Description

Zur Verwendung· in der Bauindustrie sind Bauplatten bekannt, die aus nicht porösem Gips oder aus Zellgips bestehen. Beide Arten von Platten haben eine geringe Festigkeit, und die erstere hat überdies ein unerwünscht hohes Gewicht." Zur Erhöhung der Festigkeit hat man nicht porösen Gips mit Mineralfasern gemischt und aus dieser Mischung die Platten hergestellt. Bei derartigen Platten ist es auch bekannt, auf ihre Oberflächen noch Schichten von Mineralfasern aufzukleben. Auch diesen Platten mangelt es an der gewünschten Leichtigkeit, und zudem ist keine t)efriedigende Oberflächenfestigkeit gegeben, da selbst bei aufgeklebten Mineralfaserschichten der nötige innige Verbund mit der Platte fehlt.For use in the building industry, building boards are known which are made of non-porous plaster of paris or from Cell plaster of paris. Both types of plates are poor in strength, and the former also has an undesirably high weight. "To increase the strength, you have non-porous plaster of paris with mineral fibers mixed and made the plates from this mixture. With such plates it is also known Glue layers of mineral fibers on their surfaces. There is also a lack of these records the desired lightness, and in addition, there is no t) e satisfactory surface strength, since even If the mineral fiber layers are glued on, the necessary close bond with the board is missing.

Die Erfindung bezieht sich auf eine durch Mineralfasern verstärkte Gipsplatte, die aus einer inneren Kernplatte aus einer innigen Mischung von Zellgips und Mineralfasern und äußeren, ein Glasfaservlies enthaltenden Deckschichten aus nicht porös gemachtem Gips besteht, der mit dem Gips eine einheitliche Masse bildet.The invention relates to a gypsum board reinforced by mineral fibers, which consists of an inner Core plate made of an intimate mixture of cellular plaster and mineral fibers and outer, a glass fiber fleece containing cover layers made of non-porous plaster of paris, which is uniform with the plaster of paris Mass forms.

Eine derartig zusammengesetzte Gipsplatte besitzt trotz großer Leichtigkeit eine optimale Festigkeit, insbesondere eine hohe Oberflächenfestigkeit.A plasterboard composed in this way has an optimal strength despite its great lightness, especially high surface strength.

Die Erfindung betrifft weiter ein Verfahren und eine Vorrichtung zur Herstellung der neuen Gipsplatte. The invention also relates to a method and a device for producing the new plasterboard.

Das Verfahren besteht darin, daß fortlaufend eine innige aufgebläht schaumige Mischung aus Gips, Wasser und Mineralfasern hergestellt, diese Mischung zu einer Platte geformt, einer oder beiden Hauptflächen der Platte ein mit Gips getränktes Glasfaservlies zugeführt und das Ganze durch eine Presse geschickt wird, in der das Abbinden, und Verbinden der beiden Gipsmassen erfolgt, wobei der Gips der Kernplatte und der Gips der Deckschichten im gleichen Verhältnis mit Wasser angemacht wird, so daß die Abbindezeiten beider Gipsmassen einander möglichst nahe kommen.The process consists in continuously creating an intimate, puffed-up foamy mixture of plaster of paris, Water and mineral fibers made this mixture Shaped to a plate, one or both main surfaces of the plate a glass fiber fleece soaked with plaster fed and the whole thing is sent through a press, in which the setting and joining of the two gypsum masses takes place, the gypsum of the core board and the gypsum of the cover layers being the same Ratio is made up with water, so that the setting times of both gypsum masses each other as possible to come close.

Zweckmäßig wird dem Anmachwasser für den Gips der Kernplatte ein den Gipsbrei bis zu 100% aufblähender, schaumbildender Stoff beigefügt.Appropriately, the mixing water for the gypsum of the core board is the gypsum paste up to 100% puffing, foam-forming material added.

Gute Ergebnisse lassen sich erzielen, wenn für die Mischung mit dem zur Bildung der Platte dienenden Gips Mineralfasern mit einem Durchmesser von einigen zehn Mikron, z. B. 30 Mikron, und einer Länge von einigen Zentimetern, z. B. 1 bis 3 cm, zugesetzt werden.Good results can be achieved if the mixture is used with the one used to form the plate Gypsum mineral fibers several tens of microns in diameter, e.g. B. 30 microns, and one Length of a few centimeters, e.g. B. 1 to 3 cm, are added.

Der Zusatz an Fasern zu dem Gipsbrei für die Kernplatte beträgt zweckmäßig etwa 5 bis 10 g Fasern je 100 g trocknem Gips.The addition of fibers to the gypsum slurry for the core plate is expediently about 5 to 10 g of fibers 100 g of dry plaster of paris.

Die Vermischung wird begünstigt, wenn man das Anmachwasser vorher zum Schäumen bringt und im Augenblick des Zusammenführens von Fasern und Gipsplatte sowie Verfahren
und Vorrichtung zu deren HerstellungMixing is promoted if the mixing water is made to foam beforehand and at the moment when the fibers and plasterboard and the process are brought together
