Progress in technology, high efficiency utilization of spectrum resources, makes more and more radio signals, while facilitating working life, also aggravating the problem of pollution due to electromagnetic waves generated by radio signals. Radio waves are the fourth largest environmental pollution source, which will be reported after the air, air, and noise. The human body will cause health and potential hazards under high-strength radio waves, such as: the weak current under strong magnetic field is interfered with external magnetic field, strong high frequency radio The wave body temperature will have weak changes, which will produce unpredictable health risks.
Under industrial environments, online computer rooms are high data volume, high data secret environmental places. The impact of high electromagnetic waves under the environment in the environment can lead to irreversible losses, and it is essential for electromagnetic protection for electromagnetic protection on the environment of the network.
Shenzhen national test has many years of environmental radio wave shielding attenuation experience, environmental comprehensive measurement assessment, reduce electromagnetic wave hazard, give you a "clean" electromagnetic environment.
First, the wall
1.1 HSF54 shielded coating
HSF54 shielded coating does not contain metal particles corrosion resistance, extremely strong antioxidant, very high adhesion. There is no special requirements for the shielded room structure, the construction is very simple, the same as ordinary coatings (rolls, brush a brush); more construction is convenient than the masking method of conventional steel structure, no maintenance, no occupation space and other advantages ;
Ultra-wide frequency range 9kHz-40GHz, 30dB shielding efficiency @ single layer (double layer can reach 60dB, meet A level requirements), meet the shield of wireless wave signals in work life.
1L and 5L two different specifications package, using an area of 6-8 square meters per liter, black, can be used as a wall primer. After brushing, the coating of other colors can have no effect on the shield effect (after drying of the shield).
1.2 EMI80B shield wallpaper
The EMI80B is a single metallized shielded wallpaper with environmentally friendly white wallpaper, which is used to shield high-frequency electromagnetic radiation, 80dB high shielding performance, 30m-18g wide frequency range to meet work life shielding needs. The product is more environmentally friendly after FSC certification (close to wall conductive layer, exposed space insulation)
Like conventional wallpapers, the wall is sprayed with a coating agent, and it can be attached to the wall.
Second, doors and windows
2.1 Glass shield film
High transmissive shielding film, convenient construction, 30M-18G wide frequency range (can be 40g), 19db attenuation applicable shielding place, 30dB shield attenuation applies to high requirements environment. The corresponding thickness is 37.5 um and 75um, ultra-thin and light.
2.2 Shielding curtains
Ultra-thin yarn woven cotton shielded screen material, very suitable for shielding high frequency radio waves, 30m-18g wide frequency range, 38dB shielding efficiency. Easily attenuate high-strength radio waves. The product has passed textile hazards as non-chemicals, and it is more secure, and high transmissive does not affect the sun. Do not bleach and chemical dry cleaning.
2.3 window / wind tube
40 / 50DB Shielding The invisible safety metal network is ideal for inside and outside of the window, different aperture selection, non-visual occlusion (high contact network is not clear). Construction is simple, no special requirements are required, easy to process.
Third, blocking carpet
80dB of carbonized polyester wool made of shielding materials, very suitable for wall interior, ceiling or floor intermediate layer. Very cost-effective ground shielding material.
