Iron nickel foam for sound-absorbing materials
Product Introduction
Iron nickel foam is an excellent performance sound absorption material with high sound absorption coefficient at high frequency; through the design of sound absorption structure, it can improve the sound absorption performance at low frequency.
Product Characteristics
Good sound insulation performance
When sound passes through nickel foam, scattering and interference occur in the porous structure of the material, so that sound energy is absorbed by the material or blocked by the porous structure. Beijing subway uses nickel foam sound insulation panels.
Preparation of nickel foam by electrodeposition technology: The substrate used is porous open-cell polyurethane sponge. After pre-scoring, it can be plated with thick nickel in ordinary nickel sulfate plating electrolyte, followed by calcination, reduction and annealing. Obtaining three-dimensional reticulated nickel foam materials with excellent performance
Through its unique porous structure, iron-nickel foam has a series of good advantages such as low density, good heat insulation, good sound insulation, and strong electromagnetic wave absorption ability. It is a new type of material that has been gradually developed with human science and technology. A series of industrial development such as aerospace and petrochemical industry.
