Abstract
Samples of black cork agglomerate boards were observed by scanning electron microscopy, prior and after different densifications. These boards were densified under conditions previously defined, and were observed in two directions, parallel and perpendicular to the compression axis. The relationship between the average cell wall distance and the compression applied was studied and it was found that the maximum densification is achieved with a pressure of ca. 3 MPa. Some aspects of the influence of densification treatments on the chemical composition of the material were also broached.
Zusammenfassung
Proben von Korkplatten wurden vor und nach verschiedenen Verdichtungsprozessen im Rasterelektronenmikroskop untersucht. Die Beobachtungen erfolgten in zwei Ebenen, parallel und senkrecht zur Verdichtungsrichtung. Dabei wurde das Verhältnis der durchschnittlichen Zellwandabstände zum Preßdruck ermittelt. Maximale Verdichtung erfolgte bei einem Druck von ca. 3 MPa. Mögliche Auswirkungen der Verdichtungsbedingungen auf die chemische Zusammensetzung werden ebenfalls diskutiert.
