二軸混練押出機HYPERKTX®の混練技術

摘要

最近の二軸混練押出機は高速化が進み，生産rn性が著しく向上した。これに伴って，低温・高分散型のrn混練セグメントのニーズが高まっている。一般的に，低rn温混練にはロータセグメントが適しているが，当社ではrn最近，ロータの漏練機構にVCMT（Various ClearancernMixing Technology）と称する新しいメカニズムを開発rnし，生産性と混練品質の向上を図っている。%Twin-screw extruder "HYPERKTX" has not only conventional kneading disks but also special rotors such as 3-tips rotor and various clearance mixing technology (VMCT) rotor which have features to solve problems of heat generation and mixing performance for polymer and elastomer. Applications of those special rotors for continuing user demands such as higher productivity and better mixture quality are reported in this paper. Developments to improve the reliability of machines are also introduced.
