Kutheni i-galvanized sheet irusa?
I-zinc i-corrod ngokuqhelekileyo, ngaphandle koko ithetha ukuba i-zinc plate ayihlambulukanga kwaye iqulethe ukungcola, njengentsimbi.I-Zinc ikhusela ezinye iintsimbi.Ukwaleka kwe-zinc engalinganiyo kuya kuveza isinyithi ngaphakathi kwaye kubangele ukubola.Okanye udibane ngokungazi nezinye iintsimbi ukwenza umhlwa kwikhemikhali.
Iphepha le-galvanized lingagqwala, kodwa i-galvanized layer i-oxidized kuqala ukukhusela umbhobho wensimbi kwi-rust, kwaye ubomi bayo benkonzo bude.Ngaphantsi kweemeko zendalo, i-chrome-plated layer ayiyi kusabela nge-oksijini, i-carbon dioxide kunye namanzi emoyeni, kwaye ayiyi kutshatyalaliswa yi-acids ebuthakathaka kunye ne-alkali.Impembelelo yayo yokuchasa ngokuqinisekileyo ingcono.
Iphepha elenziwe ngegalati aliyi kugqwala kwindawo yesiqhelo, kwaye lingaphoswa ngenxa yogcino olungafanelekanga, ukukhuhla kunye nokungqubana, ukungena kwamanzi kunye nokufuthwa komphunga.Isizathu sokuba i-galvanized sheet irusa kukuba i-zinc igruthwa ngokuqhelekileyo ukukhusela ezinye iintsimbi.Ngaphandle koko, i-zinc plate ayihlambulukanga kwaye iqulethe ukungcola, njengentsimbi.Okanye i-zinc coating ayilingani, iveza isinyithi ngaphakathi, ibangela ukubola, okanye idibane ngokungaziyo nezinye izinyithi, yenze ukubola kweekhemikhali.
