CERAMIC NANO PARTICLE POWDER FOR ABSORBING AND PROTECTING ELECTRON WAVE AND PIPE ABSORBING AND PROTECTING ELECTRON WAVE USING THEM

摘要

By mixing the nano-scale of a bivalent or higher metal and ferrite and carbon easily mixed with black and capable of absorbing and shielding the electromagnetic wave absorption and shielding ceramic nanoparticle powder for the above-mentioned ceramic nanoparticle powder pulverized to the present invention the thermoplastic synthetic resin the electromagnetic wave absorption and shielding relates to an electromagnetic wave absorption and shielding composition capable of producing a superior pipe, cable or the like.; Ceramic nanoparticle powder of the present invention, the pulverized mixture by weight of the nanometer (nm) size in the mixer, based on _{Pb, As, Al 2 O 3} , Sb, Cn, C , and a metal selected from the mixtures of powders 50 to 70% by weight and, as the magnetic material of ferrite powder, 20 to 40% by weight ground to a nano-size, characterized in that a mixture of 10 to 30% by weight of carbon black powder, ground to a nano-scale.
