Lub hauv paus ntsiab lus ntawm electrogalvanizing yog dab tsi?
Electrolysis yog siv los tso zinc ions los ntawm cov tshuaj plating mus rau cov hlau substrate, tsim ib txheej zinc txheej rau kev tiv thaiv corrosion.
Dab tsi yog cov txheej txheem siv electrogalvanizing?
Acidic zinc plating (xws li sulfate zinc plating): ceev ceev deposition tus nqi, haum rau tej yam yooj yim.
Alkaline zinc plating (xws li cyanide thiab cyanide-dawb alkaline zinc plating): Ua ib txheej txheej, tsim nyog rau qhov nyuaj.
Chloride zinc plating: Sib npaug ceev thiab sib xws, ua rau nws siv dav.
Dab tsi yog cov kauj ruam tseem ceeb hauv substrate pretreatment?
Degreasing (tshuaj lom neeg / electrochemical), xeb tshem tawm (pickling), thiab ua kom (tsis muaj zog pickling) yuav tsum tau ua kom lub substrate tsis muaj roj thiab nplai, uas yuav txwv tsis pub lub adhesion ntawm txheej.
Dab tsi yog cov khoom tseem ceeb thiab kev ua haujlwm ntawm cov tshuaj plating?
Cov ntsev tseem ceeb (xws li zinc chloride thiab zinc sulfate): Muab zinc ions, ua lub hauv paus ntawm txheej txheej.
Cluling agents (xws li cyanide thiab nitrilotriacetic acid): Stabilize zinc ions thiab tiv thaiv nag lossis daus. Additives (brighteners, sizing agents): Txhim kho lub ci ci thiab uniformity ntawm txheej.
Qhov ntom ntom tam sim no cuam tshuam li cas rau txheej?
Tsawg dhau qhov ceev tam sim no ua rau cov txheej nyias nyias thiab tsis sib xws; siab heev tam sim no ceev tuaj yeem ua rau "hlawv" (ntxhiab, blackened txheej). Qhov zoo tshaj plaws yuav tsum tau kho raws li tus txheej txheem.
