Silicone oil is a product widely used in production and life. Dimethyl silicone oil has various excellent properties, so it has been widely used in various sectors of industrial and agricultural production, defense industry, scientific research and medical and health sectors. It is widely used in electrical insulation, demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low humidity, etc. Let’s take a look at the specific uses of dimethicone.
1. Application in the electromechanical industry: Dimethyl silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulating medium that is temperature-resistant, arc-corona resistant, corrosion-resistant, moisture-proof, and dust-proof. It is also currently used in transformers and capacitors. , impregnating agent for TV scanning transformers, etc. It is used as liquid anti-shock and damping material in various precision machinery, instruments and meters. The shock absorbing performance of dimethyl silicone oil is less affected by temperature. It is mostly used in instruments with strong mechanical vibrations and large changes in ambient temperature, such as instruments in aircraft and automobiles. It is used for shockproofing, damping, and stabilizing instrument readings. It can also be used as a liquid spring and is used in aircraft landing devices.
2. As a defoaming agent: Since dimethyl silicone oil has a small surface tension and is insoluble in water, animal and vegetable oils and high-boiling point mineral oils, it has good chemical stability and is non-toxic. It has been widely used as a defoaming agent in petroleum, oil and gas industries. In chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10-100PPM silicone oil is added, it will have a good defoaming agent effect.
3. As a release agent: Due to the non-stickiness of dimethyl silicone oil to rubber, plastics, metals, etc., it is also used as a release agent for the molding and processing of various rubber and plastic products, and in precision casting. Using it as a release agent not only facilitates demoulding, but also makes the surface of the product clean, smooth and clear in texture.
4. For insulation, dustproof and anti-mildew coating: dip-coat a layer of dimethyl silicone oil on the surface of glass and ceramics, and heat treat it at 250-300℃ to form a semi-permanent waterproof and anti-mildew layer. and insulating films. Used to treat insulating devices, it can improve the insulation performance of the device: used to treat optical instruments, it can prevent lenses and prisms from getting moldy; used to treat medicine bottles, it can extend the shelf life of medicines and prevent preparations from being lost due to sticking to the wall; It can lubricate the surface of film film, reduce friction and extend the life of the film.
5. As a lubricant: Dimethyl silicone oil is suitable for use 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 for friction between steel and other metals. However, since the lubricating properties of methyl silicone oil are not particularly good at room temperature, it is generally not recommended as a lubricant at room temperature. Metal-to-metal lubricant.
6. As an additive: Dimethyl silicone oil can be used as an additive for many materials. For example, it can be used as a gloss enhancer for paint. Adding a small amount of silicone oil to the paint can make the paint non-floating and wrinkle-free and improve the brightness of the paint film. Add a small amount of silicone oil to the paint. Adding silicone oil to ink can improve printing quality. Adding a small amount of silicone oil to polishing oil (such as automotive varnish) can increase brightness, protect the paint film, and have excellent waterproofing effects.
7. Application in medical and health care: 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 anti-foaming effect, oral gastrointestinal anti-bloating tablets, pulmonary edema anti-foaming aerosols and other medicinal uses have been made. Adding silicone oil to the ointment can improve the penetration of the drug into the skin and improve the efficacy. Some plasters based on silicone oil are very effective in treating burns, dermatitis, bedsores, etc. The anticoagulant effect of silicone oil can be used to treat the surface of the blood reservoir and extend the storage time of blood samples.
8. Other aspects: Dimethicone has many uses in other aspects. For example, by utilizing its characteristics such as high flash point, odorless, colorless, transparent and non-toxic to the 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. Due to its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Use it to treat rayon spinning heads to eliminate static electricity and improve spinning quality. Adding silicone oil to cosmetics can improve the moisturizing and protective effects on the skin, etc.
The above is an introduction to the uses of dimethicone. It can be seen that dimethyl silicone oil has a wide range of uses, and whether it is used as a defoaming agent or additive, whether it is used in the mechanical and electrical industry or in medical and health care, it has many advantages. 2. Methicone is indeed a product worth choosing.
