Description
[実施例1]
Alpharetta, Gaにオフィスを持つArch Chemicals, Inc.から入手可能な市販のTURBO SHOCK(登録商標)次亜塩素酸カルシウム組成物を、水酸化カルシウム粉末(石灰)と2本ロールミルにおいて乾式ブレンドし、均質な混合物を表1に示す量で形成する。次亜塩素酸カルシウム組成物は、約3%の水酸化カルシウム(石灰)を含有していた。次に、得られたブレンドを、15トン及び5秒保圧時間で製造された15グラムの錠剤へと打錠した。試料2〜6は本発明の範囲内であり、試料1は先行技術の一般的教示内である。比較目的で、2つの比較例、20%の水酸化バリウム又は20%の酸化亜鉛をそれぞれ含有する試料7及び8もまた、TURBO SHOCK(登録商標)次亜塩素酸カルシウム組成物とブレンドした。錠剤の初期重量、直径、厚さを表1に報告する。
次亜塩素酸カルシウム(TURBO SHOCK(登録商標))及び水酸化カルシウム粉末の75/25及び80/20(重量%)ブレンドを調製するために、Vブレンダーを使用した。上のブレンドの錠剤を調製するため、Bipelパフォーマー(performer)70トンプレスを5秒の保圧時間で使用した。錠剤はそれぞれおよそ200グラムだった。錠剤を10,000ガロンのプールのスキマー内に置き、その溶解速度を確認した。プールのポンプを、1日当たり8時間作動させた。錠剤を24時間ごとにスキマーから除去し、秤量した。錠剤3及び4は、研究期間の間の各錠剤の重量を示す。表3の錠剤を同じスキマーに配置し、表4の錠剤を異なるスキマーにまとめて配置した。表3及び表4は、各錠剤の溶解速度/時間を要約する。
ブレンドの重量に対して、約3.5%の石灰を含有する次亜塩素酸カルシウムと5.5%の石灰及び9.0%の石灰とのブレンドを調製するために、ロールミルを使用した。得られたブレンドはそれぞれ、8.8重量%の総量の石灰及び12.2重量%の総量の石灰を含有していた。2インチ(5.08センチメートル)のダイを備えるプレスを使用して、約100グラムの錠剤を調製した。ブレンドをダイ内に配置し、18トンの圧力を30秒の保圧時間で適用した。錠剤の重量を記録し、表5に示す。錠剤を100ガロンのタンクのスキマー内に置き、水を毎分20ガロンの速度で循環させながら、その溶解速度を確認した。各試料錠剤をスキマーから除去し、ペーパータオルを軽く当てて乾燥させ、秤量した。秤量したら、継続試験のため試料をスキマー内に戻した。錠剤重量は表5に示すとおりだった。
