Fire proof oriented strand board and its manufacture |
| 摘要 |
The invention pertains to 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 having a humidity between 5% and 25%, preferably between 5% and 20%, even more preferably between 8% and 20%, (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 thereby providing dry impregnated strands of wood, (e) applying an adhesive to the strands of wood, and (f) forming a board of a predetermined shape from the strands. The invention furthermore pertains to a board formed by a plurality of strands of wood that are compressed and bonded together with an adhesive, wherein the board further comprises a flame retardant chemical composition, said composition comprising a phosphate compound. |

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
measuring whether the provided strands of wood have a desired humidity between 5% and 20%, preferably between 8% and 20%,increasing 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 by stirring the mixture of strands and watery solution of the flame retardant chemical composition, (d) at least in part drying the strands of wood to a humidity of between 4% and 10%, preferably between 4% and 8%, thereby providing dry impregnated strands of wood, (e) applying an adhesive to the strands of wood, and (f) forming a board of a predetermined shape from the strands. |
