在电镀生产中,随着槽液温度、酸度、镀件面积和形状的改变,镀槽电流需要随之而变,使诸因素与电流密度协调在最佳范围,以保证高质量的电镀产品。镀件入铬槽时,对其施加短时大电流冲击,可增加镀层晶核数量,改善产品质量。镀亮镍时光亮剂作用很大,含量不易分析,但其消耗与用电量成正比,只要求出镀镍用电量,就可决定光亮剂的添加量。在电镀自行车零件的环形自动线上有81个镀件工位。自动线工位运行分出槽和入槽两个动作。镀亮镍槽有12个工位,镀铬槽有5个工位,分别由3台和4台可控硅整流器供电。在自动线上要镀10种工件,因面积、形状各异,需不同的电流。为了计算所需电流,把各种工件编成代号,对应于各自的电流计算系数k。存于计算机内k
In electroplating production, as bath temperature, acidity, plating area and shape changes, plating bath current needs to be changed, so that the various factors and current density in the best range to ensure high quality plating products. Plated into chrome groove, its short-term high current impact, can increase the number of coated nuclei, improve product quality. Bright nickel plating bright brightener role, the content is not easy to analyze, but its consumption is proportional to the amount of electricity, as long as the demand for nickel-plated power, you can decide the amount of brightener added. There are 81 plating stations on the circular automatic line of plated bicycle parts. Automatic line station run out of slot and into the slot two actions. Galvanized nickel tank has 12 stations, chrome tank has 5 stations, respectively, by 3 and 4 SCR power supply. In the automatic line to be plated 10 kinds of workpieces, due to the area, shape, need different current. In order to calculate the required current, a variety of work-piece code, corresponding to the respective current calculation coefficient k. Stored in the computer k
