Abstract

The subject of the invention is a method of destroying harmful animals in dead wood. The state of the art is to kill wood pests in furniture by placing them in heat chambers for a number of hours. The disadvantage of this method is the relatively long duration of its implementation and the possible formation of dryness cracks in the furniture wood. The aim of the invention is to eliminate this risk and to shorten the duration of the method. This aim is achieved by killing the wood pests by irradiation with high frequency in the wider sense, in particular by using microwaves. As a result, water is extracted from the wood pests; they dry out. The advantage of this solution is the very short (approximately 15-30 seconds) irradiation period during which the wood and any coatings are not changed. Irradiation intervals are favourable in the case of Boulle furniture and the like.

Description

Gegenstand der Erfindung ist ein Verfahren zur Vernichtung schäd­ licher Tiere wie Würmer und ähnlicher Schädlinge in totem Holz, insbesondere von Möbeln, Bilderrahmen und Skulpturen sowie Fach­ werken, Dachstühlen, Baumstämmen und -rinden, die Borkenkäfer enthalten.The invention relates to a method for damaging destruction animals like worms and similar pests in dead wood, especially of furniture, picture frames and sculptures as well as subject plants, roof trusses, tree trunks and barks, the bark beetles contain.

Stand der Technik ist das Töten von Holzschädlingen in Möbeln durch deren mehrstündiges Verweilen in Wärmekammern. Nachteil dieses Verfahrens ist die relativ lange Dauer seiner Durchführung und die eventuelle Bildung von Trockenrissen im Möbelholz.State of the art is the killing of wood pests in furniture by staying in warm chambers for several hours. The disadvantage of this method is the relatively long duration of it Implementation and the possible formation of dry cracks in the Furniture wood.

Aufgabe der Erfindung ist die Abwendung dieser Gefahr und die Verkürzung der Verfahrensdauer.The object of the invention is to avert this danger and Shortening the process time.

Lösung dieser Aufgabe ist das Töten der Holzschädlinge durch Be­ strahlung mit Hochfrequenz im weiteren Sinne, insbesondere durch Verwendung von Mikrowellen. Dadurch wird den Holzschädlingen Was­ ser entzogen; sie trocknen aus.This task is solved by killing the wood pests by Be radiation with high frequency in the broader sense, in particular through Use of microwaves. This is what the wood pests withdrawn; they dry up.

Vorteil dieser Lösung ist die sehr kurze Bestrahlungsdauer, während der sich das Holz nicht verändert; auch Schellackpoli­ turen, Petersburger Möbellacke und Spirituslacke werden nicht beschädigt.The advantage of this solution is the very short exposure time, during which the wood does not change; also shellac poli doors, Petersburg furniture varnishes and spirit varnishes are not damaged.

Vorzugsweise ist vorgesehen, daß größenordnungsmäßig zehn Sekun­ den, insbesondere fünfzehn bis dreißig Sekunden lang bestrahlt wird.It is preferably provided that the order of magnitude is ten seconds irradiated, especially fifteen to thirty seconds becomes.

Bei Boulle-Möbeln und vergoldeten Möbeln wird vorteilhalfterweise mit Intervallen bestrahlt.Boulle furniture and gilded furniture are advantageously used irradiated with intervals.

Vor Bestrahlung antiker Möbel müssen Beschlagteile entfernt wer­ den. Eingeschlagene Nägel oder kleine Eisenteile führen nicht zu Verbrennungen an der Oberfläche.Hardware components must be removed before irradiating antique furniture the. Hammered nails or small iron parts do not lead to Burns on the surface.
