1.What yog qhov sib txawv ntawm cov qauv txheem?
SGCC: belongs rau tus qauv xov xwm Japanese (JIS G 3302). Tus qauv no muaj ntau heev hauv Nyiv, Tuam Tshoj (qhov twg tau saws los tau ua), Kaus Lim Qab Teb
S sawv rau hlau, g sawv rau galvanized, thawj c sawv rau kev ua lag luam / sib xws, thiab lub thib ob c sawv rau txias {0} {dov. Yog li, SGCC sawv rau "kev lag luam dav - qib kub {}} dip galvanized steel ntawv nrog txias- rolled puag."
DX51D: belongs rau European Txuj Ci (En 10346: 2015). Tus qauv no tau siv dav hauv Tebchaws Europe, Tebchaws Middle East, Africa, thiab cov tub rog loj hlob thiab cov phiaj xwm tau txais European txheem.
D sawv rau kev tsim qauv, x sawv rau txias {{kuas} poll, li qub), thiab d sawv rau qhov chaw zoo (haum rau feem ntau tsim cov txheej txheem). Yog li ntawd, dx51d sawv rau "kub - dip galvanized steel ntawv nrog kwv yees li ntawm 140 mpa, thiab zoo li qub zoo."
2.What yog qhov sib txawv ntawm cov ntsiab lus kev ua haujlwm?
SGCC (JIS G 3302):
Tsom Lub Ntsiab: Txheej Txheem Nyhav (Zinc Txheej Thickness) thiab cov khoom zoo. Tus qauv JIS muaj cov ncauj lus kom ntxaws ntxaws txo qhov ceeb toom (Z12, z18, Z22, ua qhov no yog qhov ntsuas qhov tseem ceeb no thaum xaiv cov khoom siv.
Cov cuab yeej ua kom yooj yim cov khoom ntiag tug Nws feem ntau ntsib kev ua lag luam dav dav thiab cov txheej txheem kev xav tau, tab sis tej zaum yuav tsis yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov sib sib zog nqus xws li SGCD muaj).
DX51D (EN 10346):
Tsom Lub Ntsiab: Kev Tsim Kho thiab Cov Cuab Yeej Siv Neeg Kho Mob. Cov tub ntxhais ntawm European Cov Qauv Kawm Ntawv EN 10346 yog qhov kev faib tawm ntawm Galvanized steel ntawv raws li kev sib sau ua ke zoo, xws li DX51D Cov khoom ntiag tug cov khoom ntiag tug: Muaj tseeb qhov yuav tsum muaj rau lub zog muaj zog, elongation, thiab lwm yam rau qhov yooj yim). TXHEEJ LUJ CEEB TSHEEJ: TXHEEJ TXHEEM LAWV TSEEM CEEB HEEV Cov txheej txheem European qhia txog kev sib xyaw ua ke ntawm cov txheej txheem code thiab cov txheej txheem txheej txheem. 3.Qhov dab tsi yog qhov sib txawv ntawm kev kho cov kev kho deg ntawm kev kho deg? SGCC: Cov kev kho deg yog feem ntau qhia los ntawm tus lej tom qab qib: SGCC (tsis muaj daim ntawv tshaj tawm): Feem ntau yog hais txog lub cev chromate passivation (ntiv tes {{}}} {resist resist {resist resist resist resisted), feem ntau. SGCC A: Qhia tias tsis tau kho (raws li cotreated (raws li coated), lub ntsiab lus roj tsuas yog, tsis passivated. SGCC B: phosphated. SGCC C: Rojed thiab Tshuaj kho. SGCC D: Tsis tau kho thiab tsis paub. DX51D: Cov kev kho deg sab saum toj yog kev sib txawv ntawm qib: + A: Tsis tau kho (raws li coated). + C: Chromated. + S: Roj. + CS: chromated thiab oiled - feem ntau. + M: Phosphated. 4.Qhov dab tsi yog qhov sib txawv ntawm qhov teeb meem hnyav npaum li cas yog qhia tawm? SGCC (JIS G 3302): Tsim raws li z ua tus lej, uas tus xov tooj sawv cev tsawg kawg nkaus tag nrho cov txheej hnyav (G / M²) ntawm ob sab. Piv txwv li: Z12: Tag nrho cov txheej hnyav ntawm ob tog ntau dua lossis sib npaug rau 120 g / m² (theoretical tsawg kawg ib sab yog kwv yees li 60 g / m²). Z18: Ntau dua lossis sib npaug rau 180 g / m². Z22: Muaj ntau dua lossis sib npaug rau 220 g / m². Z27: Ntau dua lossis sib npaug rau 275 G / M². DX51D (EN 10346): Qhia los ntawm "Z" ua raws li tus lej lossis "ZF" ua raws li tus lej. Tus lej no sawv cev rau qhov tsawg kawg txheej txo ib sab (G / M²). Z sawv rau ntshiab zinc txheej (zinc), thiab zf sawv rau zinc - stone (zinc- hlau). Piv txwv li: Z100: Ib Leeg {- sab ntau dua lossis sib npaug rau 100 g / m². Z140: Ib Leeg {- sab ntau dua lossis sib npaug rau 140 g / m². Z200: ib leeg - sab ntau dua los yog sib luag rau 200 g / m². Z275: ib leeg - sab ntau dua lossis sib npaug nrog JIS Z27 ob npaug {sab qhov hnyav ntawm 275 G / M²). 5.Qhov cov lus pom zoo xaiv? Yog hais tias corrosion lub neej (txheej tuab) yog qhov kev txhawj xeeb thawj thiab txoj haujlwm nyob rau sab hnub tuaj Asia, SGCC (teev Z tus nqi) yog ib qho kev xaiv zoo thiab feem ntau siv. Yog tias qee qib ntawm kev sib sau (khoov, stamping) yog koom nrog thiab cov phiaj xwm European, DX51d yog qhov pib zoo rau kev muaj. Yog tias yuav tsum tau muaj formability zoo dua, DX52D, DX52D, thiab lwm yam. Rau feem ntau cov qauv vaj tse, lub hnab ntawv tsim ua vaj tsev, thiab cov txee hauv tsheb (xws li z27) thiab muaj kev kawm zoo ib yam thiab tuaj yeem hloov pauv. Cov kev txiav txim siab tseem ceeb yog txheej qhov hnyav (ib leeg - {{{{} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {}} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {}} {} {} {} {} {} {} {} {} {} {} {} {} {} {
