Imikhiqizo ye-PVC inomthelela omkhulu futhi oyinkimbinkimbi empilweni yomuntu, futhi ingena ezimpilweni zethu zansuku zonke ngezindlela eziningi.
Okokuqala, imikhiqizo ye-PVC isetshenziswa kabanzi emikhakheni eminingi ngenxa yokuqina kwayo, ipulasitiki kanye nezindleko eziphansi, ngaleyo ndlela ithuthukisa kakhulu ukuphila komuntu. Emkhakheni wokwakha, izinto ze-PVC zisetshenziselwa ukwenza amapayipi, ama-insulators ocingo kanye nephansi, okuhlinzeka ngesisekelo esihlala isikhathi eside nesiqinile sezakhiwo zanamuhla. Emkhakheni wokupakisha, izikhwama ze-PVC neziqukathi zisinikeza izindlela eziphumelelayo zokulondoloza nokuthutha ukudla, imithi kanye neminye imikhiqizo. Emkhakheni wezokwelapha, i-PVC isetshenziselwa ukwenza ama-catheter, amagilavu nezinsimbi zokuhlinza, ehlinzeka ngokusekela okubalulekile embonini yezokwelapha.
Kodwa-ke, ukuthandwa kwemikhiqizo ye-PVC kubuye kwaletha imithelela engemihle. Izinto eziyingozi, njenge-vinyl chloride monomer nezithasiselo, zingase zikhiqizwe ngesikhathi sokukhiqizwa kwe-PVC, okungase kube ubungozi obungaba khona empilweni yomuntu kanye nemvelo.
Ngakho-ke, sidinga ukuqaphela ukuthi imikhiqizo ye-PVC inomthelela okabili empilweni yomuntu. Ngenkathi sijabulela ukunethezeka okulethwe yi-PVC, kufanele futhi sinake ubungozi bezempilo kanye nemvelo engaziletha.
