Kev kos duab ntawm galvanized hlau nyob rau hauv qhov sib txawv kub ib puag ncig

Loj kaujgalvanized hlauyog tsim los ntawm kev kos duab hlau, hlau kos duab yog cov txheej txheem ua, tuaj yeem ua cov khoom kom tau raws li qhov xav tau thiab ua tau raws li tus qauv siv tshuab.Kev kos duab txias xaim yog nqa tawm ntawm qhov kub ntawm recrystallization, kub xov hlau yog nqa tawm ntawm crystallization kub, sov hlau daim duab yog kos ntawm siab dua chav tsev kub thiab qis dua crystallization kub.Kev kos duab txias yog ib txoj kev kos duab.Kev kos duab kub yog qhov cua sov ntawm cov hlau ua ntej nws nkag mus rau hauv qhov tuag.Nws yog tsuas yog siv rau kos cov hlau nrog siab melting point.

Kev ntsuas kub yog nqa tawm los ntawm cua sov lub rhaub mus rau qhov ntsuas kub, feem ntau yog siv rau kev kos duab ntawm galvanized steel hlau, nyuaj rau deform.Galvanized hlauyog ua tiav los ntawm cov txheej txheem kev kos duab, tsim cov qauv tshwj xeeb ntawm cov hlau hlau, thiab tom qab ntawd hauv lub tank electroplating los ntawm tam sim no unidirectional zinc plating rau saum npoo.Kev ua haujlwm nrawm nrawm heev, zinc txheej ntawm galvanized zinc yog qhov sib xws, lub thickness yog nyias, feem ntau nyob rau hauv 3 ~ 15 microns, lub ci ci yog siab heev, tab sis cov corrosion kuj tsis zoo, thiab nws pom zoo kom yuav. raws li qhov xav tau thaum siv.

Kev siv dav ntawm qhov lojgalvanized hlauCov khoom lag luam feem ntau yog vim nws cov tshuaj tiv thaiv xeb thiab tiv thaiv corrosion, vim zinc muaj kev tiv thaiv zoo ntawm cov khoom muag, yog li nws zoo heev txhim kho lub luag haujlwm thiab cov yam ntxwv ntawm cov khoom nws tus kheej, thiaj li txhawb kev siv cov khoom siv. khoom.Zinc txheej ntawm zinc hlau nrog tuab zinc txheej muaj zoo crystallinity, uniform thiab tsis muaj void, thiab zoo corrosion kuj.

Cov zinc txheej ua los ntawm electrogalvanizing yog ntshiab heev thiab corrosion yog qeeb hauv acid thiab alkali roj, kua thiab pos huab, uas tuaj yeem tiv thaiv cov hlau matrix zoo.Galvanized txheej kuj tuaj yeem kho los ntawm chromic acid passivation rau ntau yam xim, zoo nkauj thiab dav, nrog rau cov hniav zoo nkauj.Zinc txheej ntawm galvanized hlau muaj qhov zoo ductility thiab tuaj yeem ua rau txias txias, dov, khoov thiab lwm yam molding yam tsis ua rau cov zinc txheej.
