镀铝锌钢板 | | | | | | | | | | | | | | | | | | | | | | | | | | | |
镀铝锌钢板是日常生活中经常应用到的一种重要的合金材料。镀铝锌钢板是铝锌合金结构组成,由55%铝、43.5%锌与1.5%硅在600℃高温下凝固而组成,其整个结构由铝-铁-硅-锌,形成致密的四元结晶体的一种合金。 | | | |
镀铝锌板特性 | | | | | | | | | | | | | | | | | | | | | | | | | | | |
镀铝锌钢板具有不少优良的特性:强的耐腐蚀性,是纯镀锌板的3倍;表面有漂亮的锌花,可以作为建筑屋外板使用。 | | | | | | | | | | | | | | | |
耐腐蚀性: | | | | | | | | | | | | | | | | | | | | | | | | | | | |
“镀铝锌钢卷”的耐腐蚀性主要是因为铝,铝的保护功能。当锌受到磨损时,铝便形成一层致密的氧化铝,阻止耐腐蚀性物质进一步的腐蚀内部。 | | | | | | | | | | | | |
耐热性: | | | | | | | | | | | | | | | | | | | | | | | | | | | |
铝锌合金钢板具有良好的耐热性,可以承受300多摄氏度的高温,与镀铝钢板的抗高温化性很类似,经常应用于烟囱管,烤箱、照明器器和日光灯罩。 | | | | | | | | | | | |
热反射性: | | | | | | | | | | | | | | | | | | | | | | | | | | | |
镀铝锌钢板的热反射率很高,是镀锌钢板的两倍,人们经常用它来作隔热的材料。 | | | | | | | | | | | | | | | | | | | |
经济性: | | | | | | | | | | | | | | | | | | | | | | | | | | | |
因为55%AL-Zn的密度比Zn的密度小,所以在重量相同和镀金层厚度相同的情况下,镀铝锌钢板比镀钢板的面积大3%以上。 | | | | | | | | | | | | | | |
镀铝锌板的应用 | | | | | | | | | | | | | | | | | | | | | | | | | | |
用途 | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
镀铝锌产品的主要用途为两个方面,一为电器开关柜用其它电器设备用做外壳及箱体;二为钢结构建筑屋面用镀铝锌,因其有很好的防腐、防蚀性能,很多工业污染重的地区环境把镀铝锌彩板,或镀铝锌耐指纹光板直接用在墙面或是屋面上。 |
