Kub Dipped Galvanizing txheej txheem yog txheej txheem ntawm txheej txheej hlau nrog txheej zinc los tiv thaiv corrosion. Cov txheej txheem no yog tshwj xeeb tshaj yog haum rau steel thiab hlau cov ntaub ntawv, raws li nws zoo txuas lub neej ntawm cov khoom thiab txhim kho nws corrosion kuj. Cov txheej txheem dav dav ntawm kub-dip galvanizing suav nrog cov kauj ruam hauv qab no:
1. Kev kho mob ua ntej: Cov khoom siv hlau yog thawj zaug rau kev kho mob saum npoo av, uas feem ntau suav nrog kev tu, degreasing, pickling thiab flux daim ntawv thov kom ntseeg tau tias cov hlau nto yog huv si thiab tsis muaj impurities.
2. Dip Plating: Cov hlau pre-kho yog immersed nyob rau hauv ib tug molten zinc tov rhuab mus txog 435-530 ° C. Tom qab ntawd cov hlau yog dipped rau hauv ib lub molten zinc da dej. Thaum qhov kub thiab txias, cov hlau nto reacts nrog zinc los tsim cov zinc-hlau alloy txheej, txheej txheem uas zinc ua ke nrog cov hlau nto los tsim ib daim ntawv cog lus metallurgical.
3. Kev ua kom txias: Tom qab cov hlau raug tshem tawm ntawm cov zinc tov, nws yuav tsum tau txias, uas tuaj yeem ua tiav los ntawm kev ua kom txias, dej txias lossis cua txias.
4. Kev kho tom qab: Cov hlau txias galvanized yuav xav tau kev tshuaj xyuas thiab kev kho mob ntxiv, xws li tshem tawm cov zinc ntau dhau, passivation los txhim kho corrosion, thiab oiling los yog lwm yam kev kho deg los muab kev tiv thaiv ntxiv.
Cov khoom ntawm cov khoom kub-dip galvanized muaj xws li zoo heev corrosion kuj, zoo workability thiab zoo nkauj zog. Lub xub ntiag ntawm zinc txheej tiv thaiv cov hlau los ntawm corrosion los ntawm qhov kev txiav txim ntawm kev txi anode, txawm tias zinc txheej puas lawm. Tsis tas li ntawd, cov txheej txheem kub-dip galvanizing txheej txheej yuav tsim cov zinc-hlau alloy theem txheej txheej los ntawm kev tawg ntawm cov hlau puag saum npoo los ntawm zinc tov, ntxiv diffusion ntawm zinc ions nyob rau hauv lub alloy txheej rau hauv lub substrate los tsim ib tug zinc-hlau intercalation txheej, thiab tsim ib tug ntshiab zinc txheej nyob rau saum npoo ntawm alloy txheej.
Kub-dip galvanizing yog siv dav hauv ntau daim ntawv thov, suav nrog kev tsim vaj tsev, kev thauj mus los, metallurgy thiab mining, kev ua liaj ua teb, tsheb, khoom siv hauv tsev, cov khoom siv tshuaj lom neeg, kev ua roj av, kev tshawb nrhiav dej hiav txwv, cov qauv hlau, kev xa hluav taws xob, nkoj tsim thiab lwm yam haujlwm. Cov txheej txheem tshwj xeeb rau cov khoom kub-dip galvanized muaj xws li cov txheej txheem thoob ntiaj teb ISO 1461-2009 thiab Suav teb chaws tus qauv GB / T 13912-2002, uas qhia meej cov kev cai rau lub thickness ntawm kub-dip galvanized txheej, qhov ntev ntawm cov profile thiab cov nto zoo.
