现货批发55%镀铝锌板

镀铝锌板是一种合金的结构,它的主要成分有铝,大概占据了55%,还有锌是43.4%,另外还加入了1.6%的硅,再经过高温后形成的一种板材。它的耐腐蚀性能非常的突出,耐久性能也是非常优异的。
Aluminized zinc plate is an alloy structure, its main component is aluminum, about 55%, and zinc is 43.4%, in addition to 1.6% silicon, and then after high temperature to form a plate. Its corrosion resistance is very outstanding, and the durability is also very excellent.
锌的化学性质活泼,在常温下的空气中,表面生成一层薄而致密的碱式碳酸锌膜,可阻止进一步氧化,而铝在空气中,可形成不能溶解的氧化物层,在其中起屏障保护功能;试验在同等厚度、镀层、表面处理方式的热镀锌钢板与镀铝锌钢板的前提下。镀铝锌比热镀锌有优异的耐腐蚀性因为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,镀铝锌钢板比镀锌钢板的面积大3%以上。镀铝锌由于力学性能的增加,内层基材表面镀层密度较好,含锰量相对高,因此镀铝锌在普通焊接条件下无法焊接,只能通过铆钉等其它方连接。在焊接方面热镀锌钢板表现较好。普通热镀锌产品通常使用温度不超过230度,250度是会变色,而镀铝锌板可在315度的环境下长期使用不变色。
The chemical nature of zinc is active, in air at room temperature, a thin and dense alkaline zinc carbonate film is formed on the surface, which can prevent further oxidation, while aluminum can form insoluble oxide layer in air, in which is the barrier protection function; under the premise of hot-dip galvanized steel plate and aluminum zinc steel plate of the same thickness, plating and surface treatment. Aluminized zinc has excellent corrosion resistance over hot dip galvanizing. Because the density of 55%AL-Zn is less than that of Zn, the area of aluminum-plated zinc sheet is more than 3% larger with the same weight and the same gold plating thickness. Due to the increase of mechanical properties of aluminized zinc, the surface coating density of the inner substrate is good, and the manganese content is relatively high, so the aluminized zinc can not be welded under ordinary welding conditions, and can only be connected by rivets and other parties. In welding, hot-dip galvanized steel plate performance is better. Ordinary hot-dip galvanized products usually use the temperature is not more than 230 degrees, 250 degrees will change color, and aluminized zinc plate can be used in 315 degrees of environment for a long time does not change color.
镀铝锌板的热反应性能很高,是镀锌钢板的两倍以上,所以它可以作为隔热的材料。另外能够承受300多度的高温,能用于烟囱管道或者日光灯罩等等。
Aluminized zinc plate's thermal reaction performance is very high, which is more than twice that of galvanized steel plate, so it can be used as a heat insulation material. In addition, it can withstand a high temperature of more than 300 degrees, which can be used for chimney pipes or fluorescent lampshade and so on.
