Es ist nun Aufgabe der Erfindung, ein elektrisches Heizelement für einen Infrarotstrahler beziehungsweise einen Infrarotstrahler bereitzustellen, dessen abgestrahlte Wellenlänge auf den jeweiligen Anwendungsfall eingestellt werden kann.It Now is an object of the invention to provide an electric heating element for a To provide infrared radiator or an infrared radiator whose radiated wavelength can be adjusted to the particular application.
Die Aufgabe wird dadurch gelöst, dass die Beschichtung auf dem Grundkörper eines elektrisch leitenden Heizleiters aus mindestens einem Oxid mindestens eines Metalles aus der Gruppe der Lanthaniden gebildet ist. Eine derartige Beschichtung ermöglicht es, das Emissionsspektrum des Grundkörpers, das dieser in unbeschichteter Form bei direkter elektrischer Beheizung aufweist, zu verändern und durch eine geeignete Auswahl der Materialien für die Beschichtung an die jeweiligen Anforderungen anzupassen.The Task is solved by that the coating on the body of an electrically conductive Heat conductor of at least one oxide of at least one metal is formed from the group of lanthanides. Such a coating allows it, the emission spectrum of the main body, this in uncoated Form in direct electrical heating has to change and through a suitable selection of the materials for the coating to the respective To adapt requirements.
Dabei hat es sich bewährt, wenn das Oxid zumindest teilweise in den Grundkörper eindiffundiert ist.there has it proven when the oxide is at least partially diffused into the body.
Der Grundkörper ist Idealerweise aus einem Metall, einer Metall-Legierung oder einem Kohlenstoffmaterial gebildet. Besonders sind dabei Wolfram oder ein Carbonfasern aufweisendes Carbonband geeignet.Of the body is ideally made of a metal, a metal alloy or a Carbon material formed. Especially are tungsten or a carbon fiber having carbon band suitable.
Es hat sich bewährt, wenn die Beschichtung aus Er2O3 und/oder Yb2O3 und/oder Ho2O3 und/oder Nd2O3 gebildet ist.It has proven useful if the coating consists of Er 2 O 3 and / or Yb 2 O 3 and / or Ho 2 O 3 and / or Nd 2 O 3 .
Der Grundkörper kann jede erdenkliche Form annehmen. Besonders bevorzugt ist dabei allerdings, wenn der Grundkörper als Wendel ausgestaltet ist.Of the body can take any shape. Particular preference is given however, if the main body is designed as a helix.
Für einen Infrarotstrahler wird das elektrische Heizelement gasdicht in einem Schutzrohr aus Kieselglas angeordnet Das Schutzrohr ist dabei vorzugsweise mit mindestens einem Edelgas befüllt oder evakuiert.For one Infrared heater, the electric heating element is gas-tight in one Protective tube made of silica glass The protective tube is preferably filled with at least one inert gas or evacuated.
Die Verwendung eines derartigen Infrarotstrahlers zur Druckfarbentrocknung und/oder -härtung oder zur Umformung von Kunststoffen ist ideal.The Use of such an infrared radiator for printing ink drying and / or curing or for forming plastics is ideal.
Nachfolgend wird die Herstellung von erfindungsgemäßen elektrischen Heizelements beispielhaft erläutert. Zur Beschichtung des Grundkörpers eignet sich beispielsweise ein Sol-Gel-Prozess, ein Aufsintern oder auch Aufdampfen hervorragend.following is the production of electrical heating element according to the invention exemplified. Suitable for coating the base body For example, a sol-gel process, a sintering or vapor deposition excellent.
