First of all, Xiaobian can clearly explain to you that the absorbing material is not conductive, so why is the absorbing material not conductive?
Absorbing material is a kind of advanced shielding material and magnetic material. It can absorb and transform electromagnetic radiation and purify electromagnetic space environment in the largest range. From the structure and composition of the absorbing material, we can also know that the absorbing agent of the absorbing material mainly uses nickel iron alloy and some trace elements as raw materials. This kind of alloy has high permeability and can absorb electromagnetic wave rapidly. The surface impedance value of the whole absorbing material is 1 × 10-6, which is non-conductive material, so the absorbing material is insulating and non-conductive.
Next, we will analyze why it does not conduct electricity
1、 The traditional shielding material is a kind of conductive shielding product. Its shielding method is reflection shielding, that is, the conductor has reflection effect on electromagnetic wave. The lower the conductivity resistivity, the more severe the reflection of electromagnetic wave on metal conductor, such as copper, aluminum, silver, etc., because this conductive shielding material can only suppress electromagnetic wave, reduce electromagnetic wave radiation to interfere with other components The electromagnetic radiation has not been completely eliminated. With the rated frequency of electronic products chip becoming higher and higher, the radiation is getting bigger and bigger. Therefore, new shielding materials must be developed to solve this problem. The generation of wave absorbing materials is an advanced shielding method. The main raw material is nickel iron alloy with very high electrical resistance, which can quickly absorb clutter and achieve shielding purpose without conductivity Performance.
2、 The absorbing material is a magnetic functional material based on ferronickel alloy. Let's take a comparative look at the common resistivity of metal materials
Material resistivity (Ω m)
1. Gold 2.40 × 10-8
2. Silver 1.65 × 10-8
3. Copper 1.75 × 10-8
4. Aluminum 2.83 × 10-8
5. Iron 9.78 × 10-8
6. Tungsten 5.48 × 10-8
7. Platinum 2.22 × 10-7
8. Mercury 9.6 × 10-7
9. Manganin 4.4 × 10-7
10. Constantan 5.0 × 10-7
11. Ni Cr alloy 1.0 × 10-6
12. Fe Cr Al alloy 1.4 × 10-6
13. Ferronickel alloy 1.6 × 10-6
From the above comparison, it can be seen that the resistivity of metal is small, while that of alloy is relatively large. The resistivity of ferronickel alloy is as high as 1.6 × 10-6, and the resistivity is very large. In conclusion, the microwave absorbing material is non-conductive.
