What are the characteristics of aluminized zinc with heat insulation
The surface of aluminized zinc steel plate is unique smooth, flat and gorgeous star flowers, the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of aluminized zinc plate can reach 25A, good heat resistance, can be used for high temperature environment of 315℃; The coating has good adhesion to the paint film, and has good processing performance. It can be pressed, shearing, welding, etc. The surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon by weight ratio. The production process of aluminized zinc steel plate is similar to that of galvanized steel plate and aluminized plate. It is a continuous melting plating process. 55% aluminum-zinc alloy coated aluminum-zinc steel plate has superior corrosion resistance when exposed to the same environment on both sides compared to galvanized steel plate of the same thickness. 55% aluminum-zinc alloy coating aluminum-zinc steel plate not only has good corrosion resistance, color coating products have excellent adhesion and flexibility.
Characteristics of aluminized zinc
1. Heat reflectivity:
Aluminized zinc steel has a high thermal reflectivity, twice that of galvanized steel, and is often used as a heat-insulating material.
2. Heat resistance:
Aluminum zinc alloy steel plate has good heat resistance, can withstand high temperatures of more than 300 degrees Celsius, similar to the high temperature oxidation resistance of aluminum plated steel plate, often used in chimney pipes, ovens, illuminators and solar lampshades. Corrosion resistance:
The corrosion resistance of aluminized zinc steel coil is mainly due to aluminum and its protective function. When the zinc is worn away, the aluminum forms a dense layer of alumina that prevents the corrosion resistant material from further eroding the interior.
3. Economy:
Because the density of 55% Al-Zn is smaller than that of Zn, the area of the aluminum-zinc plate is more than 3% larger than that of the plate under the same weight and the same thickness of the gilt layer.
4. Easy to paint on
The aluminized zinc plate has excellent adhesion to the paint and can be painted without pretreatment and weathering treatment.
The coating of the gilt layer of aluminized zinc steel plate has excellent adhesion, so it can also be coated directly on advertising boards and general boards without pre-treatment such as Weathering.
5. The aluminized zinc steel plate has a gorgeous silvery white surface.
6. Aluminized zinc steel plate and galvanized steel plate have similar processing performance and spraying performance.
