Common production process of nickel foam

As a kind of foam metal, there is a common production process in the production process. In the production process, the polyurethane sponge is made conductive through some special processes, and then the material is obtained by sintering after the deposition is completed by electrodeposition. However, it is worth noting that in the production process, there are three main methods for conducting conductive treatment, including chemical plating, conductive adhesive coating, and vacuum plating.

In the actual production process, the electrodeposition process mainly relies on silver sulfate or sulfamic acid salt, so that the metal nickel is plated on the polyurethane cotton. At the same time, in the production process, according to the current sintering process, the production process mainly uses air to burn off the polyurethane cotton; after completing the above steps, hydrogen is used as a reducing gas for two steps of sintering, so that a single step can be completed. series of production processes.
