Pierwszenstwo: Zgloszenie ogloszono: 20.04.1973 Opis patentowy opublikowano: 15.02.197S 73222 KI. 32b,3/06 MKP C03c 3/06 Twórcy wynalazku: Danuta Grabowska, Alicja Olecka, Jacek Swiecki, Wladyslaw Tokarczyk, Helena Zbrowska Uprawniony z patentu tymczasowego: Kombinat Techniki Swietlnej „Po¬ lam" Warszawskie Huty Szkla, Ozarów Mazowiecki (Polska) Masa na wyroby ze sproszkowanego szkla kwarcowego Przedmiotem wynalazku jest masa na wyroby ze sproszkowanego szkla kwarcowego, formowana przez prasowanie i spiekanie szczególnie przydatna do wykonywania pokrywek do tygli i innych wy¬ robów stosowanych w procesach chemicznych.Stosowane dotychczas masy skladaja sie ze spro¬ szkowanego szkla kwarcowego o granulacji poni¬ zej 80 (urn i lepiszcza organicznego. Wyroby wypra¬ sowane z tej masy wykazuja mala wytrzymalosc mechaniczna po wyprasowaniu co jest przyczyna duzej ilosci braków, a takze porowatosc ich po spieczeniu wynosi 25 do 40°/o, a wytrzymalosc me¬ chaniczna na zginanie nie przekracza 100 kG/cm2.Celem wynalazku jest zwiekszenie wytrzymalos¬ ci mechanicznej masy oraz zmniejszenie porowa¬ tosci.Cel ten zostal osiagniety w wyniku zmieszania sproszkowanego szkla kwarcowego oraz gestwy ze szkla kwarcowego w ilosci 100 czesci wagowych sproszkowanego szkla, oraz 65 do 250 czesci wago¬ wych gestwy. Gestwe ze szkla kwarcowego otrzy¬ muje sie w wyniku mokrego mielenia szkla kwar¬ cowego z woda. Granulacja proszku kwarcowego w gestwie nie powinna przekraczac 80 |u,m. Sprosz¬ kowane szklo kwarcowe o granulacji ponizej 2 mm uzyskuje sie w wyniku suchego mielenia. Wytwa- 5 rzanie wyrobów z masy wedlug wynalazku, to jest formowanie ich przez prasowanie oraz spiekanie, przeprowadza sie znanymi sposobami.Masa wedlug wynalazku pozwala na zmniejsze¬ nie ilosci braków w procesie formowania oraz po- io zwala uzyskac wyroby o porowatosci 15 do 20% i wytrzymalosci mechanicznej na zginanie 150 do 200 kG/cm2 PL PLPriority: Application announced: April 20, 1973 Patent description was published: February 15, 197S 73222 KI. 32b, 3/06 MKP C03c 3/06 Creators of the invention: Danuta Grabowska, Alicja Olecka, Jacek Swiecki, Wladyslaw Tokarczyk, Helena Zbrowska Entitled under a temporary patent: Kombinat Techniki Swietlnej "Polam" Warszawskie Huty Szkla, Ozarów Mazowiecki (Poland) Masa for products made of powdered quartz glass. The subject of the invention is a mass for products of powdered quartz glass, formed by pressing and sintering, especially useful for making covers for crucibles and other products used in chemical processes. with a granulation below 80 µm and organic binder. Products pressed from this mass show a low mechanical strength after pressing, which is the cause of a large number of shortages, as well as their porosity after sintering is 25 to 40%, and their strength is The bending strength does not exceed 100 kg / cm2. The aim of the invention is to increase the mechanical strength of the mass and to reduce the pores The aim was achieved by mixing powdered quartz glass and quartz glass dough in an amount of 100 parts by weight of powdered glass, and 65 to 250 parts by weight of dough. Quartz glass is produced by wet grinding quartz glass with water. The granulation of the quartz powder in the gesture should not exceed 80 µm. Powdered quartz glass with a grain size of less than 2 mm is obtained by dry grinding. The production of products from the mass according to the invention, i.e. shaping them by pressing and sintering, is carried out by known methods. The mass according to the invention allows to reduce the amount of shortages in the molding process and allows to obtain products with a porosity of 15 to 20%. and mechanical bending strength 150 to 200 kG / cm2 PL PL
