MATERIAL FOR SHIELDING ELECTRONIC WAVE FORMED BY USING METAL FIBER OF HIGH MAGNETIC PERMEABILITY AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A material for shielding electronic wave formed by using metal fiber of high magnetic permeability and a method for manufacturing the same are provided to supply interior material or exterior material for construction and electronic equipments to protect the life space from the circumstance of electromagnetic wave and to shield the electromagnetic wave emitted from the electronic equipments. CONSTITUTION: Material for shielding electronic wave formed by using metal fiber of high magnetic permeability and a method for manufacturing the same include a wall paper, the strength(Hinput)(5) of an outer magnetic field and the strength(Houtput)(7) of an inner magnetic field. The wall paper(6) has a medium layer, on which the metal fiber of high magnetic permeability is dispersed, and the magnetic field of the outer circumstance is shielded with making the wall paper(6) the center. The strength(Hinput)(5) of the outer magnetic field is shielded by the wall paper(6) and the strength(Houtput)(7) of the inner magnetic field is reduced. The metal fiber of the high magnetic permeability, the diameter of which is 20-30 micrometer, and the length of which is 10-30mm, is used. And the compound metal as Fe-Ni, Fe-Si, Co-Fe-Si-B etc. is material of the metal fiber.
