Description
Vynález sa týká nízkoboritého skla pre nekonečné skleněné vlákna určené predot všetkým do polyesterových živíc ako-výstuže pre lamináty, připadne inej aplikácie v technológiach sklom vystužených plastov.BACKGROUND OF THE INVENTION The invention relates to low-borne glass for continuous filaments intended primarily for all polyester resins as reinforcement for laminates, or other applications in glass-reinforced plastic technologies.
Vo výrobě nekonečných skleněných vlákien má v súčasnosti dominujúce postavenie E-sklo. Je to bezalkalické hlinito-boríto-vápenato-kremičité sklo· o hmotnostnom obsahe oxidu hlinitého 15,5 + 0,5 %, oxidu boritéhoi 8,5 + 0,5 %, oxidu vápenatého 17,5 + + 0,5 °/o a oxidu křemičitého 53,5 + 0,5 %, s nasledovnými íyzikálnymi parametrami.Currently, E-glass has a dominant position in the production of continuous glass fibers. It is an alkali-free aluminum-boron-lime-silica glass with an alumina content of 15.5 ± 0.5%, boron oxide 8.5 ± 0.5%, calcium oxide 17.5 ± 0.5 ° / o and silica 53.5 ± 0.5%, with the following physical parameters.

II.II.
Nevýhoda uvedeného skla je predovšetkým v dvoch faktoroch. Prvým z nich je vzrastajúci nedostatok a v důsledku toho stále stúpajúca cena boritých surovin, druhým je znečisťovanie ovzdušia emisiou boritých zlúčenín a fluoridov, ktoré sú používané v čeriacej zmesi pri taviacom procese. •Z dňvodov zníženia nákladov na výrobu nekonečných skleněných vlákien a odstránenia ekologických problémov je snaha výskumnej a výrobnej činnosti podstatné obmedziť, resp. vylúčiť nežiadúce faktory — obsah oxidu boritého B2O3 a fluoridov.The disadvantage of said glass is mainly in two factors. The first is the increasing scarcity and consequently the increasing price of boron raw materials, the second is the air pollution by the boron compounds and fluorides that are used in the milling mixture in the melting process. • From the point of view of reducing the cost of production of continuous filaments and eliminating environmental problems, the effort of research and production activities is essential to reduce or reduce the costs of production. eliminate unwanted factors - the content of B2O3 boron oxide and fluorides.
Vyššie uvedené nedostatky odstraňuje nízkoborité sklo podlá vynálezu, ktorého· podstata spočívá v tom, že obsahuje 4 až 6 % hmotnosti oxidu boritého B2O3, 52 až 56 % hmotnosti oxidu křemičitého SÍO2, UJ,6 ažThe above-mentioned drawbacks are overcome by the low-borne glass according to the invention, which comprises 4 to 6% by weight of boron oxide B2O3, 52 to 56% by weight of silica SiO2, UJ, 6 to 6
13,5 % hmotnosti oxidu vápenatého CaO, 6,1 až 8,9 % hmotnosti oxidu horečnatého1 MgO,13.5% by weight of calcium oxide CaO, 6.1 to 8.9% by weight of magnesium oxide 1 MgO,
15,1 až 16,8 % hmotnosti oxidu hlinitého AI2O3, 2,5 až 3ť5 % hmotnosti oxidu bárnatého BaO, 0,7 až 1,5 % hmotnosti oxidu zinočnatého ZnO alebo oxidu titaničitého T1O2.15.1 to 16.8% by weight of Al 2 O 3, 2.5 to 3.5% by weight of barium oxide BaO, 0.7 to 1.5% by weight of zinc oxide ZnO or titanium dioxide T1O2.
Výhoda vynálezu spočívá v tom, že je podstatné znížený obsah oxidu boritého B2O3 v skle a nie je potřebné použiť čeriaci zmes s obsahom fluoridov, pričom sa zachovávajú požadované parametre skla.An advantage of the invention is that the content of B2O3 boron oxide in the glass is substantially reduced and that it is not necessary to use a fluoride-containing blackening composition while maintaining the desired glass parameters.
Vynález je v ďalšom objasněný príkladmi prevedenia a doložený obrázkom, ktorý znázorňuje závislost viskozity nízkoboritého skla od teploty v porovnaní so závislosťou viskozity E-skla od teploty.The invention is further elucidated by means of examples and illustrated by the figure which shows the dependence of the viscosity of the low boron glass on the temperature as compared to the dependence of the viscosity of the E-glass on the temperature.

Sklo bolo utavené v pánvovej peci vykurqvacej zemným plynom pri teplote 1 550 °C a zo skla boli ručně vytvarované guličky, ktoré sa použili na ťahanie vlákna z PtRh 30 kelímka s výtokovou tryskou o priemere 1,6 mm a výške 5 mm. Vlákno bolo tahané pri teplotách 1140 až 1 200 °C.The glass was melted in a ladle furnace heated with natural gas at a temperature of 1550 ° C and beads were manually formed from the glass, which were used to pull a filament of PtRh 30 crucible with a 1.6 mm diameter nozzle and a height of 5 mm. The fiber was drawn at temperatures of 1140 to 1200 ° C.
