ADDITIVE-CONVEYING LAMINATE LAYER
20230311446 · 2023-10-05 ·

A manufactured wood panel or board with an integrated conveying laminate that conveys a fire resistant (FR) additive to specific locations within the panel or board during the manufacturing process, and the process and system for producing a panel or board with an FR conveying laminate. The laminate may be a natural or synthetic material with a closed (i.e., solid) or open (i.e., mesh-like) surface. In addition to providing resistance to fire spread and fire combustion, the laminate also may be selected from a group of materials that produce desired structural properties (i.e., minimize cracking, enhance structural integrity) both before and during a particular event, such as a fire event.

FUNGAL MYCELIUM FIBERBOARD AND ITS PREPARATION METHOD

A method of preparing fungal mycelium fiberboards is provided. First, 1-2 year-old fungal mycelium with a water content of 50-70% is cut into 2-3 cm lengths to obtain cut fungal mycelium. The cut fungal mycelium is then high-pressure steamed to soften it, resulting in the steamed fungal mycelium. The steamed fungal mycelium is mechanically defiberized into fibers and adhesive is added to obtain adhesive-applied fungal mycelium fibers. The adhesive-applied fungal mycelium fibers are then dried at 120-160° C., resulting in dried fungal mycelium fibers. The dried fungal mycelium fibers are then spread, leveled, and pre-pressed to obtain fungal mycelium fiberboard blanks, which are hot-pressed to form the final fungal mycelium fiberboard. This method uses low-cost, fast-growing fungal mycelium as a raw material, which replaces wood chips. The preparation process is simple and easy to promote. The resulting fungal mycelium fiberboard exhibits excellent performance in various indicators and is also environmentally friendly.

Making profile-edge construction board

Construction board is made by first hot-pressing particles in a continuous belt press to form a longitudinally extending, continuous and hot composite strand that is conveyed downstream from the press. Before substantial cooling of the boards and while it is at a predetermined temperature above ambient temperature, an edge of the strand is profiled into a nonsquare profiled contour. Then the strand is transversely severed to form a succession of boards.

No-added formaldehyde binder for composite wood product and the composite wood product manufactured by the same

Disclosed a no-added formaldehyde composite wood product binder, a no-added formaldehyde composite wood product manufactured by same, and a preparation method for the composite wood product. The no-added formaldehyde composite wood product binder comprises an agent A and an agent B. The agent A is an isocyanate-based binder, and the agent B is an aqueous dispersion of polyester based aliphatic polyurethane and/or a modified polyester-based aliphatic polyurethane. The no-added formaldehyde composite wood product is formed under hot-pressing after a wooden and/or straw material is mixed with the no-added formaldehyde composite wood product binder. The composite wood product manufactured by the no-added formaldehyde composite wood product binder has excellent water-proof and mechanical properties and a good saw cutting performance, and the amount of isocyanate used is also reduced, thereby reducing costs.
