摘要： The following steps are performed in a method of lacquering the luminophore layer of a color picture tube:the luminophore layer is first prewetted,a first aqueous dispersion of a lacquer is applied to the prewetted luminophore layer,this first dispersion is fully dried and heated to above the film formation temperature of the lacquer, thereby producing a first lacquer film,a second aqueous dispersion is applied directly to the first lacquer film, where the said second aqueous dispersion has exactly the same components as the first dispersion and the concentration of the components in the second dispersion corresponds at least to a large extent to the concentration of these components in the first dispersion, andthis second dispersion is fully dried and heated to above the film formation temperature of the lacquer, thereby producing a second lacquer film. This two-stage lacquering process makes it possible obtain screen brightnesses that are about 10% greater than can be obtained by means of conventional single-stage lacquering methods.

US4473488A Process for reclaiming rare-earth metallic oxide and/or rare-earth metallic oxysulfide phosphors 失效

摘要： To a suspension of rare-earth phosphors and sulfidic or selenidic phosphors there is added about 1 to 2% of the amount of hypohalogenite which would be necessary to convert the entire sulfidic or selenidic chalcogenide phosphor into a soluble sulfate and/or selenate. When acidifying the dispersion to which hypohalgenite has been added, to a pH value of preferably between 1.5 and 2, a sedimentation of elementary sulphur and/or selenium forms and becomes attached to the sulfidic and/or selenidic phosphor solids, thus causing these phosphor solids to form sediment. The supernatant suspension containing the rare-earth phosphor is then decanted, and the rare-earth phosphor is reclaimed from the suspension.The disclosed reclaiming process is particularly suitable for decontaminating phosphor mixtures for use in manufacturing color television cathode-ray tubes.

摘要： After being deposited on the luminescent screen, the dispersion lacquer made by the method disclosed forms a smooth and uniform film whose fluidity can be influenced. This results in an improved reflectance behavior of the deposited aluminum film and, thus, in greater picture brightness.The disclosed method consists in that a boric-acid solution is added to the dispersion lacquer which is then set to the desired viscosity by means of a neutralizer.
