Abstract

Die Bestrahlungseinrichtung zum Trocken und/oder Härten von Farben, Lacken und ähnlichen Beschichtungen (13,14) weist mindestens einen UV-Hochleistungsstrahler mit einem mit Füllgas gefülltem Entladungsraum (3) auf. Das darin enthaltene Füllgas sendet unter Einfluss von stillen elektrischen Entladungen Strahlung aus. Der Entladungsraum (3) ist von Wänden (1,2) begrenzt, wobei mindestens eine Wand aus dielektrischem Material besteht und für die im Entladungsraum (3) erzeugt Strahlung durchlässig ist. Ein Elektrodenpaar (4,5) mit einer an die beiden Elektroden angeschlossenen Wechselstromquelle (10) dient zur Speisung der Entladung. Der Behandlungsraum (6) grenzt unmittelbar an das Dielektrikum (1,2) an. Die Elektroden (4,5) sind vom dem unmittelbar benachbarten Dielektrikum beabstandet. Die Ankopplung der elektrischen Energie von den Elektroden in den Entladungsraum erfolgt im wesentlichen kapazitiv. Auf diese Weise bilden sich neben den Entladungen im eigentlichen Entladungsraum (3), die für die Erzeugung von UV- bzw. VUV-Strahlung verantwortlich sind, auch in den Behandlungsräumen (6,7) elektrische Entladungen aus, die neben der im Entladungsraum (3) entstehenden Strahlung zusätzlich auf die besagten Beschichtungen katalytisch einwirken und die Trocknung/Härtung der Beschichtung (13,14) wesentlich beschleunigen. The irradiation device for drying and / or curing paints, lacquers and similar coatings (13, 14) has at least one UV high-power lamp with a discharge space (3) filled with filling gas. The filling gas contained therein emits radiation under the influence of silent electrical discharges. The discharge space (3) is delimited by walls (1, 2), at least one wall being made of dielectric material and permeable to the radiation generated in the discharge space (3). A pair of electrodes (4, 5) with an alternating current source (10) connected to the two electrodes is used to feed the discharge. The treatment room (6) borders directly on the dielectric (1, 2). The electrodes (4, 5) are spaced apart from the immediately adjacent dielectric. The coupling of the electrical energy from the electrodes into the discharge space is essentially capacitive. In this way, in addition to the discharges in the actual discharge space (3), which are responsible for the generation of UV or VUV radiation, electrical discharges also form in the treatment rooms (6, 7), which in addition to those in the discharge space (3 ) resulting radiation additionally act catalytically on the said coatings and significantly accelerate the drying / hardening of the coating (13, 14).
