Description
気及び水の使用量を抑えた方法を提供することにある。更に、現行の技術では製造が不可能か又は特殊な抗酸化剤を添加する場合のみ可能である、温度に影響されやすい混合物を製造できるようにすることも目的としている。新たな処理方法は、エネルギー効率が良く、環境に優しく且つ柔軟性のある工程を創成することを目的としている。
合物の最高温度が、製品の損傷温度に達するか超える場合にのみ制御される。
は明らかに低くなり、これにより拡散を促進するストリッッピング効果が生ずる。
直接に混練器に送られる。
高分子溶液又は懸濁液、特にエラストマー溶液又は懸濁液から溶剤が取去られるので、沸騰状態が逆になることもある。固体含有量が増加して臨界量を超えると、製品が強く泡立って泡が熱交換面を濡らして熱交換を阻害するので、熱交換係数は低下する。極めて希釈された溶液では、高分子溶液表面への気泡の対流は阻害されない。固体含有物は気泡の動きを阻害する。泡としての気泡は、安定しているので、泡を機械的に破壊する必要がある。
