1. Ordinary ntshiab zinc txheej khoom (GI) Ordinary kub-dip galvanized cov khoom tuaj yeem muab faib ua spangle zoo tib yam, me me spangle, tsis muaj spangle thiab du nto khoom raws li lub xeev nto.Vim nws qhov zoo corrosion kuj, kev ua haujlwm zoo heev thiab kev ua haujlwm zoo, tsis tshua muaj nqi, thiab zoo nkauj tsos, nws yog dav siv hauv kev tsim kho, tsheb, khoom siv hauv tsev thiab lwm yam lag luam.Tshwj xeeb tshaj yog rau me me spangle thiab tsis muaj spangle txheej cov khoom, cov khoom saum npoo yog zoo, ntom, du, thiab muaj cov txheej txheem zoo dua thiab corrosion kuj, tshwj xeeb tshaj yog rau cov khoom siv hauv tsev, xim txheej thiab lwm yam lag luam.
2. Zinc Aluminium Alloy Coated Sheet (GF)
Zinc-aluminium alloy coated ntawv tseem hu ua low-aluminium galvanized steel ntawv, thiab txheej muaj
5% Al, 95% Zn, thiab cov cim ntawm lub ntiaj teb tsis tshua muaj.Qhov zoo tshaj plaws yog tias cov yas thiab adhesion ntawm txheej yog zoo heev, thiab corrosion kuj ua ntej thiab tom qab deformation tsis hloov;atmospheric corrosion kuj yog 2 mus rau 3 npaug ntawm cov pa kub-dip galvanized los xij, thiab nws muaj coatability zoo thiab weldability.Ntawm tag nrho cov ntawv galvanized, nws muaj qhov zoo tshaj plaws toughness, corrosion kuj thiab formability piv rau electro-galvanized los xij.Cov khoom no tsuas yog siv rau corrosion-resistant thiab huab cua-resistant ib puag ncig thiab txheej txheej substrates.
3.Aluminium-zinc alloy coated phaj (GL) txheej txheej ntawm aluminium-zinc alloy coated phaj yog Al-Zn alloy, thiab txheej txheej yog 55% Al, 43.3% Zn, 1.6% Si.Nws nto yog du thiab muaj kev tiv thaiv zoo heev atmospheric corrosion, uas yog 2-6 npaug siab dua li tib daim ntawv kub-dip galvanized.Nws muaj qhov kub thiab txias corrosion kuj zoo ib yam li kub-dip aluminium phaj, thiab tuaj yeem siv tau ntev yam tsis muaj xim lossis deformation ntawm qhov kub ntawm 315 degrees.Cov dej corrosion kuj zoo dua li ntawm cov ntawv kub-dip galvanized thiab cov ntawv kub-dip aluminized, thiab cov av corrosion kuj zoo dua li ntawm cov ntawv kub-dip galvanized.Nws thermal reflectivity yog siab dua 75%, uas yog ob zaug ntawm cov ntawv zoo tib yam galvanized.Nws muaj cov xim zoo nkauj thiab kev ua tiav, thiab maj mam hloov cov ntawv galvanized thiab tau siv dav hauv ntiaj teb.
4. Kub-dov galvanized ntawv - kub dov galvanized ntawv yog ib daim ntawv galvanized uas ua ncaj qha los ntawm pickling thiab galvanizing nrog kub-kuav los tiag ntawv raws li lub substrate.Lub rooj tsavxwm tuaj yeem siv dav hauv kev tsim kho, tsheb, steel silos, railway neeg nrog caij tsheb, txoj kev loj guardrail boards, thiab lwm yam. Tam sim no, domestic ntau lawm ntawm kub dov galvanized ntawv yog me me, thiab feem ntau ntawm cov galvanized ntau lawm kab uas tau raug ua tiav thiab muab tso rau hauv kev tsim khoom yog galvanized ntawv nrog cov ntawv txias dov raws li cov substrate.Piv nrog rau cov ntawv txias-dov galvanized, qhov sib txawv ntawm kev ua haujlwm ntawm cov ntawv kub-dov galvanized thiab cov ntawv txias-dov galvanized tsis loj heev.Vim tias cov ntawv kub dov galvanized txuag cov txheej txheem txias dov, cov nqi tsim khoom qis dua, thiab nws muaj txiaj ntsig zoo dua.
