1. Siv cov txheej txheem pretreatment los ntxuav qhov chaw, uas tuaj yeem tau txais los ntawm kev siv lub cev thiab tshuaj. Qhov tseem ceeb tshaj plaws yog qhov nthuav tawm matrix ntawm aluminium phaj. Nws yog kiag li oxidized thiab oxide zaj duab xis yog ntom. Qee cov cuab yeej siv tshuab ua haujlwm kuj tuaj yeem siv rau kev kho ua ntej.
2. Tom qab anodizing, aluminium coil yog ua tiav los anodize substrate thiab tom qab ntawd tsim cov oxide zaj duab xis tuab.
3. Tom qab sealing thiab anodizing, yuav muaj ntau cov membrane pores nyob rau hauv oxidized zaj duab xis. Lub membrane pores nyob rau hauv lub sealing membrane yog kaw kom tsis txhob muaj kab mob. Cov yeeb yaj kiab no yog pob tshab, thiab nws kuj muaj adsorption, yog li nws yuav muab tso rau hauv qhov hws ntawm qee cov ntsev ntsev, kom nws tuaj yeem pom qee cov xim dawb dawb hauv qhov tsos, lossis ntau yam xim. Qhov no yog xim ntawm aluminium coil thaum ua. Peb yuav tsum tau them sai sai rau cov kev hloov pauv ntawm aluminium coil.
Aluminium coil yuav tsum yog ib txwm vim tias txhuas coil yog oxidized los ua ib tug tuab zaj duab xis oxide zaj duab xis thiab tiv thaiv aluminium los ntawm reacting nrog txhuas.
Txawm li cas los xij, rau txhuas coils nrog cov kev xav tau ntau dua saum npoo, yuav ua li cas kom tsis txhob muaj cov pob dawb ntawm lub ntsej muag ntawm aluminium coil thiab ua kom lub ntsej muag ua kom zoo dua tsis yog tsuas yog cuam tshuam nrog kev ua cov thev naus laus zis, tab sis kuj tseem cuam tshuam nrog cov txheej txheem tom ntej.
Thaum ua anodizing ntawm cov khoom loj aluminium coil, cov pob dawb yuav tshwm rau saum npoo tom qab ua tiav, tshwj xeeb tshaj yog rau txhuas oxide coils. Tam sim no cia peb txheeb xyuas cov laj thawj rau qhov tshwm sim no.
Qhov tseeb, qhov laj thawj tseem ceeb yog qhov yooj yim heev: tom qab aluminium phaj yog oxidized, nws tsis yog rinsed kom huv si, ua rau cov pob dawb ua rau saum npoo tom qab ziab. Tom qab cov tshuaj oxidized thiab ntxuav, yaug nws kom huv si nrog dej huv. Nyob rau tib lub sijhawm, tiv thaiv qhov chaw tom qab ntxuav, sim ua kom cov khoom sib cuag nrog lwm cov khoom, thiab cia nws qhuav lawm.
Txhawm rau tswj cov teeb meem saum npoo ntawm aluminium coils, peb yuav tsum tsis tsuas yog them sai sai rau cov teeb meem saum npoo ntawm cov khoom thaum lub sij hawm ua khoom, tab sis kuj xyuam xim rau kev tiv thaiv nto, nruj txheej txheem txheej txheem thev naus laus zis, thiab zam kev tsim cov pob dawb thaum ua. Kev ntxuav dawb thiab pickling yog ua tau, tab sis txhawm rau tswj cov concentration, nws tseem raug pleev xim rau, thiab aluminium barrier yog nyob rau hauv kev sib cuag nrog oxygen.
