Umzi-mveliso wediphu otshisayo wediphu: umaleko oshushu wokuntywila wediphu uqheleke ngaphezu kwe-35m, nokuya kuthi ga kuma-200m, kunye nokugqunywa kakuhle kwediphu eshushu yokugquma, ukugquma okuxineneyo kwaye akukho ziqukethwe eziphilayo.Njengoko sonke siyazi, indlela yokumelana nokugqwala kwe-atmospheric ye-zinc ibandakanya ukukhuselwa komatshini kunye nokukhuselwa kwe-electrochemical.Ngaphantsi kweemeko ze-corrosion ye-atmospheric, kukho iifilimu ezikhuselayo ze-ZnO, i-Zn (OH) i-2 kunye ne-zinc carbonate eyisiseko phezu komgangatho we-zinc, okunciphisa ukubola kwe-zinc kwinqanaba elithile.Ukuba le filimu ekhuselayo (ekwabizwa ngokuba yi-white rust) yonakele, ifilimu entsha iya kwenziwa
Umzi-mveliso wediphu otshisayo wediphu: ukuxhathisa kokutyiwa kwe-atmospheri yediphu eshushu yokugalela kwisiseko sentsimbi kubhetele kunoko kwenza i-electro galvanizing.
Umzi-mveliso wediphu otshisayo wediphu: ubungqingqwa bomaleko oshushu wediphu wentsimbi yomnatha wentsimbi bumisela ukusebenza kokuchasa ukurusa komnatha wentsimbi.Umsebenzisi unokukhetha ubukhulu be-zinc coating ephezulu okanye ephantsi kunomgangatho.Kwimesh yentsimbi ecekethekileyo enomgangatho ogudileyo kunye nobungqingqwa obungaphantsi kwe-3mm, kunzima kubavelisi be-galvanizing yediphu eshushu ukufumana i-coating eshinyeneyo kwimveliso yamashishini.Ukongezelela, ubukhulu bengubo ye-zinc engahambelani nobukhulu be-mesh yensimbi buya kuchaphazela ukunamathela phakathi kwengubo kunye ne-substrate kunye nomgangatho wokubonakala kwengubo.Ukugqithisa kakhulu kuya kukhokelela kwinkangeleko enqabileyo, ukukrazula okulula kokugqoka, kunye ne-grating yensimbi ayikwazi ukujamelana nokungqubana ngexesha lokuphatha kunye nokufakwa.Ukuba kukho izinto ezisebenzayo ezifana ne-silicon kunye ne-phosphorus kwizinto eziluhlaza ze-mesh yensimbi, kunzima ukufumana iingubo ezincinci kwimveliso yezoshishino.Oku kungenxa yokuba umxholo we-silicon kwintsimbi uchaphazela indlela yokukhula yomaleko we-alloy phakathi kwe-zinc kunye nentsimbi, eya kwenza isigaba se-zinc iron alloy layer sikhule ngokukhawuleza kwaye sijongane nomphezulu we-coating, kubangele ukurhabaxa, iMat kunye namandla okudibanisa. yokwaleka.
