VORRICHTUNG ZUM DOSIERTEN ZUFÜHREN DER EINZELKOMPONENTEN VON FLÜSSIGEM MEHRKOMPONENTEN-KUNSTSTOFF AN EINEN MISCHKOPF

摘要

Metering is carried out directly from component containers consisting of upright pressure cylinders with removable lids. The necessary pressure is maintained in each case by a displacer piston which can be moved upwards in a controlled manner. The pressure can be built up by the displacer piston or by an additional pressure piston. In many applications, a disposable bag can be inserted in the pressure cylinder. The valves of the mixing head are preferably combined with a common drive plate for the valve tappets to form a valve assembly protected by softener. In one configuration for a dynamic mixer, the mixing tool is laminar so that it can be rapidly cleaned.
