Yam ntxwv
PVC yas "polyvinyl chloride yas", nws yog cov hmoov dawb, cov khoom lag luam yog tsim los ntawm polymerization ntawm vinyl chloride monomer, thiab ntxiv lwm cov ntsiab lus los txhim kho cov khoom kub, toughness thiab ductility, nws yog ib qho ntawm cov thermoplastic.cov khoom xim blightly, Anti-corrosion, muaj zog thiab ruaj khov, Nws kuj tseem tua hluav taws (Nplaim retardant tus nqi ≥40), tshuaj lom neeg tsis kam (sulfuric acid concentration 90%, Nitric acid concentration 60% thiab Sodium hydroxide concertration 20%), zoo heev mechanical zog thiab zoo rwb thaiv tsev. Tab sis lub teeb tsis kam thiab kub tsis kam yog me ntsis phem (softening point 80 ℃, yog temperture ntau tshaj 130 ℃, xim yuav hloov thiab tuaj tawm HCI), Yog li peb yuav tsum ntxiv stabilizer los txhim kho lub teeb thiab tshav kub thaum siv.
