Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania geopolimeru, który polega na tym, że do intensywnego mieszalnika przeciwbieżnego wprowadza się szkło wodne w ilości od 5% do 30% mas. i roztwór wodorotlenku sodu (NaOH) o stężeniu 10 — 14 M w ilości od 5% do 10% mas. i homogenizuje się w czasie od 30 s do 180 s przy prędkości mieszadła od 1000 do 1500 obr./min i prędkości obrotowej misy od 30 do 60 obr./min, aż do uzyskania jednorodnej cieczy aktywującej, następnie dodaje się surowiec krzemowo-glinowy, korzystnie popiół lotny najkorzystniej ze spalania węgla, po czym prowadzi się intensywne mieszanie w czasie od 30 s do 180 s przy prędkości mieszadła od 1000 do 2000 obr./min i prędkości obrotowej misy od 30 do 60 obr./min, aż do uzyskania jednorodnej masy reakcyjnej i poddaje procesowi granulacji i mechanicznego zagęszczania w czasie od 120 do 180 s minuty w mieszalniku przeciwbieżnym, przy czym całkowity stosunek masy popiołu do masy cieczy aktywującej wynosi od 1,6 do 2,6, a cały proces prowadzony jest w czasie nie więcej niż 5 minut w temperaturze od 15°C do 25°C.The subject of the application is a method for obtaining a geopolymer, which consists in introducing water glass in an amount of 5% to 30% by weight and sodium hydroxide (NaOH) solution with a concentration of 10 - 14 M in an amount of 5% to 10% by weight into an intensive counter-rotating mixer. and homogenized for a time from 30 s to 180 s at a mixer speed from 1000 to 1500 rpm and a bowl rotational speed from 30 to 60 rpm, until a homogeneous activating liquid is obtained, then a silicon-aluminum raw material is added, preferably fly ash, most preferably from coal combustion, after which intensive mixing is carried out for a time from 30 s to 180 s at a mixer speed from 1000 to 2000 rpm and a bowl rotational speed from 30 to 60 rpm, until a homogeneous reaction mass is obtained and subjected to a granulation and mechanical compaction process for a time from 120 to 180 s minutes in a counter-rotating mixer, wherein the total ratio of the ash mass to the activating liquid mass is from 1.6 to 2.6, and the entire process is carried out for no more than 5 minutes at a temperature from 15°C to 25°C.
