氨基磺酸镍是使用氨基磺酸配置出来的吗?
来源:http://www.jnjrh.com 日期:2019-09-17 发布人:admin
用途: 氨基磺酸镍主要用于精密电镀,它的优点是镀层的内应力低,沉积速度快。
Usage: Nickel sulfamate is mainly used for precision electroplating. Its advantages are low internal stress and fast deposition speed.
氨基磺酸镍配方:
Nickel sulfamate formulation:
氨基磺酸镍 300-450g/l
Nickel sulfamate 300-450g/l
氯化镍:2-15g/l
Nickel chloride: 2-15g/l
硼酸:30-45g/l
Boric acid: 30-45g/l
PH值:3.5-4.5
PH value: 3.5-4.5
温度:40-60度
Temperature: 40-60 degrees
阴极电流密度:2-5安/平方分米
Cathode current density: 2-5A/Square decimeter
溶液配置方法:
Solution configuration method:
1、镀槽中加入2/3纯水,加温到60度,将氨基磺酸镍在搅拌状态下加入(可手工搅拌也可用无油压缩空气搅拌),直到完全溶解为止。
1. Add 2/3 pure water to the plating bath and heat it up to 60 degrees. Add nickel aminosulfonate under stirring (manual stirring or oil-free compressed air stirring) until it dissolves completely.
2、将氯化镍在另外槽中溶解好(纯水不要太多,够溶解就好),方法同上。
2. Dissolve nickel chloride in another tank (not too much pure water, just enough to dissolve). The method is the same as above.
3、在另外容器中加入纯水(一公斤硼酸用六升纯水),加温到70度,在搅拌状态下将硼酸倒入,直到完全溶解为止。
氨基磺酸
3. Add pure water to another container (six liters of pure water for one kilogram of boric acid). Warm it to 70 degrees. Pour boric acid in a stirring state until it dissolves completely.
4、将3溶液在搅拌状态下加入1中。
4. Add 3 solution to 1 under stirring condition.
5、将2溶液在搅拌状态下加入1中。
5. Add 2 solution to 1 under stirring condition.
6、将液面补加到规定液位。
6. Adding the liquid level to the prescribed level.
7、按每升溶液3-5克在搅拌下加入粉末状活性炭,连续搅拌2-4小时,再静置10小时以上。
7. Add powdered activated carbon 3-5 grams per liter of solution under stirring, stirring continuously for 2-4 hours, then stationary for more than 10 hours.
8、将静置后的干净溶液倒入别槽中,将活性炭沉淀清理干净,再将溶液倒回槽中。
8. Pour the static clean solution into the separate tank, clean up the activated carbon precipitation, and then pour the solution back into the tank.
9、槽液连续过滤4小时以上(滤心孔径小于5微米)。
9. The tank liquid is filtered continuously for more than 4 hours (the pore size of the filter core is less than 5 microns).
10、将溶液搅拌均匀后测试PH,用碱式碳酸镍或硫酸将PH调到规定范围。
10. Test PH after stirring the solution evenly, and adjust PH to the prescribed range with basic nickel carbonate or sulfuric acid.
11、进行试镀,试镀件正常就可以进行电镀了。
11. Trial plating, the normal sample can be plated.
12、用瓦楞板电解10小时以上(电流密度0.3-0.8安培每平方分米),直到地区不黑为止。
12. Electrolysis with corrugated boards for more than 10 hours (current density 0.3-0.8 amperes per square decimeter) until the area is not dark.
