Abstract

Wood flour is treated by carrying out the following steps: preparation of an aqueous solution of a weak organic acid, treatment of the wood flour with the prepared solution and drying of the impregnated wood flour obtained, the absorbed moisture being completely removed. The wood flour obtained can be used as an interlayer in the packaging of glass plates.
