摘要:
A process and apparatus for treatment of wood, typically moist wood, using a heated bioester derived from vegetable oil or animal fat. The bioester exhibits a decreased viscosity versus other methods of heated oil treatment thereby providing for deep penetration of the heated bioester into the wood.

A method for treating lumber using a treatment composition having white mineral oil. The lumber is submerged in the treatment composition at atmospheric pressure or at an elevated pressure. The white mineral oil replaces moisture removed from the lumber, and thus lubricates the cell structure of the wood. The method is particularly well suited to the treatment of wood flooring blocks, since the white mineral oil is non-toxic and does not pose health or environmental hazards. A fungicide may be added to the treatment composition to inhibit the formation of mold.
摘要:
Production of treated wood with improved penetrability by projectiles is accomplished in an improved pressure treatment with an improved treating solution. The wood is impregnated in a pressure treatment process with a treating solution containing an impregnant, an aliphatic hydrocarbon or halogenated hydrocarbon liquid carrier, a cosolvent if the solubility of the impregnant in the liquid carrier is inadequate, and an effective amount of lubricating oil. After the treating solution has impregnated the wood, the liquid carrier is evaporated leaving treated wood containing an impregnant with internal lubrication due to the oil and possibly some cosolvent.

This invention describes a treatment for wood and other cellulosic materials for minimizing the net dimensional change in the wood and/or cellulosic material between cycles of shrinking and swelling. Cycles of shrinking and swelling compromise the integrity of cellulosic materials, including wood. The water-in-oil composition disclosed herein can be used as a treatment to reduce the magnitude of the dimensional change, thereby mitigating stress and reduce cracking.
摘要:
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.
