Description

Verfahren zum Aufbringen von Leuchtstoffen auf die Glaswände elektrischer Entladungsgefäße, insbesondere Gasentladungsröhren Die Erfindung betrifft ein neues Verfahren, um Leuchtstoffe, d. h. Stoffe, die fluoreszieren oder phosphoreszieren, auf den Glaswänden von Gasentladungsröhren anzubringen.Process for applying phosphors to the glass walls electrical Discharge vessels, in particular gas discharge tubes The invention relates to a new one Method of making phosphors, d. H. Substances that fluoresce or phosphoresce, to be attached to the glass walls of gas discharge tubes.

Das weiter unten im einzelnen beschriebene Verfahren ermöglicht es, eine Vereinfachung des Aufbringens der Leuchtstoffe und weiter eine erhebliche Beschleunigung der Arbeitsgänge durchzuführen. Darüber hinaus schließt es sämtliche Mängel aus, mitdenen,die bisher in Übung befindlichen Verfahren zum Anbringen von Leuchtstoffen verbunden waren, -gleichgültig ob diese Verfahren im Einstäuben der Leuchtstoffe oder im Aufschlämmen der Leuchtstoffe bestanden. Das Verfahren bedeutet also gegenüber dem bisher üblichen Verfahren einen erheblichen technischen Fortschritt.The method described in detail below makes it possible to a simplification of the application of the phosphors and further a considerable acceleration of the operations to be carried out. In addition, it excludes all defects with the methods for attaching phosphors that have been practiced so far - regardless of whether these processes were involved in dusting the phosphors or consisted in slurrying the phosphors. So the procedure means opposite a considerable technical advance compared to the previously customary process.

Die Erfindung besteht darin, daß in den Entladungsgefäßen, wie z. B. Glasröhren, ein Siliconfilm gebildet wird durch Einbringen von Organosilicohalogenen, zweckmäßig Dimethylsilicodichlorid in flüssiger oder Dampfform in solcher Menge, daß die Glaswand ausreichend benetzt ist, der Überschuß wird durch Ausgießen bzw. Ausblasen entfernt. Die Organosilicohalogene sind gut benetzende Stoffe und bilden einen gleichmäßigen Film auf der Glaswand. Durch den Wasserdampf der Luft werden sie hydrolysiert und zu Ring- oder Kettenverbindungen polymerisiert, -die einen flüssigen hochviskosen Film mit sehr geringem Dampfdruck bilden, der den eingebrachten Leuchtstoff festhält.The invention consists in that in the discharge vessels such. B. glass tubes, a silicone film is formed by introducing organosilicohalogens, expediently dimethylsilicon dichloride in liquid or vapor form in such an amount, that the glass wall is sufficiently wetted, the excess is poured out or Blow out removed. The organosilicohalogens are good wetting substances and form an even film on the glass wall. Be by the water vapor of the air they hydrolyze and become ring or Polymerized chain links, -which form a liquid, highly viscous film with very low vapor pressure, the holds the introduced phosphor.
