Method of making medium density fiberboard
Abstract
The present invention provides a method for producing an MDF board from pulp from a fibrous lignocellulose material using a treatment or pretreatment step which exposes the material to oxalic acid or oxalic acid derivatives (particularly dialkyl ester derivatives, particularly in the vapor phase). The treated wood is then subjected to a sugar extraction wash and refined using any one of the several pulping methods to produce a final pulp product. Once this is done the pulp is used to make MDF boards having improved water repellency properties.
