Description
Ogniotrwale masy ceramiczne posiada¬ ja duza odpornosc na dzialanie czynników chemicznych, mechanicznych i cieplnych, jednak niektóre z tych mas wykazuja te wade, iz nie daja sie dobrze formowac.Szklo natomiast daje sie doskonale formo¬ wac, lecz wskutek obecnosci w niem sklad¬ ników zasadowych nie ma odpornosci, wla¬ sciwej masom ceramicznym.Zgodnie z wynalazkiem zamiast mas ceramicznych, jako materjalu wyjsciowe¬ go, do wytwarzania przedmiotów dowol¬ nego ksztaltu stosuje sie szklo.Sposób wedlug wynalazku polega na tern, ze ze stopu szklanego, zawierajacego skladniki zasadowe, wytwarza sie w zna¬ ny sposób przedmioty, a po ich skrzepnie¬ ciu usuwa sie ze szkla calkowicie lub cze¬ sciowo skladniki zasadowe, nadajace szklu latwotopliwosc, a takze mala odpornosc chemiczna, mechaniczna i cieplna. To usu¬ wanie skladników zasadowych uskutecz¬ nia sie, dzialajac na mase szklana woda lub wodnemi roztworami zwiazków o od¬ czynie zasadowym, np. sody zracej, sody i t. d., lub zwiazków o odczynie kwasnym, np. dwutlenku wegla, kwasu octowego i t. d. pod zwiekszonem cisnieniem i w pod¬ wyzszonej temperaturze, albo tez stosujac inne srodki, powodujace odalkalizowanie szkla.Przyklad. Probówki, wytworzone wjakikolwiek znany sposóh z. latwotopliwe- go szkla, wstawia sie do autoklawu o po¬ jemnosci. 1 litra i zalewa 600 cm3 wody i ogrzewa w ciagu 8 — 10 godz do tempera¬ tury 280 — 300°, poczem probówki studzi w autoklawie lub poza nim.Lugowanie szkla woda w podwyzszonej temperaturze i pod zwiekszonem cisnie¬ niem jest znane przy badaniu szkla pod wzgledem jego zachowania sie na dziala¬ nie chemiczne. Przedmiotem wynalazku niniejszego jest nie srodek do odalkalizo- wania szkla, lecz samo jego odalkalizowy- wanie w celu wytwarzania produktu, któ¬ ry swemi wlasciwosciami przypomina pro¬ dukty z masy ceramicznej.Ponadto wynalazek przewiduje spieka¬ nie przedmiotów, wytworzonych w opisa¬ ny sposób, zapomoca mniej lub bardziej energicznego wypalania, dzieki czemu o- siaga sie zwiekszenie wytrzymalosci i ge¬ stosci produktów.Zmieniajac sklad masy wyjsciowej al¬ bo stosujac odpowiednie dodatki, mozna w znacznym stopniu wywierac wplyw na wlasciwosci i wyglad wyrobów. PLRefractory ceramic masses have a high resistance to the action of chemical, mechanical and thermal factors, but some of these masses show the disadvantage that they do not form well. Glass, on the other hand, can be formed perfectly, but due to the presence of its components. According to the invention, glass is used instead of ceramic masses as a starting material for the production of objects of any shape. The method according to the invention consists in , objects are produced in a known manner, and after they solidify, basic components are completely or partially removed from the glass, which make the glass fusible, and also have low chemical, mechanical and thermal resistance. This removal of basic components is achieved by treating the mass of glass with water or with aqueous solutions of alkaline compounds, e.g. sodium, baking soda, etc. under increased pressure and at elevated temperatures, or by using other measures that cause the glass to be de-alkalised. The test tubes, made by any known method of fusible glass, are placed in a volumetric autoclave. 1 liter is poured over 600 cm3 of water and heated for 8-10 hours to a temperature of 280-300 °, then the test tubes are cooled in an autoclave or outside of it. Leaching the glass with water at elevated temperature and under increased pressure is known when testing glass in terms of its behavior to chemical action. The subject matter of the present invention is not a glass de-alkalization agent, but the de-alkalization itself in order to produce a product whose properties resemble ceramic mass products. Moreover, the invention envisages sintering objects produced in the manner described. , by using more or less vigorous firing, thus increasing the strength and density of the products. By changing the composition of the starting mass or by using appropriate additives, it is possible to significantly affect the properties and appearance of the products. PL
