Electroplating yog txheej txheej txheej txheej txheej txheej txheej txheej txheej ntawm hlau, alloys lossis lwm yam ntaub ntawv yog coated nrog ib txheej zinc rau kev zoo nkauj thiab tiv thaiv xeb. Cov txheej txheem tseem ceeb yog kub-dip galvanizing.
Zinc yog yooj yim soluble hauv acid thiab alkali thiab yog li hu ua amphoteric hlau. Zinc tsis tshua hloov hauv huab cua qhuav. Nyob rau hauv cov huab cua ntub, qhov ntom ntom, yooj yim zinc carbonate zaj duab xis ua rau ntawm zinc nto. Nyob rau hauv cov huab cua uas muaj sulfur dioxide, hydrogen sulfide thiab marine atmospheres, zinc muaj tsis zoo corrosion kuj. Cov zinc txheej corrodes yooj yim, tshwj xeeb tshaj yog nyob rau hauv cov huab cua uas muaj kub, high humidity thiab organic acids. Cov txheej txheem electrode muaj peev xwm ntawm zinc yog -0.76 V. Rau steel substrates, zinc txheej yog anodic txheej. Nws yog tsuas yog siv los tiv thaiv corrosion ntawm steel. Lawv kev tiv thaiv kev ua tau zoo yog ze rau lub thickness ntawm txheej. Tom qab passivating, xim lossis txheej txheej zinc nrog cov ci ntsa iab, nws cov khoom tiv thaiv thiab cov hniav tuaj yeem txhim kho tau zoo.
Txias galvanizing tseem hu ua electro galvanizing. Cov yeeb nkab fittings yog degreased siv cov khoom siv electrolysis, pickled thiab ces muab tso rau hauv ib qho kev daws ntawm zinc ntsev. Qhov tsis zoo electrode ntawm cov khoom siv electrolysis yog txuas nrog. Muab ib lub phaj zinc rau sab nraud ntawm cov yeeb nkab fittings thiab txuas mus rau electrolyte. Thaum lub davhlau ya nyob twg zoo ntawm lub cuab yeej qhib, ib txheej ntawm zinc tso rau ntawm cov yeeb nkab fittings los ntawm kev siv cov kev taw qhia ntawm qhov tam sim no los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo davhlau ya nyob twg. Txias plated yeeb nkab fittings yog thawj machined thiab ces galvanized.
Lub zinc txheej yog thicker, finely crystallized, uniform thiab tsis pores, thiab muaj zoo corrosion kuj; zinc txheej tau los ntawm electroplating yog cov ntshiab thiab maj mam corrodes nyob rau hauv cov kua qaub, alkali thiab lwm yam pos huab, thiab muaj peev xwm tiv thaiv zoo matrix. Lub zinc txheej yog kho nrog chromic acid. Tom qab passivation, nws cov ntaub ntawv dawb, xim, tub rog ntsuab, thiab lwm yam, uas zoo nkauj thiab muaj qee yam khoom zoo nkauj. Txij li cov txheej txheej galvanized muaj cov ductility zoo, nws tuaj yeem ua kom txias txias, dov, khoov, thiab lwm yam yam tsis muaj kev puas tsuaj rau txheej. .
Kub-dip galvanizing yog tsim los ntawm cov laus kub-dip galvanizing txoj kev thiab muaj ib tug 170- xyoo keeb kwm txij li thaum Fabkis tau qhia kub-dip galvanizing rau kev lag luam nyob rau hauv 1836. Txawm li cas los xij, kev lag luam kub-dip galvanizing tau hloov zuj zus mus rau ntau yam. Peb caug xyoo dhau los nrog txoj kev loj hlob sai ntawm txias-dov strip steel.
Cov txheej txheem ntawm cov ntawv kub-dip galvanized feem ntau suav nrog: thawj daim ntawv npaj → pre-txheej kho → kub-dip galvanizing → tom qab txheej txheej kho → cov khoom kawg kuaj, thiab lwm yam. Feem ntau, cov txheej txheem kub-dip galvanizing muab faib ua ob pawg. : offline annealing thiab in-line annealing, raws li kev sib txawv ua ntej kev kho mob, uas yog txheej txheem ntub dej (kub-dip galvanizing txheej txheem rau ib lub phaj steel) thiab offline glow. Kab annealing (kub-dip galvanizing txheej txheem rau ib lub phaj steel). Galvanizing txheej txheem), kub-dip galvanizing Wheeling txheej txheem (nruam kub-dip galvanizing txheej txheem rau sawb hlau), in-line annealing Sendzimir txheej txheem (inert gas txheej txheem), hloov Sendzimir txheej txheem, American Steel Union txoj kev (zoo tib yam rau Nyiv txoj kev Kawasaki), Selas txoj kev thiab Sharon txoj kev.
Electroplating yog txheej txheej txheej txheej txheej txheej txheej txheej txheej ntawm hlau, alloys lossis lwm yam ntaub ntawv yog coated nrog ib txheej zinc rau kev zoo nkauj thiab tiv thaiv xeb. Cov txheej txheem tseem ceeb yog kub-dip galvanizing.
