100% Silver fiber fabric bucket hat
(Outer fabric: Nylon; inner fabric: 100% silver fiber)
Frequency range: 9KHz-40GHz
Shielding effectiveness: 45.7dB-69.2dB
The silver fiber is a high-tech product obtained by permanently bonding silver to a fiber surface through a special technique. This structure not only makes the silver fiber maintain the original textile property, but also gives it all the The magical function of silver. Silver fiber radiation-proof fabric is the latest radiation-proof technology in the world after metal anti-radiation fiber cloth. It has the functions of radiation protection, anti-bacterial and anti-fouling. Its anti-radiation effect is superior to radiation-proof fabric made of other metal materials.
The maintenance method of silver fiber fabric:
Silver fiber exposed to the air can't avoid oxidation, the fabric will be black or yellow, is a normal phenomenon, doesn't affect the shielding effect. If don't use, it is recommended sealed.
1. Use filtered or purified water to wash the product, and avoid using tap water (to prevent damage to the silver fibers from chlorine ions in tap water)
2. Wash with neutral detergent for a short time; (Don't use acidic detergent or laundry detergent)
3. Can't washing machine washing, can't be bleached, after cleaning, don't wring out, pick up directly from the water and hang it in a ventilated and dry room, avoid direct sunlight exposure, don't recommend ironing;
4. It is recommended to wash it as little as possible prevent improper washing from affecting the shielding effect.
Application scope of electromagnetic radiation protective face mask:
Electromagnetic radiation protective face mask can resist computer radiation, WIFI radiation, monitoring radiation, base station radiation, laboratory radiation, etc. It is an ideal protective product used in the military, banking, communications, power, schools, media, scientific research and other industries.
[NOTE]: Cell phone signal doesn't equal cell phone radiation
Some buyers often mistakenly believe that anti-radiation products can shield mobile phone signals. In fact, the radiation from mobile phone is mainly near-field radiation, which comes from the electronic components of the phone itself, rather than from the signals emitted by the base station. So it is unscientific to test whether the anti-radiation product is anti-radiation by shield mobile phone signals!
The anti-radiation products are designed to protect against electromagnetic waves caused by the sudden increase or decay of electric currents in electronic components, the ring-shaped shielding network composed of metal fibers or silver fibers can generate induced current, which in turn generates a reverse electromagnetic field to shield radiation. But they don't shield against 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:
Turn on the audio equipment, the mobile phone next to the audio equipment, so that another person to call the phone, this time you can usually hear the sound of "si si" noise. The reason is that when the mobile phone calls will emit electromagnetic radiation to interfere with the normal operation of the audio equipment, and then cover the audio equipment with a protective clothing completely, then dial this mobile phone, the sound of "si si" voice to eliminate or weaken. This test can prove radiation protection clothing to the shielding effect.
3.Conductivity test method:
electromagnetic radiation protective fabrics and ordinary fabrics are essentially different. electromagnetic radiation protective fabrics are electrically conductive. When the multimeter probes touch the test fabric and the distance between the multimeter probes is 10cm, The multimeter shows a resistance value greater than 0, indicating that the fabric has conductivity and anti-radiation effect.
4.Professional radiation equipment test method:
The first step: Use an electromagnetic radiation detector to detect the radiation value of the computer screen;
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 screen, the radiation value will decrease or become 0
