I-hot dip galvanizing iyindlela esetshenziswa kabanzi yokuvikela insimbi ekugqwaleni. Icwilisa insimbi ebhavini le-zinc encibilikisiwe, yakha ungqimba oluvikelayo ebusweni bensimbi. Le nqubo ivame ukubizwa ngokuthiimbiza ye-zincngoba kuhilela ukucwilisa insimbi ebhodweni le-zinc encibilikisiwe. Insimbi ehlanganisiwe ephumayo yaziwa ngokuqina kwayo kanye nokumelana nokugqwala, okwenza kube ukukhetha okuthandwayo kwezicelo eziningi, kusukela ekwakheni kuya ekukhiqizweni kwezimoto.
Umbuzo ovamile ohlobene neukucwilisa okushisayoukuthi ingabe uqweqwe lwezinki luzoyigqwala yini insimbi egayiwe ngokuhamba kwesikhathi. Ukuze kuxazululwe le nkinga, kubalulekile ukuqonda izakhiwo ze-zinc nokuthi zixhumana kanjani ne-substrate yensimbi.
I-Zinc iyinsimbi esabela kakhulu, lapho isetshenziswa ensimbiniukucwilisa okushisayo, yakha uchungechunge lwezendlalelo ze-zinc-iron alloy ebusweni bensimbi. Lezi zendlalelo zihlinzeka ngesithiyo esibonakalayo, sivikela insimbi engaphansi ezintweni ezibolayo njengomswakama nomoya-mpilo. Ngaphezu kwalokho, isembozo se-zinc sisebenza njenge-anode yomhlatshelo, okusho ukuthi uma isembozo sonakele, isembozo se-zinc sizobola ngaphezu kwensimbi, sivikele insimbi ekugqwaleni.
Ezimweni eziningi, uqweqwe lwezinki ensimbini ehlanganisiwe luhlinzeka ngokuvikelwa kokugqwala kwesikhathi eside ngisho nasezindaweni ezinzima. Kodwa-ke, kwezinye izimo, uqweqwe lwezinki lungaba sengozini, okuholela ekugqwaleni okungenzeka kwensimbi engaphansi. Esinye isimo esinjalo ukuchayeka ezindaweni ezine-acidic noma ze-alkaline, okusheshisa ukugqwala koqweqwe lwezinki futhi kubeke engcupheni izakhiwo zalo zokuvikela. Ngaphezu kwalokho, ukuchayeka isikhathi eside emazingeni okushisa aphezulu kungabangela ukuthi uqweqwe lwezinki lonakale, okungase kuholele ekugqwaleni kwesisekelo sensimbi.
Kubalulekile ukuqaphela ukuthi ngenkathi i-zinc coating ivuliweinsimbi ehlanganisiweiyasebenza kakhulu ekuvikeleni insimbi ekugqwaleni, ayivikelekile ekulimaleni. Umonakalo wemishini, njengokuklwebheka noma ukugoba, ungalimaza ubuqotho bengubo ye-zinc futhi ubeke insimbi engaphansi engcupheni yokugqwala. Ngakho-ke, ukuphathwa kahle nokugcinwa kwemikhiqizo yensimbi ehlanganisiwe kubalulekile ukuqinisekisa ukumelana kwayo nokugqwala isikhathi eside.
Ekuphetheni,i-hot dip galvanizing, eyaziwa nangokuthi imbiza ye-zinc, iyindlela ephumelelayo yokuvikela insimbi ekugqwaleni.Ukuhlanganisa nge-galvanizingyakha ungqimba oluvikelayo oluhlala isikhathi eside phezu kwensimbi, oluhlinzeka ngokumelana nokugqwala isikhathi eside ezindaweni eziningi. Nakuba ukugqoka okuhlanganisiwe kungalimaza ngaphansi kwezimo ezithile, ukulungiswa kahle nokuphathwa kwemikhiqizo yensimbi ehlanganisiwe kusiza ukuqinisekisa ukumelana kwayo nokugqwala okuqhubekayo. Sekukonke, insimbi ehlanganisiwe ihlala iyisinqumo esithembekile nesihlala isikhathi eside sezinhlelo ezahlukahlukene ngenxa yezakhiwo zokuvikela zokugqoka okuhlanganisiwe okuhlanganisiwe okuhlanganisiwe.
