Passivation yog txheej txheem tom qab tsim khoom uas tau ua tom qab sib tsoo, vuam, txiav thiab lwm yam kev ua haujlwm machining uas tswj cov hlau tsis huv. Nyob rau hauv cov xwm txheej zoo tagnrho, stainless hlau naturally resists corrosion, uas yuav qhia tias passivating yuav tsis tsim nyog.
passivation ua dab tsi rau stainless hlau?
Passivation yog kev kho tshuaj rau cov hlau tsis muaj steel thiab lwm yam hlau uas txhim kho lub peev xwm ntawm cov chaw kho kom tiv thaiv corrosion. Muaj ntau yam txiaj ntsig ntawm cov khoom siv passivated thiab cov tshuab: Passivation tshem tawm cov kab mob ntawm qhov chaw. Passivation nce corrosion kuj.
Puas passivation tsim nyog?
Passivation yog qhov tsim nyog txhawm rau tshem tawm cov kab mob sib kis no thiab xa rov qab mus rau nws qhov qub corrosion specifications. Txawm hais tias passivation tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm qee yam stainless hlau alloys, nws tsis tshem tawm qhov tsis zoo xws li micro tawg, burrs, cua sov tint thiab oxide nplai.
Puas yog 304 stainless hlau yuav tsum tau passivated?
Passivation ntawm 304 Stainless Hlauthiab 316 Stainless Hlau Txhim Kho Kev Tiv Thaiv Corrosion. Passivation ntawm 304 stainless hlau yog ntau vim tias qib alloy no tsis muaj tib theem ntawm pitting corrosion kuj zoo li 316 stainless hlau.
Puas passivation cuam tshuam rau saum npoo?
7 Qhov saum npoo yuav tsum yog mechanicallypolished los yog lapped ua ntej passivation los muab qhov yuav tsum tau nto smoothness. Cov txheej txheem kua qaub / chelant yuav tsis cuam tshuam rau qhov chaw tiav. Vim tias qhov xwm txheej ntawm cov tshuaj siv, cov organic acid / chelant kev kho mob ua rau muaj kev nyab xeeb thiab kev txhawj xeeb ib puag ncig.
