摘要： Systems for attaching a plurality of wood products are provided. In a first type of system, a first wood product has a first chemical compound applied to a surface of the first wood product. A second wood product has a second chemical compound applied to a surface of the second wood product. An adduct is formed when the first chemical compound contacts the second chemical compound wherein the first wood product becomes adhered to the second wood product. In a second type of system, a pressure sensitive and/or anaerobic adhesive is placed on at least one of the wood products prior to assembly. The compounds/adhesives have an open assembly time greater than or approximately equal to 24 hours.

摘要： A process for making engineered lignocellulosic-based panels with superior strength and dimensional stability. The process comprising adding to green lignocellulosic particles a low-nitrogen content, high molecular weight, phenol-formaldehyde resin before the green particles are dried. The resin is added in an amount from about 1 to 25 weight percent based on the dry weight of the green lignocellulosic particles. The resin has a nitrogen content of from about 0 to 3%, a viscosity of from about 20 to 2000 cps at 20° C., and a molar ratio of formaldehyde/phenol of from about 1.2 to 3.0. The green lignocellulosic particles treated with the resin are dried until the particles have a moisture content of from 1 to 8%. A second resin is added to the dried particles and then the dried particles are consolidated under heat and pressure to form the engineered panel.

摘要： An improved hot gas pressing system for use in manufacturing wood-based composite panels reduces in-press time substantially while reducing blistering, pitting, and warping in the final panel. Condensable steam as the preferred gas is injected into both faces of the mat after the press closes to an intermediate position compressing the mat to an intermediate density. After the steam is applied for a predetermined time period at the intermediate density quickly raising the mat temperature, a steam through step is applied after which the press is closed to its final position. Steam is reapplied to both surfaces of the densified mat to maintain temperature further reducing cure time of the adhesive after which venting and vacuum steps are applied to both surfaces of the mat to reduce internal pressure and remove moisture from the mat prior to opening of the press.
