Kev cai hmoov coated aluminium ntawv hlau machined stampings

Txheej txheem khiav

Cov txheej txheem hmoov txheej rau cov khoom siv txhuas yog cov txheej txheem kho saum npoo uas tsim cov txheej txheem tiv thaiv ntawm cov ntaub ntawv txhuas. Nws yog tsuas yog siv los txhim kho corrosion kuj, zoo nkauj thiab durability ntawm txhuas cov khoom. Cov hauv qab no yog kev taw qhia rau peb cov txheej txheem hmoov txheej:

1. Npaj cov aluminium alloy substrate: Ua ntej, aluminium alloy substrate yuav tsum tau muab ntxuav kom tshem tawm cov roj stains, oxide txheej thiab lwm yam impurities ntawm qhov chaw kom ntseeg tau tias cov hmoov txheej tuaj yeem ua raws li cov txheej txheem zoo. Cov txheej txheem ntxuav yuav suav nrog degreasing, ntxuav dej, ntxuav alkali, pickling thiab lwm cov kauj ruam kom ua tiav kev tu huv.
2. Npaj cov hmoov txheej: Xaiv cov hmoov txheej uas tsim nyog raws li cov xim xav tau, kev ua tau zoo thiab cov txheej tuab. Hmoov txheej feem ntau muaj xws li pigments, resins, fillers, additives thiab lwm yam khoom xyaw. Lawv tau npaj los ntawm cov txheej txheem tshwj xeeb thiab muaj adhesion zoo thiab huab cua tsis kam.
3. Electrostatic txau: Txau cov hmoov txheej rau ntawm aluminium alloy substrate los ntawm cov khoom siv electrostatic txau. Nyob rau hauv qhov kev txiav txim ntawm hluav taws xob zoo li qub, cov hmoov txheej yuav sib npaug adsorbed rau ntawm qhov chaw ntawm lub substrate los ua ib txheej txheej. Electrostatic txau muaj qhov zoo ntawm kev ua haujlwm siab, kev tiv thaiv ib puag ncig, thiab txheej txheej tsis sib xws.
4. Kev kho: Muab cov khoom siv tshuaj txau rau hauv qhov cub kub kom yaj, theem thiab solidify cov hmoov txheej ntawm qhov kub thiab txias. Thaum lub sij hawm kho, cov resin nyob rau hauv cov hmoov txheej reacts chemically tsim ib tug muaj zog txheej uas bonds nruj nreem rau lub substrate. Curing kub thiab lub sij hawm yuav tsum tau kho raws li hom thiab thickness ntawm cov hmoov txheej los xyuas kom meej qhov zoo ntawm cov txheej.
5. Kev ua kom txias thiab ua haujlwm tom qab: Tom qab cov khoom tau txias rau chav sov hauv qhov cub, tshem tawm thiab ua cov txheej txheem tom ntej. Qhov no suav nrog cov kauj ruam xws li xuab zeb thiab polishing los txhim kho qhov gloss thiab smoothness ntawm txheej.

Hauv cov txheej txheem hmoov txheej, koj kuj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:

Ua kom lub ntsej muag huv thiab flatness ntawm aluminium alloy substrate los txhim kho qhov adhesion thiab zoo nkauj ntawm txheej.
Xaiv cov hmoov txheej tsim nyog thiab cov khoom siv tshuaj tsuag kom ntseeg tau tias qhov zoo thiab ruaj khov ntawm txheej.
Tswj qhov kub thiab lub sijhawm ntawm cov txheej txheem kho kom tsis txhob muaj qhov tsis xws luag xws li blistering thiab tawg hauv txheej.
Ua tib zoo saib xyuas kev nyab xeeb thiab kev tiv thaiv ib puag ncig thaum lub sijhawm ua haujlwm kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab txo cov pa phem ib puag ncig.

Cov txheej txheem hmoov txheej rau cov khoom siv txhuas yog ib qho tseem ceeb ntawm kev kho tshuab. Los ntawm cov txheej txheem tsim nyog thiab kev tswj xyuas kev ua haujlwm, txheej txheej nrog kev ua tau zoo thiab kev zoo nkauj tuaj yeem tau txais, txhim kho kev siv tus nqi thiab kev lag luam kev sib tw ntawm cov khoom siv txhuas.
