Methyl hydrogen silicone fluid
is the earliest organosilicon polymer used commercially. it is widely used in electrical, mechanical, coating, medical and other sectors of the national economy because of its excellent oxidation resistance, shear resistance, low surface tension, hydrophobic, defoaming and other properties.
In the production process of methyl hydrogen silicone fluid, the catalyst decomposes to produce pungent gas, which is partially mixed in the system, making the silicone oil smelly and its application restricted. Therefore, in the process of methyl silicone oil production, take measures to eliminate odor.
The production process of methyl hydrogen silicone fluid is carried out in a reaction kettle. The whole production process includes copolymerization process, boiling process, heat preservation process and cooling process,etc. During all process, low boiling gas is generated. After the condensed by condenser (circulating water, the condensation temperature is room temperature) , guide the condensate gas to the activated carbon absorption device for treatment and then it is discharged at an altitude of 15m through the exhaust cylinder.
Different viscosity of methyl hydrogen silicone fluid will infiltrate each other. Since the lightning of low viscosity silicone oil is low, the lightning of mixed viscosity of methyl hydrogen silicone fluid may be reduced. The chemical properties of methyl hydrogen silicone fluid are relatively stable, but the viscosity will change when it is in contact with strong acid, strong base or metal aluminum and tin at high temperature.
Tests show that in 90-120 ℃, adopt temperature control method and method of inleting bubble through dry air when it is below 140 ℃. Colorless, odorless and qualified methyl hydrogen silicone fluid can be obtained, and the average conversion rate increased from 65% to more than 80%.
