Iyini i-PPGI?

I-PPGIipendwe ngaphambiliniothayela insimbi, eyaziwa nangokuthi insimbi evalwe ngaphambili, insimbi enamakhoyili, insimbi enombala njll., ngokuvamile ene-dip eshisayo ehlanganiswe ne-zinc substrate yensimbi.

Leli gama liyisandiso se-GI okuyisifinyezo sendabuko se-Iron Galvanized.Namuhla igama elithi GI ngokuvamile libhekisela ku-zinc emsulwa (>99%) ehlala ishisa ngokuqhubekayo, ngokuphambene nezinqubo ze-batch dip.I-PPGI ibhekisela embonini yensimbi ehlanganiswe nge-zinc yangaphambili, lapho insimbi ipendwa khona ngaphambi kokwakhiwa, ngokuphambene nomdwebo wokuthunyelwe okwenzeka ngemva kokwakhiwa.

Inqubo yokuhlanganisa insimbi yediphu eshisayo iphinde isetshenziselwe ukwenza ishidi lensimbi ikhoyili enezimbotshana ze-aluminium, noma ama-alloy coatings e-zinc/aluminium, zinc/iron kanye ne-zinc/aluminium/magnesium okungenzeka ukuthi kupendwe kwangaphambili kwasefekthri.Nakuba i-GI ngezinye izikhathi ingase isetshenziswe njengegama elihlangene lezinsimbi ezihlukahlukene ze-dip metallic coated, ngokunembile ibhekisela kuphela kunsimbi eboshwe nge-zinc.Ngokufanayo, i-PPGI ngezinye izikhathi ingase isetshenziswe njengegama elivamile lohlu lwezinsimbi ezinamekwe ngensimbi ezipendwe ngaphambili, kodwa ngokuvamile libhekisela ngokunembe kakhulu ensimbi ependwe ngaphambili ngezinki.

I-zinc coated steel substrate ye-PPGI ivamise ukukhiqizwa kulayini oqhubekayo wokwenza uthayela (CGL).I-CGL ingase ihlanganise ingxenye yokudweba ngemva kwesigaba sokwenza idiphu elishisayo, noma ngokuvamile i-metallic coil substrate esesimweni sekhoyili icutshungulwa kulayini kapende oqhubekayo (CPL).Insimbi eboshwe ngensimbi iyahlanzwa, yelashwe ngaphambili, isetshenziswe ngezendlalelo ezihlukahlukene ze-organic coatings ezingabaamapende,i-vinylukuhlakazeka, nomaama-laminates.Inqubo eqhubekayo esetshenziselwa ukufaka lezi zembatho ngokuvamile ibizwa ngokuthi I-Coil Coating.

Ngakho-ke insimbi ekhiqizwa kule nqubo iyipeyinti epeyintwe ngaphambili, echazwe ngaphambilini futhi elungele ukusetshenzwa ibe yimikhiqizo noma izingxenye eziqediwe.ukusebenzisa impahla.

Inqubo yokumboza ikhoyili ingase isetshenziselwe amanye ama-substrates afana ne-aluminium, noma i-aluminium, insimbi engagqwali noma i-alloy coated steel ngaphandle kwensimbi “ehlanzekile” evalwe nge-zinc.Kodwa-ke, insimbi "ehlanzekile" kuphela ehlanganiswe ne-zinc ebizwa ngokuthi i-PPGI.Isibonelo, i-PPGL ingase isetshenziselwe ukupenda kwangaphambili kwensimbi engu-55% yealloy-coated engu-55% (insimbi ye-GALVALUME ependwe ngaphambili)
