Kev kho deg ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov yeeb nkab workpiece
Hais txog kev tshem tawm cov roj stains, xeb, thiab lwm yam rau ntawm qhov chaw ntawm lub workpiece kom lub ntsej muag ntawm lub workpiece huv si thiab tsis muaj cov khoom txawv teb chaws. Qee cov neeg siv tsuas yog yuav tsum tau degreasing lawv qhov chaw kom tshem tawm cov ntsev teev tom qab kev kho cua sov, lossis tsuas yog pickling (xws li tshem cov oxide txheej tom qab stainless hlau argon arc vuam, thiab lwm yam) yam tsis muaj kev ua ntxiv. Feem ntau, ntxuav lub workpiece nto kuj yog ib qho tseem ceeb ua ntej plating txheej txheem rau electroplating.
Tsim cov Electroless Plating Conversion Txheej rau Nqus Electroplating Hluav Taws Kub Kub Tube
Qhov no yog ib txoj kev ua nyob rau hauv uas lub hauv paus los yog txheej hlau koom nyob rau hauv tsim ntawm lwm yam ntaub ntawv ntawm films. Cov txheej txheem hloov pauv tuaj yeem tsim los ntawm cov txheej txheem electrolytic (xws li ntau yam anodic oxidation, AC oxidation, micro-arc oxidation, nyuaj oxidation, thiab lwm yam. ntawm txhuas qhov chaw, electrolytic passivation ntawm silver-plated txheej, electrolytic xim ntawm stainless hlau, thiab lwm yam.) , los yog chemical txoj kev (xws li Blueing, phosphating, blackening ntawm chav tsev kub ntawm steel qhov chaw, passivation ntawm tooj liab qhov chaw, passivation tom qab galvanizing thiab tin plating, thiab lwm yam). Kev hloov pauv txheej txheej tuaj yeem siv los ua ib txheej txheem lossis ua cov txheej txheem tom qab plating.

Cov txheej txheem ntawm kev siv cov tshuaj tiv thaiv tawm mus kom tau ib txheej hlau nyias uas muaj peev xwm zoo dua li cov hlau hauv qab ntawm cov hlau yog hu ua displacement plating, tseem hu ua immersion plating. Xws li tooj liab thiab nickel dipping ntawm steel qhov chaw, zinc thiab zinc alloy dipping ntawm txhuas qhov chaw, nyiaj dipping ntawm tooj liab qhov chaw, thiab lwm yam.
Electroless Plating Electroless Plating rau Nqus Electroplating Hluav Taws Kub Kub Tube
Electroless plating nyob rau hauv uas txo tus neeg sawv cev (xws li formaldehyde, hypophosphite) nws tus kheej yog oxidized los muab cov electrons yuav tsum tau txo cov ntsiab ntsev hlau ions rau hauv hlau atoms hu ua electroless txo plating, los yog electroless plating luv luv. Electroless coatings tuaj yeem yog cov hlau ib leeg (xws li electroless tooj liab), alloys (xws li npib tsib xee-phosphorus), lossis cov txheej txheem sib xyaw. Electroless plating tuaj yeem tau cov txheej tuab dua thiab yog txheej txheem tsis tseem ceeb rau cov hlau tsis yog hlau.
