Dimethicone has various excellent characteristics. Due to the small intermolecular force, the molecules are in a spiral structure, and the methyl groups are arranged outwards and can rotate freely. Therefore, it has a series of characteristics, such as colorless and transparent liquid, wide viscosity range, Low temperature viscosity coefficient, large expansion coefficient, low vapor pressure, high flash point, high temperature resistance, low temperature resistance, weather resistance, radiation resistance, low surface tension, high compression rate, oxygen plasma resistance, high insulation, shear resistance, Film, water repellency, defoaming, demoulding, high gloss, inert to materials, chemically inert, non-corrosive and physiologically inert, etc. It is these characteristics that determine its broad application. It is widely used in electrical insulation, demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, wetting, etc.

1. Application in the electromechanical industry: Dimethicone is widely used in motors, electrical appliances, and electronic instruments as an insulating medium that is resistant to temperature, arc corona, corrosion, moisture, and dust. It is also used as a transformer and capacitor. , The impregnant of the scanning transformer of the TV, etc. Used as liquid shockproof and damping material in various precision machinery, instruments and meters. The shock absorption performance of simethicone is less affected by temperature. It is mostly used in occasions with strong mechanical vibration and large changes in ambient temperature, and used in aircraft and automobile instruments. It is used for anti-vibration, damping, and stable instrument readings. It can also be used as a liquid spring for the landing gear of an aircraft.

2. As a defoaming agent: due to its low surface tension and insoluble in water, animal and vegetable oils and high-boiling mineral oils, it has good chemical stability and non-toxicity. As a defoamer, it has been widely used in petroleum, In the chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10x10-6～10x10-6 silicone oil is added, it has a good defoaming agent.

3, as a mold release agent: due to the non-stickiness of simethicone with rubber, plastic, metal, etc., it is also used as a mold release agent for various rubber and plastic products processing, and used in precision casting. Using it as a release agent is not only convenient for release, but also makes the surface of the product clean and smooth with clear texture.

4. For insulation, dustproof and mildew proof coating: dip a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treatment at 250~300°C to form a semi-permanent waterproof and mildew proof layer And insulating film. Used to treat insulating devices can improve the insulation performance of the device: use it to treat optical instruments to prevent molds and prisms; use it to treat medicine bottles to prolong the shelf life of the medicine and prevent the loss of the preparation due to sticking to the wall; It treats the surface of the motion picture film, which can play a lubricating effect, reduce friction and extend the life of the film.

5. Used as a lubricant: Dimethicone is suitable for use as a lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for rolling friction between steel and other metals at high temperatures. However, since the lubricating performance of methyl silicone oil at room temperature is not particularly good, it is generally not recommended as a lubricant for metals at room temperature. Lubricant.

6. Used as an additive: Dimethicone can be used as an additive for many materials. For example, it can be used as a paint brightener. Add a small amount of silicone oil to the paint to prevent the paint from floating or wrinkle to improve the brightness of the paint film. Add a small amount Silicone oil added to the ink can improve the printing quality. Adding a small amount of silicone oil polishing oil (such as car polish) can increase the brightness, protect the paint film, and have an excellent waterproof effect.

7. Application in medical and health care: Dimethicone is non-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 antifoaming effect, oral gastrointestinal Xiaoshang tablets, pulmonary edema antifoaming aerosol and other medicinal applications have been prepared. Adding silicone oil to the ointment can improve the penetration ability of the drug into the skin and improve the efficacy of the drug. Certain ointments based on silicone oil have good curative effects on burns, dermatitis, bedsores, etc. The use of silicone oil's anticoagulant effect can be used to treat the surface of blood reservoirs and prolong the storage time of blood samples.

8. Other aspects: Dimethicone has many uses in other aspects. For example, using its high flash point, odorless, colorless, transparent, and non-toxic to humans, it can be used as a heat carrier in oil baths or thermostats in industries and scientific researches such as steel, glass, and ceramics. With its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat the rayon spinning head can eliminate static electricity and improve the quality of spinning. Adding silicone oil to cosmetics can improve the skin's moisturizing and protective effects and so on.
