Muaj ob peb txheej txheem uas yuav siv tau rau galvanize hlau : kub-dip galvanizing , electrogalvanizing, sherardizing, thiab txau xim hlau.

Txias lub galvanized hlau.

  1. Immerse cov hlau hauv kev daws teeb meem xws li potassium hydroxide.
  2. Raus dej hlau hauv dej.
  3. Let cov hlau txias hauv qhov qhib cua.

Kuj tseem paub yog, galvanized steel li cas?

Galvanized hlau yog carbon hlau uas tau coated nrog zinc. Cov txheej txheem feem ntau ntawm txheej zinc yog txheej txheem kub-dip. Thaum cov khoom raug tshem tawm ntawm cov da dej zinc thiab ua kom txias ua rau cov pa oxygen hauv huab cua tshwm sim. Cov tshuaj tiv thaiv ua rau zinc los ua ib feem ntawm cov hlau (Iron-zinc alloy daim ntawv cog lus).

Ib yam li ntawd, nws raug nqi npaum li cas rau galvanize steel? Hlau ntawm no thickness muaj thaj tsam ntawm 20 m2 / tonne, yog li cov nqi ntawm galvanizing ib square meter yog $ 40. Lub teeb hlau ua haujlwm, feem ntau cuam tshuam nrog lub thawv rau khoom, lossis lub teeb hollow ntu uas qhov nruab nrab 3 hli hauv tuab tuaj yeem ua tau nqi $ 1500/tonne rau galvanize.

Yog li ntawd, nws yuav siv sij hawm ntev npaum li cas rau galvanize steel?

Galvanizing leadtimes tuaj yeem sib txawv nyob ntawm lub sijhawm ntawm lub xyoo thiab qhov xav tau ntau npaum li cas hauv kev lag luam, txawm li cas los xij feem ntau cov xaj yuav ua tiav hauv ib lub lis piam. Cov txheej txheem tiag tiag ntawm Kub Dip Galvanizing siv kwv yees li ib nrab hnub txij thaum pib kom tiav yog li cov khoom siv maj nrawm feem ntau ua tiav hauv 24 - 48 teev.

Puas tuaj yeem kov cov hlau thiab txhuas?

“Nco ntsoov tias txhuas yog nyob ze ntawm kev ua si nrog hlau . Txawm li cas los xij, lawv tseem yog cov hlau tsis sib xws thiab raug cuam tshuam rau galvanic corrosion thaum nyob rau hauv kev sib cuag hauv qhov chaw corrosive. Yog tias muaj qhov xwm txheej no, cov hlau ua haujlwm me me tuaj yeem corrode ntawm tus nqi nrawm.
