Description
綿ガーゼのカオリン粘土保持力を評価するために、カオリン/水スラリーの温度を変化させた。カオリンがスラリー総重量の40%となるように水及びEPKのスラリーを調製した。綿ガーゼを様々な温度のスラリーに浸漬し、加圧下で浸潤したスポンジをローリングし、乾燥させることによって3種類のスポンジを作製した。以下の表は、各スラリーのパラメータ及び得られた結果を示す。
乾燥した綿ガーゼに乾燥したカオリンを適用した。その後ガーゼを巻いた。ガーゼ上に保持されたカオリンの量は、サンプル3(実験例1)のガーゼ上に保持されたカオリンの量より目に見えて著しく少量であった。しかしながらこのサンプルは、ヒツジの全血凝固時間を加速されていない場合の70%に加速した。
水50g、グリセロール20g及びカオリン粉末15gのスラリーを調製し、ガーゼスポンジ(Kendall Curity 2733)に浸透させるために使用した。スラリーを浸透させたガーゼスポンジを乾燥させた。清潔なガラス表面上にスポンジを保持し、鉛筆で軽くたたいた。
