1. A method of manufacturing a fire proof board from strands of wood, the method comprising the following steps in the given order:
(a) providing strands of wood, and then
measuring whether the provided strands of wood have the desired humidity of between 5% and 25%, preferably between 5% and 20%, even more preferably between 8% and 20%, and thenincreasing the humidity of the strands if the measurement shows that they have a humidity that is lower than the desired one, or pre-drying the strands, if the measurement shows that they have a humidity that is larger than the desired one, (b) immersing the strands of wood in a watery solution of a flame retardant chemical composition, (c) separating the strands of wood from each other, (d) at least in part drying the strands of wood, (e) applying an adhesive to the strands of wood, and (f) forming a board of a predetermined shape from the strands. |
