High quality properties of aluminum plated zinc plate
发布时间:2021-04-06 06:19:20浏览次数:333
The aluminum zinc plating steel plate is composed of aluminum zinc alloy structure, which is solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 ℃ high temperature. The whole structure consists of aluminum iron silicon zinc, forming a compact tetrahedral alloy.
Aluminum plated zinc plate is a new type of steel plate, which is caused by hot dip galvanizing of cold-rolled or hot-rolled steel plate, and its corrosion resistance is gradually replacing galvanized plate widely used in the world.
Aluminum plated zinc plate usually has the following characteristics:
1. super corrosion resistance: the corrosion resistance of galvanized steel plate is 6-8 times of that of ordinary galvanized plate, which can ensure that it will not rust for 20 years.
2. high temperature oxidation resistance: galvanized steel plate will not change color or deformation in the high temperature environment of 315 ℃ for a long time.
3. high thermal reflectance: the thermal reflectance of galvanized steel plate is higher than 75%, about twice of that of galvanized plate. It can be used as roof and panel without paint to achieve energy saving effect. It can meet stamping, shearing, bending and other processing.
4. beautiful appearance: silver white snowflake pattern, beautiful and beautiful, can be used directly without painting.
5. surface spraying: galvanized steel plate is a good base material for paint coating. The composite coating of alloy and organic matter can provide more efficient protection and prevent corrosion.
6. more use area: the proportion of aluminum plated zinc plate coating (3.75g/m3) is much smaller than that of zinc (7.15g/m3). Therefore, in the case of the same thickness of steel substrate and coating, the per ton of aluminum plated zinc plate is much more than that of galvanized steel plate, which will give users more benefits. Az150 is equivalent to: 1.1050 tons of 0.3mm thick galvanized steel plate (1035 tons 0.5mm thick galvanized steel plate) and 0.7mm thick galvanized steel plate (1025 tons).
7. widely used: it can be used in roof, wall, garage, sound insulation wall, pipe and combined house of building, muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc, The refrigerator back plate, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, led back light source, electrical cabinet, etc. of household appliances, farm pig house, chicken house, granary, greenhouse pipe, etc., other such as heat insulation cover, heat exchanger, dryer, water heater, etc.
