Abstract

Bei einem Verfahren zur kontinuierlichen Herstellung von Span- oder Faserplatten aus lignocellulosehaltigen Rohstoffen werden die Rohstoffe in Span- und/oder Faserform mit einem NCO-Gruppen aufweisenden Bindemittel beleimt, zu einer Matte geformt und unter Einwirkung von Wärme zu der Span- oder Faserplatte verpreßt. Dabei wird ein äußeres Trennmittel insbesondere auf den Preßzulagen vor der Verpressung aufgebracht. Als Trennmittel findet Talkum Verwendung.In a process for the continuous production of chip or Fiberboard made from raw materials containing lignocellulose the raw materials in chip and / or fiber form with an NCO group containing binder glued, formed into a mat and under the influence of heat to the chipboard or fiberboard pressed. An external release agent is used in particular the pressing allowances applied before pressing. As a release agent talc is used.
