Iingqayi zeZinc kunye neHot Dip Galvanizing: Ngaba iZinc Iza kuCorrode intsimbi yeGalvanized?

I-Hot dip galvanizing yindlela esetyenziswa ngokubanzi yokukhusela intsimbi kwi-corrosion. Intywilisela intsimbi kwindawo yokuhlambela ye-zinc etyhidiweyo, yenza uluhlu olukhuselayo phezu kwentsimbi. Le nkqubo idla ngokubizwa ngokuba yi-aimbiza yezinckuba kubandakanya ukuntywiliselwa kwentsimbi kwimbiza yezinki etyhidiweyo. Isiphumo sentsimbi ye-galvanized yaziwa ngokuhlala kwayo kunye nokuxhathisa ukubola, okwenza kube lukhetho oludumileyo kwizicelo ezininzi, ukusuka kulwakhiwo ukuya kwimveliso yeemoto.

Umbuzo oqhelekileyo onxulumeneeshushu-dip galvanizingingaba i-zinc coating iya kugqwalisa intsimbi yegalvanized ekuhambeni kwexesha. Ukusombulula le ngxaki, kubalulekile ukuqonda iipropati ze-zinc kunye nendlela abadibana ngayo ne-substrate yensimbi.

Iimbiza zeZinc kunye neHot Dip Galvanizing

I-Zinc yintsimbi esebenzayo kakhulu, xa ifakwe kwintsimbieshushu-dip galvanizing, yenza uluhlu lwezinc-iron alloy layers phezu kwentsimbi. Ezi zingqimba zibonelela ngomqobo womzimba, ukukhusela intsimbi engaphantsi kwizinto ezitshabalalisayo ezifana nokufuma kunye ne-oxygen. Ukongezelela, i-zinc yokugqoka isebenza njenge-anode yombingelelo, oku kuthetha ukuba ukuba i-coating yonakaliswe, i-zinc i-coating iya kugqwala ngokukhetha intsimbi, ikhusele ngakumbi insimbi ekungcoleni.

Kwiimeko ezininzi, i-zinc yokugqoka kwintsimbi ye-galvanized inikezela ukukhuselwa kwexesha elide lokubola nakwiindawo ezinzima. Nangona kunjalo, kwezinye iimeko, ukugquma kwegalvanized kungaphazamiseka, okukhokelela kwi-corrosion enokwenzeka yentsimbi engaphantsi. Enye imeko enjalo kukuvezwa kwindawo ene-acidic okanye i-alkaline, ekhawuleza ukubola kwe-zinc coating kunye nokunciphisa iimpawu zayo zokukhusela. Ukongeza, ukuvezwa ixesha elide kumaqondo obushushu aphezulu kunokubangela ukuba i-zinc coating ibe mandundu, nto leyo enokubangela ukubola kwe-substrate yentsimbi.

Kubalulekile ukuba uqaphele ukuba ngelixa i-zinc igubungeleintsimbi ekhandiweyoiyasebenza kakhulu ekukhuseleni intsimbi kwi-corrosion, ayikhuselekanga kumonakalo. Ukulimala komatshini, njengama-scratches okanye i-gouges, kunokuphazamisa ingqibelelo yengubo ye-zinc kwaye ibeke insimbi engaphantsi kwengozi yokubola. Ngoko ke, ukuphathwa ngokufanelekileyo kunye nokugcinwa kweemveliso zetsimbi ezinqatyisiweyo kubalulekile ukuqinisekisa ukuxhathisa ukubola kwexesha elide.

Ukuququmbela,idiphu eshushu igalela, ekwabizwa ngokuba yi-zinc pot, yindlela esebenzayo yokukhusela intsimbi kwi-corrosion.Ukugalelayenza umaleko okhuselekileyo okhuselayo kwindawo yentsimbi, ebonelela ngokumelana nokugqwala kwexesha elide kwiindawo ezininzi. Ngelixa iingubo ezinobumba zingonakaliswa phantsi kweemeko ezithile, ukugcinwa okufanelekileyo kunye nokuphathwa kweemveliso zensimbi kunceda ukuqinisekisa ukuxhathisa kwazo okuqhubekayo. Ngokubanzi, isinyithi esinama-galvanized sihlala sinokwethenjelwa kwaye sihlala sikhethiweyo kwizicelo ezahlukeneyo ngenxa yeempawu zokukhusela ze-zinc coating.
