Vim li cas Zinc Aluminium Alloy zoo dua Zinc Ntshiab
Zinc- aluminium alloy coatings ua tau zoo dua cov zinc ntshiab hauv ib puag ncig hnyav vim muaj kev sib koom ua ke ntawm ob qho tib si hlau.
1. Txhim kho Corrosion Resistance
Aluminium tsim ib txheej tuab oxide uas ua rau qeeb corrosion propagation.
2. Lower Porosity Txheej
Zn-Al coatings yog denser thiab tsawg ntxeem tau tshaj cov zinc txheej ntshiab.
3. Lub neej ua haujlwm ntev dua
Kev tiv thaiv ncua sij hawm nyob rau hauv marine thiab industrial atmospheres.
4. Zoo dua Adhesion zog
Txhim kho kev sib raug zoo nrog steel substrate txo cov txheej txheem delamination.

Txau txheej txheem Performance
Zn-Al hlau ua tau zoo nyob rau hauv cov tshuaj tsuag arc vim nws tus cwj pwm melting ruaj khov thiab zoo ib yam atomization.
Nws txo cov tshuaj tsuag tsis xws luag xws li porosity, discontinuity, thiab tsis sib xws txheej thickness, kom ntseeg tau cov khaubncaws sab nraud povtseg ntawm steel nto.
Cov txheej txheem kev yuav khoom
Thaum xaiv zinc aluminium alloy hlau, xav txog cov hauv qab no:
- Zn / Al ratio (85/15 los yog 90/10)
- Hlau txoj kab uas hla kam rau ua
- Nto oxidation theem
- Tensile zog stability
- Txheej ib puag ncig (marine lossis hauv av)
- Daim ntawv pov thawj zoo tshaj plaws (ISO / COA)
Kev xaiv qib raug yog qhov tseem ceeb rau kev ua tiav ntev - lub sij hawm tiv thaiv corrosion.
