・平坦な底部を有するプラスチックトレイ。このトレイは、その上にガラスフリットをその壁部に触れることなく載置することが可能な十分な広さを有する。この試験方法には、22.9cm×22.9cm(9インチ×9インチ)の底面積と、1.3〜2.5cm(0.5〜1インチ)の深さを有するプラスチックトレイが一般的に使用される。
・「C」(20〜25ミクロン)の空隙率を有する直径12.5cmの焼結ガラスフリット。このフリットは、食塩水中での平衡化により事前に作成される。フリットは、少なくとも2部の新鮮な食塩水で洗浄するのに加えて、AUL測定前に食塩水中に少なくとも12時間浸漬させるべきである。
・ワットマン(Whatman)社製のグレード1、直径12.5cmの円形のフィルタ紙。
・食塩水の供給(0.9重量%塩化ナトリウム蒸留水溶液)。
AUL(0.9psi)=(B−A)/SA
ただし、
A=乾燥SAPを含むAULユニットの重量
B=60分間吸収後の、SAPを含むAULユニットの重量
SA=実際のSAPの重量
・電子てんびん、0.001gの精度、100g最小容量。
・図4を参照して、膨潤率試験装置910は、負荷下吸収(AUL)試験方法で上述した、シリンダ920、ピストン930及び重り990を備えるAULアッセンブリ925を含む。ただし、AUL試験では317の重りを用いたが、ここでは、100gの重りを用いる。この100gの重りは、米国ペンシルベニア州のウエストチェスター所在のVWRインターナショナル(VWR International)社から部品番号12727-141として入手可能である、またはその同等物が使用される。
・膨潤率試験装置910は、超吸水体サンプル950の膨潤中に吸上げられた侵襲液体を除去するのに使用されるAULチャンバも含む。このユニットは、要求吸収性テスタ(demand absorbency tester:DAT)と同様である。この試験装置は、米国マサチューセッツ州ダナーズ所在のM/Kシステムズ社(M/K Systems)から入手可能なGATS(gravimetric absorbency test system:重力測定吸収性試験装置)、並びに、非特許文献3に説明されている装置と同様である(この文献は、本明細書の記載と矛盾しない限りにおいて、引用することを以って本明細書の一部となす)。直径2.5cmの領域内に限定して設けられたポートを有する、ポーテッドディスク935も利用される。
・液体層−ペトリ皿、プラスチック重り皿または過剰な液体を保持できる同様のもの。
・ステンレス鋼ワイヤまたは例えば8メッシュプラスチックスクリーンなどの大きな領域を有するプラスチックメッシュスクリーン。
・真空源‐吸引装置、ハウス真空ラインまたは真空ポンプ。
・側枝付きフラスコ960(図4)、フラスコの上部には、ゴム栓946及びチューブ955が嵌められている。
・ゴムまたはプラスチック製チューブ970(図4)。
・1秒間間隔で120分間計測可能なタイマー。
・ペーパータオルまたはティッシュ。
・静電気防止布。例えば、米国ニュージャージー州ワイコフ所在のイルフォードフォト社(Ilford Photo Corp.)から部品番号203547として入手可能なものまたは同等物。
・バルク超吸水性材料を示す粒径の分布が、試験に使用されるべきである。このことは、典型的には、回転分割機(spinning riffler)の使用を必要とする。適切な分割機は、英国ロンドン所在のマイクロスケール社(Microscal Limited)から市販されているModel SR 1Bである。分割機には、各個別のサンプル重量が0.160+/−0.005gmなどの十分な量の超吸水性材料を入れるべきである。
・真空装置。AULチャンバ940と側枝付きフラスコ960の上部にはめ込まれたチューブとを接続するのにチューブ970を使用する。真空源(図示せず)とフラスコ960の側枝980との間を接続するのにチューブ970を使用する。この側枝付きフラスコ960の目的は、サンプルから除去されたあらゆる液体を、真空装置に入る前に閉じ込めることである。側枝付きフラスコ960の安定性を高めるために、リングスタンドまたはリングスタンドと同様の固定器具にフラスコを取り付けることが望ましい。
・液体槽。液体槽皿(図示せず)の底部に、ワイヤメッシュ(図示せず)又は同様の大型メッシュプラスチックスクリーンを配置する。前記スクリーンは、AULアッセンブリ925を前記液体槽の上から下まで保持するように配置し、液体のサンプルへの自由なアクセスを可能にする。
