Abstract
A method of manufacturing a wood-based board. The method includes applying at least one first fibre mat including a first mix comprising lignocellulosic particles and a binder on a carrier, applying a second fibre mat including a second mix including cellulosic particles and a binder on said at least one first fibre mat, and pressing said at least one first fibre mat into a base layer and the second fibre mat into a surface layer simultaneously, thereby forming a wood-based board. Also, to such a wood-based board.
Claims8
A wood-based board, comprising
- a lower base layer comprising lignocellulosic particles and a binder, an upper base layer comprising lignocellulosic particles and a binder,
- a surface layer comprising cellulosic particles and a binder,
- wherein the upper base layer is arranged between the lower base layer and the surface layer,
- wherein the particle size of the lignocellulosic particles in the lower base layer correspond to the particle size of the cellulosic particles in the surface layer, and
- wherein the particle size of the lignocellulosic particles in the lower base layer differ from the particle size of the lignocellulosic particles in the upper base layer.
