Tafeln zur Herstellung von Brillen, Blenden o. dgl. für Schweißersehutzzweeke.Panels for the production of glasses, panels o. The like. For Protective welder purposes.
Gegenstand der vorliegenden Erfindung sind Tafeln zur Serstellung von Brillen, Blenden o. dgl. für Schweißersehutzzweeke auf der Basis durchsichtiger,TJY-Absorber und ggfl. Weichmacher und/oder Farbstoffe enthaltender Kunststoffe, wie Celluloseacetat, gekennzeichnet durch einen Gehalt an Euß. The present invention relates to panels for production of glasses, screens o. the like. For welder protective purposes on the Base transparent, TJY absorber and, if applicable, Plasticizers and / or Plastics containing dyes, such as cellulose acetate, characterized by a content of black.
Bas Material wird z.B. in folgender Weise hergestellt:Bas material is manufactured e.g. in the following way:
3OOO g Aeetyleellulose (Essigsäuregehalt ca. .52"-55$)*3OOO g acetyl cellulose (acetic acid content approx. 52 "-55 $) *
200 g Dimethylphthalat,200 g dimethyl phthalate,
25Ο g Triphenylphosphat und25Ο g triphenyl phosphate and
550 g Trichloräthylphosphat . -""_■■■550 g of trichloroethyl phosphate. - "" _ ■■■
werden in einem Kneter mit der notwendigen Menge eines Lösungsmittels, wie z.B. Aceton oder einem Alkoholbenzolgemisch, homogenisiert. Darauf werden 16 g eines handelsüblichen FV-Absorbers, z.B. auf der Basis von Acetophenon, 19»8 g Farbruß, z.B. Spezialschwarz,und 0,84 g eines löslichen grünen Farbstoffs, z.B. Filterblaugrün, zugegeben. Die Masse wird in an sieh bekannter Weise gewalzt und zu Fellen ausgezogen. Die Felle werden dann zu einem Block versehweißt und von diesem werden Tafeln bestimmter Stärke abgeschnitten. Die Tafeln werden getrocknet und in einer Plattenpresse unter Druck und Wärme poliert. Die polierten Tafeln ent-are homogenized in a kneader with the necessary amount of a solvent such as acetone or an alcohol benzene mixture. 16 g of a commercially available FV absorber, e.g. based on acetophenone, 19 »8 g carbon black, e.g. special black, and 0.84 g of a soluble green dye, e.g., filter blue green, was added. The mass becomes in a manner known per se rolled and drawn into skins. The skins are then welded into a block and from this sheets of a certain thickness are made cut off. The panels are dried and polished in a platen press under pressure and heat. The polished panels
sprechen den BIN-Vorschriften 4646 und 4^47 über Sehweißersehutzseheiben. Je nach der geschnittenen Wandstärke werden die verschiedenen Schutzstufen erreicht.speak the BIN regulations 4646 and 4 ^ 47 about white glasses. Depending on the cut wall thickness, the different levels of protection are achieved.
Die TJV-Bedingungen werden mit Hilfe des handelsüblichen UV-Absorbers, die Ultrarotbedingungen durch den zugegebenen Büß erfüllt. Der grüne Farbstoff dient lediglieh zur Herstellung eines visuell angenehmen Farbtones.The TJV conditions are determined with the help of the commercially available UV absorber, the ultrared conditions fulfilled by the added penance. The green dye serves only to produce a visually pleasant shade.
