Polyvinyl chloride yeeb nkab, kuj thov pvc yeeb nkab, yog cov tubing uas thermal plasticity siab polymer uas tsim los ntawm polymerization ntawm vinyl choride monomer yog tsim, siv polyvinyl chloride (PVC) RESINS raws li cov khoom siv tseem ceeb, ntxiv cov tshuaj tiv thaiv tsim nyog, cov khoom kho tus neeg sawv cev. thiab lwm yam, cov khoom tsim los ntawm cov txheej txheem xws li kev sib tov, calendering, nqus formings.

PVC yeeb nkab tsis kam tiv thaiv corrosion yog muaj zog, nws yog kev sib txuas kom yooj yim, PVC muaj zog tiv taus oxygenant, txo tus neeg sawv cev thiab muaj zog acid.Tab sis nws tuaj yeem corroded thiab lub sijhawm tseem siv tsis tau tiv tauj nrog cov ntxhiab hydrocarbon, chlorinated hydrocarbon li vitriol. roj, concentrated nitric acid los ntawm ntom oxidizing acid.

Tab sis, pvc yeeb nkab, tshwj xeeb tshaj yog UPVC yeeb nkab kuj toheat yog tsis zoo, thiab ib puag ncig tensile zog poob ntau tshaj 60 ℃, thiab nyob rau hauv tsis tshua muaj kub ib puag ncig, Vybak dej tua kuj yuav cuam tshuam kev poob siab. rupture;Tsis tas li ntawd, qhov kev ua tau zoo uas pvc yeeb nkab tiv thaiv kev poob siab kuj tsis zoo.

Ib hom siab tenacity polychloroethylene kav, yuav tsum tau ua los ntawm cov ntsiab lus ntawm qhov hnyav hauv qab no:

100 ~ 150 qhov chaw ntawm polyvinyl chloride (PVC) RESINS,

20 ~ 30 qhov chaw ntawm chlorinated polyvinyl chloride resins,

6 ~ 8 qhov chaw ntawm acrylic resins,

2 ~ 4 ntu ntawm Poly (Trimethylene Terephthalate),

3 ~ 6 qhov chaw ntawm urethane,

10 ~ 15 qhov chaw, styrene-butadiene roj hmab (SBR),

3-6 qhov chaw ntawm cov txiv neej,

1 ~ 2 feem ntawm methyl methacrylate,

1 ~ 2 feem ntawm dibasic lead phosphite,

2 ~ 4 qhov chaw ntawm silicon carbide whiskers,

1 ~ 2 ntu, iav fiber,

2 ~ 3 qhov chaw ntawm polymeric amide,

2-4 feem ntawm diphenyl phosphites,

2 ~ 3 qhov chaw ntawm stabilizers,

2 ~ 6 qhov chaw ntawm Chlorinated Polypropylene III acid-butadiene-styrene copolymer,

1 ~ 2 feem ntawm cov tshuaj tiv thaiv kab mob,

1 feem ntawm aluminium sesquioxide, silica 1 feem,

1 feem ntawm titanium dioxide,

2-3 feem ntawm mullites,

1 ~ 2 feem ntawm titanate coupling tus neeg sawv cev,

6 ~ 10 qhov chaw ntawm lubricants,

2 ~ 3 qhov chaw ntawm cov ntaub ntawv tinting.
