摘要： A super strong and tough densified wood structure is formed by subjecting a cellulose-based natural wood material to a chemical treatment that partially removes lignin therefrom. The treated wood retains lumina of the natural wood, with cellulose nanofibers of cell walls being aligned. The treated wood is then pressed in a direction crossing the direction in which the lumina extend, such that the lumina collapse and any residual fluid within the wood is removed. As a result, the cell walls become entangled and hydrogen bonds are formed between adjacent cellulose nanofibers, thereby improving the strength and toughness of the wood among other mechanical properties. By further modifying, manipulating, or machining the densified wood, it can be adapted to various applications.

摘要： The present invention describes a method for thermo-treatment of wood, where said method comprises the following steps: a) selecting the wood to be as free from knots as possible b) introducing the wood to a temperature increase up to approximately 173° C.; c) maintaining the wood at an ambient temperature of 173° C. for 3-5 hours; d) decreasing the temperature to approx. 20° C.; e) introducing the wood into an autoclave wherein a mixture of linseed oil and mineral oil is applied to the wood, and allowing the mixture to penetrate the wood f) retrieving and storing the treated wood. Furthermore a timber member made with wood treated according to the method is disclosed.

摘要： 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.
