Thaum lub workpiece xav tau lub sijhawm ntev ntawm kev khaws cia thiab kev thauj mus los, nws yooj yim los tsim corrosion, thiab cov khoom siv corrosion feem ntau yog xeb dawb.Lub workpiece yuav tsum tau passivated, thiab txoj kev passivating feem ntau yog chromium-dawb passivation.
Yog li dab tsi yog qhov zoo ntawm stainless hlau ib puag ncig tiv thaiv (tsis muaj chromium) passivation tov tshaj xeb tiv thaiv roj?Anti-xeb roj yog siv cov roj zaj duab xis los kaw qhov pores ntawm cov hlau nto kom cais kev sib cuag nrog cov pa oxygen thiab tiv thaiv xeb, qhov tseeb, tsis muaj tshuaj tiv thaiv.Cov roj zaj duab xis yog ib qho yooj yim kom tshem tawm thiab rhuav tshem nrog kev nce qib ntawm kev tsim khoom.
Cov chromium-dawb passivation yog siv cov oxidizing tshuaj nyob rau hauv cov tshuaj passivation los tsim REDOX cov tshuaj tiv thaiv nrog cov hlau, thiab cov nyhuv yog tsim kom muaj ib tug heev nyias, ntom, zoo npog kev ua tau zoo, thiab nrees adsorbed ntawm cov hlau nto ntawm passivation zaj duab xis. .
Cov txheej txheem no yog tshuaj tiv thaiv.
Yog li tib lub sijhawm, cia peb nkag siab qhov zoo ntawmstainless hlau ib puag ncig tiv thaiv(chromium-dawb) passivation tov?
1. Muab piv nrog cov txheej txheem kev sib khi ntawm lub cev, chromium-dawb passivation kev kho mob muaj cov yam ntxwv ntawm tsis ua kom cov thickness ntawm lub workpiece thiab hloov xim, txhim kho qhov precision thiab ntxiv tus nqi ntawm cov khoom, ua rau kev ua haujlwm yooj yim dua.
2. Chromium-free passivation txhawb kev tsim cov pa oxygen molecular qauv passivation zaj duab xis rau ntawm cov hlau nto, cov zaj duab xis txheej yog ntom, ruaj khov kev ua tau zoo, thiab nyob rau hauv cov huab cua, yog li ntawd, piv nrog cov tsoos txoj kev ntawm txheej los tiv thaiv xeb roj, passivation. zaj duab xis tsim los ntawm chromium-dawb passivation yog ruaj khov thiab ntau corrosion resistant.
EST Chemical Grouptau ua raws li "lub siab los muab cov neeg siv khoom nrog cov khoom sib tw thiab cov kev pabcuam rau cov txiaj ntsig ntawm tib neeg lub neej" lub hom phiaj kev ntseeg, kev tsim kho tshiab tas li, rau cov neeg siv khoom los daws cov teeb meem hauv kev tiv thaiv kev tiv thaiv xeb, muab cov khoom lag luam zoo siab, thiab raws li cov neeg siv khoom xav tau los muab cov kev daws teeb meem tag nrho kom tau raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom.Peb mob siab rau muab cov kev pabcuam zoo thiab cov khoom zoo rau txhua tus neeg siv khoom, thiab tos ntsoov yuav ua haujlwm nrog koj kom yeej!
