Dab tsi yog qhov zoo ntawm Galvanized Steel Sheets?

Galvanized steel ntawv yog welded steel ntawv nrog kub-dip galvanized lossis electro-galvanized txheej ntawm qhov chaw. Nws feem ntau yog siv dav hauv kev tsim kho, khoom siv hauv tsev, tsheb thiab nkoj, ntim khoom, thiab kev lag luam electromechanical. Yog li dab tsi yog qhov zoo ntawm galvanized steel ntawv?
1. Kev ua tau zoo: Kev ua haujlwm ntawm cov ntawv hlau galvanized zoo ib yam li cov 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.
2. Corrosion resistance: Qhov kev ntsuam xyuas yog ua raws li qhov chaw ntawm kub-dip galvanized steel los xij thiab galvanized steel los xij nrog tib lub thickness, txheej, thiab kev kho deg. Galvalume muaj kev tiv thaiv corrosion zoo dua li kub-dip galvanizing, thiab nws lub neej kev pabcuam yog 2-6 npaug ntawm cov hlau galvanized zoo tib yam.
3. Lub teeb pom kev zoo: lub peev xwm ntawm cov hlau galvanized los cuam tshuam cov cua sov thiab lub teeb yog ob zaug ntawm cov hlau galvanized, thiab qhov kev xav tau ntau dua li 0.70, uas zoo dua li 0.65 teev los ntawm EPA Lub Hnub Qub Zog (Lub Hnub Qub Zog ntawm US Environmental Protection Agency).
4. Thaum tshav kub kub tsis kam: Cov khoom siv kub-dip galvanized feem ntau yog siv los ntawm qhov kub tsis tshaj 230 degrees, thiab xim yuav hloov ntawm 250 degrees, thaum daim ntawv galvanized tuaj yeem siv tau ntev yam tsis muaj xim nyob rau hauv ib puag ncig ntawm 315 degrees. . Nyob rau hauv ib puag ncig ntawm 300 degrees rau 120 teev, cov xim hloov ntawm Baosteel lub tshav kub-resistant passivation-kho galvanized steel phaj yog qis dua li ntawm txhuas phaj thiab txhuas plated phaj.
5. Cov khoom siv kho tshuab: Cov khoom siv hluav taws xob ntawm cov ntawv hlau galvanized feem ntau yog tshwm sim hauv kev tawm dag zog, lub zog tensile thiab elongation. Ordinary DC51D qib 150 g/square galvanized steel ntawv, lub zog tawm los ntawm 140-300mpa, lub zog tensile nyob nruab nrab ntawm 200-330, thiab elongation yog nruab nrab ntawm 13-25. Lub zog tawm ntawm DC51D ntxiv rau AZ galvanized 150 g / square galvanized steel phaj yog nruab nrab ntawm 230-400mpa, lub zog tensile nyob nruab nrab ntawm 230-550, thiab elongation rail yog nruab nrab ntawm 15-45.
