Proceedings of the Canadian waferboard symposium. Waferboard can be regarded as a successful structural panel in the recent history of wood products. To recognize this, the Waferboard symposium series concept was first initiated in 1980. The second Waferboeard symposium - held from June 1- 3 1982 - based its program on a critical review of the first meeting. The sessions covered the following subjects: Process and manufacture; Product standard and markets; Adhesive technology; Product performance; Resource potential; Equipment up-date.
The susceptibility of non-veneered composite panel products to decay is greater than solid timber when exposed to high moisture contents and severe decay hazard conditions. Preservative chemicals incorporated into these products at various stages of manufacture generally improve the decay resistance of these materials but certain strength properties, especially internal bond, are adversely affected. It appears from the literature survey that treatment of the composite panel products with ACA type preservative system could provide adequate protection with acceptable loss in the strength properties of the panels.
