Please note: Five precautions in the production process of PVC pipes PVC pipe is one of the most widely used pipes in the pipe industry. It is used frequently in construction and decoration. Therefore, the quality of PVC pipe is very strict, and there are many precautions in the production process. PVC pipe manufacturer Peida Plastics will tell you in detail today what matters need to be paid a
What are the hazards to the body during the production of PVC pipes? The HCL gas released by PVC in the production process is harmful to the human body, but there is generally no problem with good ventilation. PVC pipes are soft and hard. Generally, a large amount of plastic PVC pipes are added with plasticizers, which may be environmentally friendly plasticizers containing phthalates. Pay atten
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
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
