Lub adhesion ntawm lub tshuab nqus tsev plating hluav taws xob cua sov raj hlau ci xim tsis zoo
Qhov saum npoo ntawm zinc alloy substrate tsis zoo adhesion rau hlau ci xim. Feem ntau, qhov saum npoo yog pretreated los ua ib zaj duab xis hloov dua siab tshiab rau ntawm qhov chaw los txhim kho qhov adhesion ntawm cov xim txheej ntawm cov hlau, thiab qhov kev sim hla ntuag adhesion yog nqa tawm. Thaum lub adhesion zoo heev, nws ncav cuag 5B. Nyob rau tib lub sij hawm, nws cov corrosion kuj thiab ntsev tsuag kev ua tau zoo kuj zoo heev.
Nqus electroplating hluav taws xob cua sov raj zinc alloy txau xim
Zinc alloy tshuaj tsuag xim yog cov txheej txheem kev kho hlau zoo heev. Los ntawm cov xim pleev xim, cov xim zoo nkauj zaj duab xis txheej tuaj yeem tau txais, uas tuaj yeem txhim kho nws cov kev tiv thaiv corrosion, kev ua haujlwm zoo nkauj thiab kev lag luam. Nyob rau hauv cov txheej txheem tshuaj pleev xim ntawm zinc alloy, daim ntawv thov ntawm cov hlau adhesion kho tus neeg saib xyuas yog los xyuas kom meej cov txheej txheem zoo, thiab muab cov kev daws teeb meem raws sij hawm thiab siv tau zoo thaum cov zinc alloy spray xim tsis zoo adhesion thiab cov xim poob.

Daim ntawv thov ntawm cov hlau adhesion kho tus neeg saib xyuas kuj yuav tsum tau ua raws li cov txheej txheem ntau lawm. Yog tias cov xim pleev xim aluminium alloy yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev kho kom zoo, ntxiv rau kev xaiv cov xim thiab cov txheej txheem kev kho mob, qhov tsim nyog pretreatment yog tshem tawm cov roj los ntawm aluminium alloy nto. Raws li kev kho mob xws li kev tshem tawm plua plav, yog tias tsis ntxuav, qhov adhesion ntawm cov xim yuav raug txo qis, ua rau muaj teeb meem ntawm cov xim tev, thiab gloss thiab hardness ntawm cov xim txheej yuav txo.

Daim ntawv thov ntawm cov hlau adhesion kho tus neeg sawv cev hauv txheej txheej txheej yog sib npaug rau kev tsim cov primer. Los ntawm txau ib txheej ntawm cov hlau adhesion kho tus neeg sawv cev ntawm aluminium alloy substrate thiab tom qab ntawd txau cov xim, qhov sib txuas ntawm qhov sib txuas ntawm cov substrate thiab cov xim zoo tuaj. Nws muaj qee cov yeeb yaj kiab tuab, uas tuaj yeem txhawb nqa qhov adhesion ntawm cov xim, thiab daws qhov teeb meem ntawm aluminium alloy spray xim poob tawm yam tsis tau hloov qhov kev ua tau zoo thiab kev kho deg ntawm cov xim. Tus nqi txau yog feem ntau tswj ntawm 3-5μm. Cov nyhuv yog qhov zoo dua, haum rau cov tshuaj tsuag tes thiab tsis siv neeg xov.
