Pretreatment of foam nickel

Pretreatment of foam nickel

Sound insulation: Through additional processing, it is possible to intercept high noise and achieve good sound insulation effect. Electronic wave shielding: Shielding around 90dB of electronic waves. 4. Processing performance: capable of cutting. In the field of functional materials - can be used as sound-absorbing materials to absorb wave energy energy; Noise reduction, vibration absorption, buffering, electromagnetic shielding, stealth technology, flame retardancy, insulation, etc.

Nowadays, nickel mesh materials can be seen in many places, so how was this type of material produced?

1. General production process

As a kind of foam metal, there is a general production process beside the production process. It is to conduct the polyurethane sponge through some special processes next to the production process, and then use the method of electro stacking. After stacking, sintering obtains this information. However, it is worth noting that there are three main methods used for conductivity treatment in the production process, including chemical plating, coating with conductive adhesive, and vacuum plating.

The process of electro deposition, in practice, mainly relies on silver sulfate or amino sulfur salts, and then allows nickel, a metal, to be plated on polyurethane cotton. Next to the production and manufacturing process, according to the current sintering process, the main method used next to the production process is to first use air to burn polyurethane cotton; After completing the above processes, hydrogen gas is used as the rehabilitation gas to sinter two processes, which can complete a series of production processes.

2. Change production process

Next to the production process, the effectiveness of general production processes and materials is not ideal; With the continuous exploration of the production process of nickel mesh, a change in the production method of this material has also been obtained.

Next to the production process, it is still necessary to conduct electricity on the polyurethane sponge first. After completing the above series of processes, the method of electro stacking sintering is used. However, beside the sintering process, the electrodeposited foam polyurethane is pyrolyzed and sintered directly in the rehabilitation atmosphere. The rehabilitation atmosphere used next to the sintering process mainly uses ammonia decomposition. The use of this modified process to produce metals significantly improves the quality of the produced metal compared to conventional production processes. It can deal with the defects of foam metal produced by general process, such as easy cracking, deformation and arching. It also has a very high yield after production, which greatly reduces the energy consumption beside the production process.
