电镀行业清洁生产审核中的物料平衡

摘要

The material balance diagrams for surface treatment processes such as electroplating, hot-dip galvanizing, phosphating, electrophoresis, pickling, and anodization were summarized based on years of practice in cleaner production audit. The method for establishing material balance was introduced with zinc electroplating as example. How to propose a cleaner production scheme through material balance analysis was explained by taking a chromium electroplating bath in a plant as an example.%根据多年的清洁生产审核实践,总结了电镀、热浸镀、磷化、电泳、酸洗、阳极氧化等表面处理工艺的物料平衡图.以电镀锌为例,介绍了建立物料平衡的操作方法.以某厂的镀铬槽为例,通过实际计算,讲解了如何根据物料平衡分析来提出清洁生产方案.
