Keeb kwm ntawm pogo pin electroplating
Electroplating ntawm kub pib nyob rau hauv 1838, tsim los ntawm cov British nyob rau hauv cyanide kub plating, feem ntau yog siv rau kho kom zoo nkauj. Pulse gilding thiab laser gilding tau tshwm sim hauv xyoo 1980s. Electroplating kub yog muab faib ua electroplating nyuaj kub thiab dej kub txheej txheem, lub da dej muaj pes tsawg leeg yog ib txwm zoo ib yam, thiab muaj ib co kab hlau xws li npib tsib xee, cobalt, hlau, thiab lwm yam khoom nyob rau hauv lub hard kub da dej. Tam sim no, Circuit Court board kub plating feem ntau yog citrate kub da dej, uas yog yooj yim los tswj thiab yooj yim rau kev khiav lag luam.
Electroplating kub muaj keeb kwm ntawm ntau tshaj ob puas xyoo. Cov txheej kub plating muaj lub ntsej muag daj daj, muaj tshuaj lom neeg ruaj khov, tsis muaj xim tsis kam, hluav taws xob conductivity, corrosion kuj, thiab oxidation kuj. Ua ke nrog zoo solderability, tsis tshua muaj kev sib cuag tsis kam, thiab zoo heev kub xovxwm bonding muaj nuj nqi, nws ua electroplating kub Cov txheej yuav siv tau raws li ib tug hniav txheej, raws li zoo raws li ib tug haumxeeb thiab tiv thaiv txheej. Yog li ntawd, electroplating kub yog siv nyob rau hauv cov hniav nyiaj hniav kub, phab ntsa moos, handicrafts, electronics, instruments, meters, aviation, aerospace, thiab lwm yam lag luam.
Feem ntau ntawm cov txheej txheem kub electroplating siv muaj cyanide. Cov tsoos cyanide kub plating tov yog ruaj khov thiab txhim khu kev qha, muaj kev ua haujlwm siab tam sim no, muaj peev xwm tawg tau zoo thiab npog muaj peev xwm, thiab cov txheej txheej plating yog cov ncauj lus kom ntxaws thiab ci ntsa iab thiab muaj qhov zoo adhesion. Txawm li cas los xij, cyanide muaj teeb meem rau ib puag ncig thiab tib neeg lub cev. Nrog rau kev nce hauv kev tiv thaiv ib puag ncig, cov tshuaj plating yog tsim nyob rau hauv kev coj ntawm cyanide-dawb thiab kev tiv thaiv ib puag ncig. Cov txheej txheem cyanide-dawb kub plating hloov cov txheej txheem uas muaj cyanide yog cov qauv dav dav.
Cov electroplated kub txheej muaj zog corrosion kuj, zoo hluav taws xob conductivity, yog ib qho yooj yim mus welding, muaj kub-kub kuj, thiab muaj ib tug tej yam hnav tsis kam (xws li tawv kub tov nrog ib tug me me ntawm lwm yam), thiab muaj zoo heev discoloration kuj. . Nyob rau tib lub sijhawm, muaj ntau yam kub alloy coatings Muaj ntau yam ntxoov ntxoo, kub-plated ntawm cov nyiaj tuaj yeem tiv thaiv tsis muaj xim. Electroplating ntawm qhov chaw uas yuav tsum tau muaj kev ruaj ntseg ntev ntawm cov hluav taws xob tsis zoo, xws li cov khoom siv hluav taws xob thiab cov hluav taws xob tiv tauj. Raws li cov txheej txheem kho kom zoo nkauj, kub plating kuj yog siv rau electroplating hniav nyiaj hniav kub, phab ntsa moos, tej hauj lwm ntawm kos duab, thiab lwm yam.
