As a leader in domestic high-end coating products, BGHS Special Alloy Technology Group continues to conduct research and development on high corrosion-resistant coating products, and writes the brand of "Zinc has aluminum and good magnesium foot" with its internal technical strength and external beautiful appearance. The story leads the healthy development of domestic high-end coating products.
Since the high-aluminum-zinc-aluminum-magnesium of Dongshan base was successfully off-line on May 27th, a few days ago, the equipment commissioning and optimization of production mode in its new plant in Huangshi lasted several months. Off-line, officially mass production. The high-aluminum-zinc-aluminum-magnesium substrate and special coating will increase the service life of the product to more than 30 years with stronger corrosion resistance and cut protection.
The successful mass production of high-aluminum-zinc-aluminum-magnesium color coating of Huangshi Company marks the addition of a new member of the BGHS high-aluminum-zinc-aluminum-magnesium family, which will further enrich the application of BGHS 1 million tons of color coating in subdivided industries and provide more diversification for users Product solutions.
High aluminum zinc aluminum magnesium product introduction
High-aluminum-zinc-aluminum-magnesium coating: It is the fourth generation product after galvanizing series, galvanizing aluminum series, and aluminum-zinc coating series. The coating of the steel plate is formed by AI (more than 50%)-Zn-Mg alloy with very fine structure. It has high strength corrosion resistance of aluminum and zinc plating. It is a new type of environmentally friendly steel plate with high corrosion resistance, which can effectively improve the color. The corrosion resistance of the coated plate reduces the rate of corrosion expansion under the film and also improves the protection effect of the cut. The aluminum zinc magnesium coating has high corrosion resistance, low friction factor and stability, and also has excellent processing performance.
Planar corrosion resistance
High-aluminum aluminum zinc-magnesium has significantly better plane corrosion resistance than aluminum-zinc plating and hot-dip pure zinc plating.
Under the condition of neutral salt spray test, the time of red aluminum rust of high aluminum, aluminum, zinc and magnesium is longer than that of aluminum-zinc coating with the same coating thickness by more than 50% on average.
Under the condition of cyclic corrosion test, the time of red rust of high aluminum aluminum zinc magnesium is nearly doubled than that of GL coating with the same coating thickness.
Notch corrosion resistance
The corrosion resistance of high aluminum aluminum zinc magnesium is significantly better than that of aluminum zinc coating.
Under the neutral salt spray test conditions, the greater the zinc ratio index, the greater the increase in the corrosion resistance of the high aluminum aluminum zinc magnesium compared to the aluminum zinc coating.
Punch Cup Corrosion Resistance
Under the conditions of neutral salt spray test, the red rust time of the high aluminum aluminum zinc magnesium cup is about twice that of the aluminum zinc coating.
Bending corrosion resistance
Under the condition of neutral salt spray test, the corrosion resistance of high aluminum aluminum zinc magnesium after bending is about twice that of aluminum zinc coating
