Dezincation of hot{0}} silig galvanized quusin caadi ahaan waxaa sababa cillado ka dhex interface u dhexeeya lakabka zinc iyo substrate ka. Waxaa jira dhowr sababood oo suurtagal ah:
1. Tayada dusha sare ee siliga galvanized, sida saliid xad dhaaf ah, miridhku, iyo cillado kale, waxay saameyn kartaa ku-dhejinta lakabka zinc ee substrate-ka.
2. Cilladaha sida xumbo, xumbo, godadka, iyo dildilaaca kulaylka inta lagu jiro habka galvanizing waxay sidoo kale saameyn kartaa ku-xidhka lakabka zinc ee substrate-ka.
3. Heerkul daawaynta kulaylka aan habboonayn ee siliga galvanized: Heerkulka aadka u hooseeya wuxuu saameyn karaa awoodda isku xidhka lakabka zinc, halka heerkulka aadka u sarreeya uu keeni karo dareen-celin wuxuuna saameyn ku yeelan karaa adhesion.
4. Dhumucda lakabka zinc ee aan sinnayn: Meelaha qaarkood waxa laga yaabaa inay dhaafaan heerka la cayimay, halka kuwa kalena aanay dhici karin.
5. Arrimaha deegaanka waxa kale oo ay sababi karaan delamination lakabka zinc, gaar ahaan heerkulka sare{1}, qoyaanka, iyo bay'ada daxalaysa, taas oo sii yarayn karta ku dheggan lakabka zinc.
Haddii tani ay si joogto ah u dhacdo, waxaa lagula talinayaa in la aqoonsado dhibaatada lana hagaajiyo hababka iyo qalabka ku habboon.
