我国在铍铜生产中一直使用铬酸——硫酸清洗液作表面清洗,但在清洗过程中,产生的铬离子与氮氧化物,对操作人员、工作环境都带来很大的危害,因此,采用不含铬离子的清洗剂是生产第一线的强烈愿望。上海有色金属研究所与上海压延厂合作,经多方案研究,选定了PS清洗液替代铬酸,应用于铍铜的表面清洗工序,不仅产品质量符合国家标准,而且消除了铬离子对环境的污染。这种清洗剂的组成包括腐蚀剂(H_2SO_4)、辅助剂(加速剂、抛光剂),氧化
China has been using beryllium copper production of chromic acid - sulfuric acid cleaning fluid for surface cleaning, but in the cleaning process, the resulting chromium ions and nitrogen oxides, the operator, the work environment has brought great harm, therefore, The use of non-chromium ion cleaning agent is the production of the first line of a strong desire. Shanghai Institute of Nonferrous Metals and the Shanghai rolling plant cooperation, the multi-program study, selected the PS cleaning solution instead of chromic acid, beryllium copper used in the surface cleaning process, not only product quality in line with national standards, but also eliminates the chromium ions on the environment Pollution. The composition of this cleaning agent includes etchant (H 2 SO 4), auxiliaries (accelerators, polishes), oxidation
