Yintoni i-PVC?

I-PVClifutshane igama elithi polyvinyl chloride, kwaye inkangeleko yalo yipowder emhlophe. I-PVC yenye yeeplastiki ezintlanu eziqhelekileyo ehlabathini. Isetyenziswa kakhulu kwihlabathi liphela, ingakumbi kwicandelo lokwakha. Kukho iintlobo ezininzi ze-PVC. Ngokwemvelaphi yezinto ezisetyenzisiweyo, inokwahlulwahlulwa ibeikharbhide yecalciumindlela kunyeindlela ye-ethylene. Izinto ezisetyenziswa kwindlela ye-calcium carbide zivela kakhulu kumalahle nakwityuwa. Izinto ezisetyenziswa kwinkqubo ye-ethylene zivela kakhulu kwi-oyile ekrwada. Ngokweenkqubo ezahlukeneyo zemveliso, inokwahlulwa ibe yindlela yokumiswa kunye nendlela yokufakelwa. I-PVC esetyenziswa kwintsimi yokwakha yindlela yokumiswa, kwaye i-PVC esetyenziswa kwintsimi yesikhumba yindlela yokufakelwa. I-Suspension PVC isetyenziswa kakhulu ukuvelisa: i-PVCimibhobho, I-PVCiiprofayili, iifilimu zePVC, izihlangu zePVC, iingcingo kunye neentambo zePVC, umgangatho wePVC njalo njalo. I-Emulsion PVC isetyenziselwa kakhulu ukuvelisa: iiglavu zePVC, ulusu lokwenziwa lwePVC, iphepha lodonga lePVC, iithoyi zePVC, njl.
Itekhnoloji yemveliso yePVC ihlala ivela eYurophu, eMelika naseJapan. Umthamo wemveliso yePVC kwihlabathi liphela ufikelele kwiitoni ezingama-60 ezigidi, kwaye iTshayina ithatha isiqingatha sehlabathi. ETshayina, i-80% yePVC iveliswa yinkqubo ye-calcium carbide kwaye i-20% iveliswa yinkqubo ye-ethylene, kuba iTshayina ibisoloko ililizwe elinamalahle amaninzi kunye neoyile encinci.
