Nws pib qhov chaw electrophoretic painting kab EDP KTL

Cov txheej txheem electrophoretic txheej, zoo dua lub npe hu ua E-coat, muaj cov immersion ntawm qhov chaw nyob rau hauv ib tug dej-raws li tshuaj uas muaj ib tug xim emulsion. Thaum cov khoom tau muab tso rau hauv dej, siv hluav taws xob tam sim no, qhov no ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau cov xim pleev xim rau saum npoo. Ib txheej txheej yog tsim nyob rau hauv daim, vim hais tias cov seem yuav tsum tau pleev xim nyob rau hauv ib tug cais, uas tiv thaiv lawv los ntawm ib tug ntau dua thickness ntawm cov xim.

Kev siv dav dav hauv kev tsim vaj tsev dav siv los siv primer lossis tiv thaiv txheej, electrophoretic txheej, electropainting, electrodeposition, electrophoretic deposition (EPD), los yog e-txheej, yog tag nrho cov npe rau ib tug txheej txheem uas siv ib tug nyias, ruaj, thiab corrosion-resistant epoxy. resin txheej rau hlau Cheebtsam.

Muaj ntau cov txiaj ntsig rau electrocoating, nrog rau cov nqi ua tau zoo, kab tsim khoom thiab ib puag ncig zoo. Tus nqi ua tau zoo hauv electrocoat yog kev hloov pauv ntau dua, kev tswj cov yeeb yaj kiab-tsim, thiab cov neeg ua haujlwm tsawg. Cov kab ntau lawm hauv electrocoat yog vim txoj kab nrawm dua, ntom ntom ntom ntawm cov khoom, cov kab tsis sib xws, thiab txo tib neeg qaug zog lossis yuam kev.

Qhov zoo ntawm ib puag ncig yog tsis muaj- lossis qis-VOC thiab HAPs cov khoom lag luam, cov khoom tsis muaj hlau hnyav, txo cov neeg ua haujlwm raug mob rau cov khoom siv phom sij, txo qhov phom sij hluav taws, thiab pov tseg yam tsawg kawg nkaus.

Ntxuav qhov chaw
Roj, qias neeg thiab lwm yam khoom seem uas tuaj yeem tiv thaiv qhov adhesion ntawm e-coat. Yog li ntawd, qhov saum npoo yuav tsum tau ntxuav kom zoo ua ntej yuav mus ntxiv. Hom tshuaj ntxuav siv yuav txawv raws li hom hlau. Rau cov hlau thiab hlau, cov tshuaj inorganic phosphate feem ntau yog nyiam. Rau cov nyiaj thiab kub, cov tshuaj ntxuav alkaline muaj ntau heev.
Lub tshuab nqus tsev ultrasonic yog lub cuab yeej zoo tshaj plaws rau txoj haujlwm no. Lub tank no siv cov tshuab vibrations los tsim cov suab nrov hauv dej los yog tshuaj ntxuav. Thaum cov khoom siv hlau muab tso rau hauv cov tshuaj, cov npuas tsim los ntawm cov suab nrov yuav ntxuav txawm tias cov chaw nyuaj mus txog.

Yaug
Thaum cov khoom tsis muaj tag nrho cov av thiab khawb, nws yuav tsum tau yaug hauv dej distilled thiab neutralizer. Qhov no yuav pab tshem tawm cov seem uas tshwm sim los ntawm cov tshuaj siv hauv cov txheej txheem ntxuav. Cov kauj ruam no yuav tsum tau rov ua dua ob peb zaug kom ntseeg tau tias cov khoom tsis muaj kev puas tsuaj. Ua li ntawd, koj yuav muaj txoj hauv kev zoo dua rau kev ua tiav adhesion thaum lub sij hawm e-txheej txheej txheem.

Tus neeg sawv cev ntub dej
Qee cov tuam txhab E-coat xav kom tus neeg sawv cev ntub dej hauv lub tank tam sim ua ntej E-coat tank. Qhov no feem ntau yog los tiv thaiv npuas los ntawm adhering rau qhov chaw thaum lawv mus rau hauv lub e-coat tank. Txhua npuas txuas rau ntawm qhov chaw yuav tiv thaiv E-coat deposition thiab yuav ua rau cov xim tsis xws luag hauv qhov tiav.

E-txheej txheej
Thaum koj paub tseeb tias cov khoom tau raug ntxuav kom huv si, nws yog lub sijhawm los muab nws tso rau hauv cov tshuaj e-txheej txheem. Cov tshuaj siv nyob rau hauv cov tshuaj yuav nyob ntawm ob peb yam, xws li hom hlau uas cov khoom yog ua los ntawm.
Xyuas kom meej tias tag nrho cov khoom yog submerged. Qhov no yuav ua kom muaj txheej txheej ntawm txhua nti ntawm cov khoom, suav nrog cov crevices uas nyuaj rau ncav cuag. Cov hluav taws xob tam sim no khiav los ntawm kev daws teeb meem yuav ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv uas fuses txheej rau cov hlau nto.

Kho cov txheej
Thaum cov khoom raug tshem tawm los ntawm cov tshuaj e-txheej txheem, nws tau ci hauv qhov cub. Qhov no ua rau lub hardening txheej los xyuas kom meej durability, thiab kuj tsim ib tug glossy tiav. Qhov kub ntawm qhov khoom yuav tsum tau kho yuav nyob ntawm seb cov chemistry ntawm cov tshuaj e-txheej txheem uas tau siv.
