Dimethicone application
Dimethicone has various excellent properties, so it has been widely used in various sectors of industrial and agricultural production, defense industry, scientific research, medical and health and other sectors. It is widely used in electrical insulation, demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low humidity, etc.  

1. Application in the electromechanical industry
Dimethyl silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulating medium with temperature resistance, arc corona resistance, corrosion resistance, moisture resistance, and dust resistance. It is also used as an impregnant for scanning transformers of transformers, capacitors, and televisions. Wait. It is used as liquid anti-vibration and damping material in various precision machinery, instruments and meters. The anti-vibration performance of simethicone is less affected by temperature, and it is mostly used in the occasions with strong mechanical vibration and large changes in ambient temperature, such as the instruments used in airplanes and automobiles. It is used for anti-vibration, damping, and stable instrument readings, and can also be used as a liquid spring and used in the landing gear of an aircraft.  

2. As defoamer
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 defoaming agent, it has been widely used in petroleum, chemical and medical , Pharmacy, food processing, textile, printing and dyeing, papermaking and other industries, as long as the addition of 10-100PPM silicone oil has a good defoaming effect.  

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

4. For insulation, dust-proof and mildew-proof coating
For insulation, dust-proof and mildew-proof coating, dip a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treatment at 250-300℃ to form a semi-permanent layer of waterproof, mildew-proof and insulating properties的膜。 The 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 to treat medicine bottles to extend the shelf life of medicines and prevent the loss of preparations due to sticking to the wall; The surface of the film can be used for lubrication, reduce friction, and extend the life of the film.  

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

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

7. Application in medical and health
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 services. Taking advantage of its antifoaming effect, oral gastrointestinal Xiaoshang tablets and pulmonary edema antifoaming aerosols have been prepared for medicinal purposes. 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
There are many other uses for simethicone. 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 research 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.
