INDIVIDUAL screen for protection against electromagnetic radiation from mobile phones CELLULAR

摘要

A device for protection against mobile cellular phone electromagnetic radiation consists of personal protective screen of rectangular shape with sides corresponding to the size of a cell phone. Screen of the protective device is designed as a planar non-separable multi-layer structure comprising parallel layers of materials with different characteristics. Lower (directed toward the human body), the shield layer material made of a metallized plastic film with the magnitude of the reflection of radio waves close to unity. On the surface of the metallized layer is applied a layer of rubber composition a thickness of 2.5 mm, which is entered ferromagnetic particulate filler such as iron carbonyl pretreated in attritor, a particle size of 3-5 microns and a mass concentration in the mixture to 80%. Layers of materials are bonded together with an adhesive composition coated on one side of a metallized polyethylene terephthalate film. Collectively, both layers form the absorber material elekromagnitnyh waves from radio wave reflection coefficient from the magnitude of the polymer layer of from 0.05 to 0.35 than the shield effect is eliminated on the receiver performance and the cell phone transmitter. To impart the required operational protective screen, ergonomic and aesthetic and hygienic properties of the outer surface of the protective screen have protective and decorative polymeric coating obtained, e.g., by laminating a colorless transparent polypropylene film; P.formuly 1 and 2 illustrations., One source of information
