Description
ZSM−5(シリカ/アルミナのモル比約50/1)80重量部、Ultrasil VN3SP固体10重量部、Ludox固体10重量部、および水48重量部を、12wt%水酸化カリウム水溶液250重量部と混合して、乾燥ベースで、全固体含含有量を基準として固体含有量58重量%およびKOH含有量3wt%を有する混合物が製造された。混合は、Eirichミキサーで行なわれ、槽回転および羽回転はいずれも、装置のそれらそれぞれの高い設定値にあった。混合を、押出し成形可能な混合物が得られるまで続けた。
実施例1を、繰り返した。しかし、水酸化カリウム溶液を、12wt%水酸化ナトリウム水溶液250重量部で置換えた。そのために、NaOHは、混合物中に、乾燥ベースで、混合物の全固体含有量を基準として3wt%の量で存在した。再度、結果を表1に要約する。
Ultrasil VN3SP、Avicel(微結晶セルロース押出し成形助剤)、12wt%水酸化カリウム水溶液、および水を組合わせて、固体含有量47wt%を有する水性混合物が製造された。固体は、乾燥ベースで、Ultrasil VN3SPシリカ固体100部、Avicel 20部、およびKOH2部から構成された。混合は、Eirichミキサーで行われ、槽回転および羽回転はいずれも、装置のそれらそれぞれの高い設定値にあった。混合を、押出し成形可能な混合物が得られるまで続けた。
実施例3の方法を、繰り返した。しかし、固体含有量45wt%を有する初期水性混合物を用いた。固体は、乾燥ベースで、Ultrasil VN3SPシリカ固体100部、Avicel 20部、KOH4部から構成された。得られた成形体の特性を、表2に要約する。
実施例4の方法を、再度、繰り返した。しかし、固体含有量42wt%を有する初期水性混合物を用いた。得られた成形体の特性を、表2に要約する。
Ultrasil VN3SPシリカ、12wt%水酸化カリウム水溶液、および水を、組合わせて、固体含有量47wt%を有する水性混合物が製造された。固体は、乾燥ベースで、Ultrasil VN3SPシリカ固体100部、およびKOH4部から構成された。混合は、Eirichミキサーで行われ、槽回転および羽回転はいずれも、装置のそれらそれぞれの高い設定値にあった。混合を、押出し成形可能な混合物が得られるまで続けた。
実施例6の方法を、繰り返した。しかし、固体含有量45wt%を有する初期水性混合物を用いた。得られた成形体の特性を、表2に要約する。
