1.Yuav ua li cas ntxuav lub substrate?
Ua ntej-kev kho mob (Degreasing): Txias- cov nplooj ntawv steel feem ntau muaj cov roj stamping, xeb-cov roj tiv thaiv, thiab plua plav ntawm lawv qhov chaw. Cov no yuav tsum tau muab tshem tawm kom huv si los ntawm kev ua ntej -degreasing thiab cov txheej txheem degreasing tseem ceeb. Kev lag luam, alkaline degreasing cov neeg ua haujlwm feem ntau yog siv ua ke nrog tshuaj tsuag lossis tso rau hauv dej, nrog rau qhov ntsuas kub ntawm kwv yees li 45-55 degree.
Kev tshem tawm xeb: Yog tias lub tshuab ua haujlwm twb xeb lawm, nws yuav tsum tau muab tshem tawm cov xeb ua ntej kho. Rau cov kab ntau lawm, nws yog feem ntau tsis pom zoo kom siv cov kua qaub uas muaj zog rau xeb tshem tawm hauv online, vim tias cov kua qaub tuaj yeem ua rau cov khoom siv corrode thiab cuam tshuam rau cov kev daws teeb meem tom qab da dej. Rusty workpieces yuav tsum tau kho nyias ua ntej mus online.
Kev Ntxuav Dej: Tom qab degreasing, lub workpiece yuav tsum tau muab yaug nrog dej (feem ntau yog dej kub thiab txias) kom tshem tawm cov seem alkali thiab surfactants. Ib qho yooj yim soj ntsuam tus qauv yog tias cov yeeb yaj kiab dej ntawm qhov chaw ua haujlwm rinsed yuav tsum tsis tu ncua thiab zoo ib yam, tsis muaj cov tee dej dai, qhia tias cov roj tau raug tshem tawm tag nrho.
2.Dab tsi yog cov kauj ruam koom nrog hauv kev tsim cov yeeb yaj kiab tshuaj?
Txheej Txheem: Phosphating
Deg Conditioning: Ua ntej phosphating, lub workpiece feem ntau dhau los ua "surface conditioning", kho nrog cov tshuaj colloidal titanium. Lub hom phiaj yog ua kom cov crystals uas ua los ntawm cov phosphating tom qab finer, txhim kho txheej txheej.
Phosphating: Lub workpiece yog immersed nyob rau hauv ib tug phosphate tov, tsim ib tug insoluble phosphate (xws li zinc phosphate) chemical zaj duab xis ntawm nws nto. Cov yeeb yaj kiab no yog ntxeem tau thiab txhim kho cov txheej txheej adhesion thiab corrosion kuj. Qhov kub phosphating feem ntau yog nyob ib ncig ntawm 30-35 degree.
Environmentally Friendly New Txheej Txheem: Silane Treatment
Qhov no yog ib qho tseem ceeb ntawm ib puag ncig tus phooj ywg thev naus laus zis hauv xyoo tas los no, feem ntau siv los hloov cov tshuaj phosphating. Nws siv cov silane coupling tus neeg sawv cev los teb rau cov phaj hlau ntawm qhov kev kho qhov kub thiab txias (RT, piv txwv li, chav tsev kub) los ua ib qho tsis tshua muaj nyias, ntom ntom nanoscale organic-inorganic hybrid zaj duab xis. Silane kev kho mob yuav tsum tsis muaj cua sov, ua kom tsis muaj hlau sludge hnyav, muaj lub sijhawm luv luv, thiab muaj qhov zoo ntawm ib puag ncig zoo.
Cov txheej txheem yuav tsum tau ua: Cov yeeb yaj kiab silane yuav tsum tsis sib xws thiab tsis zoo, nrog rau qhov zoo feem ntau yuav tsum tsis pub tsawg dua 0.1 g / m².
3.Lub luag haujlwm ntawm kev tshaj tawm yog dab tsi?
Tom qab tsim cov yeeb yaj kiab tshuaj, qhov chaw ua haujlwm yuav tsum tau muab yaug kom huv si nrog dej huv (xws li dej deionized lossis dej ntshiab) kom tshem tawm cov tshuaj seem thiab tiv thaiv cov cim ntws los yog cuam tshuam tsis zoo rau txheej txheej.
4.Dab tsi yog dej tshuab thiab ziab?
Tom qab ntxuav, lub workpiece yuav tsum tau mus rau lub tshuab nqus dej kom tshem tawm cov dej pom tseeb ntawm qhov chaw, thiab tom qab ntawd nws raug xa mus rau qhov cub kom qhuav. Kev ziab kom qhuav yog feem ntau tswj ntawm ib ncig ntawm 120 degree, lub hom phiaj yog tshem tawm tag nrho cov dej noo los ntawm cov crevices ntawm lub workpiece thiab npaj rau cov kauj ruam tom ntej ntawm kev txau.
5.Dab tsi yog cov kauj ruam ua ntej kom txias - dov coils ua ntej txau?
Cov txheej txheem pretreatment rau txias- dov coil txheej tuaj yeem muab sau ua cov txheej txheem nruj los ntawm "huv" mus rau "zaj duab xis" thiab tom qab ntawd mus rau "qhuav". Kev xaiv ntawm cov txheej txheem phosphating ib txwm muaj thiab cov txheej txheem silane ib puag ncig feem ntau yog nyob ntawm koj qhov kev xav tau ib puag ncig, kev siv nyiaj txiag, thiab cov cim qhia tshwj xeeb rau txheej txheej (xws li lub sijhawm tshuaj tsuag ntsev).
