PROCESS FOR THE ACETYLATION OF WOOD ELEMENTS

摘要

: A composite wood product containing acetylated wood elements characterised by an average value in thickness swelling not exceeding 5 % after subjection to 25 wet-dry/freeze-thaw cycles as described in Table II. Alternative characterisations include moduli of elasticity and rupture, and bending strength. A two stage process for the acetylation of wood elements is also described.
