Ntau cov txheej txheem kho deg ua ntej Electroplating Automotive xim ntawm hluav taws xob cua sov raj

Txhawm rau kom tau txais cov txheej txheem zoo, kev ua haujlwm ua ntej kev kho mob uas yuav tsum tau ua nyob rau saum npoo ntawm cov khoom coated ua ntej lub tsheb pleev xim yog hu ua kev kho deg ua ntej lub tsheb pleev xim. Kev kho deg ua ntej lub tsheb tha xim yog lub hauv paus ntawm cov txheej txheem tha xim, uas muaj kev cuam tshuam loj rau qhov zoo ntawm tag nrho cov txheej txheem, feem ntau suav nrog kev ntxuav saum npoo (kwv yees, tshem tawm xeb, tiv thaiv plua plav, thiab lwm yam) thiab kev kho phosphating.

Muaj ntau ntau txoj hauv kev rau kev ntxuav saum npoo:

1. Ntxuav nrog cov tshuaj kub alkaline thiab txhuam nrog cov kuab tshuaj organic kom tshem tawm cov roj stains; Sib tsoo saum npoo ntawm fiberglass nrog 320-400 grit sandpaper ua ntej, thiab tom qab ntawd ntxuav nrog cov kuab tshuaj organic kom tshem tawm tus neeg sawv cev tso tawm; Cov xeb daj nyob rau saum npoo ntawm lub cev lub tsheb yuav tsum tau muab ntxuav nrog cov tshuaj ntxuav tais diav uas npaj nrog phosphoric acid kom ntseeg tau tias muaj kev tiv thaiv corrosion zoo ntawm cov txheej thiab adhesion zoo ntawm cov txheej thiab cov txheej txheej.

2. Ua ntau yam tshuaj kho mob rau ntawm qhov chaw ntxuav ntawm coated hlau qhov chaw los txhim kho cov adhesion thiab corrosion kuj ntawm cov xim zaj duab xis. Kev kho tshuaj tshwj xeeb yog siv rau cov phaj steel los txhim kho qhov adhesion ntawm cov xim zaj duab xis thiab cov substrate.

3. Siv cov txheej txheem siv tshuab los tshem tawm cov kev ua haujlwm tsis zoo ntawm cov txheej txheem thiab tsim kom muaj qhov xav tau roughness rau cov zaj duab xis txheej. Cov txheej txheem kev kho phosphating muaj xws li kev siv tshuaj txau thiab kev sib xyaw ua ke. Kev siv nyias zaj duab xis zinc ntsev sai phosphating kev kho mob, nrog phosphating zaj duab xis loj ntawm 1-3g / m2 thiab ib zaj duab xis thickness ntawm 1-2 μ m. Crystalline particle loj 1-10 μ m. Phosphating tuaj yeem ua tau ntawm qhov kub qis ntawm 25-35 degree lossis nruab nrab kub ntawm 50-70 degree .
