Iingubo zeZinc zibonelela ngokumelana nokugqwala okuqinileyo, zandisa ubomi bentsimbi kwiindawo ezinoburhalarhume ngokuphindwe ka-20 xa kuthelekiswa nentsimbi engagqunywanga. Iziseko zentsimbi—iibhulorho, iipali zombane, ii-guardrails—zixhomekeke kwintsimbi egqunywe zinc ukuze kuncitshiswe ukugcinwa kwayo kunye nexesha elide lenkonzo. Kubavelisi, iingenelo zentsimbi egqunywe zinc zihlala ixesha elide lemveliso kunye neendleko ezincitshisiweyo zobomi bokwakha kunye neemoto.
Ukulinganiswa koBungqingqwa bokugquma kwiNsimbi eQokelelweyo yeZinc
*
Ubunjineli bufuna ibhalansi yokunamathela kwengubo, ukugungqa, kunye nobukhulu obukhuselayo; iileya ezixineneyo zinokuqhekeka ngexesha lokubumba, ngelixa iifilimu ezincinci zisenokungahlangabezani nemigangatho yobukhulu bengubo ye-zinc yokusebenza kwesakhiwo. I-hot-dip galvanizing idla ngokufikelela kwiileya eziphakathi kwe-45–100+ µm, inika umqobo ophezulu kunye nokhuseleko lwe-cathodic. I-galvanizing eqhubekayo ivelisa iileya ze-zinc ezifanayo ngokuchanekileyo, ezihlala ziyi-7–25 µm, nto leyo evumela ukwakheka okuphezulu kunye nokucutshungulwa ngokukhawuleza.
Iziphumo zenkqubo yokugquma i-zinc zixhomekeke kulwakhiwo lwentsimbi, nto leyo echaphazela ukudityaniswa kwe-zinc kunye nokufana kobukhulu be-coating. Amanqanaba e-silicon kunye ne-phosphorus kwintsimbi anokubangela ukuqokelelwa kwe-zinc okungaqhelekanga (“isiphumo seSandelin”).
