Problems solved by technology
[0003] In the process of traditional fabric anti-electromagnetic radiation performance testing, the fabric will be pressed tightly. When the fabric is squeezed, the inner textile fibers will be stacked, and the surface area for absorbing electromagnetic radiation will decrease, which will affect the accuracy of the experiment. If the fabric is not pressed tightly, part of the electromagnetic radiation will pass through the remaining space and diffract to the outside world without decay, which will have a certain impact on the human body during the long-term testing process, and the remaining space will also affect time. Accuracy affects

The invention discloses a fabric anti-electromagnetic radiation performance tester and a testing method thereof, belongs to the field of testers, and can debug the rising height of a constant pressure protection assembly according to the thickness of a fabric, so that the lower end of a flange coaxial upper testing device is just in contact with the fabric; through wrapping of the balance pressure protection assembly, part of electromagnetic radiation diffracted to the outside world can be absorbed, the possibility that the electromagnetic radiation affects the human body is reduced, the balance pressure protection assembly can automatically generate heat after absorbing the electromagnetic radiation, and therefore the electromagnetic radiation can be prevented from being damaged. When electromagnetic radiation is generated, the upper end of the balance pressure protection assembly expands due to the heat of the balance pressure protection assembly, so that the balance pressure protection assembly is only attached to the lower end of the flange coaxial upper testing device, the sealing effect between the balance pressure protection assembly and the flange coaxial upper testing device is improved, and the possibility that the electromagnetic radiation diffracts to the outside is further reduced.
Description
technical field [0001] The invention relates to the field of testing instruments, in particular to a fabric anti-electromagnetic radiation performance testing instrument and a testing method thereof. Background technique [0002] Electromagnetic radiation is composed of electrical energy and magnetic energy co-transferred in space. This energy is generated by the movement of charges. "Includes all kinds of electromagnetic radiation, from extremely low-frequency electromagnetic radiation to extremely high-frequency electromagnetic radiation, and there are radio waves, microwaves, infrared rays, visible light and ultraviolet light between the two. The general definition of the radio frequency part of the electromagnetic spectrum refers to Radiation with a frequency ranging from 3 kHz to 300 GHz, some electromagnetic radiation has certain effects on the human body. [0003] In the process of traditional fabric anti-electromagnetic radiation performance testing, the fabric will...
