镀铝锌光板的优势
1经济
由于55%Al-Zn的密度小于Zn,在相同重量和相同镀金层厚度下,Al-Zn镀层的面积比Zn镀层的面积大3%以上。
2耐热性
普通
热镀锌产品一般使用温度不超过230度,250度时会变色,而热镀锌产品镀铝锌板可在315度下长时间使用而不变色。
3热反射
铝和锌的热反射和光反射能力是镀锌钢板的两倍,反射率大于0.70,优于EPA能源之星规定的0.65。
4机械性能
热镀锌产品镀铝锌钢板的力学性能主要包括屈服强度、抗拉强度和延伸率。150g/m2普通dc51d镀锌钢板的屈服强度为140~300mpa,抗拉强度为200~330,延伸率为13~25。dc51d+az150g/m2铝锌板的屈服强度为230~400mpa,抗拉强度为230~550,延伸率为15~45
1 economy
Because the density of 55% Al Zn is smaller than that of Zn, the area of Al Zn plated steel sheet is more than 3% larger than that of Zn plated steel sheet under the same weight and the same thickness of gold plating layer.
2 heat resistance
Ordinary hot-dip galvanized products are usually used at a temperature of not more than 230 degrees, which will change color at 250 degrees, while aluminized zinc sheet can be used at 315 degrees for a long time without changing color.
3 heat
reflection
The ability of aluminum and zinc to reflect heat and light is twice that of galvanized steel sheet, and the reflectivity is greater than 0.70, which is better than 0.65 specified by EPA energy star.
4 mechanical properties
The mechanical properties of Al Zn plated steel sheet mainly include yield strength, tensile strength and elongation. The yield strength, tensile strength and elongation of ordinary dc51d galvanized steel sheet with 150g / m2 are 140-300mpa, 200-330 and
13-25 respectively. The yield strength, tensile strength and elongation rail of dc51d + AZ 150 g / m2 Al Zn plate are 230-400 MPa, 230-550 and 15-45 respectively
