Description
Wynalazek niniejszy dotyczy sposobu wyrobu porowatych cegielek i ksztaltówek ogniotrwalych o malym ciezarze gatunko¬ wym, duzej wlasciwosci izolacyjnej, duzej odpornosci na dzialanie wysokich tempera¬ tur i o duzej wytrzymalosci mechanicznej.Wynalazek polega glównie na tern, ze dokladnie rozdrobiona glina ogniotrwala, szamota, kaolin, kwarc, kwarcyt, krzemien, magnezyt, dolomit, zelazo chromowe, alun- dum i podobne materjaly ogniotrwale mie¬ sza sie z woda na mase plastyczna z dodat¬ kiem proszku glinu, wapnia, cynku, karbi¬ du i podobnych materjalów wytwarzaja¬ cych z woda gazy, poczem mieszanine po dokonanej fermentacji ksztaltuje sie w blo¬ ki, które po wyschnieciu wypala sie w wy¬ sokich temperaturach tak, ze masa zeskwa- rza sie. Przez wytwarzanie gazów wytwa¬ rza sie w masie duza ilosc pór, które prze¬ waznie pozostaja, jezeli formowanie bylo dokonane z nalezyta ostroznoscia. Dzieki wypalaniu bloki otrzymuja niezbedna me¬ chaniczna wytrzymalosc i strukture, która najwiecej jest podobna do struktury pu¬ meksu. Otrzymany produkt przewyzsza znacznie naturalne skaly porowate ognio- trwaloscia dzieki nieobecnosci wiekszych ilosci latwoplynnych krzemianów. Ciezar gatunkowy przy odpowiedniem wykonaniu moze byc zmniejszony do polowy (albo jeszcze i wiecej) ciezaru gatunkowego, któ¬ ry posiadaja z tego samego materjalu w zwykly sposób wytworzone cegly wypala-ne. Celem przyspieszenia wytwarzania sie w masie gazów, jezeli masa jest sporzadzo- ria z proszku*metalowego, stosuje sie celo¬ wo dodatek alkaljów, wapna lub innych materjalów zasadowych, które przyspie¬ szaja reakcje miedzy metalem i woda.Nie jest konieczne, aby calkowity mate- rjal ogniotrwaly byl w postaci maki, lecz wieksza lub mniejsza czesc jego moze byc gruboziarnista i posiadac wielkosc ziarn do 2 milimetrów. Im wieksza jest zawartosc procentowa materjalu drobnego w rodza¬ ju maki, tem wieksza jest porowatosc, i od¬ wrotnie. Wieksza ilosc w mieszaninie ma¬ terjalu gruboziarnistego jednakowoz powo¬ duje, ze produkt wypalany otrzymuje wiek¬ sza wytrzymalosc mechaniczna.Znany juz byl sposób wytwarzania z ce¬ mentu albo podobnych materjalów bloków porowatych zapomoca dodawania do masy materjalów wytwarzajacych gazy, lecz spo¬ sób ten nie byl dotychczas stosowany do wyrobu ogniotrwalych materjalów, które dopiero dzieki rozgrzewaniu do wysokiej temperatury moga byc spiekane w stale bryly. PLThe present invention relates to a method of producing porous refractory bricks and shapes with a low weight, high insulating properties, high heat resistance and high mechanical strength. quartz, quartzite, flint, magnesite, dolomite, chromium iron, alumina and similar refractory materials are mixed with water to form a plastic mass with the addition of powders of aluminum, calcium, zinc, carbide and similar materials producing water, gases, and then the mixture, after the fermentation has been carried out, forms into blocks which, after drying, burn out at high temperatures, so that the mass peels off. Due to the production of gases, a large number of pores are created in the mass, which usually remain if the shaping was done with due care. Due to firing, the blocks obtain the necessary mechanical strength and a structure that is at most similar to that of the box. The obtained product significantly exceeds the natural scales of porous fire resistance due to the absence of larger amounts of liquid silicates. The specific weight, with appropriate design, can be reduced to half (or even more) that of the specific weight, which is made of the same material in the usual manner of fired bricks. In order to accelerate the formation of gases in the mass, if the mass is made of metal powder, the addition of alkali, lime or other basic materials is purposefully used to accelerate the reaction between the metal and water. - the refractory rjal was in the form of flour, but most or less of it may be coarse-grained and have a grain size of up to 2 millimeters. The greater the percentage of fine material in the flour type, the greater the porosity, and vice versa. The greater amount of coarse-grained material in the mixture, however, causes the fired product to receive greater mechanical strength. There has already been a known method of making porous blocks from cement or similar materials by adding gas-producing materials to the mass, but this method is It has not been used so far for the production of refractory materials, which can be sintered into solid lumps only thanks to heating to high temperature.
