Polyvinyl chloride (Polyvinyl chloride), English abbreviation PVC, yog ib tug polymer ntawm vinyl chloride monomer (VCM) polymerized los ntawm peroxide, azo compound thiab lwm yam pib los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab kub raws li lub mechanism ntawm dawb radical polymerization..Vinyl chloride homopolymers thiab vinyl chloride copolymer yog sau ua ke hu ua vinyl chloride resins.
PVC yog cov hmoov dawb nrog cov qauv amorphous nrog me me ntawm cov ceg.Cov iav hloov pauv kub yog 77 ~ 90 ° C, thiab nws pib decompose ntawm li 170 ° C.Lub stability rau lub teeb thiab cua sov yog tsis zoo.Tshaj li 100 ° C los yog tom qab lub hnub ci ntev ntev, nws yuav decomposes los tsim hydrogen chloride, thiab ntxiv autocatalytic decomposition, ua rau discoloration thiab poob sai ntawm lub cev thiab txhua yam khoom.Hauv kev siv cov tswv yim, stabilizers yuav tsum tau ntxiv los txhim kho kev ruaj ntseg rau cov cua sov thiab lub teeb.
Qhov hnyav molecular ntawm industrially ua PVC yog feem ntau nyob rau hauv thaj tsam ntawm 50,000 mus rau 110,000.Nws muaj ib tug loj polydispersity.Qhov hnyav molecular nce nrog qhov txo qis ntawm qhov kub ntawm polymerization., 160 ~ 180 ℃ pib hloov mus rau hauv lub xeev viscous ntws;zoo txhua yam khoom, tensile lub zog ntawm txog 60MPa, cuam tshuam lub zog ntawm 5 ~ 10kJ / m2;zoo heev dielectric zog.
PVC yog ib lub hom phiaj loj tshaj plaws hauv lub ntiaj teb, thiab nws tau siv dav.Nws yog dav siv hauv cov khoom siv hauv tsev, cov khoom lag luam, cov khoom siv niaj hnub, cov tawv tawv hauv pem teb, cov vuas hauv pem teb, tawv tawv, cov kav dej, cov xov hlau thiab cov cables, ntim cov yeeb yaj kiab, lub raj mis, cov ntaub ntawv ua npuas ncauj, cov ntaub ntawv sealing, fibers, thiab lwm yam.
