Short overview on Fiberboard process
Fiberboard panels are generic term for panels primarily composed of lignocellulosic fibers as a row material combined with a synthetic resin or other suitable bonding system and bonded together under heat and pressure. A 90 % of MDF and other wood-based panel are bonded using Urea formaldehyde resin as binder. Fiberboard are commonly produced from softwood trees as a source of natural fiber, such as pine trees, widely spread in natural forests in Europe and America, besides hardwood trees that grow in the whole world, like oak, poplar, and maple besides that fast growing trees such sesbania . In NFB, sugarcane bagasse is utilized in the manufacturing of MDF/HDF panels as a sustainable raw material and date palm midribs as well.
Manufacturing of fiberboard process in NFB including raw material preparation, purification, and cleaning to get rid of wastes such as dust, sand, and metal. Clean material digestion and fiber formation through pressured refiner to obtain qualified fiber convenient for fiberboard., then glue dosing followed by drying through a blow line using a flash dryer to obtain a suitable moisture content of fiber. Mats are formed through a mat-forming machine and pressed to obtain a uniform mat with a certain size, and then mats are pressed through a hot press system to produce raw fiberboard panels. Finished boards with a certain thickness and standard sizes are produced through sanding machines to reach the smoothness for the surface of the board, then to be trimmed to reach standard dimensions. The products to be packed as pallets with plastics, protective boards and steel strips.
