Galvanized Hlau Txheej Txheem

Galvanized hlau yog ib hom hlau uas tau coated nrog ib txheej ntawm zinc los tiv thaiv xeb thiab ua kom muaj zog. Cov txheej txheem ntau lawm ntawm galvanized hlau muaj ob peb kauj ruam tseem ceeb:

1. Kev kos duab hlau - Thawj kauj ruam hauv cov txheej txheem tsim khoom suav nrog kev kos cov hlau los ntawm cov kab tuag kom txo tau nws txoj kab uas hla thiab ua tiav qhov xav tau loj thiab tuab.

2. Annealing - Tom qab cov hlau yog kos, nws yog annealed kom soften cov hlau thiab txhim kho nws ductility. Qhov no suav nrog cua sov xaim mus rau qhov kub thiab txias thiab tom qab ntawd cia nws txias maj mam.

3. Galvanizing - Cov kauj ruam tom ntej ntawm cov txheej txheem yog txheej txheej ntawm zinc. Qhov no yog ua los ntawm cov txheej txheem hu ua kub-dip galvanizing, qhov twg cov hlau yog immersed nyob rau hauv ib da dej ntawm molten zinc ntawm qhov kub ntawm ib ncig ntawm 450 degree. Cov zinc reacts nrog rau saum npoo ntawm cov hlau los tsim ib txheej nruj ntawm zinc-hlau alloy.

4. Ua kom txias - Thaum cov hlau tau galvanized, nws yog tom qab ntawd txias rau hauv lub tank quench uas muaj dej los yog cov tshuaj nruab nrab los tiv thaiv cov zinc los ntawm kev tawg lossis tev tawm.

5. Hlau spooling - Cov kauj ruam kawg hauv cov txheej txheem tsim khoom yuav tsum winding lub galvanized xaim mus rau spools rau kev thauj mus los thiab khaws cia.

Zuag qhia tag nrho, cov txheej txheem ntawm galvanized hlau yog ib qho nyuaj thiab ua tib zoo tswj cov txheej txheem uas yuav tsum tau muaj kev txawj ntse thiab cov khoom siv hauv lub xeev los tsim cov hlau zoo uas ua tau raws li cov qauv kev lag luam nruj tshaj plaws. Galvanized hlau yog dav siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim kho, kev ua liaj ua teb, thiab kev tsim khoom lag luam, ua tsaug rau nws cov kev tiv thaiv zoo heev rau corrosion thiab superior zog thiab durability.
