Kumuntu obukele nje, kukhona umehluko omncane phakathi kwepayipi le-PVC nepayipi le-UPVC.Zombili zingamapayipi epulasitiki asetshenziswa kakhulu ekwakheni.Ngale kokufana okukha phezulu, lezi zinhlobo ezimbili zamapayipi akhiwe ngendlela ehlukile futhi ngaleyo ndlela anezakhiwo ezihlukene kanye nezicelo ezihluke kancane ekwakheni nakwezinye izinqubo zezimboni futhi ukuchayeka emsebenzini wokukhanda kumapayipi epulasitiki ku-PVC kune-UPVC.
Ukukhiqiza
I-PVC ne-UPVC zenziwe kakhulu ngezinto ezifanayo.I-Polyvinylchloride iyi-polymer engashiswa futhi ibunjwe ukuze idale izinhlanganisela eziqinile, eziqinile njengamapayipi.Ngenxa yezakhiwo zayo eziqinile lapho sesakhiwe, abakhiqizi bavame ukuhlanganisa ama-polymers epulasitiki engeziwe abe yi-PVC.Lawa ma-polymers enza ipayipi le-PVC ligobe kakhudlwana futhi, ngokuvamile, kulula ukusebenza ngalo kunalapho lihlala lingenapulasitiki.Lawo ma-plastizing agents ashiywa ngaphandle lapho kukhiqizwa i-UPVC—igama lifushane elithi i-polyvinylchloride engafakwanga—ecishe iqine njengepayipi lensimbi elicijile.
Ukuphatha
Ngezinjongo zokufakwa, ipayipi le-PVC nele-UPVC ngokuvamile liphathwa ngendlela efanayo.Zombili zingasikwa kalula ngama-hack saw blades noma amathuluzi kagesi aklanyelwe ukusika ipayipi le-PVC futhi womabili ahlanganiswa kusetshenziswa amakhompiyutha e-gluing kunokuba ahlanganiswe.Ngenxa yokuthi ipayipi le-UPVC alinawo ama-polymers enza i-PVC igobe kancane, kufanele lisikwe lilingane kahle ngosayizi ngoba alikuvumeli ukupha.
Izinhlelo zokusebenza
Ipayipi le-PVC lisetshenziswa esikhundleni samapayipi ethusi ne-aluminium emanzini angaphuzwayo, esikhundleni samapayipi ensimbi emigqeni yemfucuza, amasistimu okunisela kanye nezinhlelo zokujikeleza kwamachibi.Ngenxa yokuthi imelana nokugqwala kanye nokuwohloka okuvela emithonjeni yebhayoloji, iwumkhiqizo oqinile ongawusebenzisa ezinhlelweni zamapayipi amanzi.Isikwa kalula futhi amalunga ayo awadingi ukusoda, ukuqiniswa ngeglue esikhundleni salokho, futhi inikeza inani elincane lokupha lapho amapayipi angalingani kahle, ngakho-ke ipayipi le-PVC livame ukukhethwa ngabasebenza ngezandla njengendlela esebenziseka kalula esikhundleni sensimbi. ukubhobhoza.
Ukusetshenziswa kwe-UPVC akusandile kangako ekufakweni kwamapayipi eMelika, nakuba ukuqina kwayo kuye kwayisiza ukuthi ibe yimpahla yokuzikhethela emigqeni yokukhipha indle, ithathe indawo yepayipi lensimbi.Ibuye isetshenziswe njalo ekukhiqizeni amasistimu okukhipha amanzi angaphandle njengamanzi emvula.
Okuwukuphela kohlobo lwamapayipi epulasitiki okufanele asetshenziselwe ukudluliswa kwamanzi okuphuza ipayipi le-cPVC.
