Polyvinyl chloride, lus Askiv rau luv luv (Polyvinyl chloride), yog tus pib ua vinyl chloride monomer (VCM) hauv peroxides, Azov tebchaw, lossis lwm yam lossis hauv qab qhov kev txiav txim ntawm lub teeb thiab kub ua raws li cov tshuab ntawm dawb radical polymerization Polymerized polymer. Vinyl chloride homo-polymers thiab vinyl chloride co-polymers yog hu ua kev vinyl chloride resins.
PVC yog amorphous dawb hmoov nrog lub teeb me me ntawm kev sib tw, tus txheeb ze ntom ntim ntawm kwv yees li ntawm 1.4, lub khob hloov pauv ntawm 77 ~ 90 ° C, thiab qhov ua kom kub siab txog li 170 ° C. Kev kub ntxhov tsis zoo rau lub teeb thiab kub, saum toj no 100 ° C lossis Tom qab lub hnub ntev ntev tiv thaiv lub hnub, nws yuav decompose los ua cov tshuaj hydrogen chloride, thiab txuas ntxiv ua rau catalyzes decomposition, ua rau muaj kev cuam tshuam, thiab cov khoom siv lub cev thiab lub cev kuj txo qis sai. Hauv kev siv tswv yim, tus stabilizers yuav tsum tau ntxiv los txhim kho qhov ruaj ntseg kom sov thiab teeb.
Lub phaus molecular ntawm kev lag luam tsim PVC feem ntau nyob hauv thaj tsam ntawm 50,000 txog 110,000. Nws muaj cov perversity loj, thiab qhov hnyav molecular nce nrog qhov txo qis ntawm qhov polymerization kub. Yog tias tsis muaj qhov chaw tso zis, nws pib muag ntawm 80 txog 85 ° C thiab ua viscosity ntawm 130 ° C., 160 ~ 180 ℃ pib hloov mus rau khov dej ntws hauv lub xeev; muaj cov cuab yeej zoo txhua yam, tensile lub zog ntawm txog 60MPa, cuam tshuam lub zog ntawm 5 ~ 10kJ / m 2 ; muaj lub zog dielectric zoo nkauj.
PVC yog ib zaug hauv ntiaj teb qhov loj tshaj plaws cov hom phiaj yas, thiab nws tau siv dav. Nws yog dav siv hauv cov ntaub ntawv hauv tsev, cov khoom lag luam, cov khoom siv niaj hnub, tawv ntoo hauv pem teb, cov nplais hauv av, tawv tawv, cov kav dej, cov xov hlau thiab cov xaim hluav taws xob, ntim zaj duab xis, lub raj mis, cov khoom siv foaming, cov khoom sib khi, cov fibers, thiab lwm yam.
