Electrophoresis EP Electrophoresis Painting Kab
Kev piav qhia yooj yim
Electrophoretic xim (E Coat) yog tam sim no qhov kawg ntawm kev xaiv hauv kev lag luam tsheb uas yuav tsum muaj kev tiv thaiv corrosion siab ntawm cov khoom siv hauv qab. Qhov no feem ntau nyob deb dua thiab muaj tus nqi qis dua rau cov hmoov txheej thiab tau dhau los ua neeg nyiam dua yog cov kev lag luam lossis cov khw muag khoom siv uas yuav tsum muaj kev tiv thaiv corrosion siab thiab ua kom zoo nkauj tiav.
E-coat Epoxy Hom (electrophoretic painting) muaj kev tiv thaiv corrosion siab, feem ntau dhau ntawm 1000 xuab moos ntsev tshuaj tiv thaiv nrog rau qhov zoo nkauj zoo nkauj.
Thaum siv rau cov txheej txheem xws li phosphate, zinc lossis zinc-nickel, corrosion kuj tuaj yeem nce ntxiv. Tsis tas li ntawd, tsis zoo li cov tshuaj tsuag lossis dipped coatings E-coat tiav muab cov txheej txheem sib txawv ntawm cov txheej txheem tag nrho tsis hais qhov nyuaj ntawm cov khoom. Qhov saum npoo tiav no muab cov tawv tawv ua ke nrog cov tshuaj tiv thaiv zoo muab cov khoom siv zoo heev thiab yog lwm txoj hauv kev zoo rau cov hmoov txheej rau ntau daim ntawv thov.
Cov neeg muag khoom thoob ntiaj teb tseem ceeb ntawm tsheb ecoat KTL yog PPG Kev Lag Luam Tebchaws USA, BASF Lub Tebchaws Yelemees, Hawking Electro thev naus laus zis UK, DuPont, Frei Lacke Freiotherm thiab Henkel.
Electrophoretic e-coat cov neeg siv khoom niaj hnub no hais kom zoo thiab ua haujlwm ntev los ntawm cov khoom uas lawv them nyiaj rau. Lawv thov kom cov khoom no yuav tsum ua tau zoo, tab sis lawv xav kom qhov ua tiav kom zoo zoo thiab tiv thaiv corrosion rau lub sijhawm ntev dua. Cov txheej txheem tiav los ntawm Electrophoretic txheej yog tsim los ua qhov ntawd. Lub npe nrov rau cov txheej txheem tiav yog KTL, Electrophoretic lacquer, Electrodeposition, Electro-coating, Cathodic dip-painting (CDP) thiab e-coating.
Khoom Qhia
Cov txheej txheem
Kev kho mob ua ntej | Ntxuav thiab phosphate hlau los npaj qhov chaw rau e-txheej txheej. Kev tu thiab phosphating yog qhov tseem ceeb rau kev ua tiav cov kev xav tau uas xav tau los ntawm cov neeg siv khoom niaj hnub no. Peb txheeb xyuas cov hlau kom ua tiav thiab xaiv cov tshuaj tsim nyog tshaj plaws. Ib qho zoo zinc phosphate system siv txoj kev immersion feem ntau yog siv nyob rau hauv peb lub tshuab uas cov hlau thiab hlau yuav tsum tau coated. |
Electro-coating | Qhov twg siv cov txheej txheem thiab cov txheej txheem tswj cov cuab yeej ua haujlwm. Lub e-coat da dej muaj 80-90% deionized dej thiab 10-20% xim khib nyiab. |
Post Rinses | Muab ob qho tib si zoo thiab kev txuag. Thaum lub sij hawm e-coat txheej txheem, cov xim yog siv rau ib feem ntawm ib co zaj duab xis thickness, tswj los ntawm tus nqi ntawm voltage thov. Thaum cov txheej txheem mus txog qhov xav tau zaj duab xis thickness, ib feem insulates thiab txheej txheem txheej slows down. Raws li ib feem tawm ntawm lub da dej, cov xim pleev xim rau ntawm qhov chaw thiab yuav tsum tau muab yaug tawm kom muaj txiaj ntsig zoo thiab zoo nkauj. Cov xim pleev xim ntau dhau yog hu ua "drag out" lossis "cream coat." Cov xim pleev xim ntau dhau tau xa rov qab mus rau lub tank los tsim cov txheej txheem kev ua haujlwm siab tshaj 95%. |
Ci Qhov cub | Tau txais cov khoom tom qab lawv tawm ntawm tus ncej yaug. Lub qhov cub ci hla kev sib txuas thiab kho cov xim zaj duab xis kom paub tseeb tias qhov ua tau zoo tshaj plaws. |
