Product Description:

Nickel foam is a sound-absorbing material with excellent performance, which has a high sound absorption coefficient at high frequencies; the sound absorption performance at low frequencies can be improved through the design of the sound-absorbing structure. Nickel foam is also one of the best electrode materials for the manufacture of cadmium-nickel batteries and hydrogen-nickel batteries.

Production Process

The process of preparing nickel foam by electrodeposition technology has been successfully developed through experiments. The base material used is porous open-cell foam plastic. The conductive layer can be prepared by three methods: chemical nickel plating, vacuum nickel plating and dipping conductive adhesive (palladium sol, submicron graphite emulsion, etc.). Thick nickel is electroplated in a common sulfate nickel plating electrolyte, and then a three-dimensional reticulated nickel foam material with excellent performance can be obtained through the processes of burning, reduction and annealing.

Product Application

Spongy porous metal nickel, iron, copper and their composite layer porous bodies can be used as filter carriers, chemical catalyst carriers, electromagnetic shielding materials, precious metal replacement and recovery and many other fields
