乐从钢铁世界无花镀锌板DX51D+Z60g非钝化轻涂油0.35mm彩基板

随着我国工业化的发展，钢材防腐问题在整个国民经济中具有重要的经济意义。特别是薄钢板生产工序复杂，加工工艺难度大，生产成本高，价值高。同时，又多用于高科技领域及汽车、家电等行业，它和广大人民的生活息息相关。由于钢板较薄，较容易遭受大气腐蚀而报废。长期以来，人们创造了许多防止钢材腐蚀的有效措施， 热镀锌即是其中一种历史较悠久的防腐方法。因为热镀锌具有生产、方法易行、阴极保护、镀层牢固、外观漂亮等优点，普遍被应用到许多领域。

With the development of China's industrialization, the steel anticorrosion problem is of great economic significance in the whole national economy. Especially the production process of thin steel plate is complex, the processing process is difficult, high production cost, high value. At the same time, it is mostly used in high-tech fields and automobile, home appliances and other industries, which is closely related to the lives of the people. Because the steel plate is relatively thin, it is the most vulnerable to suffer from atmospheric corrosion and scrap. For a long time, people have created many effective measures to prevent the corrosion of steel, and hot-dip galvanizing is one of the oldest anti-corrosion methods. Because hot-dip galvanizing has the advantages of low production cost, easy method, cathodic protection, firm coating, and beautiful appearance, it is widely used in many fields.

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.

合理的选材不仅可以满足使用要求，而且可以较大限度的降。如果选材不当，其结果可能是材料性能**过了使用要求，造成不必要的浪费，也可能是达不到使用要求，造成 降级或无法使用。因此，客户应高度重视合理选材的重要性，必要时应向佛山万庆专业业务员咨询。

Reasonable material selection can not only meet the use requirements, but also minimize the cost. If the material is not selected properly, the result may be that the material performance exceeds the use requirements, resulting in unnecessary waste, or may also fail to meet the use requirements, resulting in degradation or unable to use. Therefore, customers should attach great importance to the importance of reasonable material selection, if necessary, should consult Foshan Wanqing professional salesman.
