Iziqinisi ze-PVC zidlala indima ebalulekile emkhakheni wokukhiqiza amapayipi nezinto zokufaka. Ziyizithasiselo zamakhemikhali ezifakwe ezintweni ezifana ne-PVC (i-Polyvinyl Chloride) ukuze kuthuthukiswe ukuzinza kokushisa kanye nokumelana nesimo sezulu, ngaleyo ndlela kuqinisekiswe ukuthi amapayipi nezinto zokufaka zihlala isikhathi eside futhi zisebenza kahle ngaphansi kwezimo zemvelo nezimo zokushisa ezahlukahlukene. Imisebenzi eyinhloko yeziqinisi ihlanganisa:
Ukumelana Nokushisa Okuthuthukisiwe:Amapayipi nezinto zokufaka zingabhekana nokushisa okuphezulu ngesikhathi sokulungiswa. Izinto zokuqinisa zivimbela ukuwohloka kwezinto, ngaleyo ndlela zandise isikhathi sokuphila kwamapayipi nezinto zokufaka ezisekelwe ku-PVC.
Ukukhuthazela Kwesimo Sezulu Okuthuthukisiwe:Iziqinisi ziqinisa ukuqina kwesimo sezulu emapayipini nasezintweni ezifakwayo, ziwavumela ukuthi abhekane nemisebe ye-UV, i-oxidation, nezinye izici zemvelo, okunciphisa umthelela wezinto zangaphandle.
Ukusebenza Kokuvimbela Okuthuthukisiwe:Iziqinisi zisiza ekulondolozeni izakhiwo zokuvikela ugesi zamapayipi kanye nezinto zokufakelwa. Lokhu kuqinisekisa ukudluliselwa kwezinto okuphephile nokungaguquguquki, kunciphisa ingozi yokuwohloka kokusebenza.
Ukulondolozwa Kwezici Zomzimba:Iziqinisi zisiza ekulondolozeni izici zomzimba zamapayipi nezinto zokufakelwa, okuhlanganisa amandla okunamathela, ukuguquguquka, kanye nokumelana nokushayisana. Lokhu kuqinisekisa ukuzinza nokuthembeka kwamapayipi nezinto zokufakelwa ngesikhathi sokusetshenziswa.
Ngamafuphi, iziqinisi zisebenza njengezinto ezibalulekile ekukhiqizweni kwamapayipi kanye nokufakwa. Ngokunikeza ukuthuthukiswa okubalulekile, ziqinisekisa ukuthi amapayipi kanye nokufakwa kuyasebenza kakhulu ezindaweni ezahlukene kanye nezicelo.
