Qhov zoo thiab qhov tsis zoo ntawm aluminium-zinc plated steel phaj

Kub dip galvanized steel tau siv dav hauv kev tsim kho, khoom siv hauv tsev thiab lwm yam lag luam loj txij li thaum nws tshwm sim. Vim qhov kev nthuav dav ntawm kev siv tas mus li, kev tsim thiab ntau yam khoom ntawm cov khoom siv rau cov hlau phaj tau txhim kho tas li, thiab cov txiaj ntsig aluminium-zinc plated steel phaj yog superior rau kub-dip galvanized steel phaj hauv qee yam khoom. Aluminium-zinc plated steel phaj
Al-Zn composite aluminium-zinc plated steel phaj yog tau los ntawm kub-dip plating nrog txias-kuav los tiag nyuaj steel phaj ntawm ntau lub zog thiab thickness specifications raws li cov khoom siv hauv paus. Cov txheej muaj 55% aluminium, 43.5% zinc, 1.5% silicon thiab lwm yam kab kawm.
Hauv kev tsim thiab ua cov txheej txheem, kev ua haujlwm ntawm aluminium-zinc plating yog qhov zoo tshaj plaws ntawm kub-dip galvanizing, feem ntau hauv cov hauv qab no.
Kev ua tau zoo
Kev ua tau zoo ntawm aluminium-zinc plated steel phaj zoo ib yam li kub-dip galvanizing, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm dov, stamping, dabtsi yog khoov thiab lwm yam ntaub ntawv.
Corrosion kuj
Qhov kev ntsuam xyuas yog ua nyob rau hauv lub premise ntawm kub-dip galvanized steel ntawv thiab txhuas-zinc coated steel ntawv nrog tib thickness, txheej thiab nto kho. Aluminium-zinc plating muaj corrosion kuj zoo tshaj li kub-dip galvanizing, thiab nws cov kev pab cuam lub neej yog 2-6 npaug ntawm zoo tib yam galvanized steel phaj.
Lub teeb pom kev zoo
Lub peev xwm ntawm aluminized zinc kom muaj kev cuam tshuam txog cua sov thiab lub teeb yog ob zaug ntawm galvanized steel phaj, thiab qhov kev xav tau ntau dua 0.70, uas zoo dua 0.65 teev los ntawm EPA Enerav Star
Thaum tshav kub kub kuj
Cov khoom siv kub-dip galvanized feem ntau yog siv los ntawm qhov kub tsis tshaj 230 ℃, thiab yuav hloov xim ntawm 250 ℃, thaum txhuas-zinc phaj tuaj yeem siv tau ntev ntawm 315 ℃ tsis hloov xim. Tom qab 120 teev ntawm 300 ℃, cov xim hloov ntawm aluminium-zinc plated steel phaj kho los ntawm tshav kub-tiv taus passivation ntawm Baosteel yog qis dua li ntawm txhuas phaj thiab txhuas-plated phaj.
mechanical khoom
Cov khoom siv hluav taws xob ntawm aluminium-zinc plated steel phaj yog feem ntau tshwm sim hauv kev tawm dag zog, lub zog tensile thiab elongation. Ordinary DC51D galvanized steel phaj ntawm 150g / m2 muaj lub zog tawm los ntawm 140-300mpa, lub zog tensile ntawm 200-330 thiab elongation ntawm 13-25. Tus naj npawb DC51D + AZ
Lub zog tawm ntawm aluminized zinc plated steel ntawv nrog 150g / m2 aluminized zinc yog nruab nrab ntawm 230-400mpa, lub zog tensile nyob nruab nrab ntawm 230-550, thiab elongation rail yog nyob nruab nrab ntawm 15-45.
Vim tias txhuas-zinc txheej yog cov hlau nplaum uas muaj qhov ntom ntom ntom ntom ntom ntom ntom, nws muaj ntau yam zoo thiab qee qhov tsis xws
1. Kev ua haujlwm vuam
Vim tias qhov nce ntawm cov neeg kho tshuab, cov txheej ntom ntom ntom ntom nti yog qhov zoo, yog li cov ntsiab lus manganis yog qhov zoo heev, yog li tsuas yog txuas los ntawm rivets thiab lwm pawg. Nyob rau hauv cov nqe lus ntawm vuam, kub-dip galvanized steel phaj ua tau zoo, thiab tsis muaj teeb meem vuam.
2. Kev tsim nyog ntawm qhov kub thiab txias ua vaj tse
Cov txheej txheem ntawm aluminium-zinc txheej muaj cov txhuas, uas yog cov tshuaj lom neeg cov tshuaj tiv thaiv hauv kev sib cuag ncaj qha nrog cov kua qaub ntub dej. Yog li ntawd, nws tsis yog tsim nyog los ua cov boards hauv pem teb.
