Daim Ntawv Qhia Txog Kev Ua Yeeb Yam ntawm Txias Txias Rolled Steel Ntawv thiab Galvanized Steel Sheet
1. Qhov tseeb ntawm kev thov cov xwm txheej
(1) zoo ntawmCold Rolled Steel Sheet
Vim tias cov ntawv txias rolled steel tsis muaj anti - corrosion txheej, nws haum rau cov xwm txheej hauv qab no:
Qhov chaw uas yuav tsum tau ua ntxiv: piv txwv li lub cev tsheb (xav tau electrophores + rooj tog zaum (xav tau hmoov hmoov). Cov ntawv du ntawm cov kab hlau txias
Cheeb Tsam Sab Hauv: Cov Txheej Txheem Sab Hauv Ntawm Cov Machinery, xws li cov xwm txheej hluav taws xob (tsis txhob xeb cov kev pheej hmoo.
Qhov chaw yuav tsum tau sib sib nqus: cov vaj tse muaj roj av, dej haus tuaj yeem lub cev. Mos txias dov steel ntawv muaj siab elongation (tshaj 30%), enable kev sib sau.
Piv txwv li, lub tsev tsim khoom tsheb siv tau 0.8 hli txias dov steel ntawv (spcc- d) rau cov khoom siv sab hauv. Tom qab stamping thiab electrophoretic txheej, nws ua kom raug kev tiv thaiv raug thiab ua tiav corrosion tiv thaiv los ntawm txheej, nrog tus nqi 15%-qis dua li siv cov hlau galvanized.
(2) Cov ntawv thov tseem ceeb ntawm Galvanized steel ntawv
Ua tsaug rau nws corrosion tsis kam, galvanized steel ntawv uas dominates cov teb nram qab no:
Sab nraum zoov cov chaw puag ncig: lub ru tsev (0.3-0.8 mm kub- pa taws galvanized), 2.0 mm kub- dip galvanized). Cov cua daj cua dub thiab nag tsis muaj dua ntxiv anti - corrosion kho.
Cov chaw lim dej noo: Tshuab Ntxhua Khaub Ncaws (Electro - galvanized), Kub}} noo noo galosion nrog kev pabcuam lub neej ntawm ntau tshaj 10 xyoo.
Cov xwm txheej uas yuav tsum tau ua tiav Post -}} Kev kho mob: Cia Racks, Kev Muaj Khoom Pallets. Lawv tuaj yeem siv ncaj qha yam tsis muaj kev pleev xim, txo tus nqi, thiab yog ib qho yooj yim tswj (cov xeb hauv zos tuaj yeem kho nrog zinc- nplua nuj xim).
Piv txwv li cov chaw logistics siv tau 1.5 hli kub - dip galvanized steel ntawv (zinc txheej steelized (zinc txheej 180 g / m²) rau cia racks. Tom qab 5 xyoo nyob rau hauv lub tsev khaws khoom noo, tsis muaj ib qho tseem ceeb corrosion, thaum racks ua los ntawm cov khoom txias uas tau pom cov xeb loj thiab yuav tsum tau hloov tag nrho.
2. Cov ntsiab lus tseem ceeb hauv kev xaiv cov kev txiav txim siab
Thaum xaiv ntawm cov ntawv txias dov steel thiab galvanized steel ntawv, cov hauv qab no yuav tsum tau txiav txim siab:
Ib puag ncig cov ntsiab lus: rau sab nraum zoov lossis vaum ib puag ncig, galvanized steel ntawv yog nyiam; Rau sab hauv chaw qhuav, cov ntawv txias siv hlau tuaj yeem raug xaiv.
Kev ua cov kev ua: rau kev teeb duab sib sib zog nqus thiab siab - precision txheej, txias rolled steel ntawv yog pom zoo; Rau cov qauv yooj yim yam tsis muaj txheej ntxiv, galvanized steel ntawv yog qhov haum ntau dua.
Kev Xam Ua Nqi: Rau luv - tsis siv (<5 years), cold rolled steel sheet is cost-effective; for long-term use (>10 xyoo), galvanized steel ntawv muaj tus nqi zoo dua.
Piv txwv li, cov ntaub ntawv nyob sab hauv tuaj yeem ua tau nrog 0.8 hli txias rolled steel ntawv (nrog hmoov txheej), uas yog tsawg- tus nqi thiab ua kom zoo nkauj; Sab nraum zoov cov pob tw khib nyiab yuav tsum siv 1.0 hli kub- dip galvanized steel ntawv kom tsis txhob corrosion nquag thiab hloov.
Galvanized steel ntawv thiab khaub thuas dov steel ntawv yog tsis hloov tab sis theej cov khoom sib txawv hauv cov hlau ua cov saw hlau. Txias rolled steel ntawv yog "yooj yim version," kev xaiv ntau yam kev ua tau zoo. Galvanized steel ntawv yog lub "hloov kho tshiab," tsom rau daws teeb meem corrosion. Nkag siab txog lawv cov txheej txheem sib txawv, thiab cov yam ntxwv ua tau zoo hauv kev xaiv, thiab cov nqi ua kom tiav rau cov khoom siv.
