The causes and solutions of abnormal phenomena in PVC pipes processing (Manufacturing process of PVC pipe)The following are the causes and corresponding solutions of abnormal phenomena that are likely to occur during the processing of PVC pipes.
Processing technology of chlorinated polyvinyl chloride (PVC-C) pipes - 2 When setting the process temperature, the curve should be kept as gentle as possible, which is beneficial to the plasticizing quality of the CPVC resin. The sudden rise and fall of the curve is not conducive to the plasticization of the pipe. Generally, a "U" shaped curve is more appropriate.
Processing technology of chlorinated polyvinyl chloride (PVC-C) pipes - 1 1. ExtruderExtrusion processing of CPVC pipes usually uses parallel or conical twin-screw extruders.
Formula composition of chlorinated polyvinyl chloride (PVC-C) pipes - 2 2. LubricantsThe role of lubricants and heat stabilizers are equally important.Adding too little, will cause processing difficulties, and even bring considerable damage to the equipment; adding too much, not only affect the quality of plasticization, but also reduce the Vicat softening temperature of the pipe. Therefore, how to balance the dosage of lubricant is the key, but als…
Formula composition of chlorinated polyvinyl chloride (PVC-C) pipes - 1 Chlorinated polyvinyl chloride resin (hereinafter referred to as CPVC resin) was successfully developed in 1958 by BFGoodrich from USA, which is the product of chlorination of polyvinyl chloride resin (PVC resin).After chlorination of PVC, the chlorine content can be increased from 57% to 64% - 75%, with the increase in chlorine content, the corresponding temperature resistance,…
