1.工艺的区别:

1. the difference between processes:

热镀锌是将工件除油、酸洗、浸药、烘干后浸入溶化的锌液里必定时间,提出来即可。

Hot-dip galvanizing is a necessary time to remove oil, pickle, dip medicine, and immerse the workpiece in the dissolved zinc solution after drying.

冷镀锌也叫电镀锌,是使用电解设备将工件通过除油、酸洗后放入成分为锌盐的溶液中,并衔接电解设备的负极;在工件的对面放置锌板衔接在电解设备的正极 ,接通电源,使用电流从正极向负极的定向移动,就会在工件上堆积一层锌。

Cold galvanizing, also known as galvanizing, is the use of electrolytic equipment to remove oil and pickle the workpiece into the solution of zinc salts, and connect the negative electrodes of the electrolytic equipment; on the opposite side of the workpiece, place a zinc plate to connect the positive electrodes of the electrolytic equipment, connect the power supply, and use the current to move from the positive to the negative electrodes in the direction of stacking on the workpiece. Deposit a layer of zinc.

2.外观的区别:

2. the difference between appearance and appearance:

电镀锌表面比较润滑、明亮,选用彩色钝化工艺的电镀层也黄绿色为主色,呈七彩。选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必定视点下略显七彩。镀锌管知识门户网

The surface of electroplated zinc is relatively lubricated and bright. The Color Passivation Process of electroplated zinc is also yellow-green, showing seven colors. The white passivation process is used to make the plating blue-white or green. The plating of the white passivation process is slightly colorful from a certain point of view with sunlight.

在杂乱工件的角棱部位简单发生“电烧”而成暗淡,该部位锌层较厚。在阴角部位易形成电流死角而发生欠电流暗淡区,该区域锌层较薄。工件整体无锌瘤、结块等现象。镀锌管的相关知识

In the corner and edge part of the disordered workpiece, electric firing occurs easily and becomes dim. The zinc layer in this part is thicker. It is easy to form a dead angle of current at the pudendal corner and produce a dark area of undercurrent, where the zinc layer is thinner. There are no zinc nodules and caking on the whole workpiece. Knowledge of galvanized pipe

3.热镀锌外观较电镀锌略微粗糙,呈银白色,外观简单发生工艺水纹和少量滴瘤,尤其是在工件的一端较为明显。但热镀锌的锌层比电镀锌厚几十倍,防腐蚀功能 是电镀锌的几十倍。

3. The appearance of hot-dip galvanizing is slightly rougher than that of galvanizing, and it is silver-white. The appearance of hot-dip galvanizing is simple and the process water marks and a few droplets occur, especially at one end of the workpiece. But the galvanizing layer of hot dip galvanizing is tens of times thicker than that of galvanizing, and its anticorrosion function is tens of times that of galvanizing.
