Fabric shielding principle:
The fabric contains a dense metal mesh. The metal mesh forms a safety ldquoshield coverrdquo, which can effectively block the electromagnetic wave radiation generated by the electrical appliances and Avoid radiation damage to the human body.
Recommended use environment:
The maintenance method of the fiber:
1. Hand wash, can be brushed with soft brush, avoid rubbing and machine washing;
2. After washing, you can’t wring it, remove it directly from the water, and keep it cool;
3. Don‘t irons;
4. It is recommended not wash as much as possible in case of improper washing.
[NOTE]: Cell phone signal does not equal cell phone radiation
The mobile phone signal is a high-frequency microwave signal. It is the ability of the mobile phone itself to receive signals. It is basically harmless to the human body. The mobile phone signal has spread all over the world and is also supported by the countries of the world. The mobile phone can automatically search for signals. The steel in high-rise buildings is all steel. The elevator can receive signals, so the mobile phone initiative to search for signals has its own particularity. The protective effect of radiation protection fabrics cannot be based on the strength of mobile phone signals.
My anti-radiation fabrics are protected against electromagnetic waves generated by the sudden increase or decay of electric currents in electronic components, and are not anti-cell-phone signals.
Fabric test methods:
1.Fabric combustion method:
The residue after the cloth is fully burned is network metal, These metal meshes are used to shield electromagnetic radiation, so it can be proved that the cloth can effectively shield electromagnetic radiation.(This method is only suitable for metal fiber fabric)
2.Speaker noise interference method:
Electromagnetic radiation will interfere with the normal operation of audio equipment, causing the audio equipment to emit "si si" noise. After the audio equipment is completely covered with electromagnetic radiation protective clothing, the "si si" noise will weaken or disappear.
3.Conductivity test method:
The difference between radiation protection fabrics and ordinary fabrics is that radiation protection fabrics are conductive, while ordinary fabrics are non-conductive. use a multimeter to test whether the fabric has resistance(resistance proves that the fabric is conductive), you can know whether the fabric has radiation protection.
4.Professional radiation equipment test method:
The first step: Use the electromagnetic radiation detector to detect the radiation of the computer screen, and the corresponding radiation value will be displayed.
The second step: Completely cover the computer screen with electromagnetic radiation protective clothing and then use an electromagnetic radiation detector to detect the radiation of the computer host, the radiation value will decrease or become zero.
