Dab tsi yog qhov txawv ntawm khaub thuas - rolled thiab kub- rolled daim ntawv galvanized?
Lub Hom Phiaj Xwm txiav txim siab cov tuab, nto zoo, thiab kev thov ntawm cov ntawv galvanized:
Txias -} rolled galvanized ntawv: lub substrate yog txias {}}} rolled steel (tuab 0.3-3.0 hli). Nws muaj qhov chaw du, thiab tsawg tuab tuab, thiab tuab tuab tuab sib txawv, ua rau nws haum rau cov khoom siv hauv tsev, tsheb, thiab qhov chaw ntsuas.
Kub -} rolled galvanized ntawv: lub substrate yog kub {}}} {4 {}} 12.0mm). Nws muaj qhov sib npaug ntawm thaj chaw (xav tau cov txheej txheem kom ntxaws ntxiv), cov tiaj tiaj tiaj, thiab yog tus nqi qis. Nws yog qhov haum rau kev siv vaj huam sib luag (xws li panels vov tsev, cov hlau nplaum), thiab cov khoom siv tshuab hnyav.
Hom twg ntawm galvanized ntawv feem ntau siv hauv kev tsim kho kev tsim kho, thiab yog vim li cas? Kub - dip galvanized (GI) steel ntawv nrog kub- panels, phab ntsa av, thiab purlins) rau cov laj thawj hauv qab no:
Nws cov tuab tuab ntau yam (3 - 12mm) tso cai rau nws kom tau raws li cov ris nra sib txawv - 5 hli rau purlins thiab 0.8-1.2mm rau vaj huam sib luag);
Cov txheej zinc txheej muaj qhov hnyav (120-275g / m²), muab muaj zog sab nraum zoov corrosion tawm tsam thiab xav tau tsawg zaus;
Its low cost (hot-rolled substrates are 20%-30% cheaper than cold-rolled substrates) makes it suitable for large-scale construction applications;
Qee qhov siab -}} End Architecture Zoo nkauj Panels siv Gi lossis EG substrates, coated nrog zaj duab xis los txhim kho lawv cov loog.
Dab tsi yog hom ntawm Galvanized steel ntawv feem ntau siv hauv cov khoom siv hauv tsev? Dab tsi yog lawv siv rau? Lub tsev hauv tsev kev lag luam xav tau cov khoom zoo thiab muaj peev xwm, thiab peb hom hlau galvanized yog siv:
Cov hlau hluav taws xob hluav taws xob (piv txwv li): Siv rau hauv tub yees sab panels thiab tshuab ntxhua khaub ncaws tswj panels. Nws txoj kev ncaj ncaj ua kom nws yooj yim pleev xim thiab haum rau cov chaw pw hauv tsev.
Txias -} kub - dip galvanized steel (GI): Siv cua txias sab nrauv tsev. Nws muaj kev ua kom zoo dua rau piv txwv li thiab qis dua GA.
Alloy - dip galvanized steel (GA): Siv nyob rau hauv high-}}}} condition end condition compress້ນ txuas rau hauv lub nruas thiab cua txias compressor tsev. Nws muaj zoo heev weldability thiab kos tiv thaiv, ua rau nws haum rau high- zaus Cheebtsam.
Vim li cas GA nyiam nyob rau hauv kev lag luam tsheb? GA feem ntau yog siv rau lub cev carrotive (xws li lub qhov rooj thiab hoods) thiab cov cheebtsam chassis. Cov laj thawj tseem ceeb yog:
Zoo tshaj Weldability: qhov tsis muaj zinc txheej tiv thaiv zinc tawg thiab hws kom haum vuam, ua kom haum rau cov kab ntau lawm (high efficiency);
Muaj zog txheej adhesion: lub cev yuav tsum tau pleev xim, thiab ga zinc txheej, daim ntawv sib dhos nrog cov xim ntau dua 30% zoo dua li GI, ua rau tsawg dua li green peeting;
Zoo heev cuam tshuam: GA Zinc Txheej muaj kev nruj me ntsis, tiv thaiv nws los ntawm flaking vim kev tshee thiab kev sib tsoo me thaum tsav tsheb;
Ib co chassis Cheebtsam (xws li cov ncej) siv cov txheej zinc hnyav
Yuav ua li cas ceev faj yuav tsum tau noj thaum khaws cia galvanized ntawv? Yuav tsum zam cov teeb meem twg?
Cov ntaub ntawv tsis raug yuav ua rau zinc oxidation thiab corrosion. Plaub lub ntsiab lus tseem ceeb yuav tsum tau txiav txim siab:
Kev tswj hwm ib puag ncig: khw hauv ib qho qhuav, zoo - ventatated chav nrog tsawg dua los yog sib npaug rau 60%. Zam txhob muaj nag los yog kev tshav ntuj.
Noog noo - Ua pov thawj: Txhawb nqa cov laug cam nrog rau 10cm ntawm av) los tiv thaiv ya raws hauv av.
Tsis txhob muaj kev tshaj tawm: Cov ntawv tiaj tus nplooj ntawv tiaj tsawg dua lossis sib npaug ntawm 1.5m siab dua lossis sib npaug los tiv thaiv kev deformation ntawm cov laug cam thiab kos rau ntawm zinc txheej.
Cais tawm ntawm corrosion los: Khw kom deb ntawm cov tshuaj acidic thiab alkaline (xws li chiv thiab tshuaj lom neeg cov khoom nyoos) txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshuaj zinc txheej.
Cov teeb meem uas nquag: Dawb siav (zinc oxidation) tej zaum yuav tsim tawm tom qab 2-3 lub hlis hauv kev thaj chaw noo. Yuav tsum tau tshuaj xyuas ib txwm muaj, thiab ib qho xeb dawb yuav tsum tau so nrog daim ntaub qhuav.
