Description
本発明において、混合要素の全ランドのランド剪断断面積の合計は、ポリマーが混合要素に入る直前に通過するスクリューの隣接フライト間の流れ断面積の102%以上であってよい。
溶融ポリマーを搬送するスクリューの区域は、バレルの出口端部に近接した計量部を有し、この計量部に混合要素を配してもよい。この場合、計量部が両端を有すると共にこの計量部の両端の間の中間点があり、この中間点と中空空間の入口端部の方を向く計量部の端部との間に混合要素を配することができる。あるいは、計量部が1つ以下のフライトを有し、混合要素を計量部の出口端部に配したものであってよい。
混合要素は、バレル中空空間の入口端部の方を向く計量部の端部に近接しているものであってよい。
スクリューが供給部および圧縮部を有し、供給部内のフライトの体積と計量部内のフライトの体積との比が1.8未満であってよい。
混合要素が少なくとも3つの入力溝と少なくとも3つの出力溝とを有し、より好ましくは少なくとも5つの入力溝と少なくとも5つの出力溝とを有することができる。
バレルの中空空間が円柱形であってよい。
装置がポリマー押出機の一部であってよい。
装置が射出成形機のポリマー押出機であってよい。
W=P(cosθ)−e
ここで、「θ」は、スクリューの長手方向の軸に垂直な方向に対するフライトの角度であり、「P」はピッチであり、「e」はフライトの厚さである。
実施例1において、本発明によるスクリューを製造し、ポリアセタール熱可塑性樹脂を射出成形するのに使用した。ポリアセタール樹脂を、直径が約2から4mmの粒状ペレットの形態で、供給ゾーンに導入した。ポリアセタール樹脂は、デルリン(Delrin)(登録商標)500P、すなわち、添加された熱安定剤および潤滑剤約1重量%と混合され、融点が177℃であり(ISO3146方法C2)、2.16Kgの重量で、190℃の温度における、標準技術(ISO1133)によるメルトフローレートが15g/10分であり、本願特許出願人から入手可能なポリアセタール樹脂であった。
実施例3および4において、実施例1で上述されたような、混合エレメントを備えたスクリューを、実施例1の射出成形機に使用して、同じ配合のポリアセタール熱可塑性樹脂組成物を射出成形したが、それを異なった形態でスクリューの供給セクションに導入した。実施例3において、射出成形前に、別個の混合操作で、組成物の成分を予め混合した。実施例4において、前の予めの混合操作を伴わずに、組成物の成分を射出成形スクリューに直接導入した。比較例5において、実施例3および4で使用された射出成形機を、実施例4の多数の成分樹脂を射出成形するのに使用したが、使用されたスクリューは、混合エレメントを含まない、比較例2のスクリューであった。
