Description

BESCHREIBUNG DES STANDES DER TECHNIKDESCRIPTION OF THE PRIOR ART

Aus Gründen des Umweltschutzes wie auch der Verbesserung der Oberflächengüte ist die Beliebtheit von Mehrkomponentenfarben und anderen Mehrkomponentenmaterialen in den letzten Jahren rasant gestiegen. Verschiedene Hersteller bieten Ausrüstung zum Messen und Mischen der mehreren Komponenten für die Anwendung auf verschiedenen Trägermaterialien an. Insbesondere stellen wasserbasierende Materialien ein besonderes Problem für das Mischen und Verbinden der Materialien dar. Während Geräte zum Mischen solcher Materialien wie die Graco PRECISIONMIX© Mehrkomponentenausrüstung in Industriekreisen bereits weitreichende Akzeptanz gefunden haben, bestehen manche immer noch auf dem Erreichen der perfekten Mischung. Ein Düsendispersionsgerät, hergestellt von Bayer, kann erwiesenermaßen die Mischung solcher Materialen erreichen, das Gerät ist jedoch kompliziert und mit einer relativ schwierigen Spülung versehen.For reasons of environmental protection as well as the improvement of the surface quality, the popularity of multicomponent paints and other multicomponent materials has risen rapidly in recent years. Various manufacturers offer equipment for measuring and mixing the multiple components for use on different substrates. In particular, make water-based materials, a particular problem for the mixing and joining the materials. While equipment for mixing such materials as have already found multi-component equipment in industry circles wide acceptance Graco PrecisionMix ©, some still exist on achieving the perfect blend. A nozzle disperser manufactured by Bayer has been shown to accomplish the mixing of such materials, but the apparatus is complicated and relatively difficult to purge.

BESCHREIBUNG DER ERFINDUNGDESCRIPTION THE INVENTION

Ziel der vorliegenden Erfindung ist es, einen Mischer zu bieten, der in der Lage ist, homogen gemischte Materialien selbst aus schwer mischbaren Komponenten herzustellen. Um dies zu erreichen setzen typische sequentielle Dosiergeräte wie der zuvor erwähnte PRECISIONMIX© einen Integrator, gefolgt von einem statischen Mischer ein, um diesen Mischvorgang vorzunehmen. In der vorliegenden Erfindung ist der Ausgang des statischen Mischers mit einer konventionellen Airless-Spritzdüse verbunden, welche sich in der Reihe an der Verbindung zur Spritzpistole oder einem anderen Auftragungsgerät befindet. Dabei wird eine Düsengröße verwendet, die einen Druckverlust durch die Airless-Spritzdüse von 10–30 bar aufrecht halten kann, was für einen angemessenen Druckverlust sorgt. Ein Beispiel hierfür wäre die Verwendung einer 0,8 mm Düse in einer 5 mm Flüssigstoffleitung.The aim of the present invention is to provide a mixer capable of producing homogeneously mixed materials even from difficult-to-mix components. To do that put typical sequential dosing as previously PrecisionMix © one mentioned an integrator followed by a static mixer to make this mixing process. In the present invention, the outlet of the static mixer is connected to a conventional airless spray nozzle, which is in line with the connection to the spray gun or other applicator. It uses a nozzle size that can maintain a pressure drop through the airless spray nozzle of 10-30 bar, which ensures a reasonable pressure drop. An example of this would be the use of a 0.8 mm nozzle in a 5 mm fluid line.

BESCHREIBUNG DER BEVORZUGTEN AUSFÜHRUNGSFORMDESCRIPTION THE PREFERRED EMBODIMENT

Die vorliegende Erfindung 10 umfasst eine Mehrkomponentenmischmaschine 12, mit einem Integrator 14 gefolgt von einem statischen Mischer 16. Der Ausgang 16a des statischen Mischers 16 ist an eine Spritzdüse 18 angeschlossen, welche eine konventionelle Airless-Spritzdüse sein kann, wie etwa eine von der Firma Graco Inc. oder einem beliebigen anderen Hersteller hergestellte Düse. Die Airless-Spritzdüse 18 ist wiederum an eine Flüssigstoffleitung 20 angeschlossen, welche wiederum mit einem Auftragungsgerät 22, wie etwa einer Spritzpistole oder einem ähnlichen Gerät, verbunden ist.The present invention 10 includes a multi-component mixing machine 12 , with an integrator 14 followed by a static mixer 16 , The exit 16a static mixer 16 is to a spray nozzle 18 which may be a conventional airless spray nozzle, such as a nozzle made by Graco Inc. or any other manufacturer. The airless spray nozzle 18 is in turn to a liquid line 20 connected, which in turn with an application device 22 , such as a spray gun or similar device.

Es ist vorgesehen, dass verschiedene Änderungen und Modifikationen an dem Mischer für Mehrkomponentenmateriale vorgenommen werden können, ohne dass damit der Umfang dieses Patents, wie in den folgenden Patentansprüchen beschrieben, verlassen wird.It is provided that various changes and modifications at the mixer for Multi-component materials can be made without affecting the scope of this patent as described in the following claims becomes.
