Galvanized Steel Structures, Yeeb Nkab & Fittings
Peb cov khoom muaj xws li kub-dip galvanized (HDG) steel qauv, galvanized raj fittings, dav siv nyob rau hauv kev tsim kho, fais fab, telecom, tsheb thauj mus los, nroog, roj & roj, thiab offshore industries. Ua los ntawm cov qib siab - zoo carbon steels (xws li, Q235, Q355, S235JR), cov khoom yog immersed nyob rau hauv molten zinc los ua ib tug ntom, uniform, thiab muaj zog adherent zinc- hlau alloy txheej, muab superior corrosion kuj, ntev kev pab cuam lub neej, thiab txij nkawm- ua haujlwm dawb. Cov txheej zinc ua raws li kev txi anode, tiv thaiv lub hauv paus hlau txawm tias ntawm cov npoo los yog khawb, ua rau nws nyiam cov kev daws teeb meem rau kev lag luam thiab kev tiv thaiv corrosion.

Cov Lus Nug Rau Cov Neeg Siv Khoom (Q&A Hom)
Q: Qhov txawv ntawm kub-dip thiab electro-galvanizing yog dab tsi?
A: HDG muaj txheej tuab (50-150μm), zoo corrosion kuj; electro-galvanizing yog thinner (5–25μm), siv rau sab hauv tsev / hniav qhov chaw.
Q: Cov txheej thickness puas tuaj yeem nce?
A: Yog, los ntawm kev immersion ntev dua, kub dua, lossis Galfan alloy, haum rau qhov chaw hnyav.
Q: Can galvanized steel welded?
A: Yog, tab sis qhov chaw weld poob zinc tiv thaiv; zinc-nplua nuj xim los yog tshuaj tsuag zinc yuav tsum tau kho.
Q: Cov kav dej galvanized puas muaj kev nyab xeeb rau cov dej haus?
A: Yog lawm, tom qab pib yaug; ua raws li GB / T 3091 thiab cov qauv kev nyiam huv.
Q: Ntev npaum li cas HDG nyob hauv ib puag ncig marine?
A: Zinc noj tus nqi: 3-5μm / xyoo; 85μm txheej kav 15-25 xyoo.
Q: Koj puas muab kev pabcuam galvanizing?
A: Yog, peb muab tus xov tooj galvanizing rau cov neeg siv khoom- khoom siv, OEM txhawb nqa.
Q: Puas yog xeb dawb li qub?
A: Yog, nws yog zinc oxide; nws stabilizes thaum qhuav. Ntxuav nrog hlau txhuam yog tias hnyav heev.
Q: Puas tuaj yeem pleev xim rau galvanizing?
A: Yog lawm, tom qab phosphating lossis sandblasting kom zoo dua adhesion ("duplex system").
Q: Lub sijhawm ua haujlwm yog dab tsi?
A: Cov kav dej: 7-15 hnub; cov qauv: 10-20 hnub.
Q: Koj puas muab cov ntaub ntawv tshuaj xyuas txheej txheem?
A: Yog, suav nrog DFT, adhesion, thiab kev kuaj pom ib GB / T 13912 lossis ASTM A123.
Q: haum rau siab -siab tshuab?
A: Fittings yog rau qis - siab (Class 150); siab - siab yuav tsum tau seamless kav los yog lwm txoj kev tiv thaiv.
Q: Yuav ua li cas tiv thaiv kev puas tsuaj thaum lub sij hawm xa khoom?
A: Ntoo crates, kawg kaus mom, mos padding, tsis txhob ncaj steel hlua tiv tauj.
