Cov khoom ntawm cov khoom sib txawv ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj kuj muaj qhov sib txawv

Tsis zoo electroplating kuj muaj qhov sib txawv ntawm cov khoom ntawm cov khoom sib txawv. Piv txwv li, cov khoom siv kho kom zoo nkauj tsis zoo tuaj yeem ua rau cov khoom tsis zoo li qhov xav tau, tab sis tsis ua haujlwm tsis zoo. Txawm li cas los xij, kev ua haujlwm tsis zoo ntawm qhov chaw xa mus rau qhov corrosion ntawm lub substrate ntawm cov khoom siv thaum lub sij hawm siv cov khoom, uas tsis pub muaj nyob rau hauv tej qhov chaw-kho qhov chaw.

Nyob rau hauv lub tshuab nqus tsev, cov atoms thiab molecules ntawm cov khoom evaporated muaj tsawg dua kev sib tsoo nrog lwm cov molecules nyob rau hauv tus txheej txheem ntawm ya mus rau cov khoom yas, thiab lawv cov kev ua nyob rau hauv cov roj yog txo. Cov tshuaj tiv thaiv ntawm cov molecules thiab cov khoom siv evaporation los muab qhov ceev, purity, deposition npaum li cas thiab adhesion ntawm zaj duab xis.

Nqus electroplating hluav taws xob cua sov raj los kho lub sij hawm evaporation

Vim tias qhov saum npoo ntawm cov yas tsis du txaus, qhov chaw ntawm lub workpiece ncaj qha electroplated tsis du, gloss yog tsawg, cov hlau tsis zoo, thiab qee qhov tsis zoo xws li huab cua npuas thiab hlwv yuav tshwm sim. Tom qab txau ib txheej ntawm primer, ib tug du thiab tiaj tus nto yuav tsim, tshem tawm cov tiam ntawm huab cua npuas thiab hlwv nyob rau hauv cov yas nws tus kheej, yog li qhia cov nyhuv ntawm electroplating.

Lub tshuab nqus tsev electroplating yog ib txoj kev ua kom sov cov hlau nyob rau hauv lub tshuab nqus tsev siab, melting thiab evaporating nws, thiab tsim ib zaj duab xis hlau rau ntawm cov yas tom qab txias. Txoj kev ua kom sov hlau yog siv cov cua sov uas tsim los ntawm hluav taws xob tsis kam. Yog, qee qhov siv cov kab hluav taws xob. Nyob rau hauv cov txheej txheem evaporation ntawm cov khoom yas, txhawm rau kom ntseeg tau tias cov cua sov tso tawm thaum cov hlau txias yuav tsis deform cov resin, lub sij hawm evaporation yuav tsum tau kho.

Cov khoom siv tshuaj xyuas yooj yim ntawm cov khoom siv electroplated ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj muaj xws li:

Electroplating txhais tau hais tias nyob rau hauv cov ntsev tov uas muaj pre-plated hlau, lub hauv paus hlau yuav tsum tau plated yog siv raws li cathode, thiab los ntawm electrolysis, cov cations ntawm pre-plated hlau nyob rau hauv lub plating tov yog tso rau saum npoo ntawm lub hauv paus hlau. los tsim ib txheej plating, kom cov khoom electroplated tuaj yeem tiv thaiv corrosion thiab txhim kho kev tiv thaiv. Ib txoj kev kho deg rau abrasive tsis kam, kub tsis kam thiab txhim kho kev zoo nkauj.

Cov khoom kuaj xyuas yooj yim ntawm cov khoom siv electroplated muaj xws li: zaj duab xis thickness, adhesion, solderability, tsos, ntim, ntsev tsuag tshuaj ntsuam, thiab lwm yam. Nqus plating yog kev xyaum ntawm spraying primer rau cov khoom ua ntej plating. Txij li cov khoom siv yog yas, yuav muaj cua npuas nyob rau hauv lub tshuab roj thaum lub sij hawm txhaj tshuaj molding txheej txheem, thiab noo noo nyob rau hauv cov huab cua yuav absorbed thaum muab tso rau.
