冷镀锌也叫电镀锌，是利用电解设备将工件经过除油、酸洗后放入成分为锌盐的溶液中，并连接电解设备的负极；在工件的对面放置锌板连接在电解设备的正极，接通电源，利用电流从正极向负极的定向移动，就会在工件上沉积一层锌。

Cold galvanizing, also called galvanizing, is the use of electrolytic equipment to put the workpiece after oil removal, pickling into the zinc salt solution, and connect the negative electrode of the electrolytic equipment; zinc plate opposite the workpiece connected to the positive electrode of the electrolytic equipment, on the power supply, using the current from the positive electrode to the negative electrode, will be a layer of zinc will be deposited on the workpiece.

冷镀锌利用化学原理将锌合金分离成锌离子，附着在钢铁表面，一般锌层薄，钢铁在一般环境下很容易锈蚀。一般冷镀锌用于各种钢制品和构筑物的防腐，冷镀锌的镀锌量很少，每平方米只有10－50g。

Cold plating galvanizing uses the chemical principle to separate the zinc alloy into zinc ions, attached to the surface of iron and steel, the general zinc layer is thin, iron and steel is easy to rust in the general environment.Generally cold galvanizing is used for corrosion prevention of various steel products and structures, cold galvanizing amount is very small, only 10-50g per square meter.

冷镀锌外表比较光滑、明亮、均匀、平整，采用彩色钝化工艺的电镀层也黄绿色为主色，呈七彩。采用白色钝化工艺的电镀层呈青白色或白色呈绿光，白色钝化工艺的镀层与阳光呈一定角度下略显七彩。冷镀钢钢管内只有两端有少许锌层，再往里没有镀锌层，冷镀锌钢管两端一样光滑，绝对没有锌瘤产生，且钢管外表没有执行标准。

Cold-dip galvanized appearance is relatively smooth, bright, uniform, smooth, the use of color passivation process of electroplating layer is also yellow-green as the main color, is colorful.The electroplating layer of white passivation process is green white or white green light, and the plating layer of white passivation process is slightly colorful at a certain Angle.Cold coated steel pipe only a few ends of the zinc layer, and then there is no galvanized layer, cold ends of the galvanized steel pipe as smooth, absolutely no zinc tumor, and the appearance of the steel pipe does not implement the standard.

小编建议各位新老客户在选择镀锌钢板时要以质量为主，选择质优价美的镀锌钢板，钢板的选择对于建筑工程的质量和安全有极大的影响，选择一间靠谱的钢材经销商，比如佛山市万庆物资有限公司，是一家集钢材销售的大型综合型企业，为国内钢材采购商，提供集采购、销售、信息于一体化服务。

Small make up suggest you new and old customers when choosing galvanized steel plate is given priority to with quality, choose quality price beautiful galvanized steel plate, steel plate choice has great influence on the quality and safety of construction engineering, choose a reliable steel dealers, such as Foshan Wanqing materials co., LTD., is a large comprehensive enterprise of steel sales, for domestic steel buyers, provide procurement, sales, information in the integration of services.
