Hello everyone, I am the editor. Today, I will introduce the absorbing materials to you. The following content is organized by the editor, and the relevant content is for reference.
Absorbing material refers to a type of raw material that can digest and absorb the radio wave energy projected on its surface, and the reflection surface, mapping and transmission are not large. Radio wave absorbers are divided into conductive loss, dielectric loss, and magnetic loss, etc., and can be divided into conductive absorber materials, electrical electrode absorber materials, and magnetic absorber materials. The key is to use dielectric loss as the loss principle. Under the effect of an external alternating electric field, the electronic devices in the raw material chemical fiber cause vibration, which converts electrical energy into energy for dissipation and consumption. Research shows that this kind of raw materials has relatively light weight (1 kg/m2), wide digestion and absorption frequency band (10MHz-18GHz), good digestion and absorption characteristics (5-30db), and strong aging resistance (-40℃—180℃) , Anti-aging, easy to bend, can be cut at will, water resistance, compression resistance, long-term application, non-toxic environmental protection and other outstanding advantages.
In the custom manufacturing of absorbing materials, the main parameters of the magnetic induction digestion and absorption of the raw materials can be adjusted according to the length, diameter, sorting method, thickener composition, etc. of the chemical fiber. According to the customer must produce (10MHz-18GHz) The total width of the same frequency band, different main purposes (for national defense, industrial production and civilian use), etc., different thickness from (0.5-6 mm) and different thickness (tablet type, wave pattern, honeycomb, etc.) Look like.
Key main uses of absorbing materials: mobile phones, instrumentation equipment, high-frequency machinery and equipment, microwave heating active devices, radar detection and microwave communication system software noise suppression, anti-interference signals and other technical fields, based on different applications The frequency range can adjust the depth and secret of the new functional materials to make radio wave digestion and absorption film of different thickness and effect. The thickness is 0.1-1.0 mm, which can be produced according to customer requirements. The absorbing material.
