The role of dimethyl silicone oil

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.

Application in the electromechanical industry: Dimethicone 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. It is also used in transformers, capacitors, televisions The impregnating agent of the scanning transformer of the machine, etc. It is used as liquid shockproof and damping material in various precision machinery, instruments and meters.

As a defoaming agent: due to the small surface tension of dimethyl silicone oil, and insoluble in water, animal and vegetable oils and high-boiling mineral oils, it has good chemical stability and is non-toxic. Medical, pharmaceutical, food processing, textile, printing and dyeing, paper and other industries.

As a mold release agent: due to the non-stickiness of dimethyl silicone oil and rubber, plastics, metals, etc., it is also used as a mold release agent for various rubber and plastic products molding and processing, 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.

For insulating, dust-proof and mildew-proof coating: dip-coat a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treatment at 250-300 ℃, it can form a 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; The surface of the film film can be lubricated, reduce friction and prolong the life of the film.

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 lubricant at room temperature. Intermetallic lubricant.

As an additive: Dimethicone can be used as an additive for many materials, for example, it can be used 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 paint. In the ink, the printing quality can be improved. Adding a small amount of silicone oil to the polishing oil (such as car varnish) can increase the brightness, protect the paint film, and have an excellent waterproof effect.
