Description
図1に示すグリーン成形体70は、原料組成物を押出成形することによって得られたものである。図1の(a)に示すように、グリーン成形体70は多数の貫通孔70aが略平行に配置された円柱体である。貫通孔70aの断面形状は、図1の(b)に示すように正方形である。これらの複数の貫通孔70aは、グリーン成形体70において、端面から見て、正方形配置、すなわち、貫通孔70aの中心軸が、正方形の頂点にそれぞれ位置するように配置されている。貫通孔70aの断面の正方形のサイズは、例えば、一辺0.8〜2.5mmとすることができる。なお、グリーン成形体70を所定の温度で焼成することによってハニカム構造体が製造される。
図2〜4を参照しながら、本発明に係る押出成形装置の実施形態について説明する。図2に示す押出成形装置10は、粉末状又はペースト状の原料組成物からグリーン成形体70を製造するためのものである。
次に、押出成形装置10を用いてグリーン成形体70を製造する方法について説明する。まず、原料組成物を入口1aから流路1b内に導入する。スクリュー2A,2B及びローラ3aを作動させることによって原料組成物を混練すると共に下流側に移送する。混練物を整流板5の貫通孔6を通過させて流速分布を均一化させた後、抵抗管9を通じてダイ8に導入する。ダイ8の下流側における原料組成物の線速度は10〜150cm/分程度とすることができる。
