Polyvinyl chloride paipa, fai mai foi paipa pvc, o le paipa lea o le palasitika vevela polymer maualuga na faia e polymerization o le vinyl choride monomer ua faia, ave polyvinyl chloride (PVC) RESINS e avea ma autu autu, faaopoopo antiaging sui talafeagai, meatotino-fa'asa'o sui. ma isi mea, o mea e fausia e ala i auala e pei o le faʻafefiloi, faʻakalena, faʻamalo faʻauma.

Pvc paipa tetee i corrosion e malosi, e fusifusia e faigofie i, PVC ua matua malosi resistibility i oxygenant, redutive sooupu ma malosi acid.But e mafai ona corroded ma le taimi foi inapplicable faafesootai ma hydrocarbon manogi, chlorinated hydrocarbon e pei o le vitriol. suauu, acid nitric concentrated e mafiafia oxidizing acid.

Ae, o le paipa pvc, aemaise lava le UPVC paipa teteʻe i le vevela e leaga, ma le malosi tensile siʻosiʻomaga e sili atu i le 60 ℃, ma i lalo o le vevela o le siosiomaga, Vybak vai fana teteʻe e faʻaitiitia ai le teʻi. malepelepe;E le gata i lea, o le faatinoga o paipa pvc e tetee atu i te'i e leaga foi.

O se ituaiga o paipa polychloroethylene maualuga malosi, e faia e le vaega o le vaega mamafa:

100~150 vaega ole polyvinyl chloride (PVC) RESINS,

20 ~ 30 vaega o resini polyvinyl chloride chlorinated,

6-8 vaega o resini acrylic,

2~4 vaega ole Poly(Trimethylene Terephthalate),

3~6 vaega ole urethane,

10~15 vaega, pa'u styrene-butadiene(SBR),

1 ~ 2 vaega ole methyl methacrylate,

1 ~ 2 vaega o le phosphite taʻitaʻi dibasic,

2 ~ 4 vaega o le uisua silicon carbide,

1~2 vaega, alava tioata,

2 ~ 3 vaega ole polymeric amide,

2-4 vaega o le diphenyl phosphites,

2 ~ 3 vaega o faʻamautu,

2~6 vaega ole Chlorinated Polypropylene III acid-butadiene-styrene copolymer,

1 ~ 2 vaega o le antiaging agent,

1 vaega ole alumini sesquioxide, silica 1 vaega,

1 vaega o le titanium dioxide,

2~3 vaega o mullites,

1~2 vaega ole sui so'o fa'atasi titanate,

6~10 vaega o lubricants,

2 ~ 3 vaega o mea fa'alanu.
