EMF shielding fabric

Description

What is electromagnetic radiation?

Electromagnetic radiation is “non-ionizing radiation,” including microwaves and electromagnetic fields (EMF). Any type of electrical appliance produces non-ionizing radiation, including cell phones, computers, televisions, wires, and ultrasound.
The influence of electromagnetic radiation on human health:
Electromagnetic wave radiation has been listed by WHO as the fourth largest source of environmental pollution after water, atmosphere and noise. It has become an invisible “killer” that harms human health. Electromagnetic radiation can generate a lot of free radicals, interfere with communication between cells, hinder hormones and the release of (such as melatonin). Causes cancer, leukemia, cardiovascular and cerebrovascular diseases, miscarriage, menstrual disorders, sexual decline, insomnia and neurological disorders. People who work, study, and live in a concentrated environment of radiation sources are prone to insomnia and dreams, memory loss, physical weakness, and low immunity. The growth rate of cancer cells is 24 times faster than that of normal people. The Swiss standard requires safety within 2mGs outside the 2m range of appliances. The human body can only withstand 2mGs radiation, but it is said that all kinds of household appliances: mobile phone 200mGs, computer 20 ~ 40mGs, copier 40mGs, microwave oven 200mGs, hair dryer 100mGs, TV 20 ~ 40mGs, refrigerator 20 ~ 40mGs. Studies have shown that long-term effects of electromagnetic radiation above 2mGs can cause illness in humans.
The products we sell:
Electromagnetic radiation protective 100% silver fiber Silver-plated mesh fabric

Fabric width: 1.5m

Antibacterial rate:≥99%

Note: Antibacterial only refers to anti-Escherichia coli, anti-Staphylococcus aureus, anti-Candida albicans, against Pseudomonas aeruginosa.

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 made of nanotechnology 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.
Frequency range and shielding effectiveness:

Frequency range: 9KHz-40GHz

Shielding effectiveness: 40.2dB-52.7dB
Shielding principle of 100% silver fiber Silver-plated mesh fabric:
The ring-shaped shielding network composed of silver fibers can generate induced current, which in turn generates a reverse electromagnetic field to shield radiation.
Application scope of 100% silver fiber Silver-plated mesh fabric:
100% silver fiber Silver-plated mesh fabric 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.
How to clean the 100% silver fiber Silver-plated mesh 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.
[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.
