1. Cov txheej txheem kev txhaj tshuaj hlau
Txheej txheem dej ntws: pretreatment → txau → kom qhuav.
Kev tshaj lij yog ua kom cov zaj duab xis muaj cov nplaum muaj zog, tsis yooj yim kom poob tawm, thiab lub neej ntev. Cov nplaim ntawm seem yuav tsum tau pretreated ua ntej txau. Txawv cov khoom siv hlau qhov sib txawv ntawm txoj kev ua kom zoo tsis yog tib yam. Hlau qhov chaw yog tsuas yog ua rau degreasing, derusting, phosphating thiab lwm yam kev kho mob. Feem ntau siv dej ntxuav cov kua ua kom paug thiab ua kom zoo, siv tshuab lossis tshuaj lom neeg, phosphating yog txhawm rau qhov chaw hauv cov kua qaub (qhov ntuag 1.0 ~ 1.1, pH=1 ～ 3), yuav muaj cov tshuaj tiv thaiv ntawm qhov cuam tshuam ntawm ob. Zaj duab xis phosphate tuab yog tsim nyob rau saum npoo ntawm ntu txhawm rau txhim kho kev nplaum thiab xeb tsis kam ntawm cov xim pleev xim. Aluminium thiab nws cov khoom siv txhuas yog feem ntau kho nrog degreasing thiab deoxidizing zaj duab xis. Cov txheej txheem degreasing yog tib yam li cov hlau ntawm qhov chaw. Cov oxide zaj duab xis tau muab tshem tawm los ntawm pickling, thiab tom qab ntawd tom qab ntawd hloov cov tshuaj lom neeg yog siv los ua cov hloov pauv zaj duab xis. Yog hais tias qhov saum npoo uas xav tau ntawm qhov tsis siab, nws tuaj yeem raug cais tawm. Conversion ua.
Cov txheej txheem txau thiab cov txheej txheem sib txawv kuj sib txawv raws li ntau yam, kev ua haujlwm thiab kho kom zoo ntawm txheej. Muaj ntau lub xim pleev xim xws li roj pleev xim, ntuj cob, epoxy resin, phenolic resin, thiab lwm yam, uas tuaj yeem xaiv raws li cov xwm txheej tseeb. Muaj ntau txoj hauv kev rau txau, xws li phau ntawv, tsis siv neeg, electrostatic, electrophoresis, thiab lwm yam, uas tuaj yeem xaiv raws li cov kab ntau, cov duab thiab cov qhov loj me ntawm cov seem thiab cov khoom siv uas twb muaj lawm.
Kev hnav ntawm feem yuav ua rau tag nrho cov txheej txheem ua haujlwm tsis meej, thiab cov tshuaj tsuag txau siv tau rov qab siv dua. Piv txwv li, lub kinescope Hoobkas tau tuaj yeem kwv yees ze li ntawm 10,000 yuan ntawm vibrating feeder los ntawm Nyij Pooj. Daim disk saum npoo yog ua los ntawm cov ntawv txhuas me me, nrog lub taub txog li 500-600 hli. Vim tias siv ntev ntev, cov khoom siv taug txoj hauv kev hnyav hnav thiab khawb tau pom thiab tsis tuaj yeem ua haujlwm ib txwm. Qhov kev daws teeb meem tau daws sai thiab zoo tom qab txau nrog cov tshuaj pleev kom yooj yim-polyamide epoxy cob.
2. Lub phiaj xwm tshwj xeeb muaj raws li hauv qab no:
Txog rau kev ntsuas ua ntej, siv trichloroethane los ntxuav cov roj ntawm qhov chaw ntawm daim disk, thiab tom qab ntawd mam li tsau rau hauv nitric acid rau li 30 feeb. Tsuas yog yaug tawm xwb.
Siv cov ntaub nplaum los tiv thaiv qhov chaw uas tsis tau txau, thiab muab lub phaj vibrating kab rov tav rau ntawm cov khoom siv tiv thaiv (ntawv, ntaub, thiab lwm yam) los tiv thaiv cov xim txaws.
Cov khoom xyaw muaj raws li hauv qab no: 6101 epoxy resin 1kg, 650 polyamide 0.5kg, chromium oxide 0.2kg, ib qho me me ntawm talc, sib tov + meej ethanol even do tusyees.
Siv phom xuas phom los tsuag. Txhawm rau kom ntseeg tau tias cov txheej yog txawm thiab du, cov phom xuas phom thiab cov xim tawm yuav tsum tau kho. Nyob rau tib lub sijhawm, qhov kev ncua deb ntawm rab phom thiab daim disk saum npoo yog khaws cia ntawm 300-500 hli, thiab cov tshuaj txau tau ua nyob rau hauv peb zaug, thiab txheej yuav zoo li yam tsis sib thooj. Kom qhuav, ntuj qhuav yuav siv li 24h; thaum qhov ntsuas cua kub kom sov yog 100 ℃, nws yuav siv li 1.5 ～ 2.0h.
Qhov saum npoo ntawm daim disk tom qab txau tshuaj yog sib xws thiab du, thiab cov nyhuv yog qhov zoo ntawm qhov chaw, thiab nws tuaj yeem siv txuas ntxiv rau 8-12 lub hlis.
3. Xaus lus
Nws yog yig thiab siv tswv yim los kho cov hlau coj qhov chaw nrog cov xim pleev xim, uas qhib txoj kev tshiab rau kev kho cov khoom saum npoo ntawm cov hlau.
