Description
Wärmeschutzmittel Es ist bekannt, daß man Wärmeschutzmittel, wie z. B. Schalen, Steine, Platten usw.,= herstellen kann, wenn man pulverförmige Materialien und geeignete Bindemittel mit Hilfe von Saponinlösungen oder anderen schaumerzeugenden Mitteln zu einer porösen schaumigen Masse schlägt und diese in Formen erstarren läßt.Heat protectants It is known that heat protectants, such as. B. bowls, stones, plates, etc., = can be produced if you use powdery materials and suitable binders with the help of saponin solutions or other foam-generating agents Beats agents into a porous foamy mass and solidify them in forms leaves.
Wenn man für diesen Zweck die Rückstände aus der Tonerdeaufschließung, sogenannten Si-Stoff mit hohem Kieselsäuregehalt, zusammen mit gelöschtem Kalk und Einem bekannten Schaummittel, wie z. B. Saponin, verwendet, so erhält man in nicht vorauszusehender Weise nach Abbinden und Trocknen ein Material größtmöglicher Feinporigkeit; welches in seiner Isolierfähigkeit die besten und teuersten Erzeugnisse, nämlich die aus Magnesiumcarbonaten hergestellten Isoliermittel, in ihrer Wirkung :erreicht bzw. übertrifft.If one uses the residues from the alumina digestion for this purpose, so-called Si substance with high silica content, together with slaked lime and A known foaming agent, such as. B. saponin, is not obtained in predictably, after setting and drying, a material with the greatest possible fine pores; which in its insulating ability the best and most expensive products, namely the isolating agents made from magnesium carbonates, in their effect: achieved or exceeds.
Der Vorteil ist besonders in die Augen fallend, wenn man die Wärmeleitzahlen der bisher bekannten Isoliermittel mit denen des neuen Produktes vergleicht. Es sind für Schalen bei Mitteltemperaturen von zoo° folgende Wärmeleitzahlen bekannt: aus Magneeia 0,o5 i, aus Leichtkieselgur 0,057, aus Kieselur (Schale gebrannt) 0,o95._ Das neue Erzeugnis weist beider genannten Temperatur Wärmeleitzahlen von 0,048 bis 0,05 i auf.The advantage is particularly noticeable when one compares the thermal conductivity of the previously known insulating materials with those of the new product. The following thermal conductivity coefficients are known for shells at mean temperatures of zoo °: from Magneeia 0.057 i, from light kieselguhr 0.057, from kieselur (burnt shell) 0.095 on.
Es ist bekannt, Wärmeschutzmittel aus Si-Stoff und Schaumbildnern und Alkalien herzustellen, die bei ioo° getrocknet und schließlich auf 400° erhitzt werden. Demgegenüber erfolgt die Herstellung des Wärmeschutzmittels nach der Erfindung, also mit Kalk als Bindemittel, ohne Zufuhr größerer Wärmemengen. Es kann z. B. die Trocknung an der Luft vorgenommen werden. Ausführungsbeispiel Man verwendet 50 kg Rückstand aus der Tonerdeaufschließung, welche man mit Wasser aufschlämmt, 12 kg gebrannten Kalk (= 16 kg gelöschter Kalk) und ioo bis Zoo g Saponin.It is known to produce heat protection agents from Si material and foaming agents and alkalis, which are dried at 100 ° and finally heated to 400 °. In contrast, the heat protection agent according to the invention is produced, that is to say with lime as the binding agent, without the supply of large amounts of heat. It can e.g. B. the drying can be carried out in the air. 50 kg residue embodiment Use is made of the Tonerdeaufschließung which slurrying with water 12 kg quicklime (= 1 6 kg slaked lime) and ioo to Zoo g saponin.
