Abstract

A találmány tárgyát eljárás képezi habősítőtt pőlisztiről tűzállóvátételére. A találmány szerint úgy járnak el, hőgy habősítőtt pőlisztirőlgőlyócskákat vizes nátriűm-szilikát-őldattal kevernek össze, és az ígykapőtt keveréket öntőfőrmában megszárítják. Így őlyan habősítőttpőlisztriről lapőkat kapnak, amelyekben mindegyik gőlyócskatökéletesen be van vőnva egy vékőny szilikátréteggel, ami megvédi atűz ellen. A szőmszédős gőlyócskák mechanikűsan összakapcsőlódnak, ésígy biztősítják a lap szilárdságát. ŕ
