Description
Verfahren zur Herstellung lumineszierender Schirme, insbesondere bei elektrischen Entladungslampen Die Erfindung bezieht sich auf die Herstellung elektrischer Entladungslampen, deren Innenwände mit lumineszierenden Schirmen versehen sind, unter Benutzung eines Bindefilms, der durch hydrolysierende oder alkoholisierende Stoffe erzeugt wird.Process for the production of luminescent screens, in particular at Electric Discharge Lamps The invention relates to the manufacture of electric discharge lamps Discharge lamps, the inner walls of which are provided with luminescent screens, using a binding film produced by hydrolyzing or alcoholizing Substances is generated.
Es ist bisher bekannt, die Innenwände elektrischer Entladungslampen durch Eingießen von flüssigen Bindemitteln zu benetzen. Dieses Bindemittel wird dann wieder entfernt und die zurückbleibende Menge zu einer klebrigen, dünnen Schicht ausgetrocknet. Auf diese wird dann der lumineszierende Stoff der elektrischen Entladungslampen aufgebracht.It is previously known the inner walls of electric discharge lamps to be wetted by pouring liquid binders. This binder will then removed again and the remaining amount into a sticky, thin layer dried out. The luminescent substance of the electric discharge lamp is then applied to this upset.
Im Patent 905 453 ist ein Verfahren aufgeführt, das einen gleichmäßigeren Bindefilm durch hydrolysierende chemische Stoffe ermöglicht, dergestalt, daß zunächst ein Luftstrom, der mit dem Gas oder Dampf der Substanz angereichert ist, durch die geraden oder gebogenen Rohre geleitet wird. Ein vorher, zur gleichen Zeit oder nachträglich durch die Rohre hindurchgeblasener feuchter Luftstrom bringt eine dünne, gleichmäßige, klebrige Schicht auf die Innenwand der geraden oder gebogenen Rohre auf. Auf diese kann nach einem entsprechenden Trockenvorgang der lumineszierende Stoff od. dgl. unter Bewegung der Rohre aufgebracht werden.In patent 905,453 a method is given that allows a more uniform bonding film by hydrolyzing chemical substances, such that first a flow of air which is enriched with the gas or vapor of the substance is passed through the straight or bent pipes. A stream of moist air blown through the pipes before, at the same time or afterwards applies a thin, even, sticky layer to the inner wall of the straight or curved pipes. After a corresponding drying process, the luminescent substance or the like can be applied to these with movement of the tubes.
Nachfolgend werden weitere chemische Substanzen angegeben, mit denen das im Hauptpatent aufgeführte Verfahren besonders zweckmäßig durchgeführt wird. Bortribromid oder Bortrichlorid werden, da sie eine sehr starke hydrolysierende Neigung haben, für die Aufbringung eines Bindefilms in elektrische Entladungslampen benutzt. Mit diesen Stoffen, gas- oder dampfförmig, kann ein Luftstrom angereichert werden und dieser oder diese Stoffe selbst, gleich in welcher Form, direkt in das gerade oder gebogene Rohr geleitet werden. Durch Einwirkung von Feuchtigkeit, gleich in welcher Art, tritt eine Hydrolysierung ein, die einen gleichmäßig verteilten Bindefilm ergibt. Die als Hydrolyseprodukt auftretenden Bromwasserstoff- bzw. Chlorwasserstoffdämpfe sind zweckmäßig gleichzeitig oder nachträglich auszublasen.Further chemical substances are given below with which the procedure listed in the main patent is carried out particularly expediently. Boron tribromide or boron trichloride, as they have a very strong hydrolyzing tendency, used for the application of a binding film in electric discharge lamps. With These substances, in gaseous or vaporous form, can be enriched in an air stream and this or these substances themselves, in whatever form, directly into the straight or bent pipe. By the action of moisture, regardless of the type Art, a hydrolysis occurs, which results in an evenly distributed binding film. The hydrogen bromide or hydrogen chloride vapors occurring as hydrolysis product are expediently blown out at the same time or afterwards.
In Abwandlung können statt der feuchten Luft Alkoholdämpfe Anwendung finden. -Hierbei tritt eine Alkoholyse auf.Alternatively, alcohol vapors can be used instead of moist air Find. -Alcoholysis occurs here.
In Abwandlung können auch Selendichlorid, Sficiumtetrachlorid und Siliciumchloroform sowie Phosphortribromid und Phosphortrijodid Anwendung finden.Alternatively, selenium dichloride, silicon tetrachloride and Find silicon chloroform and phosphorus tribromide and phosphorus triiodide application.
Besonders geeignet sind Mischungen von Bortribromid oder Bortrichlorid mit Phosphortrichlorid oder Phosphortribromid oder Phosphortrijodid in einem Verhältnis, daß sich als Bindefilm eine neutrale Borylphosphatschicht bildet, die eine sehr feste Bindung des Luminophor an der Glaswand hervorruft und eine außerordentlich hohe Hitzebeständigkeit besitzt.Mixtures of boron tribromide or boron trichloride are particularly suitable with phosphorus trichloride or phosphorus tribromide or phosphorus triiodide in a ratio, that a neutral boryl phosphate layer forms as a binding film, which is a very causes firm binding of the luminophore to the glass wall and an extraordinary has high heat resistance.
