Kub-dip galvanizing yog dab tsi?

Kub-dip galvanizing yog ib qho txheej txheem ntawm kev npog cov hlau saum npoo nrog zinc txheej, lub hom phiaj tseem ceeb ntawm cov khoom yogtiv thaiv hlau oxidation thiab corrosion.

Kub-dip galvanizing yog muab tso rau hauv cov hlau ua haujlwm hauv molten zinc kua los tsim cov txheej txheem tiv thaiv. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

Kev kho mob:
Degreasing: Tshem tawm cov impurities xws li roj, plua plav, thiab lwm yam ntawm cov hlau nto, feem ntau yog siv cov tshuaj alkaline los ntxuav.
Pickling: Siv dilute hydrochloric acid los yog sulfuric acid kom tshem tawm oxide nplai thiab xeb ntawm cov hlau nto kom huv si.
Kev ntxuav dej: Tshem tawm cov kua qaub uas tseem tshuav thaum lub sij hawm pickling kom tsis txhob cuam tshuam cov txheej txheem tom ntej.
Plating pab kho: Raus lub workpiece nyob rau hauv ib tug plating pab (xws li zinc chloride tov) los tsim ib tug nyias txheej los tiv thaiv cov hlau nto los ntawm oxidizing dua ua ntej galvanizing thiab txhim kho cov adhesion ntawm zinc.

Kub-dip galvanizing:
Raus lub pretreated workpiece nyob rau hauv ib tug molten zinc tov ntawm txog 450 ° C kom hnov ​​zinc nrog cov hlau matrix los ua ib tug zinc-hlau alloy txheej thiab ib tug ntshiab zinc txheej.

Txias:
Nqa cov khoom ua haujlwm tawm ntawm cov kua zinc, thiab txias nws nrog huab cua lossis dej kom cov zinc txheej khov sai sai thiab tsim cov txheej txheem tiv thaiv.

Kev kho mob tom qab:
Qee zaum kev kho mob passivation yuav tsum tau tiv thaiv kom tsis txhob xeb dawb ntawm qhov chaw ntawm txheej galvanized.
Ua kom tiav qhov chaw ntawm lub workpiece, xws li tshem tawm cov zinc nodules, burrs, thiab lwm yam.

Kev soj ntsuam zoo:
Tshawb xyuas cov thickness, adhesion, tsos, thiab lwm yam ntawm txheej galvanized kom paub tseeb tias cov galvanizing zoo ntawm lub workpiece ua tau raws li tus qauv.

Cov yam ntxwv ntawm kub-dip galvanizing: zinc txheej yog thicker thiab muajmuaj zog corrosion kuj, uas yog haum rausiv sab nraum zoov mus ntev, tab sis qhov saum npoo yog rougher thiab cov tsos yog me ntsis zuj zus.

Cov khoom kho nrog kub-dip galvanizing yog dav siv hauv cov khoom siv xws li kev tsim kho, kev thauj mus los, hluav taws xob, kev lag luam hluav taws xob, tshuab thiab khoom siv hnyav, kev kho dej thiab ib puag ncig, kev tsim tsheb, kev ua liaj ua teb thiab ranch, thiab lwm yam. Piv txwv li, hauv elevator shafts:of elevator rails, rail brackets, cable brackets thiab brackets,Qhia rail txuas phaj, ncej steel qauv, guardrails thiab cov khoom siv kev nyab xeeb, cov khoom siv hluav taws xob thiab cov khoom siv teeb pom kev zoo, fasteners (bolts, ceev) kuj xav tau kub-dip galvanizing.
