Abstract

The procedure for the drying of liquid applied coatings on components and bodies allows a consistency to be reached which corresponds to the desired aim, to the temporary protection of components and bodies, and in a desired measure. The film after a short time is mechanically manipulable by quick skinning of the surface to be protected, and in consequence easily withdrawable. During this process the object being protected in neither chemically nor mechanically so impaired that a loss of quality ensues.

Description

AA

Die durch Luft oder Strahlung erwärmten Bauteile und oder Karosserien (auf 30/120°C temperiert), werden manuell und oder maschinell durch besprühen, bepinseln, bespachteln mit dem flüssigen Schutzauftrag versehen, das vorherige Temperieren, führt zu einer erwünschten Verhautung des Schutzauftrages an der Oberfläche des zu schützenden Bauteils (u.o. Karroserie), die Oberfläche des Schutzauftrages bleibt weitestgehend ungebunden und erleichtert den im folgenden stattfindenden Entzug der Feuchtigkeit.The components heated by air or radiation and or bodies (at 30/120 ° C tempered), are manually and or mechanically sprayed, brushed, fill with the liquid protective coating provided, the previous tempering leads to a desired one Skin of the protective order on the surface of the component to be protected (including the bodywork), the surface the protection order remains largely unattached and relieved the subsequent removal of moisture.

Im weiteren werden die Bauteile u. o. Karosserien einem Umlufttrockner zugeführt, der durch eine mehrstufige Luftbehandlung die Prozessumluft wie folgt behandelt. Die Prozessluft wird bis zum Taupunkt abkühlt und entfeuchtet, anschließend werden an einem Labyrinthabscheider, kondensierte aber durch den Luftstrom mitgerissene Wassertröpfchen ableitet, um die erforderliche absolute Feuchte zu erreichen, wird bei Bedarf die an diesem Punkt des Prozesses die feuchte kalte Luft über einen weiteren Luftkühler geführt, die enthaltene Feuchtigkeit gefroren und auf den benötigten absoluten Feuchtegehalt getrocknet. Dieser Prozess kann aus Redundanzgründen über wechselseitig arbeitende Kühler erfolgen. Im weiteren wird die Prozessluft über einen Wärmetauscher geführt und erwärmt, so dass die zum trocknen der Folie erforderliche relative Feuchte erzielt wird (z.B.45°C/20%r.F.). Die wärmeaustauschenden Prozessschritte werden in einem kältetechnischen Kreisprozess miteinander durch eine Kälteanlage energetisch so gekoppelt, dass die aufzuwendende Energie nur der entspricht, die benötigt wird um den Kreisprozess in Gang zu halten. Die benötigten Anströmgeschwindigkeiten für die beschichteten Bauteile und oder Karosserien, werden mit einem Gebläse und einer entsprechenden Luftführung erzielt, die Anströmgeschwindigkeiten zwischen 0,5 und 3 m/s ermöglicht.Furthermore, the components u. o. Bodies supplied to a circulating air dryer, which is a multi-stage Air treatment treats the process air as follows. The process air is cooled down to the dew point and dehumidified, then are on a labyrinth separator, but condensed by the Air flow carries away entrained water droplets, to achieve the required absolute humidity, if necessary which at this point in the process the moist cold air over you another air cooler guided, the moisture contained is frozen and to the absolute required Moisture content dried. This process can be mutual for redundancy reasons working cooler respectively. The process air is then passed through a heat exchanger and heated so that the relative humidity required to dry the film is achieved (e.g. 45 ° C / 20% RH). The heat exchanging Process steps are carried out in a refrigeration cycle with each other through a refrigeration system energetically coupled so that the energy to be used is only the corresponds to that which is needed to keep the cycle going. The required flow velocities for the coated components and or bodies, with a blower and appropriate air flow achieved, the flow velocities between 0.5 and 3 m / s possible.

Die mit der Erfindung gewonnenen Vorteile bestehen insbesondere darin, dass der Trockenvorgang an die bei Industrieprozessen benötigten Taktzeiten angepasst werden kann und damit Stand- oder Wartezeiten bis zur Weiterbearbeitung entfallen.The obtained with the invention The main advantages are that the drying process begins that are required in industrial processes Cycle times can be adjusted and thus standstill or waiting times until further processing.

Eine Vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch zu B angegeben.An advantageous embodiment of the Invention is specified in the claim to B.

Weitere Anwendungen, auf die sich der oben beschriebene Prozess vorteilhaft auswirken kann und gleichfalls anwenden lässt, ist das Beschichten von thermisch vorbehandelte Bauteile und oder Karosserien, wie Füller auf vorbehandelte Karosserien, Lacke auf vorbehandelte Bauteile und oder Karosserien Auf eine Erläuterung der Erfindung anhand von Zeichnungen wird vorläufig verzichtet, wird jedoch falls dies als wünschenswert erachtet oder notwendig erscheint, umgehend nachgereicht.More applications that focus on the process described above can have an advantageous effect and likewise lets apply, is the coating of thermally pretreated components and or Bodies like fillers on pretreated bodies, paints on pretreated components and or bodies Based on an explanation of the invention of drawings becomes tentative waived, but if this is considered desirable or necessary, submitted immediately.
