    摘要： The present disclosure provides an engineered wood precursor mixture. The mixture includes a wood substrate(s) and a binder reaction mixture present in a range of from 3 to 25 parts per one hundred (100) parts of the dry weight of the wood substrate. The binder composition includes an aqueous portion. The aqueous portion includes a carbohydrate-containing component, including glucose, fructose, sucrose, or mixture thereof, in a range of from 2 wt % to 85 wt % based on a dry weight of the binder reaction mixture. The aqueous portion further includes 1 wt % to 33 wt % of a base based on a dry weight of the binder reaction mixture, wherein a pH of the aqueous portion is greater than 10. The binder composition further includes a partially non-dissolved polypeptide-containing component, in a range of from 20 wt % to 85 wt % based on the dry weight of the binder reaction mixture.

    摘要： A method for producing wood material boards with reduced emission of volatile organic compounds (VOCs), including: a) producing woodchips from suitable timbers; b) heat-treating at least one portion of the woodchips at a temperature between 150° C. and 300° C. for a period of 1 to 5 hours; c) crushing the wood chips that are not heat-treated and at least one portion of the heat-treated woodchips by machining in order to obtain wood shavings or by solubilizing in order to obtain wood fibers; d) gluing the wood shavings or wood fibers with at least one binding agent; e) applying the glued wood shavings onto a transport belt while forming a multi-layered shavings cake or applying the glued wood fibers onto a transport belt while forming a single-layer fiber cake; and f) compressing the shavings cake or the fiber cake to form a wood material board.

    摘要： The method relates to a method for producing a wood material panel. The method includes the following steps: (a) scattering a multitude of wood particles to produce a particulate cake, (b) applying an adhesive to at least some of the wood particles during the scattering and/or prior to the scattering, and (c) pressing of the particulate cake under high pressure and at a high temperature, wherein a quantity of adhesive that is applied to the wood particles is varied depending on its anticipated position in the particulate cake.
