Product Description
Electro-coating ntawm aluminium profiles yog txheej txheej uas siv cov hluav taws xob sab nraud los ua cov khoom xws li pigments thiab resins tshem tawm hauv cov tshuaj electrophoretic directionally migrate thiab tso rau ntawm lub substrate nto ntawm ib qho ntawm cov electrodes.
Electrophoretic txheej yog muab cov khoom ua haujlwm thiab cov khoom siv hluav taws xob sib txuas rau hauv cov dej-soluble txheej, thiab tom qab txuas lub zog hluav taws xob, tso siab rau lub cev thiab tshuaj lom neeg ua haujlwm tsim los ntawm hluav taws xob teb los ua cov resin, pigment thiab muab tub lim rau hauv cov txheej txheem txheej. qhov saum npoo ntawm electrode nrog txheej txheej raws li cov electrode.Ib txheej txheej uas nag lossis daus ua rau cov xim tsis muaj dej-insoluble zaj duab xis.Electrophoretic txheej yog txheej txheem electrochemical ntau heev, suav nrog tsawg kawg plaub txheej txheem ntawm electrophoresis, electrodeposition, electroosmosis thiab electrolysis.Electrophoresis txheej tuaj yeem muab faib ua anodic electrophoresis (lub workpiece yog anode, thiab txheej yog anionic) thiab cathodic electrophoresis (lub workpiece yog cathode, thiab txheej yog cationic) raws li qhov kev ua tau zoo deposition;Raws li cov khoom siv hluav taws xob, nws tuaj yeem muab faib ua DC electrophoresis thiab AC electrophoresis;Muaj qhov tsis tu ncua voltage thiab tsis tu ncua tam sim no txoj kev.Tam sim no, anode electrophoresis ntawm DC fais fab tuag voltage txoj kev yog dav siv nyob rau hauv kev lag luam.
Cov txheej txheem ntws yog
Pre-tu → online → degreasing → dej ntxuav → xeb tshem tawm → dej ntxuav → neutralization → dej ntxuav → phosphating → dej ntxuav → passivation → electrophoresis txheej → tank tu → ultrafiltration dej ntxuav → ziab → offline.
