Module forming part of a static mixer arrangement for a plastically flowable material to be mixed having a critical dwell time

摘要

The module is a part of a static mixer which is provided for a plastic, flowable, composition to be mixed which is critical with respect to the dwell time. The apparatus comprises a tubular housing in which arms are arranged. The arms are inclined with respect to the longitudinal axis of the housing; they cross each other substantially on a straight line perpendicular to the longitudinal axis. The module comprises a sleeve which can be pushed into the housing. The inner wall of the apparatus which conducts the composition being mixed is formed by the inner sides of the sleeves. The arms are formed in the shape of rods each having a tip directed opposite to the direction of movement of the mixing mass and a base fastened to the inner side of the sleeve. Each tip forms an intermediate space with respect to the inner wall of the apparatus.
