用电镀锌板为基板，涂上有机涂料烘烤所得的产品为电镀锌彩涂板，由于电镀锌板的锌层薄，通常含锌量为20/20g/m2，因此该产品不适合使用在室外制作墙、屋顶等。但因具有美丽的外观和优良的加工性能，因此主要可用于家电、音响、钢家 具、室内装璜等。从防腐机理的角度看，锌、铝在多数大气环境下具有较高的稳定性，利用它作为钢铁基体的防护性涂(镀)层是普遍公认的有效经济的方法，其应用历史已达一百多年。锌在腐蚀环境介质中会形成一层薄且致密的附着性很强的腐蚀产物(氧化锌，氢氧化锌，碱性盐：Zn(OH)2和ZnCl2或ZnCO3)。这些产物覆盖在其表面对周围环境介质起着屏蔽作用，从而阻止进一步腐蚀。

Electric galvanized board is the substrate, and the product obtained by baking with organic coating is electrogalvanized color coated board. Because the zinc layer of galvanized board is thin, the zinc content is usually 20 / 20g / m2, so this product is not suitable for use in outdoor production walls, roof, etc. But because of the beautiful appearance and excellent processing performance, so mainly can be used for home appliances, audio, steel furniture, indoor decoration, etc. From the perspective of anti-corrosion mechanism, zinc and aluminum have high stability in most atmospheric environments. It is generally recognized as the protective coating (plating) layer of iron and steel matrix, and its application history has reached more than one hundred years. Zinc in a corrosive environmental medium forms a thin and dense layer of highly attached corrosion products (zinc oxide, zinc hydroxide, alkaline salt: Zn (OH) 2 and ZnCl2 or ZnCO3). These products cover their surfaces with a shielding effect against the surrounding ambient media, thus preventing further corrosion.

此外，锌的电极电位较铁为负，属于阳极性镀层，它具有牺牲自身的保护作用。镀锌层在大气环境中的腐蚀尽管随气候类型的变化发生很大变化(一般在海洋性气候中很严重)，然而在相同的环境条件下，其寿命正比于镀锌层的附着量。美国ASTM发表在《金属手册》中

的结果可见欲延长其寿命，可用增加镀锌层厚度的方法来实现。

In addition, the electrode potential of zinc is more negative than iron, which belongs to the anodic coating, which has the protective effect of sacrificing itself. Although the corrosion of galvanized layer in the atmospheric environment changes greatly with the climate type (generally severe in the Marine climate), its life is proportional to the amount of galvanized layer attachment under the same environmental conditions. ASTM is published in the Metal Manual The results can be seen to extend its life, can be used to increase the thickness of the galvanized layer to achieve.
