Lub hom phiaj sib txawv ntawm tooj liab Bar rau Tin Plating, Silver Plating thiab Nickel Plating
May 17, 2022
1. Lub hom phiaj ntawm tin-plated, silver-plated & npib tsib xee-plated
1) Lub hom phiaj ntawm tooj liab tin plating: kom tiv thaiv tooj liab kom tsis txhob ntub thiab ntsuab, thiab tseem tiv thaiv tooj liab oxidation / sulfurization thiab blackening los cuam tshuam hluav taws xob. Lub neej kev pab cuam ntawm tooj liab liab tom qab tin plating yog ncua ob peb zaug los yog kaum zaug, uas zoo heev txhim kho cov kev pab cuam lub neej ntawm liab tooj liab thiab plays ib tug tseem ceeb luag hauj lwm nyob rau hauv kev tiv thaiv ntawm liab tooj liab.
2) Lub hom phiaj ntawm cov nyiaj plating ntawm tooj liab: txhawm rau txhim kho kev sib cuag tiv thaiv thiab txhim kho cov teeb liab kis tau tus mob. (Nyiaj muaj qhov ua tau zoo tshaj plaws, yooj yim rau oxidize, thiab tseem ua hluav taws xob tom qab oxidation).
3) Lub hom phiaj ntawm npib tsib xee plating ntawm tooj liab: rau primer los yog tsos, txhim kho corrosion kuj thiab hnav tsis kam, (tshuaj nickel yog cov cuab yeej niaj hnub uas hnav tsis kam tshaj li ntawm chrome plating).
2. Kev sib piv ntawm thauv plating, nyiaj plating thiab npib tsib xee plating
1) Hardness: Nickel yog ib qho nyuaj tshaj li tin thiab muaj zog khawb kuj.
2) Soldering kev ua tau zoo: tin zoo dua nickel thiab yooj yim rau solder.
3) Corrosion kuj: tag nrho cov kuj zoo, ruaj khov nyob rau hauv cov huab cua. Nws tsuas yog tias qhov kev ua tau zoo ntawm npib tsib xee hauv dilute sulfuric acid yog qhov phem dua li cov tin.
4) Huab cua tsis kam: tin zoo dua nickel.
5) Kho kom zoo nkauj: Nickel yog ci thiab khawb-resistant thiab feem ntau yog siv rau cov hniav electroplating ntawm cov khoom me me, thaum tin feem ntau yog siv rau cov khoom siv hluav taws xob hauv vuam.
6) Cov hluav taws xob conductivity ntawm tin thiab npib tsib xee qis dua tooj liab, thiab qhov sib txawv tsis tseem ceeb. Yog tias koj xav xav txog nws, xav txog tias npib tsib xee yog hlau nplaum, thaum tin tsis yog.
3. Plating
High tin plating tuaj yeem pom los ntawm qhov pom tias cov khoom siv tin plated yog ci dua thiab silvery dawb. Piv nrog rau cov khoom siv npib tsib xee plated, nws yog tsaus dua, thiab cov xim yog tsaus dua los txhim kho kev hnav tsis kam. Thick hard chrome tuaj yeem plated los txhim kho hluav taws xob conductivity. Silver plated, txhawm rau txhim kho kev sib tw, tin lossis txhuas-tin alloy tuaj yeem plated.
The difference in performance between tin plating, nickel plating and chrome plating on the copper surface: the hardness of the coating is chrome plating > nickel plating > tin plating; the appearance brightness (for a long time) is chrome plating > nickel plating > tin plating; chemical stability is nickel plating > chrome plating >Tinned.
Cov nickel-plated txheej muaj siab hardness thiab zoo tshuaj stability, yog li nws yog feem ntau yog vim lub txheej ntawm cov khoom siv hluav taws xob cov khoom siv lead ua;
Cov tin-plated txheej yog mos thiab yooj yim puas, tab sis nws muaj zoo solderability, yog li nws yog feem ntau siv raws li ib tug txheej rau soldering kawg ntawm cov khoom siv hluav taws xob.
Lub hom phiaj tsis yog tsuas yog pab txhawb cov plating tom ntej ntawm lwm cov hlau, tab sis kuj xaiv cov npib tsib xee plating lossis tin plating rau ntau zaus uas muaj zog adhesion thiab hnav tsis kam. Yog tias nws yog ib feem ntawm qhov tsos, feem ntau xaiv cov nickel plating, uas zoo nkaus li zoo thiab tsis hloov xim tom qab ntsuas kub.
