Main features and uses:
Dimethylsilicone oil is odorless and non-toxic, with physiological inertness, good chemical stability, electrical stability, and weather resistance. It has a wide viscosity range, low freezing point, high flash point, good hydrophobicity, and high shear resistance. It can be used for a long time at temperatures ranging from 50 to 180 ° C. It is widely used as an insulating, lubricating, shockproof, dustproof oil, dielectric fluid, and heat carrier. It is also used as an additive for defoaming, defoaming, painting, and daily cosmetics.
Chemical applications
Dimethylsilicone oil has various excellent properties, making it widely used in various sectors of industrial and agricultural production, national defense industry, scientific research, and medical and health sectors. It is widely used in electrical insulation, demolding, defoaming, damping, shock resistance, rolling, dust prevention, waterproofing, high and low humidity, and other aspects.
1. Application in the electromechanical industry
Dimethylsilicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulation medium that is resistant to temperature, arc corona, corrosion, moisture, and dust. Currently, it is also used as an impregnating agent for scanning transformers in transformers, capacitors, and televisions. Used as a liquid shock-absorbing and damping material in various precision machinery, instruments and meters. The shock-absorbing performance of dimethyl silicone oil is less affected by temperature, and it is mostly used in instruments such as aircraft and automobiles in situations with strong mechanical vibrations and large environmental temperature changes. Used for shock resistance, damping, and stabilizing instrument readings, it can also serve as a liquid spring and is used in aircraft landing devices.
2. As an defoamer
As a defoamer, dimethyl silicone oil has low surface tension and is insoluble in water, animal and vegetable oils, as well as high boiling mineral oils. It has good chemical stability and is non-toxic. It has been widely used as a defoamer in industries such as petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, and papermaking. As long as 10-100PPM of silicone oil is added, it has a good defoaming effect.
3. As a release agent
As a release agent, dimethyl silicone oil is not sticky to rubber, plastic, metal, etc. It is also used as a release agent for various rubber and plastic product molding and processing, as well as in precision casting. Using it as a demolding agent not only facilitates demolding, but also makes the surface of the product clean, smooth, and with clear textures.
4. Apply insulation, dust and mold resistant coatings
Dip a layer of dimethyl silicone oil on the surface of glass and ceramics as an insulation, dust-proof, and anti mold coating, and heat treat at 250-300 ℃ to form a semi permanent waterproof, anti mold, and insulating thin film. Using it to process insulating devices can improve their insulation performance: using it to process optical instruments can prevent mold from forming on lenses and prisms; Using it to handle medication bottles can extend the shelf life of the drug without causing any loss of the preparation due to sticking to the wall; Using it to treat the surface of film can provide lubrication, reduce friction, and extend the lifespan of the film.
5. As a lubricant
Dimethylsilicone oil 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 other metals at high temperatures, or for friction between steel and other metals. However, due to the poor lubrication performance of methyl silicone oil at room temperature, it is generally not recommended as a lubricant between metals at room temperature.
6. As an additive
Dimethylsilicone oil can be used as an additive for many materials, such as as as a brightener for paint. Adding a small amount of silicone oil to the paint can prevent the paint from floating or wrinkling, and improve the brightness of the paint film. Adding a small amount of silicone oil to ink can improve printing quality. Adding a small amount of silicone oil to polishing oil (such as car polish) can increase brightness, protect the paint film, and have excellent waterproof effects.
7. Application in healthcare
Dimethylsilicone oil has no biological toxicity to the human body and is not decomposed by body fluids, so it is also widely used in the medical and health industry. By utilizing its defoaming effect, oral gastrointestinal distension tablets and pulmonary edema defoaming 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 enhance its efficacy. Some ointments based on silicone oil have good therapeutic effects on burns, dermatitis, pressure ulcers, etc. By utilizing the anticoagulant effect of silicone oil, it can be used to treat the surface of blood storage devices and extend the storage time of blood samples. It can also be used as a wet lubricant for condoms, and it does not kill sperm.
8. Other aspects
Dimethylsilicone oil has many other uses. For example, using its high flash point, odorless, colorless, transparent, and non-toxic properties, it can be used as a heat carrier in oil baths or thermostats in industries and scientific research such as steel, glass, ceramics, etc. By utilizing its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat artificial silk spinning heads can eliminate static electricity and improve drawing quality. Adding silicone oil to cosmetics can enhance the moisturizing and protective effects on the skin, and so on.
