Description

Wynalazek niniejszy dotyczy sposobu wytwarzania ekranów fluoryzujacych. Wia¬ domo, ze ekrany takie wytwarza sie w ten sposób, iz material fluoryzujacy, zmiesza¬ ny z kleiwem, przeprowadza sie w zawie¬ sine i w zawiesinie tej pozwala sie mu o- siasc. Mozna równiez umiescic na nosniku z poczatku cienka warstwe kleiwa, po czym — przez rozpylanie — material fluo¬ ryzujacy.Wedlug wynalazku zawiesine znanego materialu fluoryzujacego w znanym klei- wie, umieszczona w znany sposób na no¬ sniku, wypala sie. Wypalanie to mozna u- skuteczniac przez ogrzewanie w powietrzu lub co najmniej w atmosferze zawierajacej tlen.W sposobie wedlug wynalazku oprócz korzysci, polegajacej na usunieciu szkodli¬ wego wplywu kleiwa, osiaga sie te korzysc, iz unika sie oslabienia fluorescencji, wy¬ wolywanego mieleniem materialu fluory¬ zujacego.Wynalazek jest objasniony blizej przy pomocy kilku przykladów.Znany material fluoryzujacy, np. wol- framian wapniowy, miele sie w mlynie ku¬ lowym z octanem amylowym. Dodaje sie roztworu nitrocelulozy w octanie amylo¬ wym; utworzona w ten sposób mase roz¬ prowadza sie na nosniku, suszy na powie¬ trzu i ogrzewa np. do 300°C i wyzej w at¬ mosferze zawierajacej tlen, przy czym ni¬ troceluloza zostaje calkowicie spalona iryzujaca b bardzo dobrych wlasciwosciach.Mozna równiez stosowac, jako, gialerijal fluoryzujacy, krzemian cycjfo^ry, który miele sie w mlynie kulonym z dodaniera alkoholu. Nastepnie dodaje sie rozityog^ kolodium, to jest wysoko nitrowana j^igtpr ze, rozpuszczona w mieszaninie alkoh?^ i eteru. Umieszczanie masy uskutecznia sie w sposób opisany w przykladzie L W te^ sposób latwo udaje sie wytworzyc cienka, przeswiecajaca, l|uj graezraoezysta warstwa która nadaje sie bardzo do lamp Brauna.Wskutek uzycia w tyje crzyl^a^zie yfyap- ko nitrowanej celulozy -4ie. n^a petrzefey 9- grzewania ekranu wytworzonego w celu wypafenia kfeiwa db tak wysokiej tempe¬ ratury. W ce^ otrzymania dobrych wla¬ sciwosci fluoryzujacych pozadane jest jed¬ nak ogrzanie np. do 30Q?C, W podobny sposób mozna równiez u- mieszczac na nosniku wolframian wapnio¬ wy, wplframian kad!mowy, siarczek cynko¬ wy, mieszanine siarczku cynkowego i siarczku kadmowego. PLThe present invention relates to a method of producing fluorescent screens. It is known that such screens are manufactured in such a way that a fluorescent material mixed with an adhesive is suspended and allowed to sit in the suspension. It is also possible to place a thin layer of adhesive on the carrier initially and then - by spraying - the fluorescent material. According to the invention, a suspension of the known fluorescent material in known glue, placed in a known manner on the carrier, burns out. This firing may be effected by heating in air, or at least in an oxygen-containing atmosphere. In the method of the invention, in addition to the advantage of removing the harmful effects of the adhesive, the advantage is also of avoiding the fading of fluorescence due to the grinding of the material. The invention is explained in more detail with a few examples. A known fluorescent material, for example calcium tungsten, is ground in a bucket mill with amyl acetate. A solution of nitrocellulose in amyl acetate is added; the mass formed in this way is distributed on the carrier, dried in the air and heated, for example, to 300 ° C and above in an oxygen-containing atmosphere, whereby the nitrocellulose is completely burned, iridescent and with very good properties. use, as a fluorescent gialerial, cyclic silicate, which is ground in a roller mill with the addition of alcohol. The rosin collodion, i.e., highly nitrated and tetre, dissolved in a mixture of alcohol and ether is then added. The placing of the mass is effected in the manner described in the example LW, and it is easy to produce a thin, translucent, grayscale coating which is very suitable for Braun lamps. . n ^ a petrzefey 9- the heating of a screen made to embellish such a high temperature. In order to obtain good fluorescent properties, however, it is desirable to heat, for example, to 30 ° C. In a similar way, it is also possible to place on the carrier calcium tungstate, cadmium interplanate, zinc sulphide, a mixture of zinc sulphide. and cadmium sulfide. PL
