Njengomkhiqizo wokuvala ojwayelekile futhi ongabizi kakhulu emndenini wokuvala irabha, imichilo yokuvala irabha ye-PVC isetshenziswa kabanzi ekuhlobiseni izinto zokwakha, iminyango namafasitela ajwayelekile, ifenisha, izinto zikagesi kanye nezimo zokuvala imishini yansuku zonke, ithatha isikhundla esiphambili emakethe yokuvala ephakathi nephansi. Ngobuchwepheshe bokukhiqiza obuvuthiwe kanye nekhwalithi yomkhiqizo ezinzile, imichilo yokuvala i-PVC ibe yisinqumo esithandwayo samaphrojekthi amaningi okuhlobisa ajwayelekile kanye nezimboni ezincane neziphakathi zokukhiqiza imishini ngenxa yokusebenza kwazo okubiza kakhulu, ukucubungula okulula kanye nezitayela ezicebile.
Umugqa wokuvala irabha we-PVC wenziwe ngezinto ze-polyvinyl chloride eziguquliwe, ezihlanganiswe ne-softener, i-ejenti yokulwa nokuguga nezinye izinto ezisizayo, ezinokuguquguquka okuhle, ukumelana nokuguguleka kanye nokumelana nokugoba. Umkhiqizo ulula, kulula ukuwusika nokuwufaka, futhi ungaguqulwa ukuze uvumelane nezikhala ezahlukene ezingajwayelekile. Ngokungafani nezinto zerabha ezisebenza kahle njenge-EPDM kanye nerabha ye-silicone, imichilo yokuvala i-PVC inokusebenza okulingene kanye namanani angabizi kakhulu, angahlangabezana ngokugcwele nezidingo zokuvala zansuku zonke zezindawo zangaphakathi ngaphandle kwezidingo ezinamandla zokumelana nesimo sezulu. Ifaneleka kakhulu iminyango yokhuni yangaphakathi, iminyango yamakhabethe, izikhala zekhabethe, iminyango namafasitela e-aluminium alloy yangaphakathi, kanye nokuvalwa kwemishini kagesi yasekhaya.
Ngokuphathelene nokuhlukaniswa komkhiqizo, imichilo yokuvala ye-PVC ihlukaniswe yaba yi-PVC esobala, i-PVC engacwebezeli, i-PVC enegwebu kanye ne-PVC ehlanganisiwe eqinile nethambile. Imichilo yokuvala ye-PVC enegwebu inomphumela omuhle kakhulu wokuvikela umsindo kanye nemiphumela ye-buffer, enganciphisa ngempumelelo umsindo wokushayisana lapho iminyango namafasitela evaliwe futhi idlala indima ethile yokuvikela ukushayisana. Imikhiqizo ye-PVC esobala nengacwebezeli ibukeka kahle, ihambisana nezitayela ezahlukene zokuhlobisa, futhi ngeke ithinte umphumela wokuhlobisa jikelele wezakhiwo nefenisha. Umkhiqizo unamandla amahle okuvikela amanzi nothuli, okungavimbela uthuli oluncane, omiyane nomoya omanzi ukungena ekamelweni, futhi kuthuthukise ukuhlanzeka kwangaphakathi kanye nenduduzo.
Eminyakeni yamuva nje, amazinga okuvikela imvelo embonini akhuphukayo asuse imikhiqizo yendabuko ye-PVC ephansi, kanti imichilo yokuvala ye-PVC emisha eguquliwe enobungani nemvelo ifinyelela ukuthandwa okugcwele emakethe. Amafomula abuyekeziwe asusa ama-plasticizer ayingozi, angenalo iphunga, angenabo ubuthi futhi ahambisana ngokugcwele nemininingwane yokuphepha yasekhaya neyamazwe ngamazwe. Nakuba imichilo ye-PVC isala ngemuva kwemikhiqizo ye-EPDM ne-silicone ekumelaneni nokushisa okuphezulu kanye nokubekezelela ukuguga kwangaphandle, ihlangabezana kahle nezidingo zesevisi yesikhathi eside zezindawo ezivaliwe zangaphakathi. Njengoba inamandla okusebenza aphezulu kakhulu futhi ivumelana nezimo ngezindlela eziningi, imichilo yokuvala irabha ye-PVC igcina amasheya emakethe azinzile futhi ihlala iyizesekeli zokuvala ezisetshenziswa kakhulu emhlabeni wonke kumaphrojekthi okuhlobisa umphakathi emhlabeni jikelele.
