The role of silicone oil and the method of distinguishing between true and false
To distinguish between true and false silicone oils, you must first understand silicone oil and understand the characteristics of silicone oil.
Silicone oil is a polyorganosiloxane with different polymerization degree chain structure. It is obtained by hydrolysis of dimethyldichlorosilane with water to obtain a polycondensation ring. The ring body is cracked and rectified to obtain a low ring body, and then The ring body, the heading agent and the catalyst are tempered together to obtain a mixture of various polymerization degrees, and the low-boiling substance is removed by distillation under reduced pressure to obtain a silicone oil.
Silicone oil features: excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and small surface tension, in addition to low viscosity temperature coefficient, high compression resistance, and some varieties also have Radiation resistant, non-corrosive to metals, non-toxic, etc.
Silicone oil: commonly used as high-grade lubricants, anti-vibration oils, insulating oils, defoamers, mold release agents, polishing agents and vacuum diffusion pump oils. Among the various silicone oils, methyl silicone oil is the most widely used, and is the most important type of silicone oil, followed by methylphenyl silicone oil. In addition, there are ethyl silicone oil, methylphenyl silicone oil, nitrile-containing silicone oil, and the like. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
