Ukusetyenzwa kweekhoyili ezenziwe ngegalvanized

Inkcazelo emfutshane:

I-galvanizing ibhekiselele kwitekhnoloji yonyango lomphezulu wokubeka umaleko we-zinc kumphezulu wesinyithi, i-alloy okanye ezinye izinto zobuhle kunye nokuthintela umhlwa.Eyona ndlela iphambili yi-galvanizing eshushu.

I-Zinc inyibilika ngokulula kwi-asidi kunye ne-alkali, ngoko ibizwa ngokuba yintsimbi ye-amphoteric.I-Zinc ayitshintshi ngokukhawuleza emoyeni owomileyo.Kumoya omanzi, ifilimu ye-zinc carbonate edibeneyo iya kwenziwa kwi-zinc surface.Kwi-atmosfera equlethe i-sulfur dioxide, i-hydrogen sulfide kunye ne-atmosphere yaselwandle, ukuxhathisa ukubola kwe-zinc kubi, ngakumbi kwi-atmosfera equkethe i-asidi ye-organic kubushushu obuphezulu kunye nokufuma, i-zinc yokugqoka ilula kakhulu ukuba i-corroded.Umgangatho oqhelekileyo we-electrode ye-zinc yi-0.76v.Kwi-substrate yensimbi, ukugquma kwe-zinc kungokwe-anodic coating.Isetyenziselwa ikakhulu ukukhusela ukubola kwentsimbi.Ukusebenza kwayo okukhuselekileyo kuhambelana ngokusondeleyo nobukhulu bokugquma.Iipropathi ezikhuselayo kunye nezihombise i-zinc coating inokuphuculwa kakhulu emva kokudlula, ukudaya okanye ukugquma nge-agent ekhuselayo yokukhanya.
