How to solve the problems in the production process of PVC pipe production line 1. There are burn marks on the surface of the tube. The possible reasons are that the temperature of the fuselage or the head is too high; the head and the filter are not cleaned; there are impurities in the pellet; the thermal stability of the raw material is poor or the thermal stability dose is too small; the tem
Common problems, causes and solutions of PVC production and processing (summary) (1) Common problems, causes and solutions of pipes Common problems Possible cause Solution There are lumps in the tube wall (like bubbles). The moisture of the material is too high. Properly increase the mixing temperature and extend the mixing time Impurities mixed in materials Check the source of impuritie
PVC pipe production problems and solutions There are always various problems in the process of PVC pipe production. Only by solving these problems can high-quality PVC pipes be produced. To share with you some PVC pipe production problems and solutions. pvc tube 1. The outer surface of the plastic pipe is rough: adjust the process temperature: reduce the cooling water temperature, the opt
A collection of problems in the production process of PVC pipes Every new operator must have encountered a lot of big and small questions when operating PVC pipe equipment.Here are some solutions to the conventional questions. Main points of PVC pipe production process control 1. Process temperature: During start-up and normal production, temperature is one of the main factors affecting plast
What is the difference between PVC and CPVC? 1. Material characteristics: PVC is polymerized by vinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging and acid and alkali resistance, so it is very suitable for use in chemical pipelines. The mixture of PVC raw materials with a certain amount of solid additives (no plasticizers) is called rigid polyvinyl ch
Differences in performance of PVC, UPVC, CPVC, PP, PE, PB, PVDF plastic pipes PVC PVC (PolyVinylChloride polyvinyl chloride) generally has 7 grades (SG1-SG7) according to the hardness and performance of the material, and the density is about 1.4 g / cm³. Below SG4 is generally a soft product, and a large amount of plasticizer needs to be added during molding. It is mainly used to make artifi
Introduction of CPVC / UPVC pipeline solvent bonding to the quality requirements of the welding agent The solvent bonding of CPVC / UPVC pipeline is to melt and combine the contact surface of the connection part of the pipeline and the pipe fitting with a solvent (or adhesive) to achieve the required shear strength after curing to meet the use of the pipeline system There are strict requirement
Use of glue in CPVC / UPVC pipeline connection 1. Glue: Glue is generally composed of polymer resin and solvent in a certain proportion. When used for pipe bonding, the solvent of the glue will soften and penetrate the outer diameter of the pipe socket and the inner diameter of the socket of the pipe fitting, so that the pipe / pipe fitting can be more closely bonded together when the bonding i
