PVC yog ib tug polymer tsim los ntawm dawb radical polymerization ntawm vinyl chloride monomers (VCM) nrog cov pib xws li peroxide thiab azo tebchaw los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab kub.
PVC siv los ua lub ntiaj teb cov khoom loj tshaj plaws ntawm cov yas yas, yog ib qho ntawm tsib cov yas yas (PE polyethylene, PP polypropylene, PVC polyvinyl chloride, PS polystyrene, ABS). , pem teb tawv, pem teb pobzeb, tawv tawv, yeeb nkab, xaim thiab cable, ntim zaj duab xis, lub raj mis, cov ntaub ntawv ua npuas ncauj, cov ntaub ntawv sealing, fibers thiab lwm yam yog dav siv.
PVC tau pom thaum ntxov li xyoo 1835 hauv Tebchaws Meskas.PVC yog industrialized nyob rau hauv thaum ntxov 1930s.Vim li cas xyoo 1930s, rau ib tug ntev lub sij hawm, PVC ntau lawm tau nyob rau hauv thawj qhov chaw nyob rau hauv lub ntiaj teb no cov yas noj.
Raws li qhov sib txawv ntawm daim ntawv thov, PVC tuaj yeem muab faib ua: dav PVC resin, siab polymerization degree PVC resin, crosslinked PVC resin.Raws li cov txheej txheem polymerization, PVC tuaj yeem muab faib ua plaub pawg: raug tshem tawm PVC, emulsion PVC, bulk PVC, daws PVC.
Polyvinyl chloride muaj qhov zoo ntawm cov nplaim hluav taws kub (nplaim retardant tus nqi ntau dua 40), cov tshuaj tiv thaiv siab (ua haujlwm rau cov concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid thiab 20% sodium hydroxide), zoo mechanical zog thiab hluav taws xob rwb thaiv tsev. .
Los ntawm 2016 txog 2020, thoob ntiaj teb PVC ntau lawm tau nce siab. Raws li Bloomberg cov ntaub ntawv txheeb cais, Tuam Tshoj cov khoom siv PVC suav nrog 42% ntawm kev tsim khoom thoob ntiaj teb, raws li qhov kev tsim tawm thoob ntiaj teb PVC yog kwv yees li 54.31 lab tons hauv 2020.
Nyob rau hauv xyoo tas los no, kev siv ntawm PVC kev lag luam tau loj hlob tsis tu ncua.Raws li cov xwm txheej uas cov khoom siv hauv tsev PVC muaj peev xwm thiab ntim ntim tsis tau nce ntau, cov ntaub ntawv kev loj hlob ntawm kev pom tseeb yog ntau qhov tshwm sim ntawm kev nthuav dav ntawm kev thov nruj tom qab kev txhim kho kev sib raug zoo ntawm cov khoom siv thiab kev xav tau.In 2018, pom meej noj ethylene nyob rau hauv Suav huab cua yog 889 lab tons, nce los ntawm 1.18 lab tons los yog 6.66% piv nrog rau xyoo tas los.Ntawm tag nrho, peb lub peev xwm ntau lawm deb tshaj qhov xav tau, thiab kev siv tus nqi ntawm cov khoom muaj peev xwm tsis siab.
