METHOD FOR FORMING A PRODUCT FROM A WOODEN COMPOSITE MATERIAL, A PRODUCT FROM A WOODEN COMPOSITE MATERIAL AND A PLANT FOR PRODUCING A PRODUCT FROM A WOODEN COMPOSITE MATERIAL

摘要

1. The method of forming a product from wood composite material by extrusion using a manufacturing plant that contains an extruder, a mouthpiece and a calibration device, characterized in that the surface of the product from wood composite material is roughened, and this roughness is obtained by adjusting the temperature profile of the installation for manufacturing so that the temperature at the inlet end of the extruder is higher than at the outlet end of the extruder, and the temperature in the mouthpiece is higher than at the outlet end e ekstrudera.2. The method according to claim 1, characterized in that the temperature profile prevailing in the installation for manufacturing is controlled in such a way that the temperature of the material supplied to the mouthpiece is 165-185 ° C, preferably 170-180 ° C. The method according to claim 2, characterized in that the installation for the manufacture of contains an adapter that can be connected to the extruder, and the fact that the material temperature in the adapter is 165-185 ° C, mainly 170-180 ° C. 5. The method according to claim 2, characterized in that the temperature profile prevailing in the installation for manufacturing is controlled by dividing the extruder into at least two or more heating zones in the direction of material flow, so that the temperature at the inlet end of the extruder is 200- 235 ° C, and the temperature at the outlet end of the extruder is 140-150 ° C. 6. The method according to claim 4, characterized in that the extruder is divided into six heating zones in the direction of material flow so that the temperature of the first heating zone E1 is 225-235 ° C, preferably 230 ° C, the temperature of the second heating zone E2 is�
