With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. At airports, airplanes and flights are delayed due to electromagnetic interference. In hospitals, mobile phones often interfere with the normal operation of various electronic diagnosis and treatment equipment. The absorbing material is a kind of composite material with excellent absorbing ability for electromagnetic waves. This kind of absorbing material is to form a magnetic alloy with high magnetic permeability through physical refinement and magnetic field treatment, and disperse it uniformly in a polymer to form a magnetic alloy. Composite materials.

The principle of the absorbing material is based on the magnetic microwave absorber, which converts the electromagnetic waves emitted by electronic equipment into heat energy by means of insulation loss, magnetic loss and impedance loss to achieve the effect of reducing electromagnetic radiation. It has high permeability and wide selection of frequency bands. And other characteristics, and can be targeted for specific frequency band development.



The absorbing material has good absorption characteristics in the range of 10MHz~6GHz, which can avoid electromagnetic interference or leakage caused by secondary reflection. The products are mainly absorbing patch types, which can also be processed into various shapes according to customer needs. Absorbers can be used in electronic equipment cavities such as notebook computers, mobile phones, and communication cabinets. The absorbing material has good electromagnetic wave absorption effect and wide absorption frequency. It can be customized according to the frequency band required by the customer. It is thin and cost-effective, and has a wide range of uses and applications.
As the international standards for electromagnetic interference control become more and more stringent, our country is also in line with the international standards, speeding up the control of electromagnetic noise, especially electronic products. Therefore, the treatment of electromagnetic pollution and the search for a material that can withstand and weaken electromagnetic wave radiation-absorbing materials have become a major issue in materials science.
