Aluminium yog lub teeb, mos tsis-ferrous hlau, yooj yim oxidized nyob rau hauv cov huab cua, yog li cov neeg tuaj nrog ib txoj kev, uas yog, txhuas oxidation txheej txheem, txheej txheej txheej ntawm kev loj hlob ntawm kev tiv thaiv zaj duab xis, ua kom nws ruaj, thiab yuav dyed. rau hauv cov yeeb yuj xim, pleasing rau lub qhov muag.
Lub hauv paus ntsiab lus ntawm aluminium anodizing yog txheej txheem ntawm kev tsim cov yeeb yaj kiab zoo nkauj thiab tiv thaiv ntawm cov khoom ua los ntawm txhuas thiab nws cov alloys. Cov txheej txheem ntau lawm ntawm alumina zaj duab xis tsim ntawm txhuas yog los ntawm kev ncaj qha tam sim no nyob rau hauv qhov txaus voltage los ntawm ib tug haum sulfuric acid electrolyte, nyob rau hauv uas txhuas yog lub anode, thiab lwm yam khoom (cov hlau lead los yog tshwj xeeb graphite phaj) raws li lub cathode, muaj txhuas profile hluav taws xob rau ib tug. Qee lub sij hawm maj mam loj hlob qhov yuav tsum tau ua thickness ntawm oxide zaj duab xis.
Tom qab cov yeeb yaj kiab raug tsim, ntxiv rau qee cov xim txhuas tsis tas yuav tsum tau kho, cov kauj ruam tom ntej yog ua cov xim kho. Feem ntau hais lus, cov xim ntawm txhuas feem ntau muab faib ua cov hauv qab no:
1. Organic dye
2. Inorganic dyeing
3. Electrolytic xim
4. Electroplating tinting
Ntawm no peb tsuas yog tham txog lub hauv paus ntsiab lus, qhov zoo thiab qhov tsis zoo ntawm cov organic dyeing thiab electrolytic xim, nrog rau cov khoom siv sijhawm:
1. Cov xim xim electrolytic yog ua raws li pob tshab anodic oxide zaj duab xis ntawm sulfuric acid thawj electrolysis. Hauv cov tshuaj uas muaj cov ntsev ntsev, cov xim xim electrolytic (tseem hu ua cov yeeb yaj kiab electrolytic thib ob) muaj cov huab cua zoo dua, lub teeb tsis kam thiab kev pab cuam lub neej tshaj li dyeing zaj duab xis, thiab nws lub zog noj thiab xim xim yog qis dua qhov xim tag nrho. zaj duab xis. Tam sim no, nws yog dav siv los tsim cov txhuas profile xim, tab sis cov xim ntawm cov xim electrolytic yog monotonous, feem ntau tsuas yog tooj liab, dub, kub, jujube liab thiab lwm yam. Thiab kev ua haujlwm tsis yooj yim los tswj.
2. Organic dyeing, organic dyeing raws li adsorption txoj kev xav ntawm cov khoom, adsorption yuav muab faib ua lub cev adsorption thiab tshuaj adsorption, lub cev adsorption ntawm industrial aluminium profiles yog adsorption ntawm molecules los yog ions los ntawm electrostatic quab yuam; Chemorption, adsorption los ntawm chemical rog, uas ua ke los tsim cov organic staining, feem ntau ntawm qhov kub thiab txias. Vim lawv lub siab anodic oxidation zaj duab xis porosity, adsorption muaj peev xwm rau cov organic dyes, txoj kev no xim ceev, ci xim, yooj yim rau kev khiav lag luam, lub qhov sealing kev kho mob tom qab dyeing, cov dye yuav nrees adhere rau daim nyias nyias pores, txhim kho lub anticorrosive muaj peev xwm. zaj duab xis, sib ntaus corrupt peev xwm, kom txog rau thaum muaj peev xwm ua kom zoo nkauj xim, haum rau sab nraum zoov siv rau cov neeg uas tsis xav tau ib tug loj tus naj npawb ntawm cov khoom siv txhuas, Sab hauv nrog txhuas cov khoom lag luam thiab cov khoom kho kom zoo nkauj, cov tsos ntawm ntau yam xim. Ntsib cov neeg niaj hnub niaj hnub tshuaj xyuas thiab nrhiav kev nyiam kev zoo nkauj, txhim kho kev sib tw muaj peev xwm ntawm cov khoom lag luam. Organic dyeing muaj qee cov yam ntxwv thiab kev xav tau rau oxide zaj duab xis:
1. Cov oxide zaj duab xis yuav tsum muaj txaus porosity
2. Sab hauv phab ntsa ntawm lub qhov membrane tuav qee yam haujlwm
3. Cov yeeb yaj kiab anodized tau los ntawm txhuas hauv sulfuric acid tov yog xim tsis muaj xim thiab ntxeem tau, yog li nws yog qhov tsim nyog rau staining.
4. Cov yeeb yaj kiab oxide yuav tsum muaj qee qhov tuab, thiab cov yeeb yaj kiab nyias tsuas tuaj yeem ua xim nrog lub teeb heev.
5. Hard anodic oxide zaj duab xis nrog chromic acid pa oxide zaj duab xis tsis haum rau organic dyeing
6. Cov oxide zaj duab xis yuav tsum ua kom tiav thiab zoo ib yam, tsis muaj khawb, trachoma, qhov chaw corrosion thiab lwm yam tsis xws luag.
7. Cov txheej txheem zaj duab xis nws tus kheej muaj cov xim zoo, thiab tsis muaj qhov sib txawv ntawm cov qauv metallographic, xws li cov nplej loj lossis kev sib cais loj, yog li muaj qee qhov yuav tsum tau ua rau cov khoom siv aluminium alloy, alloy cov khoom ntawm silicon, magnesium, manganese, hlau, tooj liab. , chromium thiab lwm cov ntsiab lus siab dhau lawm, feem ntau ua rau oxide zaj duab xis tsaus matte, thaum xim hloov.
