Lub ntsej muag huv ntawm cov tshuab hlau steel hlau raj ua si yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntau yam khoom noj thiab cov tshuaj. Ib qho zoo nto tiav tiav yuav pab txo cov microbial kev loj hlob thiab ua kom pom kev corrosion tsis kam. Txhawm rau txhim kho qhov chaw zoo ntawm 316Stainless hlauKev tu cev cov kav dej, txhim kho cov qauv morphology thiab cov qauv, thiab txo tus naj npawb ntawm cov kev cuam tshuam, cov txheej txheem kho deg muaj xws li cov hauv qab no:
1. Acid pickling, polishing, thiabPassivation: Cov kav dej uas acid pickling, polishing, thiab passivation, uas tsis ua kom muaj kev sib tw saum npoo av rau saum npoo av, txo cov zog. Nws tsis yog, txawm li cas los xij, txo tus naj npawb ntawm cov interfaces. Ib daim ntawv hla kev hla kev ntawm cov roj chromium oxide cov ntaub ntawv ntawm cov hlau stainless sab, tiv thaiv nws los ntawm kev xeb.
2. Neeg kho tshuab sib tsoo thiab polishing: Kev sib tsoo ceev yog ua haujlwm txhawm rau txhim kho qhov chaw roughness, txhim kho cov qauv npoo deg. Txawm li cas los xij, nws tsis txhim kho cov qauv morphological, lub zog qib, lossis txo tus lej sib cuam tshuam.
3. Electrolytic Polishing: Electrolytic polishing tseem ceeb txhim kho cov nplaim hluavtaws thiab qauv, txo cov chaw tiag tiag rau qhov chaw loj. Cov nplaim ntaub ntawv kaw chromium oxide zaj duab xis, nrog lub zog theem nce qib ib txwm muaj ntawm cov alloy. Ib txhij, tus naj npawb ntawm interfaces yog tsawg.
