In the production of high-viscosity to ultra-high-viscosity product materials that are common on the market now, the silicone rubber kneader is one of the main mixing equipment. Of course, many users often confuse the silicone rubber kneader with the internal mixer, so let’s briefly describe the differences between the two devices.
The silicone rubber kneader is a pair of blades (usually Z-shaped) that cooperate with each other to produce a strong shearing action, so that the semi-dry state or rubber-like thin plastic slurry can make the material react quickly to obtain uniform mixing. Stirring equipment is an ideal equipment for mixing, kneading, crushing, dispersing, and repolymerizing various chemical products of various high-viscosity elastic-plastic materials. It has the advantages of uniform mixing and high kneading efficiency, and is widely used in high-viscosity sealants. , silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, also used in batteries, inks, pigments, dyes, medicine, resins, plastics, rubber, cosmetics and other industries.
The silicone rubber kneader is mainly composed of six parts: kneading part, base part, hydraulic system, transmission system, vacuum system and electric control system. The kneading part is composed of cylinder body, pulp shaft, wallboard, cylinder head and so on. The hydraulic system consists of a hydraulic station to control two small oil cylinders and two large oil cylinders to complete the functions of opening and closing the large cover and turning the mixing cylinder. The electric control system has manual and automatic electric control systems, which can be selected and requested by the user at will, and the operation is convenient and reliable. The transmission system consists of a motor, a reducer and a gear, and the motor is matched according to the model of the silicone rubber kneader. During the transmission process, the synchronous speed can be achieved by the motor, and after passing through the elastic coupling to the reducer, the output device can drive the fast paddle to make it reach the regular speed, and the speed can also be stopped by the frequency converter.
The internal mixer is the abbreviation of the closed rubber mixing machine, which is mainly used for plasticizing and mixing of rubber. It is a high-strength intermittent mixing equipment developed on the basis of the open mixer. Internal mixer is a kind of machine with a pair of rotors with specific shape and relative rotation, which intermittently plasticizes and kneads polymer materials in a sealed state with adjustable temperature and pressure. It mainly consists of a mixing chamber, a rotor , Rotor sealing installation, feeding and pressing installation, unloading installation, transmission installation and machine base and other parts. The emergence of the internal mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plasticizing and mixing, and it is constantly being developed and improved.
The internal mixer is generally composed of a mixing chamber, two relatively rotating rotors, an upper top bolt, a lower top bolt, a temperature measurement system, a heating and cooling system, an exhaust system, a safety device, a discharge device and a recording device. There are spiral ribs on the surface of the rotor, and the number of ribs is two-sided, four-sided, six-sided, etc. The cross-sectional geometry of the rotor is triangular, cylindrical or elliptical, and there are two types: tangential type and meshing type. . The temperature measurement system is composed of thermocouples, which are mainly used to measure the temperature change in the mixing chamber during the mixing process; the heating and cooling system is mainly used to control the temperature of the rotor and the outer wall of the mixing chamber.
