Taw qhia
Hauv kev lag luam niaj hnub, Nto Kho Tshuab yog qhov tseem ceeb hauv kev txhim kho cov khoom pom zoo, Corrosion Kuj, thiab kev pabcuam lub neej. Electrophoretic txheej thiab hmoov txheej yog ob pawg siv dav dav dav, Txhua tus nrog cov txiaj ntsig zoo thiab cov ntawv thov. Kab lus no yuav tshawb txog cov sib txawv ntawm electrophoresis thiab hmoov txheej, suav nrog cov ntsiab cai ua haujlwm, cov txheej txheem, Qhov zoo thiab qhov tsis zoo, thiab thaj chaw thov, Txhawm rau pab cov nyeem nyeem tau zoo dua cov yam ntxwv thiab cov xwm txheej haum ntawm ob lub thev naus laus zis.
1. Electrophoretic Txheej Tshuab
1.1 Ua Haujlwm Cov Ntsiab Cai
Hluav Taws Xob Txheej (Electrophoretic Dankition, Phaum mob) Puas yog txheej txheej thev naus laus zis uas siv hluav taws xob teb kom tso nyiaj rau cov khoom sib tw mus rau saum npoo ntawm ib qho chaw ua haujlwm. Tus txheej txheem yooj yim yog tias nyob rau hauv kev nqis tes ua ntawm ib daim teb hluav taws xob, them coating hais (feem ntau cob thiab pigments) txav mus rau qhov kev them hluav taws xob (workpiece) thiab tsim cov txheej txheem sib dhos ntawm cov chaw ua haujlwm. Electrophoretic txheej yog feem ntau muab faib ua ob hom: Anodic Electrophoresis thiab Cathodic Electrophoresis.
Anodic Electrophorises: Lub workpiece pabcuam ua anode, thiab cov txheej txheej yog qhov tsis zoo them, Tsiv mus rau lub workpiece thiab kev tso nyiaj.
Cathodic Electrophoresis: Lub workpiece ua haujlwm raws li cathode, thiab cov txheej txheej yog qhov them tau zoo, Tsiv mus rau lub workpiece thiab kev tso nyiaj.
1.2 Txheej Txheem Flow
Cov txheej txheem ntws ntawm Electrophoretic Txheej feem ntau yog suav nrog cov kauj ruam hauv qab no:
- Pretricatment: Nrog rau cov degreasing, derusting, thiab phosphating kom ntseeg tau qhov chaw ua haujlwm yog huv thiab muaj cov nplaum zoo.
- Hluav Taws Xob Txheej: Lub workpiece yog raus hauv lub tshuab hluav taws xob, Thiab cov txheej txuas ntxiv tso nyiaj rau ntawm cov chaw ua haujlwm hauv qab hluav taws.
- Tso yaug: Tshem tawm undeposited muab cov lus los ntawm cov workpiece nto.
- Kev kho: Cov txheej txheej yog ua kom khov kho los ntawm cov cua sov kom tsim zaj duab xis ruaj khov.
1.3 Qhov Zoo
Kev sib koom: Electrophoretic txheej tuaj yeem ua tiav cov txheej txheej sib txawv heev, Txawm hais tias ua haujlwm nrog cov duab nyuaj.
Muaj zog adhesion: Txij li ntawm cov txheej tso tawm ncaj qha rau hauv qhov chaw ua haujlwm hauv qab hluav taws, Kev sib raug zoo ntawm cov txheej thiab lub substrate yog muaj zog.
Ib puag ncig ua phooj ywg: Electrophoretic txheej siv cov txheej txheej ua haujlwm siab nrog cov khib nyiab tsawg, thiab feem ntau yog cov dej-raws li, ua nws ib puag ncig tus phooj ywg.
Kev siv tshuab: Electrophoretic txheej yog yooj yim siv, ua rau nws haum rau kev tsim khoom loj.
1.4 Tsis zoo
Cov khoom siv siab: Electrophoretic txheej khoom siv tau yooj yim thiab yuav tsum muaj qhov kev nqis peev tseem ceeb.
Tsawg Txheej Txheej Thickness: Txheej txheej tuab hauv Electrophoretic txheej feem ntau yog cov nyias nyias, ua rau nws nyuaj ua kom tiav cov txheej txheej tuab tuab.
Muaj kev xaiv xim tsawg: Electrophoretic txheej muaj ob peb cov xim xaiv, feem ntau txwv rau tib xim.
1.5 Chaw thov
Electrophoretic txheej yog dav siv nyob rau hauv kev lag luam xws li Automotive, Khoom Siv Hauv Tsev, thiab kho vajtse, tshwj xeeb hauv cov ntawv thov uas yuav tsum tau ua rau muaj kev tiv thaiv kev ua haujlwm siab thiab hnav tsoos tsho loj, xws li lub tsheb lub cev, CHASSIS, Tsev nyob.
