Cov txheej txheem txheej txheej muaj xws li hmoov txheej, Electro-plating, Anodizing, kub galvanizing, electro nickel plating, pleev xim rau, thiab lwm yam raws li cov neeg siv khoom xav tau.Kev ua haujlwm rau kev kho saum npoo yog nyob rau hauv kev rau siab tiv thaiv corrosion los yog tsuas yog txhim kho cov tsos.Tsis tas li ntawd, qee qhov kev kho mob no tseem muab cov khoom siv kho tshuab lossis hluav taws xob zoo dua qub uas ua rau muaj kev ua haujlwm tag nrho ntawm cov khoom siv.

Hmoov txheej los yog txau- Nrog rau hom kev kho mob no, cov khoom hlau yuav tsum tau preheated rau qhov kub thiab txias thiab tom qab ntawd muab cov khoom tso rau hauv lub txaj fluidized los yog txau cov hmoov rau ntawm qhov chaw.Nrog rau kev kho tom qab, nws nyob ntawm cov khoom tshwj xeeb ntawm cov hmoov.
Cov hmoov siv feem ntau yog cov khoom siv epoxy resin lossis Rilsan.

Electroplating- Cov txheej txheem no tsim cov txheej hlau nyias nyias ntawm lub substrate.Cov txheej txheem electroplating hla cov hluav taws xob zoo tam sim no los ntawm kev daws teeb meem uas muaj cov hlau ions yaj thiab cov hluav taws xob tsis zoo los ntawm cov hlau uas yuav tsum tau plated.Cov hlau feem ntau siv rau electroplating yog cadmium, chromium, tooj liab, kub, npib tsib xee, nyiaj, tin, thiab zinc.Yuav luag txhua lub hauv paus hlau uas ua hluav taws xob tuaj yeem electroplated los txhim kho nws cov kev ua tau zoo.

Tshuaj kho mob- Txoj kev no suav nrog cov txheej txheem uas tsim cov yeeb yaj kiab nyias ntawm sulfide thiab oxide los ntawm kev siv tshuaj lom neeg.Cov kev siv feem ntau yog rau xim hlau, tiv thaiv corrosion, thiab priming ntawm qhov chaw yuav tsum tau pleev xim rau.Dub oxide yog ib qho kev kho deg heev rau cov hlau thiab "passivation" yog siv los tshem tawm cov hlau dawb los ntawm qhov chaw ntawm cov hlau tsis muaj steel.

Anodic oxidation- Hom kev kho saum npoo no feem ntau yog siv rau lub teeb hlau, xws li txhuas thiab titanium.Cov oxide zaj duab xis no yog tsim los ntawm electrolysis, thiab txij li thaum lawv yog ntxeem tau, dyeing thiab colouring agents feem ntau teev rau ib tug txhim khu kev zoo nkauj tsos.Anodization yog kev kho mob ntau heev uas tiv thaiv corrosion ntawm txhuas qhov chaw.Yog tias hnav tsis kam kuj yog qhov xav tau, engineers tuaj yeem hais qhia txog cov qauv ntawm cov qauv no uas ua rau cov tuab tuab, tawv heev, ceramic txheej rau ntawm qhov chaw.

Kub Dipping- Cov txheej txheem no yuav tsum tau dipped rau hauv yaj tin, txhuas, zinc, txhuas, los yog solder los ua ib tug nto metallic zaj duab xis.Kub-dip galvanizing yog txheej txheem ntawm dipping hlau rau hauv lub nkoj uas muaj zinc molten.Siv rau corrosion kuj nyob rau hauv huab ib puag ncig, guardrails ntawm txoj kev yog feem ntau ua tiav nrog no nto kho.

Kev pleev xim- Kev pleev xim rau saum npoo yog feem ntau teev los ntawm cov kws tsim khoom los txhim kho ib feem ntawm qhov zoo li thiab tiv thaiv corrosion.Txau painting, electrostatic painting, dipping, txhuam, thiab hmoov coat painting txoj kev yog ib co ntawm cov feem ntau cov tswv yim siv los siv cov xim rau saum npoo ntawm cov khoom.Muaj ntau ntau hom kev pleev xim los tiv thaiv cov hlau hauv ntau qhov chaw ntawm lub cev.Kev lag luam automotive tau automated cov txheej txheem ntawm painting tsheb thiab tsheb thauj khoom, siv ntau txhiab tus neeg hlau caj npab thiab ua tau zoo ib yam nkaus.
