Cl8. C03C3 / 04 The application was announced: 02/01/78 The patent description was published: February 29, 1980 PARTICULARS Pnlentowen Office- p ¦, a - ¦ .. ¦ Creators of the invention: Waclaw Tuszynski, Leszek Mejer, Kazimierz Manczak, Wanda Arczewska Authorized by the patent: Building Research Institute, Warsaw Poland) Lead glass intended for the manufacture of balloons for high pressure mercury lamps The subject of the invention is a lead glass with an increased forming time, called length technological glass, intended for the production of balloons for high-pressure mercury lamps.
W sklad znanej masy szklanej na balony do lamp rteciowych wysokocisnieniowych wchodzi obecnie w stosunkach wagowych na 10000 czesci masy: 7088 czesci Si02 165 czesci AI203, 1449 czesci B^, 727 czesci PbO,424 czesci Na20, 50 czesci Sb203, 13 czesci MgO, 31 czesci BaO, 19 czesci CaO i 34 czesci KaO.The known glass mass for balloons for high-pressure mercury lamps is currently included in to 10,000 parts by weight: 7088 Si02 parts 165 AI203 parts, 1449 B ^ parts, 727 parts PbO, 424 parts Na20, 50 parts Sb203, 13 parts MgO, 31 parts BaO, 19 parts CaO and 34 parts KaO.
Szklo o podanym skladzie ma temperature topnienia 1495°(\ temperature wyrabiania 1283°C i dlugosc technologiczna 21,97 sek. przy wspólczynniku lozszerzalnosci cieplnej 42,67* 10"7O/K. Stosunkowo mala dlugosc technologiczna omawianej masy szklanej niekorzystnie wplywa na proces formowania szkla przeznaczonego do wytwarzania balonów do lamp rteciowych.Glass with the given composition has a melting point of 1495 ° (\ kneading temperature 1283 ° C and a length of technological 21.97 sec. with a coefficient of thermal expansion of 42.67 * 10 "7O / K. Relatively small the technological length of the glass mass in question adversely affects the glass forming process intended for the manufacture of balloons for mercury lamps.
Celem wynalazku bylo opracowanie takiego skladu szkla, który umozliwia zwiekszenie czasu formowania , danego wyrobu.The object of the invention was to provide a glass composition that allows the formation time to be increased of a given product.
W wyniku przeprowadzonych prób i badan stwierdzono, ze cel wynalazku mozna osiagnac przez zwiekszenie zawartosci Al203 i wprowadzenie do skladu szkla w stosunkach wagowych na 10000 czesci masy: 6400 do 7100 czesci Si02 200 do 1900 czesci Al203, 1030 do 1430 czesci B203, 200 do 700 czesci PbO, 200 do 800 czesci Na20, 0 do 12 czesci MgO, 0 do 40 czesci K2 O, 0 do 18 czesci CaO, 0 do 30 czesci BaO, przy czym w masie szklanej moga wystepowac slady zanieczyszczen, zwlaszcza Fe203 i/lub Ti02, a takze dodatki klarujace i przyspieszajace proces topienia, zwlaszcza Sb203 i/lub F2 oraz barwniki.As a result of the tests and research carried out, it has been found that the object of the invention can be achieved by increasing the content of Al203 and introducing into the composition of the glass in terms of weight per 10,000 parts by mass: 6400 to 7100 Si02 parts 200 to 1900 Al203 parts, 1030 to 1430 B203 parts, 200 to 700 PbO parts, 200 up to 800 parts of Na20, 0 to 12 parts of MgO, 0 to 40 parts of K2 O, 0 to 18 parts of CaO, 0 to 30 parts of BaO, with what may be traces of impurities in the glass mass, especially Fe203 and / or Ti02, as well as additives clarifying and accelerating the melting process, especially Sb203 and / or F2, and dyes.
Przyklad. Mase szklana zestawiono w stosunkach wagowych na 10000 czesci masy z 6802 czesci Si02 V 927 czesci A1203, 1257 czesci B203, 486 czesci PbO, 478 czesci Na20, 50 czesci Sb203. Szklo mialo temperature topienia - okolo 1500°C, temperature wyrabiania okolo 1320°C i dlugosc technologiczna okolo 22,5 sek. przy wspólczynniku rozszerzalnosci cieplnej (42±5)* 10"7- l/K.2 103 409Example. The glass mass was compiled in weight ratios per 10,000 parts by weight with 6802 parts SiO 2 V 927 A1203 parts, 1257 B203 parts, 486 PbO parts, 478 Na20 parts, 50 Sb203 parts. The glass had melting temperature - about 1500 ° C, kneading temperature - about 1320 ° C and technological length of about 22.5 sec. at a coefficient of thermal expansion (42 ± 5) * 10 "7- l / K.2 103 409
