Hauv cov tshuaj tsw qab ntim lossis ntim cov tshuaj pleev ib ce indutry, yas yog siv dav ua cov khoom ntim. Xws li cov kaus mom naj hoom, naj hoom xub pwg ntu, qhov chaw ua kom zoo nkauj naj hoom los yog qee yam pleev plhu. Kev kho saum npoo yog feem ntau plating, piv nrog cov khoom siv hlau, cov khoom siv hluav taws xob yas tsis tuaj yeem tsuas yog ua tiav cov hlau zoo, tab sis kuj ua kom pom qhov hnyav ntawm cov khoom, zoo txhim kho qhov zoo thiab kho kom zoo nkauj ntawm plastics, lawv kuj txhim kho kev ua haujlwm ntawm hluav taws xob, cua sov thiab kev txhim kho corrosion raws li kev txhim kho cov tsos thiab kho kom zoo nkauj ntawv.
Muaj ob qho txheej txheem electroplating rau cov khoom yas: galvanic plating (Galvanic deposition) thiab nqus ion plating (Lub tshuab nqus plating).
Galvanic plating:
Nws yog feem ntau haum rau cov khoom siv ABS thiab ABS + PC khoom siv. Cov txheej txheem loj yog electroplating hauv kev siv tshuaj electroplating kua uas yuav tsum tau electroplated. Cov xim sib txawv tuaj yeem plated raws li qhov xav tau sib txawv ntawm cov neeg yuav khoom, kub, nyiaj, chrome, npib tsib xee, tooj thiab ob peb lwm cov xim hlau.
Nqus plua plav ion plating, tseem hu ua txheej nqus tsev:
Lub tshuab nqus plating yog muaj ntau qhov kev siv, xws li ABS, ABS + PC thiab PC khoom siv. Tab sis vim tias nws cov txheej txheem nyuaj, kev xav tau ntawm ib puag ncig thiab cov cuab yeej siv, tus nqi ntawm lub tshuab nqus plating yog siab dua galvanic plating.
Cov txheej txheem luv luv ntawm lub plua plav plating yog "saum npoo tu & tshem tawm hluav taws xob zoo li qub" - "txheej txheej" - "ci hauv paus txheej" - "nqus xau" - "txau xim" - "ci xim ua tiav" - "pob" .Vav plating tuaj yeem faib mus rau hauv dav dav plating, UV nqus plating, thiab lub tshuab nqus plating tshwj xeeb. Cov txheej txheem muaj chav plating, txaws, phom plating plating thiab lwm yam.
Qhov sib txawv ntawm galvanic plating thiab nqus plating:
Galvanice plating yog siv dav vim tias cov txheej txheem yooj yim thiab tsis muaj ib qho nruj ntawm cov khoom siv thiab ib puag ncig piv nrog nqus plating. Txawm li cas los xij, muaj qhov tsis muaj zog ntawm galvanice plating, uas tuaj yeem tsuas ua tau plating ABS thiab ABS / PC khoom. Qhov kub ntawm ABS tsuas yog 80 degree, uas txwv nws daim ntawv thov. Thaum lub tshuab nqus plating tuaj yeem ncav cuag li 200 degrees C, uas tuaj yeem plated rau cov Cheebtsam siv hauv qhov kub. Rau lub plua plav plating, txheej txheej ntawm UV roj yuav tsum tau muab txau thaum kawg, thiaj li hais tias cov nplaim ntawm cov khoom yog gloosy, siab kub tsis kam thiab lub zog adhesion.
Qhov zoo thiab qhov tsis zoo ntawm galvanic plating thiab nqus plating:
1. Yog tias tsis muaj UV roj txau, lub zog lo nplaum tsis zoo, cov khoom lag luam tsis tuaj yeem hla Adhesion Hla-Txiav Xeem. Galvanic plating tau zoo dua rau ntawm qhov point no.Yog li ntawd, txhawm rau xyuas kom lub zog adhesion ntawm lub tshuab nqus plating, qhov tshwj xeeb UV roj txau txheej txheem yuav tsum tau ua, tab sis qhov no yuav increse tus nqi ntawm chav kawm.
2. Tsuas muaj ob peb xim muaj peev xwm ua tau los ntawm cov ntawv galvanic plating, xws li kub, nyiaj, tooj. Thaum lub tshuab nqus tsev plating tuaj yeem ua ntau yam xim.
Plated yas muab ntau cov qauv thiab cov tsos zoo nkauj rau cov naj hoom ntim khoom. Cov thawj coj ua ntau yam ntawm lub hau yas thiab naj hoom fwj nrog cov txheej txheem sib txawv raws li koj tus qauv tsim thiab cov khoom lag luam, txais tos hu rau peb kom paub ntau ntxiv.
