摘要:
Composition including a first component, including furfuryl alcohol and humins and a second component including an acidic polymerization initiator. The composition can be oligomerized to a resin, which has a viscosity in the range of 0.1 to 10,000 Pa·s at 25° C., determined according to ISO3219. The resin, or a blend of furfuryl alcohol and humins as a component A and an acidic polymerization initiator as a component B, separated from each other, may form a kit for an adhesive or impregnation agent.

A composite wood product in accordance with a particular embodiment of the present technology includes a composite substrate and a sealant disposed within a surface portion of the substrate. The substrate includes wood and a binder. The sealant includes photoresponsive molecules present within the surface portion of the substrate at an average concentration greater than 1000 parts per million. In response to a 120-day exposure at 7 inches separation distance to a UV lamp with a UVA (315-400 nm) output of 13.6 W and a UVB (280-315 nm) output of 3.0 W, a CIELab b* value of the substrate decreases by a first amount, a CIELab b* value of the sealant increases by a second amount, and a CIELab b* value of the overall wood product decreases by an amount less than the first amount, increases by an amount less than the second amount, or is unchanged.

摘要:
A commercial scale system and process for chemically modifying wood and then heating the chemically-modified wood. The system/process separates the chemical modification step from the heating step by utilizing two different vessels for the modification and heating steps. The system and process can, in certain situations, include a containment room for preventing escape of vapors from a chemical wood modification reactor, a wood heater, and/or a chemically-modified bundle of wood as the bundle is transported from the wood modification reactor to the wood heater.
摘要:
In one embodiment, the invention relates to a method for rendering a non-metallic substrate stably antimicrobial. The method comprises: (a) contacting the substrate with an antimicrobial surfactant; (b) contacting the substrate with a polymeric binder; and (c) subjecting the substrate, surfactant, and binder to conditions at which the substrate becomes stably antimicrobial. In another embodiment, the invention relates to a substrate into which an antimicrobial surfactant and a binder have penetrated.

Also provided is a method for the application of the additive-containing composition to wood, as well as wood products which have been treated with the composition.
摘要:
This invention relates to a composition for a timber preservative comprising as constituents: i. a Cu-salt; ii. a further biocide; iii. an additive; wherein the additive comprises a polyalkylene ether and; a) an amine or a salt thereof wherein the amine comprises a polyalkylene ether moiety; or b) a fatty acid or a salt thereof; or c) both (a) and (b), wherein a weight ratio of the Cu of the Cu-salt to the additive is in the range from 0.1 to 5.
摘要:
A method of preserving cellulosic material is provided. The method includes contacting the cellulosic material with a paraben-containing monomer and polymerizing the paraben-containing monomer to provide a polymer impregnated within the cellulosic material; or alternatively, first polymerizing the paraben-containing monomer to give a polymer comprising repeat units formed of the monomer and contacting the cellulosic material with the polymer under pressure to provide the polymer impregnated with the cellulosic material. Articles including the cellulosic material and at least one polymer which includes paraben moieties are also provided, such as a wooden plank, a utility pole, a railroad tie, a ship's hull, a wooden utensil, a toy, a model, a piece of furniture, a vehicle, or a serving dish.
摘要:
The present invention relates to the use of modified nanoparticles in wood based panels, in particular OSB-panels for reduction of the emission of volatile organic compounds (VOCs). The invention further relates to a wood based panel containing the modified particles and to a method for producing such a wood based panel.
摘要:
The proposed invention relates to a method for fluid treatment of wood comprising the steps of placing the wood in an airtight tank, evacuating the airtight tank to establish a vacuum environment for the wood, applying a fluid to the wood. Additionally, the method may further comprise the subsequent step of pressurizing the airtight tank to establish a pressurized environment for the wood. The method may further comprise the subsequent step of subjecting the wood to a subsequent heating, and/or the prior step of subjecting the wood to a prior heating by electromagnetic radiation through one or more electrodes.
摘要:
A bamboo shoot squeezing apparatus is provided underground and includes a case, a pressure generation element, and a fixing beam. The case includes a bottom wall, a sidewall, a support piece, and a pressing board. The sidewall and the bottom wall are connected to form a column-shaped cavity, the support piece is fixed on the sidewall and is located above the bottom wall, the pressing board is inside the column-shaped cavity and is located above the support piece, the pressing board, the support piece, and the sidewall together form a squeezing cavity, the fixing beam is located above the pressing board and is fixed on the ground, and the pressure generation element is clamped between the pressing board and the fixing beam. The bamboo shoot squeezing apparatus has an advantage of extending a storage period of bamboo shoots and an advantage of a long service life.
