Cov yob loj ntawm galvanized hlau yog nruj heev tua nyob rau hauv oxygen thiab sparks radiate, thaum lub sodium block thiab magnesium bar yog extinguished nyob rau hauv oxygen thiab tsis muaj sparks radiate.Qhov no tshwm sim yog txiav txim los ntawm cov muaj pes tsawg leeg ntawm loj yob ntawm galvanized hlau.Cov yob loj ntawm galvanized hlau siv nyob rau hauv qhov kev sim yog npua hlau los yog hlau hlau, ob qho tib si ntawm cov hlau thiab cov pa roj carbon monoxide (cov khoom nyuaj uas muaj cov ntsiab lus hlau thiab carbon).Thaum cov pa roj carbon nyob rau hauv galvanized xaim raug tua, carbon dioxide yuav raug tsim, thiab cov khoom yuav raug hloov mus rau hauv cov roj, thiab lub ntim yuav poob sai.
Galvanized hlau tuaj yeem pom zoo li hlau qhwv hauv cov pa roj carbon monoxide, thaum tua, qhov saum npoo yog piv rau cov pa roj carbon monoxide tuaj yeem tiv tauj nrog oxygen, tsim cov pa roj carbon dioxide, yuav qhwv nws hauv cov hlau (qhov no yog lub xeev molten) hluav taws xob nyob rau hauv. Qhov ntau carbon muaj. yog nyob rau hauvgalvanized hlau, qhov ntau yuav ua rau spark.Cov hlau-encased carbon zoo li dynamite nyob rau hauv ib lub hnab dynamite, tshuab cov hlau mus ib ntus.
Sodium thiab magnesium muaj tsawg combustible impurities, thiab thaum extinguished, lawv tsuas ci.Galvanizing belongs rau cov txheej txheem electrochemical uas yog dav siv nyob rau saum npoo ntawm hlau.Yog li nws yog, ua ntej ntawm tag nrho cov, vim zinc txheej (tshwj xeeb tshaj yog tom qab ntxiv kev ua, xws li kev kho chromate thiab phosphating) tsis kam rau huab cua thiab dej yog ruaj khov, thiab cov txheej txheem galvanized nws tus kheej yog pheej yig dua thiab yooj yim.
Zinc txheej ntawm cov hlau thiab ferrous hlau ua lub luag haujlwm anodic, feem ntau yog siv rau cov khoom uas raug cua lossis dej ua haujlwm, tab sis zinc txheej tsuas yog thaum dej kub qis dua 60 ℃, cov khoom siv anode.Thaum qhov kub siab dua, qhov muaj peev xwm hloov pauv thiab zinc rau hlau ua cov cathode.Yog li ntawd, rau qhov chaw raug dej kub (xws li chav boilers), cov pob txha zinc yuav tsum yog kwv yees li 70 microns tuab thiab tsis muaj dab tsi.Rau qhov chaw uas muaj qhov kub thiab txias los yog huab cua ua haujlwm, zinc txheej tsis muaj pinholes tsis tsim nyog.
Lub electrolytic deposition ntawm loj yob galvanized hlau zinc-chin txheej txheej yog yeej muaj ob hom electrolyte nram qab no: zinc yog tsuas yog nyob rau hauv daim ntawv ntawm zinc cation hydration nyob rau hauv cov tshuaj;Zinc feem ntau yog tam sim no nyob rau hauv kev daws raws li complex anion.Acid electrolyte belongs rau ib chav kawm, complex cyanide thiab zincate electrolyte, thiab nickel sulfate electrolyte yog chav kawm thib ob.Cyanide electrolyte thiab acid electrolyte yog qhov tseem ceeb heev.
