Abstract

A chemical liquid can be sprayed onto television screens, viewer screens and the like to prevent reflection. The liquid dries rapidly. The liquid is pref. applied by an atomising spray device operating by compressed air or electrically. It may contain a matting agents. Preferred binding agent is nitrocellulose. The chemical liquid pref. has an acetone-base or a nitro-base. The reduction in brightness resulting from the sprayed coating is pref. less than 5%.

Description

Praktische Ausführung:Practical execution:

98S ige Nitrozellulose wird in Aceton oder Nitroverdünnung unter Umrühren aufgelöst. Anschließend werden ca. 3X Campfer zur besseren Bindung und als Weichmacher beigefügt. Als weitere Zusätze sind ein blauer oder grüner Farbstoff (ca. 2ç), sowie ein Mattierungsmittel (ca. 5") erforderlich.98% nitrocellulose is dissolved in acetone or nitro thinner while stirring dissolved. Then about 3X campers are used for better binding and as a plasticizer attached. As further additives are a blue or green dye (approx. 2ç), as well a matting agent (approx. 5 ") required.

Die Mengenzusammensetzungen können variiert werden und sind davon abhängig, wie fein die Zerstäubung erfolgen soll. Bei ganz feinen Düsen muß der Anteil des Lösungsmittels erhöht werden, bei großen Düsen oder gar beim Aufstreichen reicht ein geringer Lösungsmittelanteil.The amount compositions can be varied and are thereof depends on how fine the atomization should be. With very fine nozzles the must The proportion of solvent can be increased, with large nozzles or even when brushing on a small proportion of solvent is sufficient.

Ein höherer Anteil an Mattierungsmittel verlängert die Trocknungszeit.A higher proportion of matting agent extends the drying time.

Die gemischte Flüssigkeit kann z.B. mit dem Handzerstäuber "Jet Pak" der amerikanischen Firma Spray on Products ohne weitere Zusätze aufgetragen werden.The mixed liquid can be e.g. with the hand atomizer "Jet Pak" from the American company Spray on Products can be applied without further additives.

Momentane Situation: Durch die glatte Oberfläche bei Schwarzweiß- oder Farbfernsehgeräten bzw. bei Monitoren kommt es durch Gegenlicht immer wieder zu störenden Lichtreflexen. Dies kann im Extremfall so weit gehen, daß das Fernsehen bei starkem Lichteinfall tagsüber nicht mehr möglich ist bzw. abends vor dem Bildschirm befindliche Lampen im Bildschirm sichtbar werden.Current situation: Due to the smooth surface in black and white or color televisions or monitors, backlighting keeps coming back to annoying light reflections. In extreme cases, this can go as far as television is no longer possible during the day in strong light or in front of the screen in the evening lamps are visible on the screen.

Aufgabe der Erfindung: Die Aufgabe der Erfindung ist es durch Besprühen der Bildschirmoberfläche mit einer chemischen Flüssigkeit das Entstehen der Spiegelung zu vermeiden.Object of the invention: The object of the invention is by spraying the surface of the screen with a chemical liquid causing the reflection to avoid.

Dies wird z.B. durch ein Mattierungsmittel erreicht, das mit Nitrozellulose als Träger und Aceton als Lösungsmittel in Verbindung mit chemischen Weichmachern auf den betreffenden Bildschirm aufgebracht wird.This is achieved, for example, with a matting agent that contains nitrocellulose as a carrier and acetone as a solvent in conjunction with chemical plasticizers is applied to the screen in question.

Die Helligkeitsminderung liegt unter 5.The brightness reduction is less than 5.
