Kev ua tau zoo ntawm aluminium zinc magnesium txheej
1. Zoo heev corrosion kuj:
Raws li cov ntaub ntawv, aluminium-zinc-aluminium-magnesium txheej tau zoo dua dav hlau corrosion tsis kam tshaj galvalume thiab kub-dip ntshiab zinc. Nyob rau hauv nruab nrab ntsev tsuag tshuaj ntsuam tej yam kev mob, lub sij hawm rau liab xeb tshwm nyob rau hauv txhuas-zinc- txhuas-magnesium coatings yog nyob rau nruab nrab ntau tshaj 50% ntev tshaj li cov galvanized txheej nrog tib txheej thickness. Kev tiv thaiv corrosion yog 10 mus rau 20 npaug ntawm kub-dip galvanized steel daim hlau, thiab 5 mus rau 8 npaug zoo dua kub-dip galvanized-5% aluminium alloy steel daim hlau.
Notch Corrosion Resistance High Al-Zn Al-Mg txheej muaj qhov zoo dua corrosion tsis kam tshaj Al-Zn txheej. Nyob rau hauv nruab nrab ntsev tsuag tshuaj ntsuam tej yam kev mob, qhov ntau dua cov zinc piv Performance index, qhov ntau dua qhov kev txhim kho corrosion kuj ntawm high-aluminium-zinc-aluminium-magnesium txheej hla lub notch ntawm aluminium-zinc txheej.
2. Zoo heev stamping processability
Piv nrogkub-dip galvanized steel ntawv, nws txheej muaj siab hardness thiab du nto, yog li nws cov stamping kev ua tau zoo heev, yog li txhim kho ntau lawm efficiency.
Cov npoo npoo tom qab ua tiav ntawm zinc-aluminium-magnesium me me, → qhia qhov zoo tshaj plaws stretch forming zog ntawm zinc-aluminium-magnesium.
3. Txo cov nqi
Qhov zoo tshaj plaws corrosion kuj ntawm zinc, aluminium thiab magnesium tso cai rau cov neeg siv khoom yooj yim rau re- txheej txheem hlau, yog li txo cov nqi pib. Thiab vim nws zoo heev corrosion kuj, nws txo lub neej voj voog nqi, thiab lwm yam, thaum kawg txo tus nqi tag nrho.
