The present disclosure relates to a system and method for manufacturing particle board from waste-wood powders and composition of particle board. In more detail, the system is used to develop environment friendly Bakelite or wood for decoration and construction boards, furniture boards, or for external wall insulation, or in boards used in the printed circuit board industry, copper foil substrate industry processes, or in the general use of Bakelite.
In general, conventional wood-based fibreboards are made by wetting a binder (adhesive) such as a liquid synthetic resin with a fibrous substance such as pulp generated by defibrating and washing a powdered substrate. Following that, it is manufactured through dehydration, forming (forming), and press-moulding with a hot press. In terms of weight reduction and the like, such a wood fibre board has a reasonably low specific gravity, but it also has a poor mechanical strength, such as bending strength, and a low surface hardness.
Furthermore, the surface shine or smoothness is low. As a result, a surface material is bonded to the surface to improve the strength or improve the surface quality. Furthermore, a wood-based laminated board and a composite board are often made by wet laminating a wood chip material treated with a resin and a wood-based powder treated with a resin into an appropriate layer, shaping, and then applying heat and pressure using a hot press.
Moulding is used to make it, a hardwood laminate, composite board is typically made up of core material and surface material, or core material, intermediate material, and surface material are independently prepared to minimise weight, or they are laminated and integrally moulded. Alternatively, the surface material layer, the intermediate material layer, and the core material layer may be laminated on an appropriate layer, formed, and then moulded by heating and pressing with a hot press.
In one prior art solution (JPH11300711A), a wooden resin moulded article and material for it is disclosed. To provide a wooden resin moulded article prepared by moulding a powdery or granulate material containing a thermosetting resin comprising a ground product of a wooden waste material and a thermosetting resin represented by phenol resins as raw materials.
In another prior art solution (KR20020019815A), a method for producing a particle board using waste melamine and a phenol resin cosmetic plate is disclosed. The low-pressure melamine cosmetic sheet is dried sheet after impregnating raw paper (Raw Paper, Deco Paper) with phenol resin (Phenol Formaldehyde resin), melamine formaldehyde resin, and urea resin (Urea-formaldehyde resin), Is used as a product to improve the function and aesthetic appearance of the panel surface by attaching it to the panel surface with pressure at high temperature.
