Kev sib piv ntawm cov hlau kub plating thiab electro galvanizing

Covkub plating hlautuaj yeem tsim cov txheej tuab, thiab muaj ob qho tib si ntshiab zinc txheej thiab hlau-zinc alloy txheej, yog li cov corrosion kuj zoo.Lub zog ntau lawm ntawm kub dip galvanizing yog tshwj xeeb tshaj yog siab, thiab lub sij hawm nyob twj ywm ntawm qhov chaw nyob rau hauv lub kub dip galvanizing tank feem ntau tsis tshaj lmin.Piv nrog electrogalvanizing, kub-dip galvanizing tau qis dua cov nqi tsim khoom thiab tsis cuam tshuam rau ib puag ncig dua li electroplating.Thaum plating daim hlau, siv, xov hlau, raj thiab lwm yam profiles, qhov degree ntawm automation yog siab.
"Wet" kub dip galvanizing tseem hu ua "molten solvent method" kub dip galvanizing.Tom qab steel workpiece degreased, pickled thiab ntxuav, nws yog ib qhov tsim nyog los hla lub "molten hnyav" (tseem hu ua lub co-solvent) nyob rau hauv ib tug tshwj xeeb tank teem saum toj no lub molten zinc nto, thiab ces nkag mus rau hauv cov zinc tov kom tshem tawm cov hlau. zinc plating.Cov kuab tshuaj molten feem ntau yog sib xyaw ntawm ammonium chloride thiab zinc chloride, tab sis lwm cov tshuaj chlorine kuj tau ntxiv.

"Dry" kub dip galvanizing kuj tseem hu ua "kev ziab kom qhuav" kub dip galvanizing.Hlau thiab steel workpieces los ntawm degreasing, pickling, tu, dipping pab hnyav thiab tom qab ziab, ces immersed nyob rau hauv molten zinc tov rau galvanize.Lub co-solvent feem ntau yog hydrochloric acid, ammonium chloride, los yog sib tov ntawm ammonium chloride thiab zinc chloride.
Scope ntawm kev siv: Vim hais tias cov txheej txheej yog thicker, kub-dip galvanizing muaj kev tiv thaiv zoo tshaj li hluav taws xob galvanizing, yog li nws yog ib qho tseem ceeb txij nkawm txheej rau steel qhov chaw nyob rau hauv nruj ua hauj lwm ib puag ncig.Cov khoom kub-dip galvanized yog siv dav hauv cov khoom siv tshuaj, kev ua roj av, kev tshawb nrhiav Marine, hlau qauv, hluav taws xob tsheb thauj mus los, shipbuilding thiab lwm yam haujlwm, hauv kev ua liaj ua teb xws li kev siv tshuaj tua kab, cua sov thiab kev tsim kho xws li dej thiab roj thauj, xaim bushings. , scaffolding, Choj, txoj kev loj guardrail, thiab lwm yam., cov xyoo no tau xaiv ntau yam.
