Dimethyl silicone oil has a variety of excellent properties, so it has been widely used in industrial and agricultural production departments, national 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 mechanical and electrical industry: dimethylsilicone oil is widely used in motors, electrical appliances, electronic instruments as temperature resistant, arc corona resistant, corrosion-resistant, moisture-proof, dust-proof insulation medium, and also used as impregnant for transformer, capacitor, TV scanning transformer, etc. It is used as liquid shock proof and damping material in various precision machinery, instruments and meters. The shock absorption performance of dimethylsilicone oil is less affected by temperature, so it is versatile
In the case of strong mechanical vibration and large environmental temperature change, it is used in the instrument of aircraft and automobile. It can also be used as a liquid spring in landing device of aircraft.
As defoamer: due to the small surface tension of dimethylsilicone oil, which is insoluble in water, animal and vegetable oil and high boiling point mineral oil, it has good chemical stability and non-toxic. It has been widely used as defoamer in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10 × 10-6 ～ 100 × 10-6 is added
The silicone oil has a good defoamer effect.
As release agent: due to the non stickiness between dimethylsilicone oil and rubber, Plastic and metal, it is also used as a release agent for various rubber and plastic products and in precision casting. It is not only convenient for demoulding, but also makes the surface clean, smooth and clear.
For insulating, dustproof and mould proof coating: dip a layer of dimethylsilicone oil on the surface of glass and ceramic ware and heat treatment at 250 ~ 300 ℃, a semi permanent waterproof, mould proof and insulating film can be formed. It can improve the insulation performance of insulating devices: it can prevent the lens and prism from moldy when it is used to treat optical instruments; it can prolong the storage period of medicine without causing the preparation to lose due to sticking to the wall; it can lubricate the film surface, reduce friction and prolong the film life.
As lubricant: dimethyl silicone oil is suitable for rubber, plastic bearing and gear lubricant. It can also be used as a lubricant for rolling friction between steel and steel at high temperature, or for friction between steel and other metals at high temperature. However, due to the poor lubrication performance of methyl silicone oil at room temperature, it is not recommended to be used as lubricant between metals at normal temperature.
As additive: dimethylsilicone oil can be used as an additive for many materials. For example, adding a small amount of silicone oil into the paint can prevent the paint from floating and wrinkle, and improve the brightness of the paint film. Adding a small amount of silicone oil to the ink can improve the printing quality. Adding a small amount of silicone oil to the polishing oil (such as automobile polish oil) can increase the brightness, protect the paint film and have excellent anti-corrosion Water effect.
Application in medical and health: dimethylsilicone oil has no toxicity to human body and is not decomposed by body fluids, so it is widely used in medical and health undertakings. With its antifoaming effect, oral gastrointestinal Xiaozhang tablets and pulmonary edema defoaming aerosol were prepared. Adding silicone oil to the ointment can improve the penetration of drugs to the skin and improve the efficacy. Some plasters with silicone oil as base oil have good curative effect on scald, dermatitis and bedsore. The anticoagulant effect of silicone oil can be used to treat the surface of blood reservoir and prolong the storage time of blood samples.
