実施例１
この実験では、ヘキサメタリン酸ナトリウム分散剤の、様々な不十分(starvation)量（ごく低い）での添加による、粉砕した炭酸カルシウムのスラリー特性への効果を測定した。
低濃度固形分（25重量％）において、250kWh/tでの実験室用のスラリーのサンドグラインド粉砕によって、粗い炭酸カルシウムの供給から粉砕炭酸カルシウムを調製した。乾燥炭酸カルシウムに対して、それぞれ0.1、0.2、および0.3重量％の分散剤を含有する、サンドグラインド粉砕した物質の３つのバッチを調製した。次いで、３つのバッチを、1.72MPa(250psi)の低圧ピストン圧縮によって脱水し、ケーキを得た。ケーキの透水性および抵抗は、下に説明するテスト方法によって、各ケースにおいて圧縮を行う間に測定した。次いで、３つのケーキをそれぞれ２つのサンプルに分け、そして、ケーキのサンプルを、0.5％および0.6％の部分的に中和したポリアクリル酸ナトリウム分散用試薬（60％中和）を用いて懸濁（スラリー化(slurry makedown)）し、72-73重量％の固形分を含有する高濃度固形分スラリーを得た。次いで、T（スラリー化後の時間）=０、１、24、および168時間において、ブルックフィールド社製粘度計で100rpmにおけるスラリー粘度(Brookfield viscosities)を測定した。さらに、各サンプルの粒径分布、d50、および分布の鋭さを圧縮後に測定した。
（１から６の番号を付した）６つのサンプル、および対応するコントロール（分散剤不使用）の結果を下の表１に示す。
