Dab tsi yog qhov txawv ntawm nickel plating ntawm tooj liab thiab tin plating ntawm tooj liab?
Dab tsi yog qhov txawv ntawm nickel plating ntawm tooj liab thiab tin plating ntawm tooj liab?
Muaj nuj nqi: Txhua yam txheej txheej muaj cov txiaj ntsig zoo: lawv tuaj yeem tiv thaiv corrosion (nce antioxidant muaj peev xwm) thiab ua lub luag haujlwm zoo nkauj.
Tooj npib tsib xee plating: Tom qab electroplating, nws muaj tshuaj lom neeg ruaj khov thaum ua haujlwm hauv huab cua thiab alkali daws. Nws tsis yooj yim los hloov xim. Nws yog oxidized tshaj 600 degrees Celsius. Nws muaj siab hardness thiab yooj yim rau polish. Qhov tsis zoo yog porosity. Qhov saum npoo ntawm nickel plating zoo li ci dua. Siv Nws zoo nkaus li tus kov. Nws muaj zog adhesion thiab hnav tsis kam.
Copper tin plating: Nws muaj tshuaj lom neeg ruaj khov, yuav luag insoluble hauv kev daws teeb meem ntawm sulfuric acid, nitric acid, thiab hydrochloric acid, thiab muaj kev vuam zoo. Tin plating tuaj yeem tiv thaiv electromagnetic cuam tshuam. Tin-plated sawv daws saib dawb thiab tsis zoo li ntawd, thiab yuav muaj ib txheej ntawm grey tin ua npuas ncauj thaum kov tes.
Kev siv sijhawm: Nyob ntawm lub sijhawm siv, xaiv cov txheej txheem nickel plating lossis tin plating. 1. Yog tias nws yog ib qho khoom siv sab nrauv, feem ntau yog cov xim nickel plating, vim nws yog du thiab zoo nkauj thiab yuav tsis muaj xim tom qab kev ntsuas kub. 2. Yog hais tias yuav tsum muaj zog conductivity, qhov saum npoo ntawm cov tooj liab yuav tsum yog tin-plated. 3. Yog tias nws yog ib qho khoom siv sab hauv, xws li EMI daim thaiv npog ntawm PCB board, tin plating (chim plating) raug xaiv, thiab qee qhov tseem muaj cov txheej hauv qab plated nrog npib tsib xee ua ntej thiab tom qab ntawd tin plating.
