METHOD OF PRODUCING A BUILDING PANEL AND A BUILDING PANEL |
| 摘要 |
A method of producing a building panel (1), including: providing a core (2), applying a balancing layer (6) having a first moisture content on a first surface (3) of the core (2), the balancing layer (6) comprising a sheet impregnated with a thermosetting binder, applying a surface layer (12) having a second moisture content on a second surface (4) of the core (2), the surface layer (12) comprising a thermosetting binder, adjusting the first moisture content of the balancing layer (6) such that the first moisture content of the balancing layer (6) is higher than the second moisture content of the surface layer (12) prior to curing, and curing the surface layer (12) and the balancing layer (6) by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel (1). |

1. A method of producing a building panel, comprising:
providing a core, applying a balancing layer on a first surface of the core, wherein the balancing layer has a first moisture content and comprises a sheet impregnated with a thermosetting binder, applying a surface layer on a second surface of the core, wherein the surface layer has a second moisture content and comprises a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing by applying heat and pressure, and curing the surface layer and the balancing layer by applying heat and pressure. |
