镀锌镀锌铁铁皮
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，最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最悠久的防腐方法。因为热镀锌具有生产成本低、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.
镀锌板是钢制板材表面通过镀锌工艺处理后表面镀上一层锌的板材，锌比较活泼，常温下会与空气中的氧气快速反应生成一层碱式碳酸锌膜，这层膜会阻止锌继续与空气发生反应，从而保护锌层免受空气的侵蚀，也就保证了锌层下面的钢材不会受到空气的腐蚀，出现起斑生锈的现象。
Galvanized sheet is steel sheet surface by galvanizing process surface plating on a layer of zinc plate, zinc, more lively, at room temperature with the oxygen in the air to generate a layer of alkaline zinc carbonate film, the film will prevent zinc continue to react with air, to protect the zinc layer from air erosion, also ensure the zinc layer under the steel will not be the air corrosion of, spot rust phenomenon.
合理的选材不仅可以满足使用要求，而且可以最大限度的降低成本。如果选材不当，其结果可能是材料性能超过了使用要求，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.
