Dab tsi yog qhov txawv ntawm ga thiab gi galvanizing?

I. Qhov tseem ceeb ntawm GA thiab GI galvanizing cov txheej txheem
1. GI (galvanized hlau):

-}} Siv cov txheej txheem hluav taws xob (electrolytic zinc plating), Zinc Plating), Zinc Wons yog tso rau ntawm cov hlau saum npoo los ntawm hluav taws xob tam sim no. Cov txheej txheej txheej tuab yog ib txwm 3-20μm.

{{0- NTA: Ib qho chaw du thiab tsis muaj txiaj ntsig rau cov hluav taws xob (xws li corrosion qhov chaw (

2. GA (galvannealed):

-}}} Siv kub}} dip aluminium, raws li cov khoom silicon, raws li txheej xyov yog 20-150μm.

{{0- NTA: Cov Txheej Txheem thiab Cov Ntawv Hlau Rho Tawm (2-3 zaug siab dua GI), tab sis qhov chaw siab dua rau cov khoom siv sab nrauv thiab yog feem ntau.

Hauv cov ntsiab lus: GI yog electrogalvanized, thaum GA kub - dip aluminium {}} dinc. Ob txoj kev ua thiab cov khoom sib xyaw ua ke sib txawv.

Ii. Core kev ua tau zoo sib piv ntawm GA thiab GI
1. Corrosion Kuj (Kev Ntsuas Ntsev Txau):

{{0- gi: rust zoo tshwm nyob rau hauv kwv yees li 48 teev (Astm B117).

{{0- ga: dawb xeb tshwm hauv 100 teev lossis ntau dua, thiab txhuas tuaj yeem tsim zaj duab xis passive.

2. Nqi thiab txheej txheem:

{{0- gi yog tus nqi qis (kwv yees li 15% -20% pheej yig dua li ga), tab sis nws yog ib qho uas ua rau zinc vapor thaum vuam.

{{0- ga yog siab - tiv taus kub (tuaj yeem tiv taus kub tshaj 300 degree) thiab haum rau pleev xim thiab stamping.

III. Yuav ua li cas xaiv GA lossis GI?

{{0- Gi: Thaum koj xav tau pheej yig, du -} surfaced Cheebtsam (xws li bolts thiab chassis).

{{0- ga: thaum koj xav tau huab cua siab thiab ntev}}}} coated steel subtrates).

Gnee steel, ib lub tuam txhab kev xa tawm tsim tau nyob rau xyoo 2008, tau cog lus los muab cov khoom lag luam siab thiab cov kev pabcuam rau cov neeg siv khoom thoob ntiaj teb rau ib xyoo caum.

Peb cov khoom tseem ceeb suav nrog galvanized steel coils,Galvanized Steel Ntawv, galvanized kav, steel gratings, thiab lwm yam, uas tau siv dav hauv kev tsim kho, kev thauj mus los, thiab kev lag luam khoom siv. Cov khoom lag luam tau raug kev ntsuas zoo thiab ua tau raws li cov qauv thoob ntiaj teb.
