氨基磺酸镍镀液的配比及制作工艺介绍
来源:http://www.jnjrh.com 日期:2019-07-31 发布人:admin
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。
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.
氨基磺酸镍电镀工艺:
Nickel sulfamate plating process:
将耐酸耐温的槽用去离子水充分清洗,确保无氯离子及其他杂质后,加入三分之一的去离子水,用钛或聚四氟乙烯加热器加热到60℃后,加入所需量的氨基磺酸镍、六水氯化镍、硼酸、湿润剂和添加剂。然后加去离子水至所需液位,用无油压缩空气充分搅拌后,以波浪形的阴极在0.5A/dm2下电解到凹处由黑色变浅色为止,后进行电镀。
The acid-resistant and temperature-resistant tank is fully cleaned with deionized water to ensure that there are no chloride ions and other impurities. A third of the deionized water is added. After heated to 60 ~C with titanium or polytetrafluoroethylene heater, the required amount of nickel sulfamate, nickel chloride hexahydrate, boric acid, wetting agent and additives are added. Then, deionized water is added to the required liquid level. After fully stirring with oil-free compressed air, the wavy cathode is electrolyzed at 0.5A/dm2 until the concave is changed from black to light. Finally, electroplating is carried out.
注意:氨基磺酸镍溶液中不可以加硫酸镍,只可加入碱式碳酸镍、氯化镍、氨基磺酸镍。
Note: Nickel sulfate should not be added to nickel sulfate solution, but basic nickel carbonate, nickel chloride and nickel sulfamate can only be added.
氨基磺酸镍对人的危害:
The harm of nickel sulfamate to human beings:
氨基磺酸通过吸入可能造成敏化作用,通过皮肤接触可能造成敏化作用,在皮肤上面:可能引起发炎;在眼睛上面:可能引起发炎。
Aminosulfonic acid may cause sensitization by inhalation, sensitization by skin contact, on the skin: may cause inflammation; on the eyes: may cause inflammation.
