PVC Bar Khoom siv

PVC yog cov lus luv los ntawm polyvinyl chloride, lub ntsiab tivthaiv yog PVC, qaim xim, tiv thaiv corrosion, muaj zog thiab ruaj khov. Thaum lub sijhawm txheej txheem ntau lawm, plasticizer, tus neeg sawv cev tiv thaiv kev laus thiab lwm cov ntaub ntawv pabcuam ntxiv, uas ua kom cov tshav kub tsis kam, ua kom tawv thiab ductility ntawm cov khoom. Cov khoom siv PVC yog ib hom ntawm cov khoom siv tsis siv lead ua, yog ib qho ntawm cov ntaub ntawv tshaj plaws yas. Nws tsis yooj yim mus hlawv, siab lub zog, kev hloov huab cua tsis kam thiab zoo heev geometric stability. Nws muaj cov muaj zog tiv thaiv zoo rau txo tus neeg sawv cev thiab muaj zog acid. Lub shrinkage tus nqi ntawm PVC cov khoom lag luam yog qhov tsawg heev, feem ntau 0.2-0.6%.
