Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam hlau, cov khoom siv stainless hlau tau pom cov ntawv siv dav hauv lub neej txhua hnub, kev tsim khoom lag luam, thiab kev ua tub rog.Thaum lub sij hawm ua, fabrication, thiab siv cov hlau tsis muaj steel, nws nto yuav pom cov xim tsis sib xws los yog cov kab xeb vim qhov kub-kub oxidation, nruab nrab corrosion, thiab lwm yam. Rau qhov zoo nkauj los yog daws cov teeb meem no,stainless hlau picklingthiabpassivation kev daws teeb meemfeem ntau yog ua hauj lwm rau tshuaj ntxuav thiab kev kho mob passivation.Cov txheej txheem no tsim ua tiav thiab cov yeeb yaj kiab tsis zoo rau ntawm qhov chaw, txhim kho cov khoom zoo nkauj thiab kev tiv thaiv corrosion, thiab txuas ntxiv lub neej ntawm stainless hlau.
Ua ntej siv cov stainless hlau pickling thiab passivation tov ntawm welded qhov chaw, stainless hlau nto yuav tsum tau undergo degreasing, tshem tawm cov av, thiab polishing.Ces, ncuav lubpassivation dawsrau hauv lub thawv yas thiab siv raws li cov khoom siv ntawm cov hlau tsis muaj steel thiab qhov hnyav ntawm oxidation.Muab cov khoom ua haujlwm tso rau hauv qhov kev daws teeb meem, feem ntau ntawm chav tsev kub, thiab raus rau 5-20 feeb lossis ntev dua (lub sijhawm tshwj xeeb thiab qhov kub thiab txias yuav tsum tau txiav txim los ntawm tus neeg siv raws li lawv cov kev xav tau tshwj xeeb).Tshem tawm cov khoom ua haujlwm tom qab tshem tawm tag nrho cov impurities saum npoo, thaum lub npoo zoo nkaus li nyiaj-dawb.Tom qab ntawv thiabpassivation, yaug cov workpieces kom huv si nrog dej huv thiab qhuav lawv.
