I-PPGIisifinyezo se-PrePainted Galvanized, okuyikhoyili yensimbi epeyintwe ngaphambili eyi-ppgi.Ngokuvamile ibhekisela kuKhoyili we-PPGI (ikhoyili enamathayela anemibala), Ishidi le-PPGI (ishidi elakhiwe ngombala) kanye neminye imikhiqizo yensimbi.I-PPGLimele ishidi lensimbi eliboshwe nge-galvalume.
Ukufakwa kombala ophehliwe kanye nokufakwa kombala we-aluminium zinc kuwubuchwepheshe obubili obuhlukene bokuhlanganisa, futhi kunomehluko othile ekusetshenzisweni nasekusebenzeni.Uma ufuna ukwazi umehluko phakathi kwalokhu kokubili, qhubeka ufunda.
Ukufakwa kombala ophehliwe ubuchwepheshe obusebenzisa i-zinc njengesisekelo futhi bumboze ungqimba lwemibala enemibala endaweni ye-zinc.Ifanele izimo zemvelo ezilula.I-Galvalume color coating ubuchwepheshe obusebenzisa i-aluminium zinc njengesisekelo futhi igqoke ungqimba lwe-pigments enemibala ebusweni be-aluminium zinc.Inokumelana nokugqwala okungcono futhi ifanele izimo zemvelo ezinzima.
Ubuhle bekhoyili yensimbi ye-galvalume ependwe kusengaphambili ukuthi i-aluminium-zinc yayo inokumelana nokugqwala okuhle kanye ne-conductivity, futhi ingamelana ngokuphumelelayo nezinto zokugqwala ezifana nama-asidi, ama-alkali, nosawoti.Izibala zombala zikapende othathiwe zinokumelana nokugqwala okungcono futhi akulula ukufiphala.Kodwa-ke, intengo yokugqoka umbala othayelayo iphakeme kakhulu.
Inzuzo ye-ppgi galvanized steel coil ukuhlukahluka kombala wayo, umbala ungalungiswa kuye ngezidingo, futhi intengo yayo iphansi.Kodwa-ke, i-pigments yombala kapende othathiwe inganikeza ukumelana nokugqwala okulinganiselwe.Ngaphansi kwezimo zemvelo ezinzima, umbala ungase uphele futhi awukwazi ukunikeza ukumelana nokugqwala okuhle.
Ngakho-ke, lapho ukhetha i-PPGI ne-PPGL, udinga ukucabangela indawo yokusetshenziswa, izimo zemvelo kanye nezidingo zamakhasimende.Uma idinga ukusetshenziswa ngaphansi kwezimo zemvelo ezithambile, inezidingo eziphakeme zombala futhi izwela intengo, khona-ke ukunamathela kombala othayela kuyisinqumo esihle.Kodwa-ke, uma idinga ukusetshenziswa ezimweni ezinzima zemvelo futhi idinga ukuhlinzeka ngokumelana nokugqwala okuhle, khona-ke ukunamathela kombala ogqamile kuyisinqumo esingcono.
Kukhona futhi umehluko othile ohlelweni lokukhiqiza lwe-PPGI ne-PPGL.Inqubo yokukhiqiza yokuhlanganisa umbala wamapulangwe ilula, inqubo ayiyona inkimbinkimbi, futhi umjikelezo wokukhiqiza umfushane.Kodwa-ke, inqubo yokukhiqiza yokufaka umbala othayelayo iyinkimbinkimbi, inqubo inzima, futhi umjikelezo wokukhiqiza mude.
Okokugcina, kufanele kuqashelwe ukuthi inani kanye nokusebenza kwezindleko kwe-PPGI ne-PPGL kuhlukile.Amakhasimende adinga ukukala okuhle nokubi ngokwezidingo zawo lapho ekhetha ukuqinisekisa ukuthi kukhethwa ubuchwepheshe bokugqoka obufaneleka kakhulu.
Ngamafuphi, i-PPGI ne-PPGL ubuchwepheshe bokuhlanganisa obubili obuhlukene, obunomehluko ekusetshenzisweni nasekusebenzeni.Ibuphi ubuchwepheshe bokuhlanganisa okufanele busetshenziswe budinga ukunqunywa ngokusekelwe endaweni yokusetshenziswa, izimo zemvelo, kanye nezidingo zamakhasimende.
