冷镀锌也叫电镀锌,济南镀锌管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 electro galvanized, galvanized pipe in Ji'nan is the use of electrolytic equipment will work after degreasing, pickling solution into the composition of the zinc salt in the anode and connected electrolytic equipment; cathode zinc plate placed in the workpiece in the electrolysis equipment connected across the power supply is switched on, the current from the anode to the cathode of the directional movement will, depositing a layer of zinc on the workpiece.
热镀锌是将工件除油,酸洗,浸药,烘干后浸入溶化的锌液里一定时间,提出来即可。
Hot dip galvanizing is to remove the oil, acid washing, dipping, soaked in the dissolved zinc solution after drying for a certain time, it can be put out.

济南镀锌管

电镀锌外表比较光滑,明亮,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。济南镀锌管在复杂工件的角棱部位容易产生"电烧"而成灰暗,该部位锌层较厚,在阴角部位易形成电流死角而产生欠电流灰暗区,该区域 锌层较薄,工件整体无锌瘤,结块等现象。
The galvanizing surface is smooth and bright, and the electroplating layer with color passivation technology is also yellow green, and it is seven color. The electroplating layer of white passivation process is green white or white, and the coating of white passivation process is slightly colourful with sunlight at a certain angle. The galvanized pipe of Ji'nan is prone to "electric burn" in the corners of complex workpieces, which is dark. The zinc layer in this part is thicker. It is easy to form a current dead angle in the negative corners, resulting in an undercurrent dark area. The zinc layer in the area is thin, and the workpiece has no zinc lump and lump.
在热镀锌钢管的一端有锌针或少许瘤挂,内外都有完整的镀锌层,外观没有冷镀锌光滑,冷镀锌镀层有光亮,与太阳成一定角度下这种光亮成七彩,冷镀钢管孔内只有在两端有少许锌层,再往里没有镀锌层,冷镀锌国内钢管两端一样光滑,当然没有锌瘤产生,外表没有执行标准。
At the end of galvanized steel with zinc needle or a tumor, both inside and outside the galvanized layer intact, no appearance of cold galvanized cold galvanized coating is smooth and bright, with a certain angle under the bright sun and into a colorful, cold plated steel tube hole only at both ends with a little zinc layer, inside no galvanized layer the two ends of the steel pipe, cold galvanized as smooth, no zinc tumor, no standard appearance.
