Galvanized xeb-pov thawj aluminium yog qhov tseem ceeb heev. Thaum lub sijhawm txheej txheem no, zinc tuaj yeem tshwm sim, uas yuav cuam tshuam rau kev ua haujlwm ntawm xeb-pov thawj aluminium thiab ua rau pov tseg. Yog li ntawd, peb yuav tsum tau ntsuas kom tsis txhob muaj qhov tshwm sim no tshwm sim.
Ntxiv dag zog rau pretreatment ntawm kub dip galvanizing
2. Txo lub sijhawm nyob ntawm tus txheej txheem kom ntau li ntau tau
3. Xyuas kom cov huab hwm coj concentration thiab tsim nyog feem ntawm electroplating additives
4. Tiv thaiv kom tsis txhob kub dhau thiab kub hnyiab ntawm tus neeg sawv cev plating
5. Cov ntsiab lus txhuas hauv cov kua zinc yog tswj hauv qab no 0.05%. Nws raug pom zoo kom siv 5-10% aluminium master alloy es tsis txhob siv cov ntshiab txhuas ingots ncaj qha.
6. Khaws qhov saum npoo ntawm zinc da dej kom huv si kom tsis txhob muaj cov ntsiab lus ntawm aluminium ntawm qhov nkag ntawm lub workpiece.
7. Tsis txhob khaws cov pa roj carbon ntau
8. Ua tib zoo tshem cov welding slag thiab spatter
Tom qab tshem tawm cov residual frosting, tshem tawm cov nplaim txiav nto
10. Cov kuab tshuaj muaj zog siab tuaj yeem ua ntej-plated nyob rau hauv qhov chaw uas galvanization yog feem ntau to
Kub-dip galvanizing ntawm anti-xeb txhuas daim hlau yog ib txoj kev ntawm hlau los tiv thaiv corrosion.
Kub-dip galvanizing yog txhawm rau txhawm rau xeb tshem tawm cov hlau hauv cov kua zinc molten ntawm li 500 degree, kom cov zinc txheej txuas rau saum npoo ntawm cov hlau, yog li ua tiav lub hom phiaj ntawm kev tiv thaiv corrosion. Kub-dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev.
Cov txheej txheem kub-dip galvanizing ntws yog: pickling ntawm cov khoom tiav - dej ntxuav - ntxiv plating tov - ziab - khib plating - txias - tshuaj kho mob - tu - polishing - kub-dip galvanizing tiav.
