Galvalume coil / Aluzinc coil / Zincalum coil yog Zn-Al alloy coated, thiab txheej txheej yog 55% Al, 43.3% Zn, thiab 1.6% Si.Bseides thawj xim, lub aluzinc coil muaj xiav, ntsuab, golden thiab liab xim.Rau nws zoo heev corrosion kuj, hom hlau no maj mam hloov galvanized steel thiab yog dav siv thoob plaws lub ntiaj teb no.
Qhov saum npoo yog du thiab muaj zoo heev atmospheric corrosion kuj.Nws atmospheric corrosion kuj yog 2-6 lub sij hawm siab tshaj ntawm cov kub-dip galvanized ntawv nrog tib txheej thickness.Nyob rau tib lub sijhawm, nws muaj qhov kub thiab txias corrosion kuj zoo ib yam li cov ntawv kub-dip aluminium ntawv, aluminium-zinc alloy coated steel ntawv Nws tuaj yeem siv rau lub sijhawm ntev ntawm qhov kub thiab txias li 315 ℃, thiab ntev. -lub sij hawm siv ntawm qhov kub ntawm 500 ℃ ~ 600 ℃;nws muaj dej tsis kam thiab av corrosion kuj, thiab nws cov dej corrosion kuj zoo dua li kub-dip galvanized ntawv thiab kub-dip aluminium ntawv.Av corrosion yog zoo dua li kub-dip galvanized ntawv;Nws muaj cov xim zoo nkauj thiab kev ua haujlwm zoo, thiab nws cov txheej txheem thiab kev sib txuas yog zoo ib yam li cov ntawv kub-dip galvanized, tuaj yeem ua tiav los ntawm kev khoov txias, stamping, thiab lwm yam, thiab muaj qhov zoo nkauj.
Aluminium-zinc alloy coated steel ntawv muaj ob qho tib si cov yam ntxwv ntawm kub-dip galvanized steel ntawv thiab kub-dip aluminium steel ntawv.Yog li ntawd, qhov twg kub-dip galvanized steel ntawv yog siv, aluminium-zinc alloy coated steel ntawv tuaj yeem siv, thiab nws tuaj yeem hloov cov ntawv kub-dip aluminium steel ntawv.Nws muaj ntau yam kev siv, xws li lub ru tsev panels, phab ntsa panels, lub teeb steel keels, cua sov radiators, lub tsheb lub cev, roj tso tsheb hlau luam, cable armored steel tapes, yas tsev cog khoom, granaries, shipping ntim, khoom siv hauv tsev thiab cov khoom siv, qhov cub, tawg -pov thawj steel siv, txheej npog ntawm cua txias thiab cua tshuab, hnub ci dej rhaub, ntim thawv rau cov khoom siv tshuaj, thiab xim phaj substrates, welded kav, steel qhov rais, txias-tsim steel cov ntaub ntawv nyob rau hauv metallurgical kev lag luam, thiab lwm yam., muaj ib tug dav heev thov kev cia siab.
Tus nqi ntawm aluminium-zinc alloy coated steel ntawv yog siab dua li ntawm cov ntawv zoo tib yam kub-dip galvanized steel ntawv, tab sis vim hais tias qhov tshwj xeeb lub ntiajteb txawj nqus ntawm txhuas yog me dua zinc, qhov tshwj xeeb nqus ntawm aluminium-zinc alloy txheej tsuas yog 3.75kg / dm3. , thaum lub ntiajteb txawj nqus ntawm zinc yog 7.1kg / dm3, yog li lub txheej hnyav Lub thickness ntawm aluminium-zinc alloy txheej ntawm 150g / m2 (ob-sided) yog tib yam li cov kub-dip galvanized steel phaj nrog cov txheej hnyav ntawm 275g / m2 (ob-sided), uas txuag tau nyiaj ntau dua txheej hlau.
Super corrosion kuj: corrosion kuj ntawm cov khoom yog 6-8 npaug ntawm cov ntawv galvanized, thiab nws yuav tsis xeb rau 20 xyoo nyob rau hauv ntau qhov chaw;
Kev kub siab oxidation tsis kam: kev siv tsis tu ncua lossis sib cuam tshuam hauv qhov kub thiab txias ntawm 315 degrees Celsius yuav tsis ua kom muaj xim lossis deformation;Kev siv tsis tu ncua lossis sib cuam tshuam hauv qhov kub thiab txias ntawm 490 degrees Celsius yuav tsis ua rau oxidize hnyav lossis tsim cov hlau oxide nplai;
High heat reflectance: Lub tshav kub ntawm cov khoom yog siab dua 75%, uas yog ob zaug ntawm cov ntawv galvanized;
Kev ua haujlwm yooj yim: nws tuaj yeem ua tau raws li kev ua haujlwm ntawm stamping, shearing, dabtsi yog khoov, thiab lwm yam .;
Zoo nkauj tsos: silver dawb snowflake qauv, zoo nkauj thiab zoo nkauj, tuaj yeem siv ncaj qha yam tsis muaj tha xim;
Nto txau: Nws yog ib qho zoo substrate rau xim txheej.Cov txheej txheem sib xyaw ntawm cov hlau alloy thiab cov khoom siv organic tuaj yeem muab kev tiv thaiv zoo dua thiab tiv thaiv corrosion nyob rau hauv cov txheej txheem organic.
