The rubber extruder is a basic equipment in the rubber industry and one of the key equipment that affects product quality. It plays a very important role in the production process of tires and rubber products. The development of foreign rubber extruders has experienced Plug extruder, screw type hot feed extruder, ordinary cold feed extruder, main and auxiliary thread cold feed extruder, cold feed exhaust extruder, pin cold feed extruder, Compound extruder and other stages. Rubber extruder is used for pressing, filtering and encapsulating rubber semi-products. Structural features: The screw and inner sleeve are made of nitrided steel, which has good wear resistance and corrosion resistance sex.
The screw extrusion of rubber extruder compound is one of the older fields of extrusion technology, which can be traced back to the 19th century. Rubber extruders are obviously different from thermoplastic extruders. First of all, rubber extrusion It is carried out at a lower temperature (up to 130 °C). Secondly, rubber strips are often added to rubber extrusion (only in exceptional cases, pellets are added), and they do not undergo phase change or phase change in the screw extruder system. A large degree of thickening effect. This is not like thermoplastics. Thermoplastics have to be processed at a temperature of 180^-300°C (or higher) in the screw extruder, and low-density solid particles are often added to the extruder. When the pellets move forward along the screw, the melting well is compacted.
Rubber extruders are usually classified into hot-feeding and cold-feeding machines. In the hot-feeding extruder, the rubber compound is heated by the mechanical action of the open mill, and these heated rubber strips are cut and continuously extruded. Feeding from the machine. In the cold feed screw extruder, the rubber strip at room temperature is added to the extruder. The rubber extruder is often classified according to whether it is used for exhaust.
