Yog vim li cas thiab kev daws teeb meem rau yellowing ntawm electrophoresis elevator

Yog vim li cas rau yellowing ntawm electrophoretic elevator yog sau tseg raws li nram no: electrophoretic xim nws tus kheej; tsis zoo oxidation conductivity; ntxuav tsis tiav ua ntej electrophoresis; kev kho ntau dhau; oxidation tank kua yog polluted los ntawm nitric acid:

1. Yellowing tshwm sim los ntawm cov hluav taws xob tsis zoo ntawm lub elevator thaum oxidation

Kev sib cuag tsis zoo ntawm lub elevator thiab tus pas ntsuas hluav taws xob yuav ua rau muaj kev tiv thaiv zoo ntawm qhov chaw sib cuag, qhov kawg ntawm qhov profile yuav sov, oxide zaj duab xis yuav raug tsim sai heev thiab nrog rau kev kub hnyiab, thiab txawm tias cov oxide zaj duab xis yuav raug hmoov. Lub sijhawm no, oxide zaj duab xis yog me ntsis turbid, thiab xim tig daj. Yog hais tias electrophoresis tau ua dua, yuav muaj qhov pom tseeb yellowing tshwm sim. Qhov zoo ntawm yellowing tshwm sim feem ntau tsuas yog ob peb ua ke, thiab qhov pib nws tshwm nyob rau qhov kawg ntawm qhov profile. Yog li ntawd, kev ntsuas yuav tsum tau ua kom muaj kev sib cuag zoo ntawm aluminium profile thiab cov pas nrig conductive.

2. Yellowing tshwm sim los ntawm kev ntxuav tsis tiav ua ntej electrophoresis

Cov oxide zaj duab xis yog honeycomb, thiab nws cov qauv ntxeem tau txiav txim siab tias sulfuric acid yuav nyob twj ywm hauv qhov pores ntawm oxide zaj duab xis. Raws li peb txhua tus paub, yog tias cov ntaub ntawv siv rau electrophoresis tsis ntxuav kom huv si, yellowing yuav tshwm sim. Rau qhov tshwm sim daj, nws feem ntau ntseeg tau tias cov kua qaub radicals nyob rau hauv lub qhov hws ntawm oxide zaj duab xis hnov ​​​​mob nrog cov xim electrophoretic ua rau yellowing ntawm electrophoretic xim zaj duab xis. Qhov tseeb, qhov yellowing tsis yog yellowing ntawm cov xim zaj duab xis, tab sis yellowing ntawm oxide zaj duab xis. Hloov. Lub cev oxide zaj duab xis yog qhov tseeb thiab pob tshab. Yog tias ntau sulfate radicals tseem nyob hauv qhov pores ntawm oxide zaj duab xis, oxide zaj duab xis yuav hnov ​​​​mob nrog sulfate radicals nyob rau hauv qhov kub thiab txias, yog li ua kom pom tseeb thiab pob tshab oxide zaj duab xis turbid thiab pob tshab. Nyob rau tib lub sij hawm, ua ke nrog lub siab transparency ntawm cov xim electrophoretic thiab lub siab reflectivity rau lub teeb, qhov no tsis xws luag yog ntxiv amplified, tsim lub thiaj li hu ua yellowing. Yog li ntawd, ntau qhov kev ntxhua khaub ncaws ua ntej electrophoresis yog qhov tseem ceeb heev, tsis yog tsuas yog ua kom cov dej zoo ntawm kev ntxuav, tab sis kuj yuav xyuas kom meej qhov kub thiab txias ntawm lub sijhawm ntxuav.

3. Yellowing tshwm sim tshwm sim los ntawm kev sib kis ntawm nitric acid nyob rau hauv oxidation da dej

Txhawm rau kom ua tiav cov txiaj ntsig zoo dua tshem tawm cov tshauv, nws nkag siab tias yuav ntxiv qee qhov kev faib ua feem ntawm nitric acid nyob rau hauv lub tank neutralization, tab sis yog tias cov dej ntxuav dej tom qab kev tswj tsis tau zoo, cov nitric acid yuav raug coj mus rau lub tank oxidation, thiab nitrate nyob rau hauv lub tank oxidation yuav ncav cuag ib tug tej yam concentration. Nws yuav muaj qee yam cuam tshuam rau oxidation, thiab txawm ua rau yellowing ntawm electrophoretic profiles. Thaum lub sij hawm oxidation txheej txheem, cov nitrates nkag mus rau hauv lub pores ntawm oxide zaj duab xis yuav etch oxide zaj duab xis, corrode lub barrier txheej ntawm oxide zaj duab xis, ua rau cov oxide zaj duab xis pores ntxaum, thiab ces hloov cov qauv ntawm cov zaj duab xis pores. Qhov kev xeb no muaj ob qhov cuam tshuam rau cov yeeb yaj kiab oxide: 1. Cov txheej txheem txheej txheej ntawm oxide zaj duab xis ua thinner, thiab qhov nruj ntawm kev sib txuas nrog aluminium substrate ua phem dua, uas ua rau txo qhov adhesion ntawm oxide zaj duab xis. 2. Nyob rau hauv ib txwm dej ntxuav, nws yog ib qho nyuaj rau tshem tawm cov sulfate radicals nyob rau hauv daim nyias nyias pores. Cov electrophoretic profiles tsim nyob rau hauv xws li tej yam kev mob kuj muaj yellowing phenomenon. Yuav ua li cas kom tsis txhob yellowing tshwm sim? Ntxiv cov tshuaj nruab nrab rau lub tank dej ntshiab ua ntej lub tank scalding, kho tus nqi pH mus rau 8 ~ 9.5, ntxuav nrog dej rau 2 ~ 3 feeb, tshem tawm cov sulfate pawg hauv qhov pores ntawm oxide zaj duab xis nrog amine, thiab tom qab ntawd nqa tawm electrophoresis ntau lawm. , yuav tsis muaj yellowing. phenomenon tau hloov.

4. Yellowing tshwm sim los ntawm kev kho ntau dhau

Tam sim no, cov xim electrophoretic siv nyob rau hauv kev ua lag luam yog pib ci thiab kho nyob rau hauv cov xwm txheej ntawm 180 degree X30min. Nyob rau hauv tej yam kev mob, cov xim zaj duab xis yeej tsis daj. Txawm li cas los xij, qhov kub ntawm qhov cub tua hluav taws kub ntawm qee cov tuam txhab lag luam tsis sib xws, thiab qhov kub hauv zos txawm txawv los ntawm ntau dua 30 degree; Kev tswj qhov kub thiab txias ntawm qhov cub hluav taws xob ntawm qee cov tuam txhab lag luam tsis zoo, qhov tseeb qhov kub thiab txias yog qhov txawv ntawm qhov pom, thiab cov xim electrophoretic ntawm cov khoom tsis zoo yog nyob rau hauv cov xwm txheej zoo li no. Qhov tshwm sim yellowing yog pom tseeb heev, txawm tias zoo li xim. Cov xim zoo nkauj electrophoretic muaj peev xwm tiv taus cov xwm txheej hnyav, thiab qee cov xim electrophoretic yuav tsis tig daj txawm tias lawv ci ntawm 230 degree. Txhawm rau tiv thaiv qhov tshwm sim ntawm yellowing, lub uniformity ntawm lub cub tawg kub thiab rhiab heev ntawm qhov kub thiab txias tswj system yog tsim nyog, thiab nws tseem yuav tsum tau siv ib tug zoo zoo electrophoretic xim.

5. Yellowing tshwm sim los ntawm electrophoretic xim nws tus kheej

Anodized electrophoretic xim yog tsim los ntawm acrylic resin thiab amine-based resin. Thaum lub sij hawm ci txheej txheem ntawm electrophoretic profile, cov resin undergoes ib tug cross-linking cov tshuaj tiv thaiv los tsim ib tug du thiab pob tshab txheej zaj duab xis. Txawm li cas los xij, qee cov tuam txhab pleev xim electrophoretic muaj qhov nqaim kho ntau yam vim yog cov txheej txheem tsim khoom tsis paub tab lossis siv cov khoom siv tsis zoo los txo cov nqi. Yog tias qhov ci tsis txaus, lub hardness ntawm cov xim zaj duab xis tsis txaus; yog tias qhov ci ntau dhau, cov xim zaj duab xis yuav tig daj, uas yuav ua rau muaj teeb meem rau kev tswj ntau lawm. Yog li ntawd, nws raug nquahu kom koj xaiv cov khoom siv xim nrog cov khoom ruaj khov thiab muaj lub koob npe nrov.
