Polyvinyl chloride

I-Polyvinyl chloride, i-PVC, i-polymer eyenziwe yi-vinyl chloride monomer (VCM) kwi-peroxide, i-azo compounds okanye indlela yokwenza i-polymerization ye-radical polymerization phantsi kokukhanya kunye nobushushu.I-ethylene chloride homopolymer kunye ne-vinyl chloride copolymer inkqubo ibizwa ngokuba yi-vinyl chloride resin.I-PVC yayikhe yaba yeyona mveliso yeplastiki inkulu ehlabathini kwaye isetyenziswa ngokubanzi.Isetyenziswa ngokubanzi kwizinto zokwakha, iimveliso zoshishino, iimfuno zemihla ngemihla, isikhumba somgangatho, isitena somgangatho, isikhumba sokwenziwa, izinto zombhobho, ucingo kunye nentambo, ifilimu yokupakisha, iibhotile, izinto ze-foam, izinto zokutywina, ifayibha kunye neminye imiba.Ngokwe-scope eyahlukeneyo yesicelo, i-PVC inokwahlulwa ibe: uhlobo oluqhelekileyo lwe-PVC resin, i-polymerization ephezulu ye-PVC, i-resin ye-PVC edibeneyo.Uhlobo oluqhelekileyo lwe-PVC resin lwenziwa yi-polymerization ye-vinyl chloride monomer phantsi kwesenzo somqalisi;i-polymerization ephezulu ye-PVC ibhekisela kwi-polymer ye-polymerization system;kunye ne-resin ye-PVC edibeneyo yenziwe nge-agent edibeneyo equkethe i-diene kunye ne-polyene kwi-vinyl chloride monomer polymerization system.Ngokwendlela yokufumana i-ethylene chloride monomer, inokwahlulwa ibe yindlela ye-calcium carbide, indlela ye-ethylene kunye nokungeniswa ngaphandle (EDC, VCM) indlela ye-monomer (indlela ye-ethylene kunye nendlela ye-monomer ephuma ngaphandle ibizwa ngokuba yi-ethylene indlela).Ngokwendlela ye-polymerization, i-PVC inokwahlulwa ibe ngamacandelo amane: indlela yokumisa i-PVC, indlela ye-emulsion ye-PVC, indlela yobuninzi ye-PVC, indlela ye-PVC yesisombululo.Ukunqunyanyiswa kwePVC sesona sivuno sikhulu, sibalelwa malunga ne-80% yePVC iyonke.Indlela yokumiswa kwePVC ihlukaniswe kwiimodeli ezintandathu: XS-1, XS-2..., XS-6;XJ-1, XJ-2..., XJ-6.Intsingiselo yeleta nganye kumzekelo: Indlela yokumiswa kwe-X;Uhlobo lwe-S;Uhlobo lwe-J-tight.Ngokomxholo we-plasticizer, i-PVC yeplastiki yeplastiki ene-plastic isoloko ihlulwe ibe: akukho plasticizer PVC, umxholo we-plasticizer ngu-0;i-PVC enzima, umxholo we-plasticizer ungaphantsi kwe-10%;i-semi-hard PVC, umxholo we-plasticizer we-10-30%;i-PVC ethambileyo, umxholo we-plasticizer we-30-70%;polyvinyl
