The type of microwave absorbent material

Author:admin   AddTime:2021-02-06

Patches don't fit into complex shapes. The magnet insulation film and coil fit better, the magnetic sheet can withstand a certain degree of bending can be better with the coil fast, when receiving external force action can still remain intact, improve product life. However, complex structural design can be achieved, using patches such as rubber sheets, ceramic sheets (role: for the decoration of tables and bed cabinets) and plastic (structures: synthetic resins, plasticizers, stabilizers, color materials).
Structural microwave absorption material

Made from non-metallic composites as carriers by adding absorbents. A manufacturer of absorbent materials is a class of materials that absorb or significantly reduce the energy of electromagnetic waves projected on its surface, thereby reducing the interference of electromagnetic waves. In engineering applications, in addition to requiring absorbent materials to have a high absorption rate of electromagnetic waves in the wider band, it is also required to have light weight, temperature resistance, moisture resistance, corrosion resistance and other properties. Usually epoxy resin (Resin) and thermoplastic materials as a base, filled with ferrite, graphite, carbon black and other absorbents, such as carbon fiber / epoxy resin, graphite / thermoplastic materials, boron fiber / epoxy resin, graphite fiber / epoxy resin, etc. This type of material can not only reduce the scattering of electromagnetic waves, but also can withstand a certain load, lighter than the general metal material, has a certain strength and stiffness, has been applied.
Interferon-type wave absorption material

Interferon-type microwave absorption material, mainly the interference of electromagnetic waves, in the central frequency point of the incoming electromagnetic waves and reflected electromagnetic waves phase opposite (phase difference of 180 degrees) and offset each other (due to the opposite effect to eliminate each other). 5G absorbent material in the design, to consider electromagnetic waves encountering the surface of the absorbent material, as far as possible completely through the surface, reduce reflection; The properties of this material are narrow frequency ranges, which can be used | high-frequency environments and can be made thinner.
Absorption-type wave absorption material

The dielectic and magnetic losses of the inductive electromagnetic radiation in the object are large, and electromagnetic energy is converted into heat or other forms of energy. Absorption-type microwave absorption materials are divided into electro-loss type and magnetic loss type. In general, electrolytic materials absorb higher frequencies, while magnetically damaged materials absorb low frequencies more efficiently. If the two are combined, a wide frequency range of absorbent materials can be made. The electrode microwave absorption material is based on carbon (C) powder or metal particles to create a gradient dielectic ability absorbent material by thickness, depth change and changing the type of filler. Magnetically damaged microwave absorption materials are thin layers of material filled with magnetic materials such as ferride or niobium-based iron powder, such as epoxy polysulfur (chemical symbol: S), silicone rubber, urine, and fluorine elastic systems.
