Cov khoom siv yas sib txawv yog tsim los ntawm hom resin siv. Hais dav dav, lawv tuaj yeem muab faib ua polyvinyl chloride (PVC), polyethylene (PE), thiab polypropylene (PP).
Polyvinyl Chloride (PVC)
PVC, abbreviated li PVC, yog ib tug polymer synthesized los ntawm vinyl chloride monomer nyob rau hauv qhov kev txiav txim ntawm peroxides thiab azo tebchaw. Nws tseem hu ua vinyl chloride resin. Nws muaj kev siv dav heev.
Kev faib tawm: PVC tuaj yeem muab faib ua cov ntawv PVC tawv, cov ntawv hloov pauv PVC (cov yob), cov ntawv hollow PVC, thiab cov ntawv foamed PVC.
Rigid PVC cov ntawv feem ntau yog siv rau kev sim cov khoom siv, cov khoom hnyav, thiab cov ntaub qhwv. PVC cov ntaub ntawv yooj yim (rolls) yog siv rau hauv tshuaj, electroplating, electrolytic cell, acid thiab alkali pas dej ua ke linings, rwb thaiv tsev txheej, tsheb ciav hlau thiab automotive interiors thiab auxiliary cov ntaub ntawv, thiab lwm yam.
