Because the steel plate will produce oxidation corrosion, it must be added on the surface of the anti-corrosion layer, the general use of anti-corrosion coating is divided into hot dip galvanized Zinc and hot diffuse aluminum zinc alloy A-Zn (aluminum zinc alloy composition is 53%, zinc 43.5% and silicon 1.5%, referred to as 55%A-Zn). Data show that 55% aluminum zinc coating comprehensive anticorrosion ability for the same thickness of zinc 4 times.According to the foreign experience specification, the anticorrosion coating of the base material of general molded steel plate (pit plate) should not be less than hot dip galvanized 350g/m (35) or hot dip aluminum zinc 185 g/m(AZ185)The minimum hot-dip Zinc/Galvanizing specification for cold-rolled section steel and floor slab of building structure is 275 g/ (Z27), and the requirement for coastal exposed parts is 350g/m(235).
The characteristics of aluminium zinc plate:
1 heat reflective:Aluminium zinc steel plate heat reflectivity is very high, is twice the galvanized steel sheet, people often use it to make heat insulation material.
2. Heat resistance:Aluminium zinc alloy steel plate with good heat resistance and can bear the high temperature of 300 degrees Celsius, and the high temperature oxidation resistance of aluminized steel plate is very similar, often used in chimney pipe, oven, illuminator and daylight lamp shade. Corrosion resistance:Aluminum plating zinc corrosion resistance is mainly because the aluminum coil, aluminum protection function. When there is wear and tear of zinc, aluminum and form a layer of dense alumina, to prevent further corrosion of internal corrosion resistance material.
3 economyBecause the density of 55% AL - zinc is smaller than the density of zinc, so in the same weight and thickness of the plating layer of the same case, aluminium zinc steel plate is larger than the area of the plated steel sheet by 3%On.
4. Easy to paint onAluminium zinc plate and excellent adhesion between paint, without pretreatment and weathering process can be painted.Aluminium zinc steel plate gold plated layer coating adhesion is relatively good, so without Weathering such as pretreatment, may also directly in the AD board and the general use coated plateCloth,
5 aluminium zinc steel plate with the silver surface.
6, with galvanized steel plate and aluminium zinc steel plate with similar processing performance and spraying performance.
