Abstract
A method for forming a wood composite product by extrusion with a manufacturing apparatus. The temperature profile prevailing in the manufacturing apparatus is adjusted in such a way that the surface of the wood composite product to be formed becomes rough. A wood composite product and an apparatus for manufacturing a wood composite product.
Claims23
A method for forming a wood composite product by extrusion by a manufacturing apparatus that comprises an extruder, a die, and a calibration device, the method comprising:
- making a surface of the wood composite product rough, wherein making the surface of the wood rough comprises adjusting a temperature profile of the manufacturing apparatus such that a temperature is higher at an initial end of the extruder than at a terminal end of the extruder, and the temperature is higher in the die than at the terminal end of the extruder.
An apparatus for manufacturing a wood composite product, the apparatus comprising:
- an extruder,
- a die, and
- a calibration device,
- wherein the extruder and die comprise at least one heating device, wherein the at least one heating device is arranged to heat a composite material flowing in the manufacturing apparatus such that a temperature at an initial end of the extruder is higher than a temperature at a terminal end of the extruder, and a temperature in the die is higher than a temperature at the terminal end of the extruder, wherein a surface of the wood composite product to be formed becomes rough.
An extruded wood composite product, comprising:
- polymer material and adhesive label laminate waste comprising label material, an adhesive layer, and release material, wherein the label material and/or the release material comprise at least one of a wood fiber based component, an organic component, and an inorganic component,
- wherein a surface of the product is rough, wherein the surface comprises a deviation of bulges and depressions on the surface, wherein the deviation is less than 1 mm from an average surface level.
