摘要： PROBLEM TO BE SOLVED: To use a plating sludge of a ferrite-industrial waste as a magnetic material of a ferrite tile to accelerate the recycling of the industrial waste and, at the same time, to reduce the cost of the ferrite tile. SOLUTION: A ferrite-plating sludge constituted by making the plating sludge produced from a plating liquid waste as the ferrite is mixed with an MDF cement by 70 to 92 wt.% and is kneaded to make the ferrite tile at temperature 100 to 150 deg.C and pressure 100 to 150 kgf/cm2. Since the MDF cement is solidified after a small amount of water, a hydraulic cement and a hydrophilic organic polymer are mixed with high shear force by rolling mill or the like to obtain a cement hardening body with high strength, the MDF cement is made as a matrix (a binding material of powder) to form the ferrite-plating sludge in the shape of a tile, the ferrite tile with sufficient strength is obtained without being burnt, a large-sized ferrite tile can be formed at a low cost, the plating sludge of the industrial waste can be effectively recycled to consume.

摘要： PROBLEM TO BE SOLVED: To obtain a method for manufacturing a cured wave absorber which is constituted by laminating a plurality of layers composed of alternately laminated ferrite-based magnetic layers and carbon-based dielectric layers upon a carbon layer, which is formed by kneading a thermosetting resin or filler mixed with >=30 wt.% carbon powder and molding the kneaded mixture to a layer of about 1-5 mm in thickness, so as to improve the workability and easiness in construction of the absorber and to contrive energy saving. SOLUTION: A cured radio wave absorber is constituted by successively laminating a fourth layer 14 composed of a magnetic layer containing 80 wt.% ferrite powder and having a thickness of 10 mm, a third layer 13 composed of a dielectric layer containing 30 wt.% carbon powder and having a thickness of 12 mm, a second layer 12 composed of a magnetic layer containing 80 wt.% ferrite power and having a thickness of 5 mm, and a first layer 11 composed of a carbon layer containing 30 wt.% carbon power and having a thickness of 1 mm and a mesh resistance of 40 Ω(square) upon another. Consequently, the radio wave absorber can obtain a radio wave absorption factor of 97% over a wide frequency range from a lower limit frequency of about 300 MHz to an upper limit frequency of about 1,200 MHz.
