Khoom Qhia

Hom tshuaj pretreatment

Cov khoom siv kho mob ua ntej raws li cov duab ntawm lub workpiece thiab qhov sib txawv ntawm cov khoom ntim, cov txheej txheem tseem ceeb ntawm impregnation hom, qhov los ntawm cov tshuaj tsuag; hom impregnation yog tsim rau qhov loj, qhov chaw ruam, xws li cov khoom tsis loj heev; lub qhov los ntawm cov tshuaj tsuag yog tsim rau me me workpieces thiab zus tau tej cov kab ntau lawm.

Yam khoom siv:pre-treatment tanks (stainless steel los yog pob zeb tso tsheb hlau luam, tus naj npawb yog sib npaug rau cov txheej txheem ua ntej kho), cov kab tsuag.

Cov ntaub ntawv ntsig txog (chemicals):sulfuric acid, hydrochloric acid, dej qab zib tshauv (Na2CO3) acidic degreasing tus neeg sawv cev, passivation kua.

Lub hom phiaj:Tshem tawm cov roj, hmoov av, xeb ntawm qhov chaw ntawm lub workpiece, thiab tsim ib txheej ntawm corrosion kuj nyob rau saum npoo ntawm lub workpiece thiab yuav ua rau kom cov adhesion ntawm cov tshuaj tsuag txheej "phosphate txheej".

Cov txheej txheem tseem ceeb:degreasing, de-rusting, dej yaug, passivation. Lub workpiece tom qab pretreatment yuav tsis muaj roj, xeb, plua plav, thiab tus thawj silver-dawb glossy nto los tsim ib txheej ntawm uniform thiab ntxhib tsis yooj yim rau xeb grey phosphate zaj duab xis, tsis tsuas yog tiv thaiv xeb tab sis kuj ua rau kom cov adhesion ntawm cov tshuaj tsuag txheej. .

Kev daws dej khib nyiab:Siv ib puag ncig tus phooj ywg potion thiab cov khoom siv kho dej khib nyiab kom tau raws li tus qauv tso tawm tom qab kho.
