<P>PROBLEM TO BE SOLVED: To provide a micro mixer which rapidly and uniformly dissolves gas into a melted resin by efficiently dispersing the melted resin and the gas. <P>SOLUTION: The micro mixer mixes the melted resin and the gas, and dissolves or disperses the gas into the melted resin. The micro mixer 10 comprises a first box 11 in which a first introduction passage for introducing the melted resin therein is formed, and a second box 14 in which a second introduction passage for introducing the gas is formed and a plurality of fine holes for blowing out the gas by dividing the introduced gas are formed, and which is arranged in the first box. The micro mixer mixes the melted resin and the gas by merging them in a fine region in which an inner wall of the first box 11 and an outer wall of the second box 14 are arranged so as to approximate each other, and which is composed of intervals between the inner wall and the outer wall. <P>COPYRIGHT: (C)2013,JPO&INPIT |
