Vim muaj cov txheej txheem kev tsim khoom sib txawv thiab siv cov hlau tsis muaj hlau, xws li cov duab kos duab, yeeb nkab dabtsi yog khoov, ib puag ncig, thiab lwm yam, qhov chaw ntawm stainless hlau phaj puas lawm, uas yuav ua rau xeb. Yog li dab tsi yog siv los tiv thaiv thiab ncua kev xeb ntawm cov kav hlau stainless? Dab tsi yog qhov zais cia ntawm kev tiv thaiv xeb thiab xeb tshem tawm rau cov hlau tsis muaj hlau?
Stainless hlau passivation kua yog tsim nyog rau me me thiab nruab nrab-qhov loj me stainless hlau workpieces nrog loj batch, loj tso zis thiab yooj yim soaking; xws li cov ntsia hlau, cov khoom siv sib txuas lus, stainless hlau precision castings, cov rooj tog me me, khoom noj khoom haus, cov khoom siv hluav taws xob, cov khoom siv kho vajtse, thiab lwm yam. Cov txheej txheem yog yooj yim siv, Soak ntawm chav tsev kub (ntau dua 15 degree), thiab txoj kev ua haujlwm. yog raws li nram no:
1. Degrease thiab degrease, ntxuav qhov chaw ntawm lub workpiece kom paub tseeb tias tsis muaj roj stain;
2. Ua kom, tsau lub workpiece nyob rau hauv passivation tov rau 2-5 feeb kom tshem tawm xeb, wax, vuam me ntsis thiab lwm yam impurities nyob rau saum npoo ntawm lub workpiece. Yaug lub workpiece nrog dej huv;
3. Passivation, soak lub workpiece nyob rau hauv cov tshuaj passivation rau ntau tshaj 30 feeb, lub sij hawm ntev, qhov ntau tiav cov passivation zaj duab xis; lub zog muaj peev xwm tiv thaiv xeb;
4. Tshaj dej ntshiab, yaug nrog dej huv rau ntau tshaj 3 feeb, thiab tom qab ntawd qhuav lossis txias kom qhuav
