1.Vim li cas neutralization/rinsing tsim nyog?
Tshem Tawm Cov Acid Residual: Tom qab pickling, ib tug loj npaum li cas ntawm cov residual acid (feem ntau yog hydrochloric acid los yog sulfuric acid) adheres rau saum npoo thiab crevices ntawm lub sawb. Yog tias tsis raug tshem tawm kom zoo, cov kua qaub no yuav:
Txuas ntxiv mus rau corrode lub strip: Corrosion yuav txuas ntxiv txawm tias thaum lub sij hawm tom ntej coiling thiab cia, ua rau xeb ntawm lub strip nto thiab cuam tshuam rau cov khoom zoo.
Kev puas tsuaj tom qab cov khoom siv: Cov kua qaub seem yuav corrode cov cuab yeej kim xws li dov mills thiab annealing furnaces.
Kev cuam tshuam rau kev ua haujlwm ntawm cov roj dov / roj lubricating: Acid yuav ua rau muaj kev cuam tshuam tsis zoo nrog cov roj dov, cuam tshuam rau kev ua haujlwm dov thiab kev huv ntawm qhov chaw.
Npaj kom huv si rau cov txheej txheem tom ntej:
Rolling: Ib qho huv huv, tsis muaj kab mob -dawb hlau saum npoo yuav tsum tau ua kom muaj txheej txheem dov ruaj khov thiab tau txais daim ntawv zoo thiab qhov zoo.
Zinc / Tin Plating, thiab lwm yam .: Cov txheej txheem txheej tom ntej muaj qhov xav tau siab heev rau kev huv ntawm substrate; cov kua qaub los yog ntsev seem yuav ua rau tsis zoo txheej adhesion thiab tsis xws luag.
Tsim cov txheej tiv thaiv ib ntus (passivation):
Nyob rau hauv cov kab niaj hnub no, cov dej yaug zaum kawg feem ntau yog xeb-cov tshuaj tiv thaiv uas muaj cov kab mob kis tau (xws li phosphates, silicates, lossis qee cov organic reagents).
Qhov no tsis tshua muaj kev tiv thaiv zaj duab xis tiv thaiv cov sawb los ntawm xeb dua nyob rau hauv ib lub sij hawm luv luv (lub sij hawm luv luv los ntawm cov kab pickling tawm mus rau qhov txias dov zeb nkag), muab cov khoom tsim nyog rau cov txheej txheem txias dov.
2.Dab tsi yog qhov ua ntej-kev ntxuav/suav?
Lub sawb thawj zaug dhau los ntawm ib khub ntawm cov hlua khi kom nyem tawm feem ntau ntawm cov kua qaub uas nws nqa.
3.Dab tsi yog qhov multi-theem countercurrent rinsing txheej txheem?
Lub steel sawb ua ntej nkag mus rau qhov kawg (huv) lub tank rinsing, txav mus tom ntej hauv theem.
Cov dej ntws ntawm cov dej ntxuav yog qhov sib txawv ntawm cov hlau sawb: cov dej tshiab deionized los yog cov dej demineralized ntxiv los ntawm cov dej yaug kawg thiab tom qab ntawd ntws mus rau hauv lub tank dhau los, thiab lwm yam.
Qhov "counter{0}}tam sim no" tsim siv cov khoom siv dej zoo tshaj plaws, yaug cov hlua hlau nrog cov dej huv tshaj plaws ua ntej nws nkag mus rau cov txheej txheem tom ntej, kom ntseeg tau tias kev tu kom zoo thiab siv dej tsawg.
4.Dab tsi yog cov txheej txheem rinsing thiab passivation?
Nyob rau hauv qhov kawg rinsing tank, ib tug npaj xeb inhibitor yog ntxiv rau maj mam passivate nto ntawm lub sawb hlau.
5.Dab tsi yog txheej txheem ziab?
Tom qab yaug, lub sawb tam sim ntawd nkag mus rau hauv lub tshuab ziab khaub ncaws kom huv si kom tshem tawm cov av noo thiab xyuas kom meej tias nws qhuav tag ua ntej nkag mus rau hauv lub tshuab dov lossis coiling.
