Chromium-free passivation thiab sealing ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj txhim kho corrosion kuj tom qab galvanizing

Tom qab cov kev lag luam electro-galvanizing yog nyob rau hauv ntau lawm, cov workpieces yog nquag mus rau cov tshuaj tiv thaiv thaum muab tso rau hauv ib qho chaw huab cua ntub, ua rau cov pob dawb los yog dub. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua tiav passivation thiab sealing kev kho tam sim ntawd tom qab ua tiav. Taicang Jinfei Electroplating Co., Ltd. pom zoo siv galvanized thiab chromium-dawb passivation sealing tus neeg sawv cev, uas yog tsim tshwj xeeb rau qhov teeb meem no. Qhov no chromium-free passivation sealer muaj cov dej tsis zoo, tiv thaiv corrosion, kho thiab tiv thaiv ib puag ncig, thiab tau lees paub los ntawm cov neeg siv khoom. Qhov tseem ceeb tshaj plaws yog hloov cov passivation thiab sealing ntawm chromium ntsev, uas zoo heev txhim kho kev tiv thaiv ib puag ncig ntawm cov txheej txheem ntau lawm.

Ua kom ntseeg tau ib puag ncig tus phooj ywg ntau lawm, chromium-dawb passivation sealer yog dav launched

Yav dhau los, kev tiv thaiv kev kho mob tom qab galvanizing feem ntau yog acid passivation nrog hexavalent chromium, thiab cov nyhuv corrosion kuj zoo. Vim yog qhov phem ib puag ncig ntawm hexavalent chromium, daim ntawv thov hauv kuv lub teb chaws tau raug txwv nruj, yog li trivalent passivation tau dav siv, tab sis muaj ob qhov teeb meem nrog trivalent chromium passivation uas tsis tau daws: ib qho yog qhov tsis zoo ntawm passivation. Qhov zoo tshaj plaws, qhov thib ob yog tias tag nrho cov chromium hauv cov dej phwj tuaj tshaj tus qauv. Qhov tseeb, trivalent chromium passivation tseem yog chromium ntsev passivation, thiab nws cov kuab paug tsuas yog txo me ntsis, thiab nws tseem muaj tshuaj lom thiab muaj kev phom sij passivation.

Tom qab ntawd, chrome-dawb passivation sealer rau galvanizing tau ntse tsim thiab dav siv los ntawm ntau lub tuam txhab electroplating. Qhov laj thawj yog vim li cas nws thiaj li hais tias muaj kev tiv thaiv ib puag ncig zoo yog tias feem ntau ntawm nws cov khoom yog cov nroj tsuag rho tawm, uas muaj qhov zoo ntawm kev degradation yooj yim, tsis muaj tshuaj lom thiab kho tau yooj yim los nag; nws tuaj yeem siv rau lub sijhawm ntev yam tsis muaj qhov tshwm sim ntawm kev laus thiab tsub zuj zuj ntawm cov ions txaus ntshai; tsis muaj tshuaj lom, tsis muaj kuab paug pov tseg, tsis muaj kev phom sij rau tib neeg lub cev.
