Verfahren zur Herstellung von Bau- und Isoliermaterial aus Korkklein.
Bei der Ausführung des den Gegenstand des Patentes Nr. 13511 bildenden Verfahrens hat es sich gezeigt, dass eine gleichmässige Umhüllung der Korkkörner mit Pechstaub in der Praxis auf gewisse Schwierigkeiten stösst, welche wesentlich durch die in den Wandungen der Knetmaschine sich ansammelnde Hitze und das dadurch verursachte Zusammenbacken dos Pechstaubes veranlasst werden. Es wurde gefunden, dass sich dieser Missstand dadurch beseitigen lässt, dass der Pechstaub dem Tonbrei einverleibt wird.
Dies geschieht am zweck- mässigsten in der Weise, dass das Poch zusammen mit trockenem Ton gemahlen und hiedurch zunächst ein inniges Gemenge von Ton-und Pechmehl hergestellt wird. Selbstredend könnte das Pech aber auch für sich gemahlen und das Pechmehl dem Tonbrei beim Kochen des letzteren zugesetzt werden : doch empfiehlt sich das Vermahlen des Pechs zusammen mit trockenem Ton, weil hiedurch einmal die Aufschlemmung des Tons erleichtert und zweitens auch eine vie ! bessere Vormahlung des Pechs herbeigeführt wird. Das Gemenge wird darauf unter geeignetem Zusatz von Wasser und unter beständigem Rühren aufgekocht, der Brei in siedend heissem Zustande dem Korkklein in der Knetmaschine zugesetzt und die Masse in der üblichen- Weise durchgeknetet.
Das in dem Tonbrei gleichmässig verteilte Pechmehl überzieht bei der Kactarbeit gleichzeitig mit dem Ton die Korklörner, so dass letztere dann je in eine dünne Schicht Tonbrei eingehüllt sind, in-welcher gleichmässig verteilt die feineren Pechstäubchen eingebettet liegen. Diese Schicht haftet um so fester an den Korkkörnern, als die Pechstäubchen in der Siedehitze des Tonbreies bereits eine gewisse Klebrigkeit erlangt haben, welche ihr Anhaften am Kork ungemein fördert.
Die Anwendung siedend heissen Tonbreies und die Erwärmung des Pechstaubes haben gleichzeitig die Wirkung, dass in der Knetmaschine eine hinreichend warme Feuchtigkeit herrscht, um innerhalb der Dauer der Knctarbeit alle im Korkklein etwa vorhandenen gequetschten Korkzollen zur vollkommenen Aufquellung zu bringen, so dass der Form- maschine ein fertig gequollenes Korkmaterial überliefert und ein Nachquellen im Trocken- ofen vermieden wird. Die geknetete Masse wird in bekannter Weise geformt und die geformten Stücke im Trockenofen bei etwa 120-f500 C getrocknet.

Process for the production of building and insulating material from small cork.
When carrying out the process forming the subject of patent no.13511, it has been shown that a uniform coating of the cork grains with pitch dust encounters certain difficulties in practice, which are mainly caused by the heat accumulating in the walls of the kneading machine and that caused by it Caking of the pitch dust can be induced. It was found that this deficiency can be eliminated by incorporating the pitch dust into the clay pulp.
The most expedient way to do this is to grind the poch together with dry clay and thereby initially produce an intimate mixture of clay and pitch flour. Of course, the pitch could also be ground on its own and the pitch flour added to the pulp when cooking the latter: however, it is advisable to grind the pitch together with dry clay, because this makes it easier to slurry the clay and also a lot! better pre-grinding of the pitch is brought about. The mixture is then boiled with a suitable addition of water and with constant stirring, the pulp is added to the cork in the kneading machine in the boiling hot state and the mass is kneaded in the usual way.
The pitch flour, which is evenly distributed in the clay, coats the cork grains with the clay at the same time as the clay, so that the latter are each encased in a thin layer of clay in which the finer pitch dusts are embedded evenly. This layer adheres all the more firmly to the cork grains as the pitch dust has already acquired a certain stickiness in the boiling heat of the clay pulp, which greatly promotes its adhesion to the cork.
The use of boiling hot clay pulp and the heating of the pitch dust at the same time have the effect that there is sufficiently warm moisture in the kneading machine to completely swell all the squeezed cork rolls that may be present in the cork, so that the molding machine a completely swollen cork material is delivered and after-swelling in the drying oven is avoided. The kneaded mass is shaped in a known manner and the shaped pieces are dried in a drying oven at around 120 ° -500 ° C.
