Gaseous boron treatments of wood and wood products
A J Bergervoet, R Burton, K Nasheri, D R Page, P Vinden
Treatment of wood and wood products by gaseous organoborates has now been under study for about 5 years. This technique has potential for boron treatment of a wide range of substrates from solid wood through to wood composite materials such as particleboard or wet and dry formed fibreboards. The vapour treatment technique is proving to be very flexible in that it can be adapted to integrate into a wide range of process operations and can accommodate special loading requirements. This paper updates the present research in this area and describes treatment of different wood species and wood composite products. We will also anticipate where some of these developments may lead.
