一。热反射比：
镀铝锌钢板具有较高的热反射比，是镀锌钢板的两倍。人们经常把它用作隔热材料。
2。耐热性：
铝锌合金钢板具有良好的耐热性，能承受300摄氏度以上的高温。这与镀铝钢板的高温抗氧化性能非常相似。它常用于烟囱、烤箱、照明器和荧光灯罩。耐腐蚀性：
镀铝锌钢卷的耐蚀性主要取决于铝和铝的保护作用。当锌磨损时，铝形成一层致密的氧化铝层，从而防止内部耐腐蚀材料的进一步腐蚀。
三。经济性：
由于55%Al-Zn的密度小于Zn，在相同的镀金层重量和厚度下，Al-Zn钢板的面积比镀锌钢板大3%以上。
四。容易上漆
镀铝锌板与油漆具有良好的附着力，无需预处理和风化处理即可涂漆。
镀金铝锌钢板的镀层附着力比较好，因此也可以直接在广告牌和一般用途的板材上涂布，而不需要经过风化等预处理。
5个。镀铝锌钢板有一个华丽的银白色表面。
6。镀铝锌钢板和镀锌钢板具有相似的加工性能和喷涂性能。
Characteristics of aluminum zinc plate
1. Thermal reflectance:
Aluminized zinc steel plate has a high thermal reflectance, which is twice that of galvanized steel plate. People often use it as heat insulation material.
2. Heat resistance:
Aluminum zinc alloy steel plate has
good heat resistance, which can withstand the high temperature of more than 300 degrees Celsius. It is very similar to the high temperature oxidation resistance of aluminum coated steel plate. It is often used in chimney tubes, ovens, illuminators and
fluorescent lampshades. Corrosion resistance:
The corrosion resistance of aluminum coated zinc steel coil is mainly due to the protection function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of alumina, which prevents
further corrosion of the corrosion-resistant material inside.
3. Economy:
Because the density of 55% Al Zn is smaller than that of Zn, the area of Al Zn steel plate is more than 3% larger than that of galvanized steel plate under the same
weight and thickness of gold plating layer.
4. easy to paint
There is excellent adhesion between the aluminized zinc plate and the paint, which can be painted without pretreatment and weathering treatment.
The coating adhesion of the
gold-plated aluminum zinc steel plate is relatively good, so it can also be directly coated on the advertising board and general use board without pretreatment such as weathering.
5. The aluminum zinc plated steel plate has a gorgeous silver white
surface.
6. Aluminized zinc steel plate and galvanized steel plate have similar processing performance and spraying performance.
