Application of copper plastic composite belt and two crystallization annealing process
Apr 28, 2018

In previous articles, we talked a lot about the use of copper plastic composite strips. Simply speaking, the copper plastic composite belt is mainly used in electromagnetic shielding and signal shielding. It can effectively suppress electromagnetic interference, prevent electromagnetic waves from harm to the human body, and avoid the need of voltage or current to affect the function. Suitable for digital cameras, mobile phones, DVD, HVD precision electronic products, computer communications, wires, cables, high frequency transmission, isolation of electromagnetic interference. The bonding force is strong and the conductive property is good.

 

When it comes to the two crystallization annealing process of the copper plastic composite belt, we should also pay attention to the incomplete recrystallization annealing of the product, including two kinds of stress annealing and partial softening annealing, mainly used in the pure copper plastic composite belt and the production of the semi hard products of the aluminum alloy without heat treatment.

 

The two crystallization annealing process of the copper plastic composite belt means that when the internal stress annealing is eliminated, the microstructure of the metal is not changed, and the deformation structure is still maintained, and the residual stress inside the material is eliminated only. When some softening annealing is made, the microstructure of the metal is partly changed. There is a certain amount of recrystallization in addition to the deformation of the microstructure. According to the different mechanical properties of materials, annealing systems with different temperatures or time can be adopted.

 

The two annealing process of the copper plastic composite belt should also pay attention to the formulation of the annealing system, not only to consider the annealing temperature and time of heat preservation, but also to consider the alloy composition, impurity content, cold deformation degree, intermediate annealing temperature, heating speed, cooling rate, volume weight and high stacks after this. The effect of product specifications.

 

With regard to the two crystallization annealing process of the copper plastic composite belt, it is necessary to pay attention to the change curve between the annealing temperature, the heat preservation time and the mechanical properties when the reasonable and incomplete recrystallization annealing system must be formulated. After that, the two annealing process conditions of the copper plastic composite belt must also have the required properties. Indicators determine the range of annealing temperature and holding time. Such processing can also guarantee the quality and performance of the copper plastic composite belt.http://www.copolymercoatedaluminumtape.com/
