Daim ntawv thov thiab kev loj hlob ntawm Cathodic Electrophoretic txheej rau hluav taws xob cua sov Tube Electroplating

Cathodic electrophoretic coatings yog dav siv nyob rau hauv cov hlau nto txheej kev kho mob vim lawv cov huab cua tsis kam, siab durability, siab transparency, zoo zoo nkauj zog, ib puag ncig tiv thaiv, kev ruaj ntseg, thiab tsis corrosiveness ntawm cov hlau substrate. Kab lus no muab cov ntsiab lus ntawm txoj kev loj hlob ntawm cathodic electrophoretic txheej ob qho tib si hauv tsev thiab thoob ntiaj teb, thiab qhia ntau yam tshwj xeeb cathodic electrophoretic txheej, xws li UV curable electrophoretic coatings thiab tus kheej txheej txheej polar electrophoretic txheej. Electrophoretic coatings originated nyob rau hauv 1930s thiab pib tshawb fawb thiab synthesizing cationic resins nyob rau hauv nruab nrab -1960s. Lawv tau siv los ua primers ntawm cov khoom siv hauv tsev nrog cov kev xav tau siab rau kev tiv thaiv corrosion thaum ntxov xyoo 1970s. Tom qab ntawd, cathodic electrophoretic txheej nrog ntau dua corrosion kuj thiab cov teebmeem zoo nkauj tau maj mam tsim. Vim lawv cov corrosion kuj zoo heev, siab permeability, siab leveling, siab kho kom zoo nkauj, thiab high degree ntawm txheej automation Cov txheej muaj cov yam ntxwv ntawm cov pa phem thiab yog dav siv nyob rau hauv lub tsheb lub tsheb kev lag luam, thiab yog txhawb kom siv nyob rau hauv industrial teb xws li. raws li cov khoom siv hauv tsev, lub teeb kev lag luam, cov khoom siv hauv tsev, nrog rau qhov chaw tiv thaiv corrosion thiab kho kom zoo nkauj ntawm cov khoom siv thiab cov khoom siv tes ua.

Cov yam ntxwv ntawm Cathodic Electrophoresis

1) Piv nrog cov tshuaj hnyav raws li cov txheej txheem thiab lwm yam immersion thiab tshuaj tsuag dej-raws li ci xim, cathodic electrophoretic txheej muaj qhov zoo sib xws: cov txheej txheem primer tuaj yeem ua tiav thiab tsim nyog rau cov khoom loj; Uniform zaj duab xis thickness tuaj yeem tau txais; Zoo permeability txhim kho corrosion kuj ntawm lub puab kab noj hniav ntawm lub workpiece, tshwj xeeb tshaj yog corrosion kuj ntawm cathodic electrophoretic txheej zaj duab xis; Kev siv ntau ntawm cov coatings; Kev nyab xeeb siab, xim tsis muaj kuab lom; Cov tsos ntawm txheej yog zoo, thiab nws muaj zoo flatness thaum qhuav.

2) Muab piv nrog cov txheej txheem anodic electrophoretic txheej, nws muaj qhov zoo hauv qab no: cov khoom siv coated tsis dhau anodic dissolution, uas txhim kho qhov adhesion thiab corrosion kuj ntawm cov zaj duab xis txheej thiab substrate; Lub hauv paus xim muaj cov pab pawg uas tiv thaiv substrate corrosion (xws li cov pab pawg muaj nitrogen), uas muaj ntau dua corrosion kuj thiab permeability dua anodic electrophoretic coatings, yog li ua rau cov kab noj hniav thiab weld seam ntawm cov txheej txheej zoo dua coated.
