DX51D + Z yog ib qho ntawm ntau cov ntaub ntawv hauv cov ntawv galvanized. Nws tuaj yeem galvanized nrog lossis tsis muaj paj. Nws tsuas tuaj yeem yooj yim khoov thiab deformed. Cov uas xav tau kev kos duab sib sib zog nqus muaj xws li DX52D + Z, DX53...DX56D + Z, thiab lwm yam, thiab nws cov ntaub ntawv sib xws, DC51D + Z, DC52D + Z, ... thiab lwm yam. Nws tuaj yeem hais tias cov qauv siv sib txawv.
xwm 51d
Cov khoom xyaw tseem ceeb ntawm dX51d galvanized ntawv:
C% Tsawg dua lossis sib npaug rau {{0}}.07, Si% Tsawg dua lossis sib npaug rau 0.03, Mn% Tsawg dua lossis sib npaug rau 0.50, P% Tsawg dua lossis sib npaug rau 0.025, S% Tsawg dua lossis sib npaug rau 0.025, Alt% Ntau dua lossis sib npaug rau 0.020
Lub cev tseem ceeb ntawmdX51d galvanized ntawv:
① Kev ua haujlwm tsis zoo: Feem ntau hais lus, tsuas yog cov ntawv galvanized rau kev siv cov qauv, siv kos duab thiab cov nplooj ntawv tsis tshua muaj hlau muaj cov yam ntxwv ntawm lub zog. Ntawm lawv, cov ntawv galvanized rau cov qauv siv tau teev tseg nrog cov txiaj ntsig txwv, compressive zog thiab elongation, thiab lwm yam; rau cov ntawv tensile, tsuas yog elongation yog teev.
② Kev sim txoj kev: Ib yam li cov txheej txheem txias-kuav los tiag steel phaj kev sim.
③ Tensile test: Tensile test yog ib qho tseem ceeb los ntsuas qhov ua tau zoo ntawm cov ntawv hlau. Txawm li cas los xij, cov kev cai ntawm ntau lub teb chaws hauv ntiaj teb rau cov ntawv galvanized tsis zoo ib yam. Cov txheej txheem thoob ntiaj teb tsis qhia txog kev khoov tshwj tsis yog qib qauv. Folding thiab compressive zog sim. Hauv Nyij Pooj, tshwj tsis yog rau qib kev tsim qauv, kev tsim kho corrugated panels thiab corrugated vaj huam sib luag, yuav tsum tau kuaj tensile.
DX51D vs DC51D
DX51D stands rau galvanized steel ntawv. Thawj D txhais tau tias cov hlau tiaj tus rau kev sib sau txias. X txhais tau hais tias lub xeev dov tsis muaj qhov kawg. 51 yog tus naj npawb ntawm cov hlau. Qhov thib ob D txhais tau tias kub dipped galvanized.
Yog tias X tau C, uas yogdc51d ua, nws txhais tau hais tias lub substrate dov lub xeev yog txias dov. Thaum DD51D txhais tau hais tias dov lub xeev ntawm lub substrate yog kub dov.
Dab tsi ntxiv, nws yooj yim pom DX51D-Z, DX51D-ZF lossis DX51D-AZ. Z txhais tau hais tias lub galvanized txheej yog zinc. ZF txhais tau hais tias lub galvanized txheej yog Zn-Fe alloy. AZ txhais tau hais tias galvanized txheej yog galvalume.
DX51D galvanized coils yog tsim raws li EN 10346. Lub thickness ntawm zinc txheej txawv nyob ntawm seb cov neeg siv khoom xav tau.
