen, methyl, ethyl, phenyl and chlorophenyl are common R groups. The difference in R groups will directly affect the performance of silicone oil and its scope of use.



Silicone oil as lubricating liquid

Dimethyl silicone oil and low phenyl silicone oil have good lubrication to rubber and plastics, good low temperature properties and chemical inertness, and can be used for the lubrication of plastic gears, plastic bearings, rubber seals, valves in refrigeration equipment, instruments, etc.; Medium Phenyl silicone oil can be used for the lubrication of higher-temperature rolling bearings, clocks, and small precision instruments; high-phenyl silicone oil can be used for the lubrication of high-temperature and relatively stable places, such as conveyor belts, locking pins, and boiler doors.

Silicone oil as hydraulic oil

Hydraulic transmission uses liquid pressure energy for energy conversion, and adopts hydraulic transmission technology to simplify the size of the equipment, reduce the quality of the transmission mechanism, and improve operating efficiency. Sensitivity and smoothness and other advantages. In the national standard GB/T7631.2-1987, hydraulic oil is divided into HH, HL, HM, HR, HG and other types of hydraulic oil, which can be used in different working pressures, working temperatures and operating environments. From various types of hydraulic systems in the manufacturing industry to large mobile hydraulic equipment in excavators, cranes and other places, commonly known as oil cylinders and the hydraulic oil used can be seen everywhere. Hydraulic oil is used in daily automotive hydraulic power steering systems.

Silicone grease

The silicone oil grease can be used for rolling bearing and sealing operations under high temperature, high speed, long time and other conditions. Low phenyl silicone oil-lithium soap grease can be used for instruments, small
Bearings used in motors, etc.; medium phenyl silicone oil-lithium soap grease can be used for some ball bearings with higher operating temperatures in textile, glass and other industries; high phenyl silicone oil-carbon black grease can be used for slow-speed rolling bearings. The temperature can reach 350℃ in a short time without any problem.

Silicone oils are still used in many areas. With the development of science and technology, more silicone oils will be invented and promoted, but we don’t know that these things are also used.
Silicone oil or silicone oil is also used.
