Silicones, commonly known as silicone oil or dimethylsilicone oil, has the formula: (CH3) 3sio (CH3) 2sionsi (CH3) 3, which is a polymer of organosilicon oxides. It is a series of polydimethylsiloxanes with different molecular weight. The viscosity increases with the increase of molecular weight. The product has stable chemical properties, strong hydrophobicity, insoluble in water, soluble in gasoline, toluene and other non-polar solvents. The electrical performance of silicone rubber is very little affected by temperature. It is a kind of excellent and stable insulating material. The wires and cables made of silicone rubber can not only work in harsh environment, but also have high reliability guarantee under full load operation conditions. Especially with the standards of wires and cables and accessories in China being further integrated into international standards, silicone rubber has become the rubber in the power industry The potential products are widely used in the main adhesives for insulators, high-performance wires and cables and accessories. Compared with the traditional heat shrinkable cable accessories, the silicon rubber prefabricated cold shrinkable cable accessories have greatly improved in performance, quality, power grid safety, etc.; they have excellent resistance to leakage and tracking, excellent radiation resistance, good hydrophobicity, and can be bonded with the cable body after installation, which can effectively reduce the discharge of the cable terminal.

Internal mixing twin screw granulator for silicone Masterbatch

Function of internal mixing twin-screw silicone masterbatch granulator:

The function of the master granulator is to transform the solid plastic into uniform melt by means of heating, pressing and shearing, and to send the melt to the next process. The production of melt involves additive such as mixed color masterbatch, mixed resin and regrinding. The product melt must be uniform in concentration and temperature. The pressure must be large enough to extrude the viscous polymer.

All the above processes are completed by a cylinder with a screw and a spiral channel. The plastic particles enter the barrel through a hopper at one end of the barrel, and then are conveyed to the other end of the barrel through a screw. In order to have enough pressure, the depth of the thread on the screw decreases as the distance from the hopper increases. The external heating and the internal heat generated by friction between the plastic and the screw make the plastic soften and melt. Different polymers and different applications often have different design requirements for extruders. Many options involve discharge outlet, multiple feeding ports, special mixing device along the screw, cooling and heating of melt, or no external heat source (adiabatic extruder), relative size of gap change between screw and barrel, and number of screws, etc.
