Kub-DIP Galvanizingyog ib txoj kev siv dav dav rau kev tiv thaiv steel thiab hlau los ntawm corrosion. Cov txheej txheem no cuam tshuam nrog cov hlau hauv da dej ntawm Molten Zinc, uas ua ib qho muaj zog, tiv thaiv cov txheej. Lub galvanized hlau tau muaj kev tiv taus xeb thiab tuaj yeem tiv taus cov xwm txheej hnyav. Txawm li cas los xij, kev ua tiav cov txiaj ntsig zoo tshaj plaws xav tau kev ua raws li cov cai thiab kev coj ua zoo tshaj plaws. Tsab ntawv no rho tawm mus rau hauv cov kev xav tau tseem ceeb rau kub-dip galvanizing kom ntseeg tau tias muaj txiaj ntsig zoo thiab ruaj khov.
1. Cov khoom xaiv
Thawj qhov yuav tsum tau rau kub-dip galvanizing yog xaiv cov khoom uas tsim nyog. Tsis yog txhua tus hlau yog haum rau tus txheej txheem no. Feem ntau, cov hlau thiab hlau yog thawj cov neeg sib tw. Cov muaj pes tsawg leeg ntawm cov hlau tuaj yeem cuam tshuam ntau rau qhov zoo ntawm covGalvanizingCov. Piv txwv li, muaj cov ntsiab lus xws li silicon thiab phosphorus hauv cov hlau tuaj yeem cuam tshuam cov tuab thiab muaj zog ntawm zinc txheej. Yog li ntawd, nws yog qhov tseem ceeb rau kev xaiv cov ntaub ntawv nrog kev tswj hwm thiab paub txog kev ua tiav kom ua tiav cov txiaj ntsig sib xws.
2. Nto Npaj
Cov kev npaj saum npoo yog cov kauj ruam tseem ceeb hauvKub-DIP Galvanizingtxheej txheem. Lub hlau nto yuav tsum yog huv thiab tsis muaj paug los ntawm cov khoom tsis huv xws li roj, roj, xeb, thiab zeb nplai. Ib qho impurities twg tuaj yeem tiv thaiv cov zinc los ntawm adhering kom zoo, ua rau tsis zoo txheej zoo. Cov kev npaj nto feem cuam tshuam nrog peb theem:
- Degreasing: Tshem tawm cov organic paug uas siv cov kev daws teeb meem alkaline lossis cov kuab tshuaj.
- Pickling: Tshem tawm ntawm xeb thiab nplai siv cov kua qaub acidics, feem ntau hydrochloric lossis sulfuric acid.
- Fluxing: Daim ntawv thov ntawm flux tov, feem ntau zinc ammonium chloride, kom tiv thaiv oxidation ua ntej kev nkag mus rau hauv Molten zinc.
Kev npaj ua kom zoo ua kom muaj zog sib txuam ntawm cov hlau thiab zinc txheej thiab zinc txheej, txhim kho lub durability thiab zoo ntawm galvanizing.
3. Da dej muaj pes tsawg leeg thiab ntsuas kub
Cov muaj pes tsawg leeg thiab qhov kub ntawm cov dainc tseem ceeb hauv cov txheej txheem kub-dip galvanizing. Cov da dej zinc yuav tsum muaj tsawg kawg 98% ntshiab zinc, nrog cov seem seem zoo li cov khoom siv txhuas, txhuas, thiab cov tshuaj pleev kom zoo nkauj los txhim kho cov txheej txheej. The bath temperature typically ranges between 820°F and 860°F (438°C to 460°C). Tswj qhov ntsuas kub yog qhov tseem ceeb rau kev ua tiav cov khaub ncaws hnav thiab cov khoom zoo. Kev sib txawv tuaj yeem ua rau tsis xws luag xws li tsis sib xws, tsis zoo adhesion, thiab saum npoo roughness.
4. Lub sijhawm tshem tawm
Lub sijhawm siv zog hauv cov da dej zinc yog lwm qhov sib txawv. Nws nyob ntawm cov tuab thiab loj ntawm lubHlau ua GalvanizedCov. Feem ntau, cov hlau yog raus kom txog thaum nws mus txog da dej kub, tso cai rau qhov zinc los ua cov sib txuas sib txuas nrog hlau. Tshaj-immersion tuaj yeem ua rau muaj kev sib tw tuab heev, thaum lub sij hawm hauv qab-immersion tuaj yeem ua rau muaj kev tiv thaiv tsis txaus. Yog li ntawd, kho kom haum ntawm lub sijhawm raus hluav taws xob yog tsim nyog kom ua tiav cov kev xav tau tuab thiab zoo.
5. Post-Galvanizing Kho
Tom qab cov hlau raug tshem tawm ntawm lubDinc Da Dej, nws undergoes ncej-galvanizing kev kho kom txhim kho cov txheej txheej cov khoom. Cov kev kho mob no yuav suav nrog quenching hauv dej lossis huab cua txias kom muaj cov txheej txheej zinc sai sai. Ib qho ntxiv, kev kho mob hla dhau tuaj yeem siv tau los tiv thaiv kom tiv thaiv kev tsim ntawm cov xeb dawb, ib hom corrosion uas tuaj yeem tshwm sim ntawm cov chaw freshly. Tsim kom zoo thiab cia ntawm Galvanized cov ntaub ntawv kuj tseem ceeb rau kev tswj hwm cov txheej sib luag.
6. Kev tshuaj xyuas thiab kev tswj hwm zoo
Thaum kawg, kev tshuaj xyuas kom huv si thiab kev tswj hwm zoo yog qhov tseem ceeb los xyuas kom meej qhov ua tiav ntawmKub-DIP Galvanizingtxheej txheem. Kev kuaj xyuas feem ntau yog kev ntsuas pom, ntsuas tuab, thiab kev ntsuam xyuas cov nplaum. Cov qauv xws li ASTM ATM AV123 / A123M muab cov lus qhia rau kev siv cov tuab thiab zoo. Ua raws li cov qauv no kom ntseeg tau tias cov khoom lag luam Galvanized ua tiav cov qauv tsim nyog thiab muab kev tiv thaiv ntev-ntev tiv thaiv kev xeb.

Kub-DIP galvanizing yog ib txoj hauv kev zoo rau kev tiv thaiv steel thiab hlau los ntawm kev saib xyuas kom meej thiab ua raws li cov cai. Los ntawm cov khoom xaiv thiab kev npaj nto kom da dej ua ke, lub sijhawm siv zog, txhua kauj ruam ua si lub zog tseem ceeb hauv kev ua tiav cov txiaj ntsig zoo thiab ruaj khov. Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws thiab tswj hwm kev tswj hwm nruj heev, cov chaw tsim khoom tuaj yeem xyuas tau tias lawv cov khoom lag luam galvanized xa tawm kev ua tau zoo thiab thiav.
