Abstract
The 10 years' industrial and research experience in South Africa in the manufacture, formulation and application of tannin-based adhesives for particleboard, plywood, glulam and fingerjoints is reviewed and discussed. The results obtainable for wood products manufactured with tannin-based adhesives are presented. New techniques for industrial application and some important characteristics of the adhesive correlated to their chemical structure are reviewed.
Zusammenfassung
Die vorliegende Arbeit gibt einen Überblick über Erfahrungen, die während der letzten zehn Jahre hinsichtlich Formulierung, Herstellung und Anwendung von Tannin-Leimen für die Spanplatten-, Sperrholz- und Leimbindererzeugung sowie für die Herstellung von Keilzinkenverbindungen in Südafrika gesammelt wurden. Repräsentative Versuchsergebnisse werden aufgeführt. Neuartige industrielle Anwendungstechniken und bemerkenswerte Eigenschaften von Leimen, die mit ihrer chemischen Struktur zusammenhängen, werden besprochen.
