Influence of Surface Damage on Moisture Behavior and Decay Susceptibility of Film Faced Plywood

Popis výsledku v původním jazyce

The protection phenolic film of water resistant birch plywood was mechanically damaged (scratched and scraped) in order to assess its influence on the rate of moisture content uptake and the natural durability of this wood-based material to white-rot fungus Trametes versicolor. Damaged and undamaged samples were exposed to liquid water and water vapor and their change of moisture content was observed. Trametes versicolor degraded these three groups of samples for 14 weeks and its activity was evaluatedas the mass loss after exposure and change in bending properties -modulus of rupture (MOR) and modulus of elasticity (MOE). The rate of the moisture content change was influenced by the mechanical damage to the surface phenolic film only when plywood wasexposed to liquid water. The critical limit - 20% of moisture content - for fungi activity was reached after 10 or 40 days when plywood was exposed to liquid water or vapor, respectively. The mass loss of plywood caused by Trametes versi
