1. Application in the electromechanical industry
Dimethyl silicon oil is widely used in motors, electrical appliances, electronic instruments as temperature resistance, arc resistance corona, corrosion resistance, moisture-proof, dustproof insulation medium, is also used as transformer, capacitor, TV scanning transformer impregnated agent. In a variety of precision machinery, instruments and instruments, used as liquid shock-proof, damping materials. The shock absorption performance of dimethyl silicon oil is less affected by the temperature, and it is mostly used for the occasions with strong mechanical vibration and large ambient temperature changes, such as the instruments used in aircraft and automobiles. For shock shock, damping, stable instrument reading, but also as a liquid spring, and in the aircraft landing device.
2. Make a defoaming agent
Decoaming agent because of dimethyl silicone oil surface tension is small, and insoluble in water, animal and plant oil and high boiling point mineral oil, good chemical stability, and non-toxic, used as a defoaming agent has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper and other industries, as long as add 10-100PPM silicone oil has a good defoaming agent.
3. Make a mold release agent
As a mold release agent due to the dimethyl silicone oil and rubber, plastic, metal and other non-viscosity, and used as a variety of rubber, plastic products molding processing mold release agent, and used in precision casting. Use it to do release agent not only convenient to release, and make the product surface clean, smooth, clear texture.
4. Make insulation, dust-proof and mildew-proof coating
For insulation, dust proof, mildew proof coating on the glass, ceramic surface coated with a layer of dimethyl silicon oil, and heat treatment at 250-300℃, can form a semi-permanent waterproof, mildew proof and insulating film. The insulation device can improve the insulation performance of the device: the optical instrument can prevent the lenses and prism from mold; the preservation period of the drug; the surface of the film can provide lubrication, reduce friction and prolong the life of the film.
5. As a lubricant
Dimethyl silicone oil is suitable for rubber, plastic bearings, gear lubricant. It can also be used as the rolling friction of steel to steel at high temperature, or a lubricant when the friction between steel and other metals, but because the lubrication performance of methylsilicone oil is not particularly good at normal temperature, generally, it is not recommended as a lubricant between metals at normal temperature.
6. As additives
Two methyl silicon oil can be used as many material additives, such as paint as polish, add a small amount of silicon oil to paint, can make the paint not floating bag, not wrinkle improve the brightness of paint film, add a small amount of silicon oil to ink, can improve the printing quality, add a small amount of silicon oil to polishing oil (such as car polish), can increase light, protect paint film, and has excellent waterproof effect.
7. Application in medical and health care
Dimmethylsilicone oil is not toxic to human body and is not decomposed by body fluids, so it is also widely used in medical and health undertakings. Using its definar effect, made oral gastrointestinal distension tablets, and pulmonary edema defole aerosol and other medicinal purposes. Adding silicone oil to the ointment can improve the penetration ability of the drug to the skin and improve the efficacy. Some plasters based on silicone oil have a very good curative effect on scald, dermatitis, bedsores, etc. The anticoagulant effect of silicone oil can be used to treat the surface of the blood reservoir, and prolong the storage time of blood samples. It can also be used as a wet lubricant and it does not kill sperm.
8. Other aspects
Diethylsilicone oil has many uses in other ways. Such as: the use of its high flash point, no smell, no smell, colorless, transparent and non-toxic to the human body and other characteristics, in the steel, glass, ceramics and other industrial and scientific research, as a heat carrier in the oil bath or thermostat. Using its good shear resistance performance, can do hydraulic oil, especially aviation hydraulic oil. The treatment of the rayon spinning head can eliminate static electricity and improve the quality of wire drawing. Adding silicone oil to cosmetics can improve the moisturizing and protective effect of the skin.
