Yintoni iPVC?

I-PVCimfutshane kwipolyvinyl chloride, kwaye inkangeleko yayo ingumgubo omhlophe. IPVC yenye yeeplastiki ezintlanu jikelele ehlabathini. Isetyenziswa ngokubanzi kwihlabathi, ngakumbi kwintsimi yokwakha. Kukho iintlobo ezininzi zePVC. Ngokomthombo wezinto eziluhlaza, inokwahlulwa ibecalcium carbideindlela kunyeindlela ethylene. Izinto ezikrwada zendlela ye-calcium carbide zivela ikakhulu kumalahle kunye netyuwa. Imathiriyeli ekrwada yenkqubo ye-ethylene ikakhulu ivela kwioyile ekrwada. Ngokweenkqubo ezahlukeneyo zemveliso, inokwahlulwa ibe yindlela yokumiswa kunye nendlela ye-emulsion. I-PVC esetyenziswa kwintsimi yolwakhiwo yindlela yokunqunyanyiswa, kwaye i-PVC esetyenziswa kwintsimi yesikhumba yindlela ye-emulsion. Ukumiswa PVC zisetyenziswa ikakhulu ukuvelisa: PVCimibhobhoPVC,iiprofayili, iifilimu zePVC, izihlangu zePVC, iingcingo zePVC kunye neentambo, imigangatho yePVC njalo njalo. Emulsion PVC zisetyenziswa ikakhulu ukuvelisa: iiglavu PVC, PVC yesikhumba eyenziweyo, PVC lodonga, PVC zokudlala, njl.
Iteknoloji yemveliso yePVC ihlala ivela eYurophu, eU.SA naseJapan. Umthamo wemveliso wePVC wehlabathi ufikelele kwi-60 yezigidi zeetoni, kwaye iTshayina yabalelwa kwisiqingatha sehlabathi. E-China, i-80% ye-PVC iveliswa yinkqubo ye-calcium carbide kunye ne-20% ngenkqubo ye-ethylene, kuba i-China ibisoloko ililizwe elinamalahle amaninzi kunye neoli encinci.
