简体中文The quality of the screw and barrel of the rubber screw barrel directly affects the quality and production efficiency of the product. When these two parts are severely worn or broken, they need to be repaired. The process in the rubber screw barrel is explained by the theory of resistance flow. In addition to screw speed, important process parameters are output, head pressure, specific energy, and extrudate temperature.
How to repair the rubber extruder screw after it is broken? We can re-manufacture a new screw on the basis of the old screw. The surface of the screw can also be thermally sprayed with wear-resistant alloy and then polished to improve the corrosion resistance and wear resistance of the screw.
It is also possible to plate a layer of hard chromium on the surface of the screw. This chromium molecule has good corrosion resistance and wears resistance, but the hard chromium layer is relatively easy to fall off. After the screw of the rubber extruder is broken, whether to replace or repair it can be determined according to the price. If the repair cost is more expensive than replacing a new one, it is best to replace it with a new one.
