用白青铜来电镀五金产品比用镍金属还要好,江苏省镇江市公私合营振华五金翻砂抛光厂,在最近试验中已获得成功。白青铜原料配方采用了一公升水为比例、锡酸钠100克、氰化铜16克、氰化钠20克、氰氧化钠7～8克、过氧化氰4两、双养水10公升。药水浓度规定16°,温度60℃。他们曾经用镀镍和白青铜的产品同时侵入鹽水里,在24小时后,镀镍的产品开始生锈,而镀了白青铜的产品的色泽依旧光亮。根据该厂的试验,用白青铜代替镍来电镀五金产品,还可以消除目前镍金属供应紧张的情况,可使成本降低20％。他们在
Plating hardware products with white bronze is even better than using nickel metal. Zhenjiang City, Jiangsu Province, public-private joint venture Zhenhua hardware turning sand polishing plant, has been successful in recent trials. White bronze raw material formula using a liter of water for the ratio of 100 grams of sodium stannate, 16 grams of copper cyanide, 20 grams of sodium cyanide, sodium cyanate 7 to 8 grams, 4 two cyanide, double water 10 liters. Potion concentration 16 °, temperature 60 ℃. They used both nickel-plated and white-bronze products to intrude into the brine at the same time. After 24 hours, the nickel-plated products started to rust, while the white-bronzed products were still shiny. According to the plant’s trial, plating white metal with nickel instead of nickel can also eliminate the current tight supply of nickel metal, which can reduce costs by 20%. They are here
