New star will show you the types of water-based metal cleaning agents
2015-06-02 956
1. Single metal cleaner由单一的外表活性剂构成的清洗剂，被称为单一水基金属清洗剂。在实践的使用中，单一清洗剂固然也具有必定的清洗功用，但只能用作清洗特别用处的金属工件。由于工业污垢的多样性，从而决议了单一清洗剂简直没有使用在金属清洗的时机。2、复合金属水基清洗剂望文生义，由多种外表活性剂复合而成的清洗剂，称为复合水基金属清洗剂。其任务道理是由多种外表活性剂复配能发生协同感化，

Xinsida interprets the common adverse phenomena of cyanide alkali copper, which needs attention
2015-05-11 1093
1、 Slow deposition speed and poor deep plating ability1.先查看电流密度的巨细2.再看阳极是不是钝化，游离NaCN是不是正常3.溶液是不是被Cr6+污染。二、镀层有针孔1.先看基材外表是不是存在粗糙度较大。2.查看前处理是不是妥当，是不是按要求做到“四无”规范（无油，无锈，无挂灰，无氧化膜）3.Cu低或游离NaCN过高，
