I-PPGIipeyintiwe kwangaphambilii-galvanised isinyithi, ekwaziwa ngokuba yintsimbi egqunywe kwangaphambili, intsimbi egqunywe nge-coil, intsimbi egqunywe ngombala njl.njl., ngokuqhelekileyo ine-substrate yentsimbi egqunywe nge-zinc eshushu.
Eli gama lisandiso se-GI esisifinyezo sendabuko seGalvanized Iron. Namhlanje igama elithi GI lidla ngokubhekisa kwi-zinc ecocekileyo (>99%) yentsimbi egqunywe yi-dip eshushu rhoqo, ngokuchaseneyo neenkqubo ze-batch dip. I-PPGI ibhekisa kwintsimbi egqunywe yi-zinc epeyintwe ngaphambili efektri, apho intsimbi ipeyintwe ngaphambi kokuba yenziwe, ngokuchaseneyo nokupeyintwa emva kokwenziwa.
Inkqubo yokugquma ngentsimbi eshushu ikwasetyenziselwa ukwenza ishiti yentsimbi kunye ne-coil ene-aluminium coating, okanye i-alloy coating ye-zinc/aluminium, i-zinc/iron kunye ne-zinc/aluminium/magnesium enokuthi ipeyintwe kwangaphambili ngumzi-mveliso. Ngelixa i-GI ngamanye amaxesha ingasetyenziswa njengegama elidibeneyo leentsimbi ezahlukeneyo ze-hot dip metallic coating, ibhekisa ngokuchanekileyo kuphela kwintsimbi egqunywe nge-zinc. Ngokufanayo, i-PPGI ngamanye amaxesha ingasetyenziswa njengegama eliqhelekileyo leentsimbi ezigqunywe ngentsimbi ezipeyintwe kwangaphambili, kodwa rhoqo ibhekisa ngokuchanekileyo kwintsimbi egqunywe nge-zinc coating.
I-substrate yentsimbi egqunywe yizinki yePPGI idla ngokuveliswa kumgca we-galvanizing oqhubekayo (CGL). I-CGL ingabandakanya icandelo lokupenda emva kwecandelo le-hot dip galvanizing, okanye ngokuqhelekileyo i-substrate egqunywe yintsimbi kwimo ye-coil icutshungulwa kumgca wepeyinti oqhubekayo owahlukileyo (CPL). Intsimbi egqunywe yintsimbi iyacocwa, ilungiswe kwangaphambili, isetyenziswe ngeengqimba ezahlukeneyo ze-organic coatings ezinokuthi zisetyenziswe.iipeyinti,i-vinylukusasazwa, okanyeiilaminateInkqubo eqhubekayo esetyenziswayo ukufaka ezi ngubo idla ngokubizwa ngokuba yiCoil Coating.
Intsimbi eveliswa ngolu hlobo kule nkqubo ipeyintwe kwangaphambili, igqityiwe kwaye ilungele ukucutshungulwa ngakumbi ibe ziimveliso ezigqityiweyo okanye izinto ezisetyenzisiweyo.
Inkqubo yokugquma ikhoyili ingasetyenziselwa ezinye izinto ezifana ne-aluminium, okanye i-aluminium, intsimbi engatyiwayo okanye intsimbi egqunywe yi-alloy ngaphandle kwentsimbi "ecocekileyo" egqunywe yi-zinc. Nangona kunjalo, yintsimbi "ecocekileyo" kuphela egqunywe yi-zinc edla ngokubizwa ngokuba yi-PPGI. Umzekelo, i-PPGL ingasetyenziselwa intsimbi egqunywe yi-alloy engu-55% Al/Zn (intsimbi ye-GALVALUME egqunywe yi-alloy) epeyintwe kwangaphambili.
