Dab tsi yog qhov cuam tshuam ntawm hom ntawm cov nyom ntawm tus neeg sawv cev ntawm plating ceev?

Nyob rau hauv cov txheej txheem ntawm tshuaj nickel plating, hom ntawm tus neeg sawv cev sib txawv, cov qauv tshuaj sib txawv ntawm cov tshuaj tiv thaiv kab mob sib txawv thiab cov tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv kab mob hauv lub Plating Cov Lus Qhia .} Hauv qab no yog kev tsom xam cov teebmeem tshwj xeeb ntawm cov neeg tus neeg sawv cev uas muaj kev sib tw ntawm lub plating ceev:
Kuv . kev faib tawm ntawm cov neeg sawv cev thiab lawv cov cawv ntawm lub plating ceev
Raws li lub zog ntawm kev sib koom tes muaj peev xwm ntawm cov neeg sawv cev uas muaj hnub nyoog thiab cov neeg sawv cev ua haujlwm tsis muaj zog, thiab lawv cov kev cuam tshuam rau qhov kev nrawm nrawm yog qhov txawv tshaj plaws:
1.} muaj zog ua cov neeg sawv cev (xws li sodium angelylenedismacinetetrai acid (Edrta), citric acid thiab nws cov ntsev)
Kev Muaj Peev Xwm Ua Haujlwm: Tsim ruaj ntseg nrog Ni-Edrta, ni-citric acid complex {.
Cawv rau ntawm plating ceev:
Thawj zaug plating ceev yog tsawg: muaj zog complexation ua rau muaj kev ywj pheej ntawm cov tshuaj tiv thaiv dawb, thiab kev tso tawm cov tshuaj tiv thaiv ntawm Nickel ions .
Cov Plating Cov Plab Txiaj Ntsig Ruaj Khwv: Cov neeg sawv cev muaj zog ua rau muaj kev sib txuam ua ntej, thiab haum rau kev sib tw ua ntej lossis qib siab.
Tus nqi pH muaj qhov cuam tshuam tseem ceeb: nws yog qhov tsim nyog yuav tsum nce rau qhov kev sib cais ntawm cov neeg sawv cev sib cais, nws yuav ua rau txoj kev sib cais dhau los, nws yuav ua rau txoj kev sib cav sib ceg
2. Weak complexing agents (such as organic acids such as lactic acid, propionic acid, and malic acid)
Lub peev xwm ua kom sib haum xeeb: nws tsim cov dej tsis muaj zog nrog cov nickel ions, thiab muaj ntau dua ntawm Ni²⁺ pub dawb yog khaws cia rau hauv cov plating tov .
Cuam tshuam rau kev nrawm nrawm:
Thawj zaug plating ceev yog sai sai: lub concentration ntawm Dawb Ni²⁺ yog qhov yooj yim, hypophosphaphite), thiab tus nqi rho tawm yog qhov siab .
Qhov kev ruaj ntseg ntawm cov kev daws teeb meem yog tsawg: qhov tsis muaj zog ua rau tus neeg sawv cev rau tus kheej, uas yuav ua rau cov kev txiav txim siab txo tus kheej, tshwj xeeb tshaj yog thaum muaj kub siab lossis siab}
Tsawg Phuam: Ib qho kev ntseeg pub dawb tuaj yeem tswj hwm ntawm tus nqi hauv qab (xws li high} 2 ~ 6. 6. 6. 6. 6)
2. sib piv ntawm Plating Ceev ntawm Cov Neeg Tus Neeg Sawv Cev
Cov neeg saib xyuas tus neeg saib xyuas muaj zog tshaj plaws hauv kev ua kom muaj zog dawb niunes concentration thawj plating thawj zaug cov xwm txheej ruaj khov ntev ntev
Edta (muaj zog complexing tus neeg sawv cev) muaj zog qis qeeb qeeb precision qhov chaw, ntev---voj voog plating daws
Citric acid (muaj zog complex
Lactic acid (tsis muaj zog comllexing tus neeg sawv cev) tsis muaj zog ceev ceev qis qis ceev no nickel plating, me me batch
Propionic acid (tsis muaj zog comllex
{{03.} synergistic cov nyhuv ntawm cov hom neeg sawv cev nyuaj thiab lwm yam
Sib txuam nrog txo tus neeg sawv cev:
Cov neeg ua haujlwm tsis muaj zog ua tau yuav tsum tau sib piv nrog cov kev ua kom muaj kev cuam tshuam zoo, tab sis nws yog qhov yooj yim los tswj cov neeg sawv cev siab (phosphates yog tsim los ntawm cov kev tsis zoo siab) .
Cov neeg sawv cev muaj zog ua tau cov tshuaj tiv thaiv qis dua nrog cov qis dua ntawm cov sodium
Ntxim Kub Kub:
Lub plating ceev ntawm cov neeg sawv cev tsis muaj zog ua tau zoo dua ntawm cov kev daws teeb meem siab tshaj plaws vim tias qhov txo qis (complex dissociation).
Tus neeg sawv cev muaj zog muaj zog tseem tuaj yeem tswj tau ruaj khov ntawm qhov kub thiab txias, thiab lub plating ceev yog qeeb dua li qhov kub .
Kev tswj hwm tus nqi PHO:
Cov neeg sawv cev tsis muaj zog ua haujlwm xav tau nruj me ntsis kev hloov pauv ntawm cov tsiaj ua kom tsis txhob muaj cov tsiaj sib cav sib ceg
Iv {.} cov ntsiab cai rau xaiv cov nyom hom
Ua ntej qhov kev xav tau ntawm cov kev daws teeb meem:
Yog tias cov khoom siv tau txuas ntxiv mus ntev lossis cov khoom siv hluav taws xob (xaiv cov khoom siv hluav taws xob (xaiv cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob (xws li edta + citric acid compound) .
Ua ntej tshaj tawm cov txheej txheem plaub ntug kom zoo:
Yog tias yuav tsum tau txais kev tshem tawm sai (xws li kev kho txheej txheej, xws li cov tawv nqaij tawv (xws li theras factiless (xws li inhosticial compompraption .
Xav txog tus nqi thiab kev tiv thaiv ib puag ncig:
Organic acids (lactic acid, citric acid) yog tus nqi qis thiab yooj yim biodegradable, haum rau ib puag ncig cov txheej txheem phooj ywg zoo; Cov neeg sawv cev muaj zog ua xws li Edta yog tus nqi siab, tab sis cov kev daws teeb meem muaj lub neej ntev dua.
Lub ntsiab
Cov neeg sawv cev ruaj khov sib zog ua kom ruaj khov rau cov neeg siv hluav taws kub kom txo qis dawb huv si, ua rau cov kev sib tw sib luag, tsim nyog rau cov kev xav tau zoo {}}
Cov neeg sawv cev tsis muaj zog muaj cov siab tawv plating uas muaj kev sib txig sib luag ntawm cov kab mob uas muaj kev sib luag thiab cov sab nrauv, thiab haum rau lub sijhawm luv luv plating .
Hauv kev siv cov tswv yim, cov neeg sawv cev sib xyaw ua ke (xws li cov neeg sawv cev sib xyaw ua ke -
