Ntau hom hlau plating

Hlau plating yog txheej txheem uas yuav tso ib txheej ntawm cov hlau mus rau saum npoo ntawm lwm cov khoom. Qhov no yog ua rau ntau lub hom phiaj, suav nrog kev txhim kho cov tsos, txhim kho corrosion kuj, muab kev hnav tsis kam, thiab ua kom zoo dua conductivity. Muaj ntau ntau hom hlau plating txheej txheem, txhua tus nrog nws cov kev siv tshwj xeeb thiab qhov zoo. Nov yog qee yam ntawm ntau hom:

Electroplating: Electroplating yog cov txheej txheem siv hlau plating tshaj plaws. Nws suav nrog kev tso cov khoom kom tau plated (lub substrate) rau hauv cov tshuaj uas muaj hlau ions ntawm cov khoom siv plating. Ib qho hluav taws xob ncaj qha tau dhau los ntawm kev daws teeb meem, ua rau cov hlau ions ua raws li cov txheej txheem substrate, tsim cov txheej txheem sib xws thiab cov txheej txheem hlau. Electroplating yog siv nyob rau hauv ntau yam kev lag luam, xws li tsheb, hluav taws xob, thiab cov hniav nyiaj hniav kub, rau kev kho kom zoo nkauj thiab ua haujlwm.

Electroless Plating: Tsis zoo li electroplating, electroless plating tsis xav tau hluav taws xob sab nraud. Hloov chaw, tshuaj lom neeg cov tshuaj tiv thaiv ntawm tus neeg sawv cev txo qis thiab cov hlau ions hauv kev daws teeb meem tso cov hlau mus rau lub substrate. Electroless plating yog paub txog nws lub peev xwm los coated complex duab thiab tsis-conductive nto. Nws yog feem ntau siv rau hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs) thiab hauv kev lag luam uas yuav tsum muaj kev tswj xyuas qhov tuab.

Immersion Plating: Immersion plating yog ib txoj hauv kev yooj yim uas cuam tshuam rau cov substrate hauv cov tshuaj uas muaj cov ntsev ntsev. Cov hlau ions nyob rau hauv cov tshuaj ua raws li lub substrate nto, tsim ib txheej nyias ntawm cov hlau xav tau. Cov txheej txheem no feem ntau yog siv rau cov ntawv thov me me thiab ua ntej kev kho mob hauv lwm cov txheej txheem plating.

Vacuum Deposition (PVD thiab CVD): Lub cev Vapor Deposition (PVD) thiab Chemical Vapor Deposition (CVD) yog cov txheej txheem siv los tso cov yeeb yaj kiab hlau nyias mus rau cov khoom siv hauv lub tshuab nqus tsev. PVD cuam tshuam cov vaporization ntawm cov hlau nyob rau hauv lub tshuab nqus tsev chamber, ua raws li nws cov deposition mus rau lub substrate nto. CVD, ntawm qhov tod tes, siv tshuaj lom neeg los tsim cov txheej txheem hlau. Cov txheej txheem no yog ua haujlwm nyob rau hauv kev lag luam semiconductor, optics, thiab cov txheej txheem zoo nkauj.

Anodizing: Anodizing yog ib hom electrochemical plating siv feem ntau ntawm txhuas thiab nws cov alloys. Nws koom nrog tsim cov txheej txheem oxide tswj ntawm cov hlau saum npoo. Anodizing muab kev txhim kho corrosion, txhim kho hnav tsis kam, thiab tuaj yeem siv rau kev kho kom zoo nkauj.

Galvanization: Galvanization koom nrog txheej hlau lossis hlau nrog txheej zinc los tiv thaiv corrosion. Txoj kev siv ntau tshaj plaws yog kub-dip galvanization, qhov twg lub substrate yog immersed nyob rau hauv molten zinc. Galvanization yog dav siv hauv kev tsim kho thiab kev lag luam tsheb.

Tin Plating: Tin plating yog siv los tiv thaiv corrosion, txhim khu kev lag luam, thiab muab lub ci ci zoo nkauj. Nws yog feem ntau siv hauv kev lag luam ntim khoom noj (tin poom) thiab khoom siv hluav taws xob.

Kub Plating: Kub plating muab zoo heev corrosion kuj, hluav taws xob conductivity, thiab aesthetic thov. Nws yog feem ntau siv hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog rau cov khoom sib txuas thiab kev sib cuag.

Chrome Plating: Chrome plating paub txog nws cov khoom zoo nkauj thiab corrosion-resistant. Nws yog feem ntau siv nyob rau hauv lub tsheb thiab chav dej fixture industries.

Txhua hom hlau plating muaj nws qhov zoo thiab cov kev siv tshwj xeeb, ua rau lawv cov txheej txheem tseem ceeb hauv ntau yam lag luam. Kev xaiv ntawm txoj kev plating nyob ntawm qhov xav tau ntawm cov khoom tiav thiab cov ntaub ntawv koom nrog.
