Abstract
Board, wherein this board substantially consists of a material mass which is pressed and which comprises at least two components, namely a first component consisting of organic material, and a second component functioning as a binding agent for said first component, with the characteristic that said material mass is composed differently in the plane of the board. The invention also relates to methods by which such board can be manufactured, as well as to panels comprising such board material.
Claims13
A board comprising:
- a pressed material mass forming a board having a length, a width, and a depth, said pressed material mass having at least first and second components, the first component including an organic material, and the second component including a binding agent arranged for binding said first component;
- wherein said board is free of structural recesses;
- wherein said material mass forming the board comprises a plurality of first portions and a plurality of second portions aligned along a horizontal plane with respect to a top surface of the board in at least one of a length direction and width direction of the board,
- wherein said plurality of second portions have a differing composition than said plurality of first portions,
- wherein said plurality of first portions comprise the first and second components and the plurality of second portions comprise the first and second components and at least a third component, said third component forming part of the pressed material mass itself and being only located within the plurality of second portions so as to be absent in a remainder of the board outside the plurality of second portions,
- wherein said first component comprises wood fiber material,
- wherein said second component is a polycondensation glue, selected from the group consisting of urea formaldehyde glue, melamine glue, melamine formaldehyde glue, methane diphenyl diisocyanate glue, phenol formaldehyde glue, resorcinol formaldehyde glue and resorcinol phenol formaldehyde glue, and
- wherein said board is substantially made as a wood fiberboard selected from the group consisting of medium density fiberboard (MDF) and high density fiberboard (HDF).
A board comprising a pressed material mass having at least first and second components, the first component including an organic material, and the second component including a binding agent arranged for binding said first component;
- wherein said board is free of structural recesses;
- wherein the board further comprises at least a foamed or expanded component comprising an amino resin foam;
- wherein the board defines a substantially homogenous composition along a horizontal plane with respect to a top surface of the board, said foamed or expanded component being concentrated in at least one layer in a center of the board within the board and said foamed or expanded component being absent in at least one layer above or one layer below the at least one layer in the center of the board, and wherein a remainder of said board outside said center of the board is free from said foamed or expanded component.
A board substantially consisting of a pressed material mass having at least first and second components, the first component including an organic material, and the second component including a binding agent arranged for binding said first component;
- wherein said board is free of structural recesses;
- wherein said material mass defines a differing composition located in a plurality of localized material portions across a thickness of the board in a horizontal plane with respect to a top surface of the board in at least one of a length direction and width direction of the board, the plurality of material portions each including at least a third component, said third component forming part of the pressed material mass itself and being only located within the plurality of material portions so as to be absent in a remainder of the board outside the plurality of material portions,
- wherein said first component is a wood fiber material,
- wherein said second component is a polycondensation glue, selected from the group consisting of urea formaldehyde glue, melamine glue, melamine formaldehyde glue, methane diphenyl diisocyanate glue, phenol formaldehyde glue, resorcinol formaldehyde glue and resorcinol phenol formaldehyde glue, and
- wherein said board is substantially made as a wood fiberboard selected from the group consisting of medium density fiberboard (MDF) and high density fiberboard (HDF).
