Description

Verfahren zur Herstellung von Lumineszenzschirmen Die Erfindung betrifft ein Verfahren zur Herstellung von Lumineszenzschirm@en, insbesondere für Entladungsröhren. Es ist bereits bekannt, hierbei lein Bindemittel zu verwenden, das den Lumineszenzstoff auf der Leuchtschirmunterlage festhalten :soll, und es ist auch bereits bekannt, das Verfahren so. zu leiten, daß die Körner ,des Lumineszenzstoffes nicht ganz von dem Bindemittel eingeschlossen werden. Bei diesem bekannten Verfahren wird das Bindemittel in flüssigem Zustand auf den Leuchtschirmträger aufgebracht und dann der Leuchtstoff aufgestäubt.Method of making luminescent screens The invention relates to a process for the production of luminescent screens, in particular for discharge tubes. It is already known to use a binder that contains the luminescent substance note on the luminescent screen pad: should, and it is already known, the procedure like that. to conduct that the grains of the luminescent substance are not entirely of be included in the binder. In this known method, the binder applied in the liquid state to the screen carrier and then the phosphor dusted up.

Im Gegensatz dazu wird gemäß der Erfindung das Bindemittel in fein gemahlenem Zustand mit oder ohne Zuhilfenahme einher vorhergehenden Befeuchtung aufgestäubt und vor Einbnngen des Luminophors aufgeschmolzen. Sehr geeignet ist Borsäure, ,die auch ohne vorherige Befeuchtung des Kolbens in genügender Menge haftet: Andere Materialien:, wie z. B. fein gemahlene, leicht schmelzende Gläser, haften schwerer. Bei ihnen ist eine Befeuchtung der Kolbenwandung erforderlich.In contrast, according to the invention, the binder becomes fine ground state with or without the aid of previous moistening dusted on and melted before the luminophore is entangled. Is very suitable Boric acid, which adheres in sufficient quantity even without prior moistening of the piston: Other materials: such as B. finely ground, easily melting glasses, adhere heavier. They require the wall of the piston to be moistened.

PATENTANSPRUCH: Verfahren: zur Herstellung von Lurnineszenzs:chirmen unter Benutzung eines ,die Körner des Lumineszenzstoffes nichtvöllig einschließenden Bindemittelüberzuges aus einer leichter als das Glas des Kolbens schmelzenden Substanz, dadurch gekennzeichnet, daß das Bindemittel in fein. gemahlenem Zustand mit oder ohne Zuhilfenahme einer vorhergehenden Befeuchtung aufgestäubt und vor Einbringen des Luminophors angeschmolzen wird. Claim: Process: for the production of lurninescence: screening using a binding agent coating which does not completely enclose the grains of the luminescent substance and is made of a substance which melts more easily than the glass of the flask, characterized in that the binding agent is fine. ground state with or without the aid of a previous moistening and is melted before introducing the luminophore.
