Abstract
The present invention is a process for pressure treating wood and includes wood which has been pressure treated by the process. The process comprises infusion into the wood of a solution in water of an anhydride or the analogous acid of an anhydride, followed by removal of moisture from the wood and the infusion of the wood with a molten waxy solid comprising hydrocarbon paraffins or saturated fatty acids. The molten waxy solid then solidifies, filling all voids in the wood.
Claims7
A process for treating wood comprising the steps of:
- (a) drying the wood to a moisture content below ten percent (10%);
- (b) evacuating the air from the wood;
- (c) infusing a solution of anhydride and water into the wood;
- (d) drying the wood to a moisture content below eight percent (8%);
- (e) evacuating the air from the wood again while the wood istill at a high temperature from the step of drying below eight percent (8%) moisture;
- (f) infusing a molten waxy solid including an acid neutralizer into the wood;
- and
- (g) cooling the wood to room temperature.
