According to the scope of application, PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, cross-linked PVC resin. The general-purpose PVC resin is formed by polymerization of vinyl chloride monomer under the action of an initiator; the high polymerization degree PVC resin refers to a resin obtained by adding a chain extender in a vinyl chloride monomer polymerization system; the crosslinked PVC resin is A resin obtained by polymerizing a crosslinking agent containing a diene and a polyene in a vinyl chloride monomer polymerization system

The softening point of the polyvinyl chloride resin is low, about 75-80 ° C, and the embrittlement temperature is lower than -50 ~ -60 ° C. The long-term use temperature of most products should not exceed 55 ° C, and the special formula can reach 90 ° C. If the polyvinyl chloride resin is purely a head-like junction, it is afraid of a linear structure, and there is no branching or unsaturated bond inside. Although the C-Cl bond energy is relatively small, the stability of the polyvinyl chloride resin should be relatively high. . However, even if the polyvinyl chloride resin has a high purity, hydrogen chloride gas will start to escape at a temperature of 100 ° C or higher or ultraviolet radiation. It indicates that there are sharp groups or unstable structures in its molecular structure. The longer the time, the more degradation, the higher the temperature, the faster the degradation rate, and the faster the degradation in the presence of oxygen or air.
1 Where are the PVC fittings used?
A: Plastic pipes for drainage, waste water, chemicals, heating liquids and coolants, foods, ultrapure liquids, slurries, gas, compressed air and vacuum systems
2 plastic pipe what material?
A: The general materials are: PVC/PPC/PVC-U/UPVC/PPV, etc.
3 What is the difference between the water supply system and the drainage system and the chemical system in the PVC pipe fittings?
A: PVC pipe fittings used in water supply systems and chemical systems are generally under pressure, such as PN10/PN16, etc., and the material of PVC pipe fittings used in chemical systems is thicker than normal. Pipe fittings used in drainage systems There is usually no pressure requirement, usually with white as the main color. The color of the water supply system and chemical system is generally grey or dark gray.
