Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung brandgeschützter dichter Formteile aus Holzfasern, die bei einer Temperatur oberhalb der Raumtemperatur mit Wasserglas als Binde-Flammschutzmittel vermischt werden, wobei ein aus diesem Gemisch gebildetes Faservlies auf eine Dichte von <350 kg/m3 verdichtet wird und danach die Erhärtung des Binde-Flammschutzmittels bei Temperaturen oberhalb von 80°C im Verdichtungszustand bei geschlossener Presse erfolgt.
(EN)
The invention relates to a method for the production of fire-resistant dense moulded pieces made from wood fibres, mixed with water glass as a binding flame-protection agent at a temperature above ambient temperature. A non-woven fibre formed from the above mixture is compressed to a density of <350 kg/m3 and then the hardening of the binding flame protection agent carried out in a closed press in the compressed state at temperatures above 80°C.
(FR)
L'invention concerne un procédé de fabrication de pièces usinées denses en fibres de bois ignifugées, lesdites fibres de bois étant mélangées avec du verre soluble en tant que liant ignifuge à une température supérieure à la température ambiante. Selon ce procédé, un nontissé issu de ce mélange est comprimé de façon à présenter une densité inférieure à 350 kg/m3 puis le liant ignifuge est durci à l'état de compression sous presse fermée à une température supérieure à 80 °C.
