前言目前国内外锌电解所使用的阳极,均为铅银(1％银)合金板。此种阳极在生产上存在许多缺点:第一易溶解,既消耗大量阳极材料,又严重影响产品锌的质量;第二机械强度差,尤其是经使用一阶段后,容易出现阴阳极在电解槽中短路现象,降低电流效率;第三产生的阳极泥量大,影响导电能力,增加了工人的劳动强度。为改进这些不足之处,近几年来,国外开始有人研究以钛为基体,涂二氧化锰作锌电解的阳极。这种阳极的理想状态,可消除铅银阳极的缺点,显出它许多宝贵性质:完全不溶,提高了产品锌质量;机械强度高,
Preface At present, the anode used in zinc electrolysis at home and abroad are lead silver (1% silver) alloy plate. Such anodes have many shortcomings in production: the first one is easy to dissolve, which not only consumes a large amount of anode material, but also seriously affects the quality of the product zinc; the second one is poor in mechanical strength, especially after one stage is used, Short circuit phenomenon, reducing the current efficiency; the third generation of anode mud volume, affecting the conductive capacity, increasing the labor intensity of workers. In order to improve these shortcomings, in recent years, some people started to study titanium as the substrate, coated manganese dioxide anode for zinc electrolysis. The ideal state of this anode eliminates the shortcomings of the lead silver anode, showing many of its valuable properties: completely insoluble, improving the zinc quality of the product; high mechanical strength,
