摘要：
A method for managing the water sorption of a board by layered sizing is provided, such that the sizing of a central layer is effected with a hydrophobic and fast-curing adhesive, and the surface sizing in preparation for calendering is effected with an adhesive which is hydrophilic during its curing period, such that, during a surface wetting process, water sorption occurs substantially only into a topliner.
