Wood product and method therefor
View Patent ↗A method comprising adding a suspension of a wood-property-enhancing substance to a wood product precursor. The suspension may be added to the wood product precursor in a production line prior to making a finished wood product. The suspension may be manufactured at a site where the wood product precursor is produced. A finished wood product may be made from the wood product precursor. An article is also described comprising a finished wood product made by adding a suspension of a wood-property-enhancing substance to a wood product precursor.
1. A method comprising:
improving a property of a wood product precursor by adding a suspension of wax suspended in water to a slurry comprising said wood product precursor in a production line prior to making a finished wood product, wherein said property comprises at least one of the following: water repellence, water resistance, water absorption control, sizing control, dimensional stability, thickness swell control, edge sealing, density control, mechanical strength control, and wood preservation.
2. The method according to claim 1 , wherein said suspension is manufactured at a site where the wood product precursor is produced.
3. The method according to claim 1 , wherein said wax comprises at least one of paraffin, paraffin wax, montan wax, candelilla wax, carnauba wax, beeswax, polyethylene wax, and maleated hydrocarbons.
4. The method according to claim 1 , wherein excess heat of producing said wood product precursor is used as part of manufacturing said suspension.
5. The method according to claim 1 , further comprising storing said suspension of wax suspended in water in a first storage container, storing a liquid in a second storage container, and forming said suspension by dispersing said suspension of wax suspended in water in said liquid in a mixing device.
6. The method according to claim 5 , wherein said suspension is added directly from said mixing device to said wood product precursor.
7. The method according to claim 5 , wherein said suspension is fed from said mixing device to an auxiliary mixing device, and said suspension is added from said auxiliary mixing device to said wood product precursor.
8. The method according to claim 6 , further comprising controlling flow of said suspension to said wood product precursor with a control feeder valve.
9. The method according to claim 7 , further comprising controlling flow of said suspension to said wood product precursor with a control feeder valve.
10. The method according to claim 8 , comprising producing and adding said suspension to said wood product precursor in a production line, wherein said production line and said control feeder valve operate in a closed control loop.
11. The method according to claim 9 , comprising producing and adding said suspension to said wood product precursor in a production line, wherein said production line and said control feeder valve operate in a closed control loop.
12. The method according to claim 1 , further comprising forming a finished wood product from said wood product precursor.
13. An article comprising:
a finished wood product made by adding a suspension of wax suspended in water to a wood product precursor, said suspension improving a property of said wood product precursor, wherein said property comprises at least one of the following: water repellence, water resistance, water absorption control, sizing control, dimensional stability, thickness swell control, edge sealing, density control, mechanical strength control, and wood preservation.
14. The article according to claim 13 , wherein said suspension is added to said wood product precursor in a production line prior making said finished wood product.
15. The article according to claim 13 , wherein said suspension is manufactured at a site where the wood product precursor is produced.
16. The article according to claim 13 , wherein said wax comprises at least one of paraffin, paraffin wax, montan wax, candelilla wax, carnauba wax, beeswax, polyethylene wax, and maleated hydrocarbons.
