佛山无花镀锌板0.35-0.5mm薄镀锌板非钝化DX51D+Z60分条平板万庆物资

镀锌板由于涂镀工艺中处理方式不同，表面状态也不同，如普通锌花、细锌花、平整锌花、无锌花以及磷化处理的表面等。切成定尺长度的镀锌板及镀锌卷板不得存在影响使用的缺陷（以下详述），但卷板允许有焊接部位等若干不正常部分。锌花大小由液态锌的成分来控制的同时，采用强制冷却的方法来控制,小锌花产品在锌花开始扩散之前,用小锌花设备进行急冷防止锌液继续扩散,形成小锌花。

Galvanized plate due to the different treatment methods in the coating process, the surface state is also different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower and phosphating treatment surface. The galvanized plate and galvanized coil plate cut into fixed length shall not have defects affecting the use (detailed below), but the coil shall have some abnormal parts such as welding parts. The size of zinc flower is controlled by the composition of liquid zinc, and the forced cooling method is adopted. Before the product of zinc flower begins to spread, the small zinc flower e is used to prevent the zinc liquid from continuing to spread and form a small zinc flower.

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。

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.
