Evaluating the durability of particleboard made from steam pretreated poplar wood particles against of Polyporus versicolor
Microbiological degradation of wood and wood products is one of the most important of disadvantage which reduce its useful life. There are various methods to increase the natural durability of wood and wood products and most of them using chemical reagents. In the past, the thermal modification has...
