Characteristics of the barrel of a dual alloy rubber extruder:
1. Wear resistant and have a long lifespan;
2. High temperature resistance, no deformation at high temperatures;
3. Corrosion resistance, materials have corrosiveness;
4. Good cutting performance;
5. High strength, capable of withstanding large torque and high speed;
6. After heat treatment, the residual stress is small and the thermal deformation is small.
Characteristics of the barrel of a dual alloy rubber extruderThe screw rotates inside the barrel, and the friction between the material and the two gradually wears down the working surface of the screw and barrel: the diameter of the screw gradually decreases, and the diameter of the inner hole of the barrel gradually increases. In this way, the clearance between the screw and the barrel gradually increases as they wear out. However, due to the unchanged resistance of the machine head and splitter plate in front of the barrel, this increases the leakage flow of the extruded material as it advances, that is, the flow of material from the diameter gap towards the feeding direction increases. As a result, the production volume of the extruder decreased. This phenomenon also increases the residence time of materials in the barrel, causing material decomposition. If it is polyethylene, the hydrogen chloride gas produced by decomposition enhances the corrosion of screws and barrels.
