哈尔滨电机厂采用的锌酸盐无氰镀锌工艺是一项新工艺,能消除因电镀而产生的职业病。其中主要成份是氢氧化钠及三乙醇胺(氢氧化钠的含量为50—90克/升,三乙醇胺的含量范围在30～80克/升)含量范围较宽,找不准恰当的含量,并且电流密度值低。试验中当电流密度达到1安/平方寸时。镀件边缘被烧焦的现象较严重。因此,沉积速度也 Zincate zinc cyanide-free zinc plating process used by Harbin Electric Works is a new process that can eliminate occupational diseases caused by electroplating. The main ingredient is sodium hydroxide and triethanolamine (sodium hydroxide content of 50-90 g / L, triethanolamine content in the range of 30 to 80 g / L) a wide range of content, find out the right content, and Low current density value. When the test current density reached 1 amps / square inch. Plating edge was burned more serious phenomenon. Therefore, the deposition rate is also
