热镀锌：也叫热浸锌和热浸镀锌：是一种有用的金属防腐办法，首要用于各行业的金属结构设备上。是将除锈后的钢件浸入500℃摆布消融的锌液中，使钢构件表面附着锌层，然后起到防腐的意图。
Hot dip galvanized hot-dip galvanized and hot dip galvanized: also called: a useful metal anti-corrosion approach, mainly used for metal structure equipment of various industries on the. The liquid zinc steel immersed in 500 degrees at the mercy of rust after ablation, the steel member is attached to the surface of the zinc layer, then have antiseptic intention.
冷镀锌：即是电镀锌，上锌量少，只要10－50g/m2，即是利用电解效果使金属或其它资料制件的表面附着一层金属膜的技术。形成均匀、细密、结合力杰出的金属层的过程能够起到防止腐蚀，提高耐磨性、导电性、反光性及增进漂亮等效果
Cold galvanizing: that is, zinc plating, the amount of zinc is less, as long as 10 - 50g/m2, that is, the use of electrolytic effect of metal or other materials on the surface of a layer of metal film technology. The process of forming a metal layer is uniform and dense, with great force has the ability to prevent corrosion, improve wear resistance, electrical conductivity, reflective and improves the beautiful effect
热镀锌与冷镀锌的差异：
Difference between hot dip galvanizing and cold galvanizing:
1、防腐蚀性不一样，热镀锌是冷镀锌的几十倍。
1, corrosion resistance is not the same, hot galvanizing is several times the cold galvanizing.
2、工作的办法上不一样：热镀锌是在450－480度熔融的锌液中镀的锌，冷镀是在常温下经过电镀或许别的办法镀的锌。
2, the work is not the same way: hot dip galvanized in 450 - 480 degrees of molten zinc plating, cold plating is at room temperature after plating or other methods of zinc plating.
3、镀锌层厚度不一样，热镀锌厚度远远大于冷镀锌。
3, galvanized layer thickness is not the same, hot galvanized thickness is greater than the cold galvanizing.
4、表面润滑度不一样，冷镀锌表面比热镀锌润滑美观。
4, the surface is not the same degree of lubrication, cold galvanized surface specific zinc lubrication.
5、报价不一样，热镀锌报价高于冷镀锌。
5, the price is not the same, hot galvanized higher than galvanized.
6、冷镀锌能够只镀一面，热镀锌要得全镀。
6, cold galvanized can only be plated on one side, hot galvanized to get full plating.
7、附着力不一样，冷镀锌附着力不如热镀锌。
7, adhesion is not the same, cold galvanized adhesion as hot galvanized.
8、收费标准不一样，热镀锌依照资料的厚度收费，冷镀大多数依照平方米收费。
8, the standard is not the same, hot galvanized in accordance with the thickness of the information collection, the majority of the majority of cold galvanized square meters.
热镀锌技术首要运用规模：工业、建筑、电力设备、化工设备、机械制造、石油、市政设备、农业设备、通信设备、消防设备、铁路、公路交通设备等范畴。
Hot galvanizing technology used in the first scale: industrial, construction, electrical equipment, chemical equipment, machinery manufacturing, petroleum, municipal equipment, agricultural equipment, communication equipment, fire equipment, railway and highway transportation equipment category.
