A: Ipropathi I-Polyvinyl chloride iyinhlanganisela ephezulu yamangqamuzana eyenziwe nge-vinyl chloride monomer(VCM) ene-elementi yesakhiwo njenge-CH2-CHCLn,izinga le-polymerization ngokuvamile libe ngu-590-1500. inqubo ye-polymerization, izimo zokusabela, ukwakheka kwe-reactant, izithasiselo njll.ingakhiqiza izinhlobo eziyisishiyagalombili ezihlukene zokusebenza kwe-PVC resin ihlukile.Ngokusho kokuqukethwe okuyinsalela kwe-vinyl chloride ku-polyvinyl chloride resin, ingahlukaniswa: Ibanga lezentengiselwano, ibanga lenhlanzeko yokudla kanye nebanga lesicelo sezokwelapha ngokubukeka, i-polyvinyl chloride resin iyimpushana emhlophe noma i-pellet.
B: Isicelo I-Polyvinyl chloride resin isetshenziswa kabanzi ekukhiqizeni i-polyvinyl chloride boardy leatheroid, upende kanye nama-adhesive agents, i-tec.Upende nokunamathisela .Ukuhlukaniswa ngokohlelo lokusebenza:
1.Izinto zokwakha: ezifana neshubhu le-UPVC, amapayipi e-UPVC, iphaneli kanye nezinsimbi zesigaba.
2.Izinto zokupakisha.
3.Izinto zikagesi: njengezintambo zikagesi, izintambo, amateyipu anamathelayo namabhawudi.
4.Ifenisha nezinto zokuhlobisa, njll.
5.Others: leatheroid, imikhiqizo alahlwayo yezokwelapha, upende isinqandakuvunda, njll.
