Dimethylsilicone oil is a new synthetic liquid to semi-solid polymer compound, because of its physiological inertia, good chemical stability, electrical insulation, high and low temperature resistance, softness and lubricity, etc., widely used in defoaming, electrical insulation, demudding, painting, waterproof, dustproof, lubrication and other aspects. In medicine, the main use of its anti-foaming effect can reduce the amount of gas in the gastrointestinal tract, in the gastroenteroscopy and various endoscopic surgery operations, taking dimethylsilicone oil can reduce the interference of gas, conducive to clear vision and operation.
Commonly used as advanced lubricating oil, shock-proof oil, insulating oil, defoamer, release agent, polishing agent and vacuum diffusion pump oil. In a variety of silicone oils, methyl silicone oil is the most widely used, is the most important variety of silicone oil, followed by methyl phenyl silicone oil. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, nitrile silicone oil and so on. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Dimethylsilicone oil is tasteless, non-toxic, has physiological inertia, good chemical stability, electrical edge and weather resistance, wide viscosity, low freezing point, high flash point, good hydrophobic performance, and has a high shear resistance, can be used in 50 ~ 180oC temperature for a long time, widely used as insulation, lubrication, shock proof, dust proof oil, dielectric liquid and heat carrier. It is used as an additive for defoaming, film removal, paint and daily cosmetics, etc.
1. The role of demoulding in rubber, plastic and metal due to the non-stick property of dimethylsilicone oil and rubber, metal, etc., can be used for the demoulding of polyurethane microporous elastomer molded products, and can also be used for the demoulding of crusts polyurethane molded products, rubber products, ABS molded products, etc. The main advantages of the release agent are small release force, no pollution, convenient transportation, and the surface of the product is clean, smooth, and the texture is clear. With the rapid development of polyurethane industry, silicone oil release agent market is expanding.
2. The application of silicone oil in the textile industry Silicone oil in the textile and garment industry can be used as fabric softener, lubricant, water repellent, finishing agent and so on. In order to meet the high-end needs of textiles, chemical manufacturers are also constantly developing silicone oils that can be used in bath and feel good with various functional additives such as water repellents, flame retardants, antistatic agents, and color fixing agents. In addition, in order to improve the performance of the fabric, there are silicone products that can be used in the same bath with dyeing, silicone oil for cotton with cool feeling, silicone products that can improve the feel of the fabric, and can give the fabric excellent darkening effect, good storage stability, does not affect the color fastness, feel good organosilicon darkening agents, etc. In addition to the functionalization of textiles as an additive, silicone products will also be used in other areas of textiles, such as the coating of fabrics formed by the combination of silicone and polyurethane; Silicone and acrylic polymerization to form fabric printing; Organosilicon and organofluorine are combined to form waterproof coating on fabric surface.
3. The application of silicone oil defoamer Silicone oil defoamer generally has a high defoamer efficiency, and the commonly used silicone defoamer is prepared with silicone oil as the base component, with appropriate solvents, emulsifiers or inorganic fillers. Silicone defoamer is a kind of defoamer with low toxicity, anti-oxidation and strong defoamer, so it is widely used in printing and dyeing industry and waste water defoamer industry.
