<p>PURPOSE:To obtain electromagnetic wave absorbing material which shields unnecessary noise and can be used as a housing material by homogeneously dispersing the specified amounts of xonotlite and magnetite. CONSTITUTION:In case xonotlite and magnetite are mixed in such a ratio that xonotlite is set to 100pts.wt. while magnetite is under 50pts.wt., sufficient electromagnetic wave absorbing effect cannot be obtained and in case it exceeds 300pts. any improvement of effect cannot be observed and reduction of weight cannot be interfered. Therefore, magnetite is defined to 50-300pts.wt. for 100pts. wt. of xonotlite and these are homogeneously dispersed. Thereby, electromagnetic wave absorbing material which can shield unwanted noise and is suite to a housing material can be obtained.</p> |
