Feem ntau siv stainless hlau nto kho tshuab muaj cov kev kho mob hauv qab no: ① kev kho hniav ntxuav hniav dawb; ② nto daim iav ci kev kho mob; ③ kho qhov chaw xim.
Kev kho kom zoo nkauj saum npoo: Thaum lub sij hawm ua cov hlau tsis muaj steel, cov tawv nqaij dub oxide yog tsim los ntawm dov, khi, vuam lossis cov khoom siv hluav taws xob cua sov. Qhov nyuaj grey-dub oxide nplai no yog tsim los ntawm ob lub EO4 Cheebtsam, NiCr2O4 thiab NiF. Yav dhau los, hydrofluoric acid thiab nitric acid feem ntau yog siv rau kev tshem tawm corrosion. Txawm li cas los xij, txoj kev no muaj tus nqi siab, ua rau ib puag ncig, muaj kev phom sij rau tib neeg lub cev, thiab corrosive heev, thiab maj mam tshem tawm. Tam sim no, muaj ob txoj hauv kev tseem ceeb ntawm kev kho tawv nqaij oxide:
(1) Xuab zeb blasting (pellet) txoj kev: feem ntau yog siv txoj kev txau micro iav hlaws kom tshem tawm cov xim dub oxide ntawm qhov chaw.
(2) Cov txheej txheem tshuaj: Siv cov tshuaj tsis muaj kuab paug pov tseg thiab cov tshuaj ntxuav tsis muaj tshuaj lom nrog cov tshuaj inorganic additives ntawm chav tsev kub rau dipping. Yog li kom ua tiav lub hom phiaj ntawm whitening lub ntuj xim ntawm stainless hlau. Tom qab ua tiav, nws yeej zoo li cov xim npub. Txoj kev no yog tsim nyog rau cov khoom loj, complex.
