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.

The present invention relates to a fiber board product comprising fibers in an amount from 50.0 to 99.0 parts by weight (d/d), at least one particulate calcium carbonate-containing material in an amount from 1.0 to 50.0 parts by weight (d/d), at least one binder in an amount from 0.05 to 25.0 parts by weight (d/d), at least one wax in an amount from 0 to 5.0 parts by weight (d/d), wherein the sum of the fibers and the at least one particulate calcium carbonate-containing material is 100.0 parts by weight (d/d), a process for manufacturing such a fiber board product as well as an use of at least one particulate calcium carbonate-containing material having a weight median particle size d.sub.50 of 0.5 to 150.0 ?m as fiber replacement in a fiber board product, preferably in a high-density fiber (HDF) board, medium-density fiber (MDF) board, low-density fiber (LDF) board or particle board.

The present invention discloses a preparation method and recycling method for degradable and recyclable paper plastics with water resistance and high-strength. By coating cyclic carbonate and amine compounds on paper, these compounds penetrate the paper's fiber structure, followed by curing treatment, resulting in a recyclable, degradable, and reprocessed paper plastic material with water resistance and high-strength. This method involves coating only cyclic carbonate and amines onto the paper, which, after heating, yields the paper plastic. The invention offers versatility, enhancing various paper types with improved mechanical properties, temperature resistance, water resistance, and solvent resistance while maintaining degradation capability. The paper plastic exhibits excellent self-healing, plasticity, degradation, and reprocessing properties. The process method is straightforward and user-friendly, making it suitable for industrial-scale production.

The present invention is directed to methods and systems for manufacturing molded fiber products using a pulp slurry and apparatus submerged in pulp slurry. The system utilizes a vacuum and mesh shaping of the product to pull fiber from the pulp slurry to the mesh shape while sucking the water through the mesh shape. The molded fiber product is then pressed to bolster the strength and structure of the product. The product is then coated using centripetal force to uniformly spread the coating across the selected area of the product. After coating, the product is pressed again to ensure the waterproof and airproof structure of the product. The materials used in manufacturing the molded fiber product are biodegradable, and the apparatus to form the molded fiber product is shaped according to the desired shape and size of the product.

Press for making large molded pulp objects, which has a raisable and lowerable male mold half, perforated for suction dewatering after dipping into a pulp slurry. The molding surface of said male mold half is coated with an elastomer to preserve even surface contact with the molded pulp object during compression and during thermal expansion or contraction of said mold halves. Advantageous embodiments include vacuum distribution troughs beneath the elastomer layer in the male mold half, multiple wire mesh layers on top of the perforated elastomer layer, and slight lateral adjustability of the otherwise stationary female mold half.
