Silicone oil is a kind of product widely used in production and life. Dimethylsilicone oil has various excellent characteristics, so it has been widely used in various departments of industrial and agricultural production, national defense industry, scientific research and medical and health departments. It is widely used in electrical insulation, demoulding, defoaming, damping, shock-proof, rolling, dust-proof, waterproof, high and low humidity and so on. Let's take a look at the specific uses of dimethyl silicone oil.
1, the application in the mechanical and electrical industry: dimethylsilicone oil is widely used in motors, electrical appliances, electronic instruments as temperature resistance, arc corona resistance, corrosion resistance, moisture, dust insulation medium, is also used as transformers, capacitors, TV scanning transformer impregnating agent. In a variety of precision machinery, instruments and meters, used as liquid shock, damping materials. The shock absorption performance of dimethylsilicone oil is little affected by temperature, and it is mostly used in occasions with strong mechanical vibration and large changes in ambient temperature, such as the instruments used in aircraft and automobiles. It is used for shock-proof, damping, stabilizing instrument readings, and can also be used as a liquid spring in aircraft landing devices.

2, as a defoamer: due to the small surface tension of dimethyl silicone oil, and insoluble in water, animal and plant oil and high boiling point mineral oil, good chemical stability, and non-toxic, used as a defoamer has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper and other industries, as long as 10-100PPM of silicone oil has a good defoamer effect.

3, as a release agent: due to the non-viscosity of dimethyl silicone oil and rubber, plastic, metal, etc., it is also used as a release agent for various rubber and plastic products molding processing, and for precision casting. Using it as a release agent is not only convenient for release, but also makes the surface of the product clean, smooth and clear.

4, for insulation, dustproof, mildew resistant coating: in the glass, ceramic surface dip a layer of dimethylsilicone oil, and after heat treatment at 250-300℃, can form a layer of semi-permanent waterproof, mildew resistant and insulating film. Used to deal with insulation devices, can improve the insulation performance of the device: used to deal with optical instruments, can prevent the lens, prism mold; The treatment of the medicine bottle can extend the storage period of the medicine, and will not cause the loss of the preparation due to wall sticking; It is used to treat the surface of the film, which can play a lubricating role, reduce friction and extend the life of the film.

5, as a lubricant: dimethyl silicone oil is suitable for rubber, plastic bearings, gear lubricants. It can also be used as a lubricant for rolling friction between steel and steel at high temperatures, or for friction between steel and other metals, but because the lubrication performance of methyl silicone oil is not particularly good at room temperature, under normal circumstances, it is not recommended as an inter-metal lubricant at room temperature.

6, as an additive: Dimethyl silicone oil can be used as an additive for many materials, such as paint brightening agent, add a small amount of silicone oil to the paint, can make the paint does not float, does not wrinkle to improve the brightness of the paint film, add a small amount of silicone oil to the ink, can improve the printing quality, add a small amount of silicone oil to the polishing oil (such as automotive polishing oil), can increase brightness, protect the paint film, and has excellent waterproof effect.

7. Application in medical and health care: Dimethylsilicone oil is not toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health care. Taking advantage of its defoaming effect, oral gastrointestinal anti-swelling tablets and pulmonary edema defoaming aerosol have been prepared for medicinal purposes. Adding silicone oil to the ointment can improve the penetration ability of the drug to the skin and improve the efficacy. Some pastes based on silicone oil have a good effect on burns, dermatitis, bedsores and so on. Using the anticoagulant effect of silicone oil, it can be used to treat the surface of blood reservoir and extend the storage time of blood samples.

8, other aspects: dimethyl silicone oil in other aspects there are many uses. Such as: the use of its high flash point, no smell, colorless, transparent and non-toxic to the human body and other characteristics, in steel, glass, ceramics and other industries and scientific research, as an oil bath or thermostat heat carrier. With its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat the spinning head of rayon can eliminate static electricity and improve the quality of drawing. Adding silicone oil to cosmetics can improve the moisturizing and protective effect on the skin.

The above is about the use of dimethyl silicone oil introduction. It can be seen that the use of dimethylsilicone oil is very wide, and whether it is as a defoamer, or an additive, whether it is used in the mechanical and electrical industry or used in medical health, there are many advantages, dimethylsilicone oil is indeed a worthy choice of products.
