PVC plastic pipe element is with high mechanical properties are high, electrical insulating property is good, excellent in flame retardance, chemicals-resistant, cheap etc.
Advantage is widely used in the daily lifes such as industry, agricultural, building, traffic；But polyvinyl chloride resin Vicat softening point itself is low and low temperature
Brittleness limits its use scope；Common PVC tubing can only delivery temperature be no more than 45 DEG C of cold water, because of the toughness of PVC material
Deficiency, it occur frequently that the problems such as pipeline breaking；And PVC pipeline below 5 DEG C of environment temperature shows strong black brittleness, gives
The expansion of PVC products is many with limitation；Thus market proposes PVC pipeline product the requirement of higher；There is an urgent need to one kind
High temperature resistant, anti-impact, the PVC modified material pipelines of high intensity.
CPVC chliorinated polyvinyl chlorides are made by polyvinyl chloride resin is chlorination modified, are a kind of model engineering plastics.PVC resins pass through
After superchlorination, the scrambling increase of strand arrangement, polarity increase, increases the dissolubility of resin, chemical stability increase,
So as to improve the heat resistance of material and the performance of the corrosion of acid and alkali resistance, salt, oxidant etc..Chlorinity is brought up to by 56%
63-69%, vicat softening temperature bring up to 90-125 DEG C, maximum operation (service) temperature is up to 110 DEG C, for a long time by 72-82 DEG C
Temperature in use is 95 DEG C.Therefore, CPVC products have the superior physics and chemistry such as heat-resisting, weathering, resistant to chemical media burn into be fire-retardant
Energy.
HPVC polychloroethylene with high polymerization degree is a kind of excellent raw material, and compared with common PVC, HPVC is due to its molecular weight
Height, molecular chain length and crimpiness is big, the entanglement point of molecule interchain increases, and makes the active force of HPVC molecule interchains strengthen, strand
Between sliding it is difficult；Therefore HPVC can provide high mechanical property and heat resistance, have the excellent properties of rubber like.
