Die Erfindung bezieht sich auf einen Ultraviolettstrahler, der mit einer Quarzglasumhüllung versehen ist, die die Strahlung mit einer Wellenlänge über 2100 A im wesentlichen unvermindert durchläßt, jedoch die Strahlung unter 1900 A, die für die Bildung von Ozon aus dem Luft-Sauerstoff verantwortlich ist, im wesentlichen vollständig absorbiert.The invention relates to an ultraviolet emitter which is provided with a quartz glass envelope which transmits the radiation with a wavelength above 2100 A essentially undiminished, however the radiation below 1900 A, which is responsible for the formation of ozone from the oxygen in the air, essentially completely absorbed.
Eine solche Quarzglasumhüllung ist bekannt. Zur Herstellung einer solchen Umhüllung wird Quarzglas verwendet, das kleine Mengen hitzebeständiger Oxyde, wie Zinkoxyd, in einer Menge unterhalb 0,1 °/o enthält. Auch ist es schon bekannt, eine Umhüllung zu verwenden, die aus zwei auf in der Glastechnik bekannte Weise deformierten und unter Erhitzung miteinander vereinigten Schichten besteht, deren Außenschicht aus einem solchen mit Zusätzen versehenen Quarzglas und deren Innenschicht aus Quarzglas ohne solche Zusätze besteht.Such a quartz glass envelope is known. Quartz glass is used to produce such a cover uses small amounts of refractory oxides, such as zinc oxide, in an amount below Contains 0.1%. It is also already known to use a casing made up of two in glass technology known way consists of deformed layers that are united with one another under heating, the outer layer of which is made from such a quartz glass provided with additives and the inner layer thereof Quartz glass is made without such additives.
In technologischer Beziehung sind solche Quarzglasumhüllungen jedoch für die Praxis weniger geeignet. Zusätze von fremden Oxyden zu einer Quarzglasschmelze liefern nicht leicht ein homogenes Produkt. Außerdem müssen dann immer dicke Schichten verwendet werden, da Quarzglas mit- größeren Konzentrationen an diesen Oxyden im wesentlichen nicht in glasartigem Zustand erhalten werden kann. Außerdem sind eine Anzahl der meist verwendbaren Oxyde bei der Schmelztemperatur des Quarzglases flüchtig, wodurch eine genaue Dosierung bei den in Betracht kommenden Konzentrationen in der Größenordnung von 0,1 °/o nicht möglich ist. Auch tritt mit manchen Oxyden ein erhöhter Angriff des Ofenmaterials auf.From a technological point of view, however, such quartz glass envelopes are less suitable for practical use. Additions of foreign oxides to a quartz glass melt do not easily produce a homogeneous product. In addition, thick layers must always be used, since quartz glass has higher concentrations on these oxides essentially cannot be obtained in a vitreous state. aside from that A number of the most commonly used oxides are volatile at the melting temperature of quartz glass, whereby an accurate dosage at the concentrations in question in the order of magnitude 0.1% is not possible. With some oxides there is also increased attack on the furnace material.
Es hat sich jedoch gezeigt, daß es zur Erhaltung der obigen Filterwirkung der Umhüllung nicht erforderlich ist, den Gehalt an fremden Ionen im Quarzglas zu haben, entweder durch den ganzen Gegenstand hindurch oder als eine Schicht solcher Ionen enthaltenden Quarzglases auf Quarzglas, das frei von fremden Ionen ist. Es hat sich ebenfalls gezeigt, daß Zinkoxyd, was die obige Füterwirkung anbetrifft, den günstigsten Transmissionsverlauf hat im Vergleich zu den übrigen an sich bekannten Oxyden.However, it has been shown that it is not necessary to maintain the above filter effect of the envelope is to have the content of foreign ions in the quartz glass, either through the whole Object through or as a layer of such ions-containing quartz glass on quartz glass, the is free from foreign ions. It has also been shown that zinc oxide, which has the above feeding effect is concerned, the most favorable transmission curve compared to the others known per se Oxides.
Der Ultraviolettstrahler weist eine Umhüllung auf, die aus Quarzglas ohne irgendeinen Zusatz besteht und eine Oxydschicht trägt, die erfindungsgemäß etwa 0,01 bis 1 μηι stark ist und aus SiO2 und ZnO mit einem Gehalt von 0,01 bis 0,5 mg Zinkoxyd je Quadratzentimeter besteht. Eine solche Schicht ist völlig farblos und für sichtbares Licht durchlässig.The ultraviolet emitter has a casing which consists of quartz glass without any additive and carries an oxide layer which, according to the invention, is about 0.01 to 1 μm thick and consists of SiO 2 and ZnO with a content of 0.01 to 0.5 mg zinc oxide each Square centimeters. Such a layer is completely colorless and permeable to visible light.
Die Zn O2-Si O2-Schicht kann außerdem noch andere Komponenten aufweisen, wie B2O3, Ca-ionen Quarzbrenner für UltraviolettstrahlungThe Zn O 2 -Si O 2 layer can also have other components, such as B 2 O 3 , Ca-ion quartz burner for ultraviolet radiation

Um eine solche Schicht auf einfache Weise auf Quarzglas aufzubringen, wird die Oberfläche mit einer Lösung einer Zink- und einer Siliziumverbindung benetzt, der gegebenenfalls noch andere Verbindungen hinzugefügt sind, wobei die Verbindungen durch Hydrolyse und/odec Pyrolyse in ihre Oxyde umwandelbar sind, und darauf auf eine Temperatur, bei der Hydrolyse und/oder Pyrolyse auftritt, erhitzt.

The temperature at which this heating occurs
geführt wird, beträgt etwa 400 bis 700 °. Bei der Herstellung eines Ultraviolettstrahlers kann man den Strahler mit einer Umhüllung aus normalem Quarzglas ohne Zusätze herstellen, die Umhüllung in dieser Phase zuerst mit einer diesbezüglichen Lösung bespritzen und den Strahler darauf z.B. einige Minuten brennen lassen. Die Temperatursteigerung, die die Umhüllung hierdurch erfährt, ist in der Regel genügend hoch, um die obige Hydrolyse- und/oder Pyrolysereaktion zu bewirken.is performed, is about 400 to 700 °. When making an ultraviolet emitter, one can use the Manufacture the radiator with a cover made of normal quartz glass without additives, the cover in this First spray the phase with a corresponding solution and then put the heater on for a few minutes, for example let it burn. The temperature increase that the envelope experiences as a result is usually sufficient high to cause the above hydrolysis and / or pyrolysis reaction.
Die obigen Zinkverbindungen, die durch Hydrolyse und/oder Pyrolyse Zinkoxyd liefern, sind z. B. Zinkchlorid, Zinknitrat oder Zinkacetat.The above zinc compounds which yield zinc oxide by hydrolysis and / or pyrolysis are, for. B. zinc chloride, Zinc nitrate or zinc acetate.

Ein rohrf örmiger Ultraviolettstrahler mit einer Umhüllung aus Quarzglas ohne irgendeinen Zusatz wird in einer Lösung getaucht, die je 400 ml Methanol, 6 g Zinkacetat und 40 g einer Lösung einer teilweise hydrolisierten Äthylsilikaüösung in einem Methanol-Wasser-Gemisch enthält, welche Lösung 7,5 g SiO2 je 100 ml aufweist, und dann langsam mit konstanter Geschwindigkeit gerade aus der Lösung herausgezogen. A tubular ultraviolet radiator with a cover made of quartz glass without any additive is immersed in a solution containing 400 ml of methanol, 6 g of zinc acetate and 40 g of a solution of a partially hydrolyzed ethylsilica solution in a methanol-water mixture, which solution contains 7.5 g SiO 2 per 100 ml, and then slowly pulled straight out of the solution at a constant speed.
Der Strahler wird dann mit der Spannungsquelle verbunden und einige Minuten im Betrieb gelassen.The heater is then connected to the voltage source and left in operation for a few minutes.
Dex ganze Vorgang wird dann noch dreimal wiederholt. Die erhaltene Schicht enthält etwa 0,1 mg ZnO je Quadratzentimeter Oberfläche. Die Transmission fur Strahlung von 2300 A und höher beträgt etwa 90%; diejenige für Strahlung unterhalb 1900A ist etwa 10%. Ozon kann jetzt sogar bei längerer Verwendung des Strahlers nicht nachgewiesen werden. Die Zinkacetatmenge in der Lösung kann z. B. von 3 bis 20 g variiert werden. The whole process is then repeated three more times. The layer obtained contains about 0.1 mg ZnO per square centimeter of surface. The transmission for radiation of 2300 A and higher is about 90%; that for radiation below 1900A is about 10%. Ozone can now not be detected even if the heater is used for a long time. The amount of zinc acetate in the solution can e.g. B. can be varied from 3 to 20 g.
Ein identisches Ergebnis erhält man, wenn die Umhüllung des Ultraviolettstrahlers mit einer siliziumtetrachlorid- und zinkcHoridhaltigen Lösung bespritzt wird.An identical result is obtained if the enclosure of the ultraviolet radiator with a silicon tetrachloride and a solution containing zinc chloride will.
