Qhov sib txawv tseem ceeb ntawm zinc thiab npib tsib xee plating yog zinc plating yuav tsum siv cov txheej nyias ntawm zinc ntawm cov khoom siv hluav taws xob thaum cov nickel plating cuam tshuam nrog kev siv cov txheej nyias ntawm nickel rau ntawm cov hlau. Ntxiv mus, nyob rau hauv zinc txheej, lub neej ntawm substrate nce tab sis, nyob rau hauv nickel plating lub lifespan ntawm txheej yog txwv.
Zinc thiab nickel plating yog cov txheej txheem tseem ceeb heev uas peb tuaj yeem siv los tiv thaiv cov khoom siv hluav taws xob. Txawm li cas los xij, zinc-nickel plating yog ib txoj kev sib txawv uas peb yuav tsum tsis txhob cuam tshuam nrog ob txoj kev no.
Zinc Plating yog dab tsi?
Zinc plating yog galvanization nyob rau hauv uas peb siv ib txheej nyias ntawm zinc rau saum npoo ntawm cov khoom siv hluav taws xob. Nws yog txoj kev tiv thaiv hlau thiab hlau txhawm rau tiv thaiv lawv ntawm xeb.
Daim duab 01: Ib qho chaw Galvanized
Tsis tas li ntawd, cov txheej txheem no feem ntau cuam tshuam nrog cov electrodeposition ntawm zinc ntawm lub substrate. Tsis tas li ntawd, feem ntau txoj kev ntawm no plating yog kub-dip galvanization nyob rau hauv uas peb poob lub substrate nyob rau hauv ib tug kub da dej ntawm molten zinc. Txawm li cas los xij, peb tuaj yeem siv electroplating ib yam nkaus. Cov txheej txheem electroplating suav nrog cov kauj ruam hauv qab no:
1. Kev npaj nto
2. Npaj cov tshuaj plating
3. Taw qhia txog hluav taws xob tam sim no
4. Kev kho mob tom qab
Txawm hais tias cov kauj ruam no zoo li yooj yim, zinc plating yog txheej txheem nyuaj heev uas yuav tsum tau siv cov cuab yeej ntse. Tsis tas li ntawd, zinc txheej ua raws li cov txheej txheem kev txi rau saum npoo ntawm substrate. Qhov ntawd txhais tau tias; zinc nkag mus rau oxidation, tab sis tsis yog lub substrate.
Pros and Cons of Zinc Plating
Pros
- Kev tsim cov hlau zinc yuav tsum muaj zog tsawg
- Yuav tsum muaj roj tsawg thaum tsim khoom
- Zinc yog recyclable
- Lub neej ntawm substrate nce
- Tsawg toxicity theem
Cons
- Condensation ntawm noo noo ntawm txheej yuav ua rau corrosion
- Tus nqi ntau lawm
- Tsis haum rau cov qauv loj lossis me dhau
Nco ntsoov yog dab tsi?
Nickel plating yog ib hom electroplating uas nyias txheej ntawm nickel yog siv rau saum npoo ntawm substrate. Ntawm no, peb tuaj yeem siv cov nickel txheej ua cov txheej zoo nkauj thiab. Ntxiv mus, npib tsib xee plating muab kev tiv thaiv corrosion thiab hnav tsis kam. Tsis tas li, peb tuaj yeem siv txoj kev no los tsim cov khoom hnav.
Daim duab 02: Electrolytic Nickel
Ua ntej plating pib, peb yuav tsum ua kom lub substrate nto tsis muaj av, corrosion, thiab tsis xws luag. Rau kev ntxuav ntawm lub substrate nto, peb tuaj yeem siv ntau txoj kev xws li kev kho cua sov, npog, pickling, thiab etching. Tom qab ntawd, peb tuaj yeem tso lub substrate rau hauv cov tshuaj electrolyte. Ntawm no, nickel ua raws li anode thaum lub substrate yog cathode. Nickel anode dissolves rau hauv cov tshuaj electrolytic raws li deposition ntawm lub substrate.
Pros and Cons of Nickel Plating
Pros
- tuaj yeem ua tiav txawm tias txheej txheej saum npoo
- Cov cuab yeej ntse tsis tas yuav
- Yooj yim hauv plating ntim thiab tuab
- Tau qhov muag tsis pom qhov nrog lub thickness ruaj khov
- Tau txais qhov ci lossis ib nrab ci tiav
Cons
- Lub neej ntawm txheej yog txwv
- Tus nqi kho mob pov tseg yog siab
- Khw
Qhov txawv ntawm Zinc thiab Nickel Plating yog dab tsi?
Zinc thiab npib tsib xee plating yog hom hlau plating txoj kev peb tuaj yeem siv rau kev kho kom zoo nkauj thiab tiv thaiv qhov chaw ntawm lwm yam hlau. Qhov sib txawv tseem ceeb ntawm zinc thiab npib tsib xee plating yog qhov zinc plating yuav tsum siv cov txheej nyias ntawm zinc ntawm cov khoom siv hluav taws xob thaum cov nickel plating cuam tshuam nrog kev siv cov txheej nyias ntawm nickel rau ntawm cov hlau. Tsis tas li ntawd, lwm qhov sib txawv ntawm zinc thiab npib tsib xee plating yog zinc plating tuaj yeem ua los ntawm kub dip galvanization los yog ntawm txoj kev electroplating thaum npib tsib xee plating feem ntau yog siv txoj kev electroplating.
Tsis tas li ntawd, qhov sib txawv ntawm zinc thiab npib tsib xee plating nyob rau hauv cov nqe lus ntawm lawv qhov zoo thiab qhov tsis zoo yog qhov piv rau cov txheej txheem nickel plating, zinc plating yuav tsum muaj zog tsawg vim tias cov zinc yuav tsum muaj lub zog tsawg. Ntxiv mus, thaum xav txog tus nqi ntawm kev tsim khoom, npib tsib xee plating yog qhov pheej yig vim nws tsis xav tau cov cuab yeej ntse; zinc plating xav tau tus nqi siab rau kev tsim khoom. Txawm li cas los xij, cov khoom tau los ntawm npib tsib xee plating feem ntau kim vim nws qhov ci tiav thiab nws lub peev xwm ua kom qhov muag tsis pom kev ruaj khov.
Cov ntaub ntawv hauv qab no-daim duab qhia txog qhov sib txawv ntawm zinc thiab npib tsib xee plating piv.
Summary – Zinc vs Nickel Plating
Hauv kev xaus, zinc plating thiab npib tsib xee plating yog cov txheej txheem tseem ceeb hauv kev lag luam. Qhov sib txawv tseem ceeb ntawm zinc thiab npib tsib xee plating yog lub hom phiaj ntawm zinc plating yog siv cov txheej nyias ntawm zinc ntawm cov khoom siv hluav taws xob thaum cov nickel plating cuam tshuam nrog kev siv cov txheej nyias ntawm cov npib tsib xee rau ntawm cov hlau.
