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

1. Application of dimethyl silicone oil in electromechanical industry

Dimethicone oil is widely used in motors, electrical appliances and electronic instruments as an insulating medium for temperature resistance, arc corona resistance, corrosion resistance, moisture resistance and dust resistance. Wait. It is used as liquid shockproof and damping material in various precision machinery, instruments and meters.

The shock absorption performance of dimethyl silicone oil is less affected by temperature, and it is mostly used in instruments such as aircraft and automobiles in occasions with strong mechanical vibration and large changes in ambient temperature. For shock resistance, damping, stabilizing instrument readings, and also as a liquid spring, used in aircraft landing gear.

2. Dimethicone as defoamer

As a defoaming agent, because dimethyl silicone oil has low surface tension and is insoluble in water, animal and vegetable oils and high-boiling mineral oils, it has good chemical stability and is non-toxic. As a defoaming agent, it has been widely used in petroleum, chemical, medical , pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10-100ppm of silicone oil is added, it has a good defoaming agent effect.

3. Dimethicone as release agent

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

4. Dimethyl silicone oil is used as insulating, dust-proof and mildew-proof coating

For insulating, dust-proof and mildew-proof coatings, dip-coating a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treatment at 250-300 ℃, can form a semi-permanent waterproof, mildew-proof and insulating film.

It is used to treat insulating devices, which can improve the insulation performance of the device: to treat optical instruments, it can prevent lenses and prisms from getting moldy; to treat medicine bottles, it can prolong the shelf life of drugs, and prevent the loss of preparations due to sticking to the wall; It can lubricate the surface of the film, reduce friction and prolong the life of the film.

5. Dimethicone as lubricant

Dimethicone oil is suitable as lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for steel-to-steel rolling friction at high temperature, or as a lubricant for steel and other metals. However, because the lubricating performance of methyl silicone oil is not particularly good at room temperature, in general, it is not recommended as a metal at room temperature between lubricants.

6. Dimethicone as additive

Dimethicone can be used as an additive for many materials, such as a brightener for paint, adding a small amount of silicone oil to the paint can make the paint not float 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, add a small amount of silicone oil to the polishing oil (such as car varnish), can increase the brightness, protect the paint film, and have excellent waterproof effect.

7. Application of dimethyl silicone oil 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 care. Utilizing its defoaming effect, medicines such as oral gastrointestinal defoaming tablets and pulmonary edema defoaming aerosols 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. Some ointments based on silicone oil have good curative effects on scalds, dermatitis, bedsores, etc. Using the anticoagulant effect of silicone oil, it can be used to treat the surface of the blood reservoir and prolong the storage time of blood samples. Also, it can also be used as a condom wet lubricant.

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