Passivation yog siv dav hlau txheej txheej txheem los tiv thaiv corrosion. Hauv stainless hlau, cov txheej txheem passivation siv nitric acid los yog citric acid kom tshem tawm cov hlau dawb ntawm qhov chaw. Kev kho tshuaj lom neeg ua rau muaj kev tiv thaiv oxide txheej uas tsis tshua muaj kev cuam tshuam nrog huab cua thiab ua rau corrosion.
Lub hom phiaj ntawm kev ua siab ntev yog dab tsi?
Passivation yog tshuaj kho rau cov hlau tsis muaj steel thiab lwm yam hlau uas txhim kho lub peev xwm ntawm qhov 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.
Passivated txheej yog dab tsi?
Passivation yog txheej txheem ntawm kev kho lossis txheej txheej hlau txhawm rau txo cov tshuaj reactivity ntawm nws nto. Hauv stainless hlau, passivation txhais tau tias tshem tawm cov hlau dawb los ntawm qhov chaw ntawm cov hlau siv cov kua qaub los tiv thaiv xeb.
Puas passivation ntawm stainless hlau 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 passivation tshem tawm xeb?
In general, passivationtsis tso cov stains uas twb muaj lawm los yog xeb. Qhov ntawd yuav tsum muaj lwm txoj hauv kev, xws li lub teeb abrasion, hlaws blasting, tumbling thiab qee zaum xuab zeb. Passivation kuj tsis tshem tawm cov nplais, cov oxide dub thiab hlawv cov cim los ntawm vuam.
