一、前言电镀锌、热浸镀锌是镀锌薄壁钢管镀锌层所采用的主要工艺方法。电镀锌是电化学过程,通过电镀在钢管表面沉积出锌镀层。热浸镀锌是将钢管放在熔融的锌锅中(460°～480°c),经一定时间取出,通过两种金属熔融状态下互相溶解,在钢管表面形成锌镀层。这两种工艺,方法不同,原理也各不相同。热浸镀锌由于能获得较厚的镀层(0.06～0.10毫米),故普
First, the preface Electro-galvanized, hot-dip galvanized galvanized thin-walled steel galvanized layer is the main process used. Electro-galvanizing is an electrochemical process that deposits a layer of zinc on the surface of a steel tube by electroplating. Hot-dip galvanized steel tube is placed in a molten zinc pot (460 ° ~ 480 ° c), after a certain period of time removed through two molten state dissolved in each other to form a zinc coating on the pipe surface. The two processes, methods are different, the principle is also different. Hot dip galvanized can get a thicker coating (0.06 ~ 0.10 mm), so Cape
