Abstract
The present invention belongs to the production field of nickel foam, and particularly relates to a nickel foam production process. The nickel foam production process comprises the steps of base material conductionization, electro-deposition and plating solution purification and heat treatment, wherein the plating solution purification comprises the following steps: pumping a plating solution in a plating tank into at least two connected filter cylinders internally loaded with an active carbon by a circulating pump, and filtering the plating solution by the active carbon and allowing the filtered plating solution to return to the plating tank. On-line filter process achieves on-line impurity process, so as to prolong the service time of the plating solution, improve the electro-deposition production efficiency, reduce the process frequency of the plating solution, increase the yield per unit, reduce the production cost, improve the competitive powder of products, and furthermore lay a solid foundation for products to maintain the market. The quality continuity rate of the products is improved to 98.5% from 95.8%, and the plating solution can be continuously used for 60-300 days.
