Polyvinyl chloride, PVC, ipolymer yakaumbwa nevinyl chloride monomer (VCM) muperoxide, azo compounds kana polymerization nzira yeradical polymerization pasi pechiedza nekupisa.Ethylene chloride homopolymer uye vinyl chloride copolymer system inonzi vinyl chloride resin.PVC yaimbova chigadzirwa chepurasitiki chikuru pasi rose uye chinoshandiswa zvakanyanya.Inoshandiswa zvakanyanya mukuvaka, zvigadzirwa zvemaindasitiri, zvinodiwa zvezuva nezuva, dehwe repasi, zvidhinha zvepasi, dehwe rekugadzira, pombi zvinhu, waya uye tambo, kurongedza firimu, mabhodhoro, furo zvinhu, yekuisa chisimbiso, fiber nezvimwe zvinhu.Zvinoenderana neyakasiyana chiyero chekushandisa, PVC inogona kukamurwa kuita: general mhando PVC resin, yakakwirira polymerization PVC resin, muchinjiko-yakabatana PVC resin.General type PVC resin inoumbwa ne polymerization yevinyl chloride monomer pasi pechiito cheinitiator;yakakwira polymerization PVC resin inoreva iyo polymer ye polymerization system;uye crosslinked PVC resin inoumbwa ne crosslinking agent ine diene uye polyene muvinyl chloride monomer polymerization system.Zvinoenderana nekutora nzira ye ethylene chloride monomer, inogona kukamurwa kuita calcium carbide nzira, ethylene nzira uye kunze kwenyika (EDC, VCM) monomer nzira (ethylene nzira uye kunze kwenyika monomer nzira inogara ichinzi ethylene nzira).Maererano ne polymerization nzira, PVC inogona kukamurwa muzvikamu zvina: kumiswa nzira PVC, emulsion nzira PVC, yakawanda nzira PVC, mhinduro nzira PVC.Suspension PVC ndiyo goho rakakura, rinoverengera 80% yePVC yese.Kusimwa nzira yePVC yakakamurwa kuva mienzaniso mitanhatu: XS-1, XS-2..., XS-6;XJ-1, XJ-2..., XJ-6.Zvinorehwa nebhii rega rega mumuenzaniso: X-kumiswa nzira;S-yakasununguka mhando;J-tight type.Maererano nezvinyorwa zveplasticizer, PVC plastiki ene plastiki inowanzoparadzaniswa kuva: hapana plasticizer PVC, plasticizer content is 0;yakaoma PVC, plasticizer content iri pasi pe10%;semi-yakaoma PVC, plasticizer zvirimo 10-30%;nyoro PVC, plasticizer zviri 30-70%;polyvinyl
