B-Zn添加剂是用于氯化物光亮镀锌的一种新型添加剂,已用于生产达五年之久,经大批量生产验证,B-Zn添加剂具有以下特点:(1)氯化钾型、氯化钠型、氯化铵型等镀锌工艺均可获得光亮的镀锌层;(2)镀液稳定,日常生产维护费用低,在同一镀液内既可挂镀,又可用于滚镀;(3)温度适用范围大,电流效率高,沉积速度快,有较好的深镀能力和分散能力;(4)对高碳钢、铸 B-Zn additive is a new type of additive used in the bright zinc plating of chlorides. It has been used for five years and has been verified by mass production. The B-Zn additive has the following features: (1) Sodium chloride type, ammonium chloride type zinc plating process can get bright galvanized layer; (2) the bath is stable, low cost of daily production and maintenance, both in the same plating bath plating, but also for barrel plating ; (3) large temperature range, high current efficiency, rapid deposition rate, better plating capability and dispersion ability; (4) high carbon steel, cast
