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.
Why do you need an electromagnetic radiation protective head cover?
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. The nervous system is very sensitive to the effects of electromagnetic radiation. After repeated effects of low intensity, the function of the central nervous system changes, and neurasthenia syndrome occurs. It mainly has headache, dizziness, weakness, memory loss, sleep disorders (insomnia, dreams or Drowsiness), dozing off during the day, irritability, sweating, palpitations, chest tightness, hair loss, etc., especially difficulty in falling asleep, weakness, hyperhidrosis and memory loss are more prominent, all of which indicate that the brain is dominant in the inhibition process, so the victim In addition to the above syndromes, there is also a short-term memory loss, the visual motor response time is prolonged; the hand-brain coordination movement is poor, the performance slows down the digital recording, and there are more errors.
Swiss standard requirements:
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.

Electromagnetic radiation protective cap is suitable for people who work long hours or live in areas with large electromagnetic waves. such as computer, printer, radar contact, and wireless testing personnel as well as radio, telecommunications, communications, computer room, laboratory workers, etc. Electromagnetic radiation protective cap can protect against computer radiation, WIFI radiation, monitoring and radiation, protection against the radiation of the base station, radiation of the laboratory and other kinds of radiation. It is the ideal protective products for the army, banking, communications, electricity, schools, media, scientific research and other industries.
Electromagnetic radiation protective head covers
The main radiation protection component of head cover:
100% Silver fiber
Frequency range and shielding effectiveness:
Frequency range: 9KHz-40GHz
Shielding effectiveness: 45.0dB-68.6dB
Fabric analysis:
The silver fiber radiation protection head cover 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, the magical effect of silver fiber. Silver has the most effective antimicrobial properties. Silver fiber radiation-proof fabric made of silver-containing fiber using 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, is the production of radiation-proof head cover ideal fabric. Its anti-radiation effect is superior to radiation-proof fabric made of other metal materials, which can be worn close to the body and beneficial to the human body.
Anti-electromagnetic wave head cover shielding principle:
The metal is highly conductive and has an electromagnetic shielding function. When a people wears an anti-electromagnetic wave clothing to contact an electronic device, the anti-electromagnetic wave head cover can quickly and effectively conduct electromagnetic waves, thereby protecting the body from electromagnetic waves.
The maintenance method of silver fiber:
Silver fiber exposed to the air can not avoid oxidation, the fabric will be black or yellow, is a normal phenomenon, does not affect the shielding effect. To reduce the oxidation of washing, it is recommended to keep the head and face clean when using, if do not use, it is recommended sealed.
1. It is recommended to wash with well water, mineral water, pure water; (Reason: Some tap water contains chloride ion, and if the chloride ion is excessive, it is easy to react with silver to reduce the damage to silver by alkali and chlorine)
2. Modest amount of neutral detergent, washing for a short time; (Do not use acidic detergent or laundry detergent)
3. Can not rub and washing machine wash. Can not be bleached, After washing, you can’t wring it, pick up directly from the water and hang it in a ventilated and dry room, avoid exposure;
4. It is recommended to wash or wash as little as possible to prevent improper washing effect of shielding.
[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 suits cannot be based on the strength of mobile phone signals.
My anti-radiation head covers 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:
(1)Metal fiber
Ignite the attached fabric sample and find that the burnt sample is a very clean and fine network metal, which indicates that the fabric is very good in material and can effectively shield the radiation.
(2)Silver fiber
The attached fabric sample is ignited and burned to a black globule after being completely burned with fire. After being crushed by force, it can be turned into a powder, which indicates that the material of the fabric is very good and can effectively shield the radiation.
2.Conductivity test method:
Radiation protection clothing and ordinary clothing fabrics are essentially different. Since metal fiber and silver fiber can conduct electricity, radiation protection suits are electrically conductive, while ordinary clothes are not electrically conductive. Bring your own multimeter, or take the radiation protection suit to the appliance maintenance department to check the conductivity of the radiation protection suit.
(1)Ordinary clothing detection
The multimeter is adjusted to the 200Omega or 2KOmega position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the resistance value is 1 and the value of the multimeter when the object is not tested is 1, indicating that the ordinary fabric is non-conductive.
(2)Metal fiber testing
The multimeter is adjusted to the 2kOmega gear position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the resistance value fluctuates around 0.421KOmega, indicating that the metal fiber radiation protection suit has conductivity, so it has anti-radiation effect.
(3)50% Silver fiber testing
The multimeter is adjusted to the 200 Omega gear position. When the multimeter pen touches the test fabric and the distance is l0cm, the measured resistance value fluctuates around 1.1 Omega, indicating that the conductivity of the 50% silver fiber radiation protection suit not only is better than that of the metal fiber but also the radiation protection effect also better than metal fiber.
(4)100% Silver fiber testing
The multimeter is adjusted to the 200 Omega position. When the multimeter pen is in contact with the test fabric and the distance is 10cm, the measured resistance value fluctuates around 0.4 Omega, indicating that the conductivity of the 100% silver fiber radiation suit is better than that of the 50% silver fiber fabric. The anti-radiation effect is also better. It can be seen from the test that the resistance value of 100% silver fiber is relatively small in the fabric, so the conductivity and anti-radiation effect of 100% silver fiber are also better.
3. Conductive test:
The essential difference between radiation-resistant fabrics and ordinary fabrics is that radiation-proof fabrics are conductive and ordinary fabrics are non-conductive, so test the radiation resistance with a multimeter to see if it is effective.(If there is no multimeter at home, you can take the clothes to the appliance repair department, let the maintenance master test).
4.Professional radiation equipment test method:
The first step: using radiation equipment to detect the host, radiation equipment will display the corresponding radiation value.
The second step: use radiation suits to block the back of the chassis, in the middle of the radiation equipment and the rear of the host computer to block a layer of radiation protection suits, then see the display on the instrument value is 0, indicating that the host computer’s electromagnetic radiation is radiated Clothing shielded.
