Raws li peb txhua tus paub, Galvanizing ntawm cov casters yog qhov ua tau ib txheej ntawm zinc nyob rau saum npoo ntawm lub ci ci, feem ntau yog rau kev tiv thaiv thiab xeb tiv thaiv. Txawm li cas los xij, muaj ntau txoj hauv kev rau Galvanizing Casters, thiab ntau txoj kev galvanizing siv nyob rau ntau qhov chaw. Cov log hauv qab no yog qhia ntau txoj hauv kev ntawm Galvanizing Casters.
1. Cyanide Galvanizing
Txij li cyanide (CN) yog muaj kev tiv thaiv zoo, ib puag ncig muaj kev txwv tsis pub siv cov khoom siv Nws yog qhov yuav tsum tau siv cov cyanide tsawg (micro cyanide) cov khoom siv hluav taws xob lub cuab yeej electroplilating kua. Cov khoom lag luam zoo ntawm cov khoom siv tais diav yam khoom siv hluav taws xob tom qab siv cov txheej txheem no yog qhov zoo tau txais kev ua kom zoo tom qab passivation ntawm cov xim plating.
2. Zinc Plating
Cov txheej txheem zinc plating txheej txheem hloov zuj zus ntawm cyanide zinc plating. Tam sim no, muaj ob lub chaw loj hauv Suav teb:
(1) Wuhan Institute ntawm Cov Khoom Tiv Thaiv Cov Khoom Siv "DPE"
(2) xov tooj cua thiab lub koom haum TV "tsib"
Ob qho tib si nrog Zinc Plating nrog alkaline additives; Tus nqi PH yog 12,5 ~ 13. Tus qauv kev ua kom zoo ntawm cov txheej txheej uas siv cov txheej txheem no yog tas, nrog zoo corrosion tsis kam, haum rau xim zinc plating.
Cov Qauv Raug: Nah -} - 110 ~ 120g / u; ZNO - 11 ~ 12G / L; 94--5 ~ 7g / l . 94 yog cov khoom lag luam rau kev sib txuas ntawm "DPE-ⅱ" thiab ethanolamine.
Nco tseg: Tom qab cov khoom tawm ntawm lub tank, ntxuav nrog dej, polish (ua haujlwm nrog dej, ua kom qhuav, qhuav, thiab hnub nyoog (80 ~ 90o fais hauv qhov cub).
3. Chloride Zinc Plating
Cov chloride cov txheej txheem yog siv dav hauv kev lag luam electroplating ntawm cov khoom kho kom zoo, suav nyiaj txog 40%. Tom qab passivation (xiav - mov dawb), tshwj xeeb yog tom qab ntxiv rau kev sib txawv, feem ntau yog zinc plating seb puas yog zinc plating lossis chrome plating. Cov txheej txheem no yog tsim nyog rau cov xim passivation (xiav - dawb, nyiaj- dawb). Thaum cov neeg siv khoom tsis muaj cov cai tshwj xeeb, nws yog qhov zoo rau xaiv cov nyiaj - cov xim tsis muaj zog (cov xim tseem ruaj ntseg).
Cov Qauv Raug: KCl - 180 ~ 220G / L; ZNCL - 65 ~ 75G / L; H3bo3--25 ~ 30g / l (tsis yog); PH tus nqi yog 5 ~ 5.5; Ci-87--15 ~ 20g / l (Brightener).
4. Sulfate zinc plating
Sulfate Zinc plating txheej txheem yog tsim rau kev txuas hniav ntxiv (xaim, sawb, yooj yim, loj thiab cov khoom siv qis.
Cov Qauv Raug: ZSO4--300 ~ 500g / l; H3bo3--25 ~ 30G / l; PH tus nqi: 4.5 ~ 5.5; Zinc Sulphur - 15 ~ 20G / L (Brightener).
