Description
12gの活性炭(Yuhuan activated carbon社製ヤシガラ活性炭、平均粒径15μm、表面積2000m2/g)及び38gの水を高速ミキサーに加え、速度1000rpmで30秒間室温で混合した。
6gの活性炭(Yuhuan activated carbon社製ヤシガラ活性炭、平均粒径15μm、表面積2000m2/g)、2.1gの陰イオン交換樹脂(Tianjin Nankai Resin Factory製、強塩基性陰イオン交換体201X7、使用前に粒径約50μmに粉砕、含水量40%)及び20gの水を高速ミキサーに加え、速度1000rpmで30秒間室温で混合した。
6gの活性炭(Yuhuan activated carbon社製ヤシガラ活性炭、平均粒径15μm、表面積2000m2/g)、2.1gの陽イオン交換樹脂(Tianjin Nankai Resin Factory製強酸性陽イオン交換体001X7、使用前に粒径約50μmに粉砕、含水量40%)及び20gの水を高速ミキサーに加え、速度1000rpmで30秒間室温で混合した。
12gの活性炭(Yuhuan activated carbon社製ヤシガラ活性炭、平均粒径15μm、表面積2000m2/g)及び35gのエタノールを高速ミキサーに加え、速度1000rpmで30秒間室温で混合した。
12gの活性炭(Yuhuan activated carbon社製ヤシガラ活性炭、平均粒径15μm、表面積2000m2/g)、38gの水及び1.2gのPTFEを秤量した。高速ミキサーでこれらの材料を速度1000rpmで60秒間室温で混合した。スラリーは、かなりの水を含んでいるので、スラリーから水を分離せずにそのままローラーでカレンダー加工するのは容易ではない。30分間放置すると、水がしみ出してペーストとなり、カレンダー加工に使用することができる。或いは、ろ紙でろ過してペーストにした後に、ペーストをローラーでのカレンダー加工に使用することができる。
