Description

Technical Field

[0001] The utility model relates to the technical field of microwave absorption performance detection, in particular to a test tooling for magnetic microwave absorption films. Background Art

[0002] Microwave absorption materials refer to a class of materials that can absorb or significantly weaken the electromagnetic wave energy received on their surfaces, thereby reducing electromagnetic wave interference. In the existing technology, with the development of modern science and technology, the impact of electromagnetic wave radiation on the environment is increasing day by day. At airports, flights are often delayed because electromagnetic wave interference prevents them from taking off. In hospitals, mobile phones often interfere with the normal operation of various electronic diagnostic instruments. Therefore, controlling electromagnetic pollution and finding a material that can resist and weaken electromagnetic wave radiation - microwave absorption materials - has become a major topic in materials science. In engineering applications, in addition to requiring microwave absorption materials to have high absorption rates for electromagnetic waves in a relatively wide frequency band, they are also required to have properties such as light weight, temperature resistance, humidity resistance, and corrosion resistance.

[0003] In existing equipment, the microwave absorption materials to be tested are placed on the ground or on tables and chairs for penetration testing. When the microwave absorption materials are placed, the outer walls of the microwave absorption materials are prone to abrasion with the fixing mechanism, causing wear on the outer walls of the microwave absorption materials. After multiple adjustments, the detection results of the microwave absorption materials are prone to deviation, resulting in a decrease in the detection accuracy of the detector. For this reason, a test tooling for magnetic microwave absorption films is proposed. Content of the Utility Model
