目前，市场上的镀锌板主要有热镀锌和电镀锌两种类型。从经济成本的角度来考虑.由于热镀锌板工艺在不断地完善和提高，大多经济型汽车主要采用热镀锌板;而由于电镀锌板材料具有良好的加工性，中、高端汽车还是主要采用电镀锌板.特别是由于一些车型和配件的限制，须采用电镀锌板。

At present, the galvanized plate on the market is mainly hot galvanized and galvanized two types.Consider it from the perspective of economic cost. Due to the continuous improvement and improvement, most economical cars mainly use hot galvanized plate; and due to the good processing of electric galvanized plate material, middle and high-end cars mainly use electric galvanized plate. In particular, due to the limitations of some models and accessories, electric galvanized plates are required.

电镀锌板，又称电解板，俗称冷镀锌板，它利用电解方法，以锌锭作阳极，钢带作阴极，锌原子失去电子后变成离子态并溶解到电解液中，锌离子从带钢上得到电子被还原成锌原子沉积到带钢的表面上，形成一层均匀、致密、结合良好的金属或合金沉积层，这样就制成了电镀锌板。

Electrogalvanized plate, also known as electrolytic plate, commonly known as cold galvanized plate, it uses electrolysis method, zinc ingot as anode, steel belt as cathode, zinc atoms lose electrons and dissolved into the electrolyte, zinc ions from the strip electron is reduced to zinc atoms deposited on the surface of the steel, forming a uniform, dense, well combined metal or alloy deposit layer, thus making the electrogalvanized plate.

电镀锌板是以冷硬板为原料，不经过退火工艺直接冷板完成镀锌工艺，其成品基本保持了与冷硬板相同的机械加工性能，强度大于热镀锌板，但塑性相对较差，不利于冲压成型。

Electrogalvanized plate is cold hard plate as raw material, which completes the galvanization process without annealing process. The finished product basically maintains the same mechanical processing performance as the cold hard plate, and the strength is greater than the hot galvanized plate, but the plasticity is relatively poor, which is not conducive to stamping forming.

随着我国汽车行业的迅猛发展。人们对汽车车身的耐蚀性的要求越来越高。其中电镀锌板作为汽车用产品，外观颜色呈银白色，且镀层厚度分布均匀，可观性强;相对于镀锌前的原钢板来说，电镀锌后的钢板不仅具有良好的耐腐蚀性，而且原板的加工性能和力学性能不会因为镀锌层而受到影响。

With the rapid development of China's automobile industry.People's car body corrosion resistance is increasingly demanding.The electrogalvanized plate, as automobile products, is silver-white, and the coating thickness is evenly distributed and highly considerable. Compared with the original steel plate before galvanizing, it not only has good corrosion resistance, but also the processing performance and mechanical properties of the original plate will not be affected by the galvanizing layer.

电镀锌板的表面质量优异，涂层分布均匀性也好，但电镀工艺较复杂，加工成本相对较高，环保压力也比热镀锌大很多。

The surface of the electric galvanized plate has excellent quality and uniform coating distribution, but the plating process is more complex, the processing cost is relatively high, and the environmental protection pressure is also much greater than the hot galvanization.
