    摘要： A process for producing a lignocellulose-containing, plastic-coated and printable molding (26), in particular in sheet form, comprising the steps of: a) producing a layer (A, B′) containing lignocellulose-containing particles according to the shape of the molding to be produced (26);
    b) applying a layer (C) of particles containing electron beam-reactive thermoplastic onto the layer produced according to the preceding feature;
    c) heating the layers (A, C) produced according to the preceding features such that thermoplastic particles melt into the layer containing lignocellulose-containing particles (Cs);
    d) pressing the layers heated according to feature (1c); and
    e) irradiating the layers pressed according to feature (1d) with electrons in the energy range from 1 MeV to 10 MeV. The process is for example elucidated with reference to an MDF sheet one-sidedly provided with a polymer layer.

    摘要： A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives, while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapors, tars and chars. Using a cone calorimeter burn test method, dFR treated wood products show a significant reduction in heat release rate, mass loss rate and smoke generated values compared to untreated radiate pine.

    摘要： A wood chip material, especially a fireproof water resistant wood chip material, especially a fireproof water resistant wood chip material to make oriented strand boards which consists of a mixture containing 30 to 43 weight percent of wood chips, 53 to 61.9 weight percent of an aqueous solution of silicate, 2 to 5 weight percent of aluminium hydroxide, 1 to 3 weight percent of water, 0.1 to 1 weight percent of a stabilizer of the aqueous solution of silicate, and a hardener of the aqueous solution of sodium silicate in the concentration of 0.5 to 5 weight percent to the pure aqueous solution of sodium silicate providing always that the density of the aqueous solution of sodium silicate ranges from 1370 to 1400 kg/m3 and the SiO2 to NA2O molar ratio in the aqueous solution of sodium silicate ranges from 3.2 to 3.4. A method of production of a wood chip material, especially method of production of a fireproof water resistant wood chip material, especially method of production of a fireproof water resistant wood chip material to make oriented strand boards according to which, as the first step, the aluminium hydroxide is mixed with water, then wood chips are added into the mixture and everything is stirred thoroughly in such a manner that a wood chip mixture is formed, then the stabilizer of the aqueous solution of sodium silicate is added in the aqueous solution of silicate and after that the hardener of the aqueous solution of sodium silicate is admixed in this solution. Then the solution is stirred for 1 to 10 minutes until a binding solution is formed. Then the wood chip mixture is poured, at continuous stirring, in the binding solution and everything is stirred thoroughly again. Then the resulting mixture is poured in the place of application.

    摘要： Disclosed is a method for preparing a hydrophilic writing sliced bamboo veneer, including, in sequence, the following steps: (1) processing a sliced bamboo veneer into thin bamboo sheets with a thickness of 0.2-0.6 mm; (2) selecting the thin bamboo sheets with less color difference and fewer processing defects, and rolling the selected thin bamboo sheets on a plane; (3) performing deburring, sanding, and surface polishing on the rolled thin bamboo sheets; (4) performing mildewproofing and mothproofing treatment on the thin bamboo sheets; (5) performing surface coating treatment on the thin bamboo sheets using a coating material; (6) drying the coated thin bamboo sheets at low temperature; (7) fine-polishing the dried thin bamboo sheets; (8) cutting the thin bamboo sheets; and (9) flattening, compacting, and piling the cut thin bamboo sheets for future use.

    摘要： The invention relates to a wood-based biomimetic artificial muscle and preparation method and application thereof. The biomimetic artificial muscle comprises a wood-based cellulose skeleton, and polyvinyl alcohol and at least one ionic polymer filled in the wood-based cellulose skeleton. The preparation method includes S1: slicing wood, and subjecting the obtained wood slices to ammonia treatment and delignification in sequence; S2: soaking in the solution of citric acid and/or citrate; S3: preparing water solution of an ionic polymer and DMSO water solution of polyvinyl alcohol separately, and mixing to obtain polymer solution; S4: subjecting the treated wood slices to vacuum treatment, filling the polymer solution into the container, releasing vacuum, and pressurizing to infiltrate the polymer into the wood slices until saturation; S5: freezing the wood slices in a refrigerator and thawing; and S6: repeating S5 for 5-10 times, washing the wood slices, and drying. The inventive biomimetic artificial muscle obtained by physical crosslinking not only has the same elasticity and electrostriction as the polymer, but also maintains the strength of the wood-based skeleton.
