Description

Glasrohr mit strahlungsabsorbierender alterungsbeständiger BeschichtungGlass tube with radiation-absorbing, age-resistant coating

Die vorliegende Erfindung betrifft ein Glasrohr mit strahlungsabsorbierender alterungsbeständiger Schicht und ein Verfahren zu dessen Herstellung.The present invention relates to a glass tube with a radiation-absorbing, aging-resistant layer and a method for its production.

Aus „Neue Vakuumröhren für Sonnenkollektoren" von Martin Brunotte, Norbert Dischinger, Gottfried Haas in Neuentwicklungen, 1999, Heft 3" ist der Aufbau eines Absorberrohres für Vakuumröhren bekannt. Auf das Glas wird zunächst eine IR-reflektierende Schicht aus metallischen Aluminium gesputtert. Als nächste Schicht wird eine Aluminiumnitrid-Schicht mit Aluminium-Einlagerungen gesputtert, dann wird eine Aluminiumoxid-Schicht mit Aluminium-Einlagerungen gesputtert, und schließlich wird eine Aluminiumoxid Deckschicht gesputtert. Die herkömmlich hergestellten Absorberrohren zeigen deutliche Farbveränderungen als Folge der schnellen Alterung. Die Alterung hat die Herabsetzung der Leistungsfähigkeit des Kollektors zur Folge.The structure of an absorber tube for vacuum tubes is known from "New vacuum tubes for solar collectors" by Martin Brunotte, Norbert Dischinger, Gottfried Haas in New Developments, 1999, Issue 3. An IR-reflecting layer of metallic aluminum is first sputtered onto the glass. As the next layer, an aluminum nitride layer with aluminum deposits is sputtered, then an aluminum oxide layer with aluminum deposits is sputtered, and finally an aluminum oxide cover layer is sputtered. The conventionally manufactured absorber tubes show significant color changes as a result of the rapid aging. Aging reduces the performance of the collector.

Die Aufgabe der Erfindung wird durch ein Glasrohr mit strahlungsabsorbierender alterungsbeständiger Schicht gelöst, die a) eine erste IR-reflektierende Schicht auf dem Glas enthält, b) eine zweite Schicht, die Aluminium und Aluminiumnitrid enthält, c) eine dritte Schicht, die Aluminium und Aluminiumoxid enthält, wobei beim Auftragen der dritten Schicht 02 mit einem Volumenstrom von 40 ncm3/min bis 60 ncm3/min eingeleitet worden ist, und d) eine vierte Schicht, die Aluminiumoxid enthält.The object of the invention is achieved by a glass tube with a radiation-absorbing, aging-resistant layer which contains a) a first IR-reflecting layer on the glass, b) a second layer which contains aluminum and aluminum nitride, c) a third layer which contains aluminum and aluminum oxide contains, with the third layer 0 2 having been introduced with a volume flow of 40 ncm 3 / min to 60 ncm 3 / min, and d) a fourth layer which contains aluminum oxide.

Bei dem erfindungsgemäßen Glasrohr wurde eine Beschichtung erhalten, die keine relevanten Farbveränderungen zeigt. Die ausbleibende Farbveränderung deutet auf äußerst geringe Alterung hin. Das wird erfindungsgemäß durch Einleiten eines Volumenstroms von 40 ncm3/min bis 60 ncm3 02 beim Auftragen der dritten Schicht erreicht (ncm3 = cm3 in Normzustand). Eine bevorzugte Ausgestaltung der Erfindung ist ein Glasrohr mit strahlungsabsorbierender alterungsbeständiger Beschichtung, wobei beim Auftragen der dritten Schicht 02 mit einem Volumenstrom von mit 45 ncm3/min bis 60 ncm3/min eingeleitet wird. Mit diesem Volumenstrom werden sehr gute Ergebnisse erzielt.In the glass tube according to the invention, a coating was obtained which showed no relevant color changes. The lack of color change indicates extremely low aging. This is achieved according to the invention by introducing a volume flow of 40 ncm 3 / min to 60 ncm 3 0 2 when applying the third layer (ncm 3 = cm 3 in the normal state). A preferred embodiment of the invention is a glass tube with a radiation-absorbing, aging-resistant coating, with 0 2 being introduced with a volume flow of 45 ncm 3 / min to 60 ncm 3 / min when the third layer is applied. Very good results are achieved with this volume flow.

Eine bevorzugte Ausgestaltung der Erfindung ist ein Glasrohr mit strahlungsabsorbierender alterungsbeständiger Beschichtung, wobei beim Auftragen der dritten Schicht 02 mit einem Volumenstrom von mit 50 ncm3/min bis 60 ncm3/min eingeleitet wird. Mit diesem Volumenstrom werden sehr gute Ergebnisse erzielt.A preferred embodiment of the invention is a glass tube with a radiation-absorbing, age-resistant coating, with 0 2 being introduced at a volume flow of 50 ncm 3 / min to 60 ncm 3 / min when the third layer is applied.

Eine bevorzugte Ausgestaltung der Erfindung ist ein Glasrohr mit strahlungsabsorbierender alterungsbeständiger Beschichtung, wobei die vierte Schicht eine Schichtdicke von 80 nm bis 120 nm aufweist.A preferred embodiment of the invention is a glass tube with a radiation-absorbing, aging-resistant coating, the fourth layer having a layer thickness of 80 nm to 120 nm.

Erfindungsgemäß ist ein Verfahren zur Herstellung eines Glasrohres mit strahlungsabsorbierender alterungsbeständiger Beschichtung vorgesehen, wobei eine erste IR-reflektierende Schicht auf dem Glas aufgebracht wird, eine zweite Schicht, die Aluminium und Aluminiumnitrid enthält, aufgebracht wird, eine dritte Schicht, die Aluminium und Aluminiumoxid enthält, aufgebracht wird, wobei beim Auftragen der dritten Schicht 02 mit einem Volumenstrom von mit 40 ncrn3/min bis 60 ncm3/min eingeleitet wird, und eine vierte Schicht, die Aluminiumoxid enthält, aufgebracht wird.According to the invention, a method for producing a glass tube with a radiation-absorbing, age-resistant coating is provided, a first IR-reflecting layer being applied to the glass, a second layer containing aluminum and aluminum nitride being applied, a third layer containing aluminum and aluminum oxide, is applied, during the application of the third layer 0 2 with a volume flow of 40 ncrn 3 / min to 60 ncm 3 / min, and a fourth layer containing aluminum oxide is applied.

Erfindungsgemäß ist die Verwendung eines Glasrohres mit strahlungsabsorbierender alterungsbeständiger Beschichtung zur Herstellung von Vakuum- Röhrenkollektoren vorgesehen.

Es wurden keine relevante Farbveränderungen beobachtet.A coated glass tube was measured on the optical spectrometer for its reflection distribution (curve (a)). Then the absorber tube was subjected to accelerated aging. The acceleration was achieved when the absorber tube was in the collector and heated to 240 ° C for 100 hours has been. The reflection distribution was then measured again (curve (b)). No relevant color changes were observed.

VergleichsbeispielComparative example

Das Vergleichsbeispiel wurde wie das Beispiel durchgeführt, jedoch mit dem Unterschied, dass 5 Sekunden 02 mit einem Volumenstrom von 70 ncm3/min zur Herstellung der dritten Schicht eingeleitet wurde. Die gemessene Reflektionsverteilung nach der beschleunigten Alterung ergab eine deutliche Farbveränderung. Die Farbveränderung ist eine Folge der Alterung (Kurve (d)). Die Alterung hat die Herabsetzung der Leistungsfähigkeit des Kollektors zur Folge. The comparative example was carried out as the example, but with the difference that 5 seconds 0 2 with a volume flow of 70 ncm 3 / min was introduced to produce the third layer. The measured reflection distribution after accelerated aging showed a clear color change. The color change is a result of aging (curve (d)). Aging reduces the performance of the collector.
