In: Prasad P.N Cited by: Reasons of the strength loss of the acetylated wood based composites were still under question. This research was considered to study springback in the acetylated particleboard and the medium density fibreboard. Chips and fibres were acetylated by using the acetic anhydride to gain different percentages of the weights (WPG).Cited by:

A comprehensive investigation of the effects of heat treatment and acetylation separately and together (combination treatment) on the fungal durability of jack pine wood against a brown rot fungus. acetylated Radiata Pine, untreated Radiata Pine was provided as well. After conditioning, the samples for the EN test (dimension of 15 x 25 x 50 mm) and the ENV test (5 x 10 x mm) were prepared according the following method: The outer 50 cm length and the outer 20 mm width of both sides of a board were excluded from the sampling. Early or incipient stages of brown rot decay display little outward evidence of attack. However, extensive depolymerization of the cellulose within the wood cell wall occurs at very low weight loss, which causes the wood to rapidly lose strength in comparison with the rate of wood mass losses are between five and ten percent in brown rotted wood, in its .

In a recent study, the RH threshold for the diffusion of potassium ions through the wood cell wall of acetylated wood was shown to increase with an increasing WPG [ ]. The threshold in acetylated pine with WPG = 20% was >90% RH, compared to 60%–65% RH in untreated pine under the same by: 4.   A comprehensive investigation of the effects of heat treatment and acetylation separately and together (combination treatment) on the fungal durability of jack pine wood against a brown rot fungus, Poria placenta (pp), and a white rot fungus, Trametes versicolor (tv) has also been by: 5.
