Electroplating yog txoj kev kho hluav taws xob uas hlau ions hauv kev daws teeb meem yog muab tso rau qhov chaw ruaj khov chaw siv hluav taws xob. Cov txheej txheem no ua ib qho nyias nyias, txawm tias txheej hlau ntawm cov khoom, uas txhim kho nws cov khoom lossis muab nws ua kom zoo nkauj tiav.
Cov khoom yuav tsum tau plated yog hu ua substrate, thiab nws ua raws li cathode (tsis zoo davhlau ya nyob twg) nyob rau hauv electrochemical cell. Ib daim hlau, uas yuav ua txheej txheej, ua haujlwm ua anode (qhov chaw zoo). Ob qho tib si muab tso rau hauv cov da dej electrolytic muaj cov ntsev cov ntsev. Thaum hluav taws xob tau siv, hlau ions txav los ntawm kev daws thiab txuas mus rau saum npoo ntawm substrate.
Cov ntaub ntawv dab tsi yuav yog electroplated?
Electroplating tuaj yeem siv rau ntau cov ntaub ntawv, suav nrog:
- Cov hlau (xws li tooj liab, npib tsib xee, zinc, chromium)
- Yas Ncig (Tom qab kev kho mob los ua kom lawv ua tiav)
- Cov khoom sib dhos muaj tej hub (hauv qee cov ntawv thov siab)
Cov khoom siv hauv paus xws li yas, hlau, tooj dag, thiab txhuas. Cov khoom siv me me yuav suav nrog kub, nyiaj, npib tsib xee, lossis chromium, nyob ntawm daim ntawv thov.
Cov txiaj ntsig tseem ceeb ntawm Electroplating
- Txhim kho tsos
Muab cov nthwv dej ib qho ci, ci, lossis nws yog xim hlau.
- Corrosion Kuj
Tiv thaiv cov khoom siv hauv qab los ntawm oxidation thiab hnav.
- Nce saum tawv tawv
Ntxiv cov txheej nyuaj kom txo cov khawb thiab kev puas tsuaj saum npoo.
- Hluav Taws Xob Kev Tshaj Tawm
Txhim kho qhov kev ua haujlwm ntawm cov khoom siv hauv cov khoom siv hluav taws xob.
- Tus Nqi Muaj Zog
Siv cov hlau tsis tshua muaj nqi thaum ua tiav qhov kev xaus siab.
Puas muaj hluav taws xob kev nyab xeeb rau cov khoom noj khoom haus thiab kev noj qab haus huv ntim?
Yog lawm-yog cov khoom noj cov zaub mov thiab cov txheej txheem tsim nyog. Rau cov ntawv thov xws li cov zaub mov lossis cov khoom siv tau, tsuas yog cov qauv tsis muaj tshuaj lom thiab cov txheej txheem muaj ntawv pov thawj yuav tsum tau siv los ntawm cov ntsiab lus.

Electroplating yog cov txheej txheem pov thawj rau kev txhim kho cov tsos thiab ruaj khov ntawm ntau yam khoom. Txawm hais tias siv rau kev kho kom zoo nkauj, ua haujlwm, lossis cov laj thawj tiv thaiv, nws ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub no. Los ntawm kev nkag siab tias nws ua haujlwm li cas, cov lag luam tuaj yeem txiav txim siab tau zoo dua thaum xaiv cov khoom hauv lawv cov khoom lag luam.
