摘要： In a process for the production of a flame retardant and/or strengthened fiberboard, a tailored fiberboard is charged on a processing device at first. Subsequently, a flame retardant and/or strengthening agent is applied to the top side of the fiberboard. The agent applied is sucked or pressed into the fiberboard. This is achieved by generating a pressure difference between the top side and bottom side of the fiberboard.

摘要： Wood-fiber insulation board is pressed to a uniform thickness and continuously advanced in a horizontal travel direction on a conveyor prior to subdivision into individual panels. The strength of the wood-fiber insulation board is determined by first pressing with an actuator a contact element downward at an actual pressure on a subregion of the advancing wood-fiber insulation board so as produce an actual deformation of the wood-fiber insulation board of between 1% to 7% of its thickness. Then a force sensor determines the actual pressure applied by the contact element to the board that produces the actual deformation and this the determined pressure and the actual deformation are transmitted to a central processor that extrapolates to a standardized deformation based on the determined pressure and actual deformation.

摘要： A lignocellulosic composite article includes a plurality of lignocellulosic pieces and an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. The adhesive system includes a binder component and a compatibilizer component. An example of a suitable binder component is an isocyanate component, e.g. a diphenylmethane diisocyanate (MDI), a polymeric diphenylmethane diisocyanate (pMDI), and combinations thereof. The compatibilizer component includes a trialkyl phosphate. The compatibilizer component is utilized in an amount of at least about 0.5 parts by weight based on 100 parts by weight of the binder component. The compatibilizer component is useful for reducing the amount of press time required during manufacture of the composite article. The adhesive system can include additional components, such as an isocyanate-reactive component. The composite article may be various lignocellulosic composites, such as oriented strand board (OSB), particleboard (PB), fiberboard (e.g. medium density fiberboard; MDF), etc.
