Abstract

Laboratory investigations have been conducted with the aim of producing wood particle boards with formaldehyd content less than that of initial wood particles. Wood particle boards have been produced on the basis of low-mole urea-formaldehyde resins using mole ratios of urea to formaldehyde 1∶1.2 and 1∶1.15. Physical-mechanical properties of the boards are similar to those made on the basis of commercial-grade resins.

Zusammenfassung

Laborversuche wurden durchgeführt mit dem Ziel, Spanplatten zu produzieren, deren Formaldehydgehalt geringer ist als derjenige der eingesetzten Holzspäne. Die Späne wurden mit Harnstoff-Formaldehyd-Harz verleimt, wobei Molverhältnisse von 1∶1,2 und 1∶1,15 (Harnstoff: Formaldehyd) verwendet wurden. Die physikalischmechanischen Eigenschaften dieser Platten waren mit denen von Kontrollplatten auf der Basis kommerzieller Harzgemische vergleichbar.
