Description
図1は、本実施形態の押出機1を示す側面図である。図1に示されるように、本実施形態の押出機1は、可塑性のエラストマーGを混練しながら押出方向Aに押し出すためのスクリュー2と、スクリュー2を内部に配するバレル3とを含む。ここで、可塑性のエラストマーGとして、例えば、未加硫ゴム、熱可塑性エラストマーなどが適用しうる。
ガーベイダイの吐出口の断面積Saと、この吐出口から押出成形された成形物の60分後の断面積Sbとの比Sb/Sa(単位%)で評価した。数値が小さい方が形状の安定性に優れている。
JIS K6300に準拠し、130℃におけるムーニー粘度(1+4)を測定し、従来例を100とした指数で示す。数値が小さい方が可塑性能に優れている。
吐出口から押出成形された成形物の表面粗さ(算術平均粗さRa)を測定した。数値が小さい方が表面が滑らかである。
120℃の温度制限下において押出機を運転し、そのときの吐出量を従来例を100とした指数で示す。数値が大きい方が吐出量が多く良好である。
