WERKSTOFFPLATTE, VERFAHREN UND ANLAGE ZUR HERSTELLUNG EINER WERKSTOFFPLATTE SOWIE VERWENDUNG EINER WERKSTOFFPLATTE
The invention relates to a material board (1) which comprises a core (2) and a first cover layer (3) and a second cover layer (4), each of which is formed by a mixture (7, 8) formed by lignin-containing particles (5, 6) and binder, which mixture is designed to form a solid body structure in a chemical binding process. The aim is to provide a material panel, which, for ecological and economical reasons, comprises a high proportion of particles based on annual plants and still exhibits good mechanical properties. Another object of the invention can be considered that of ensuring that the system load is kept relatively low during the production process. Another object can be considered that of keeping the proportion of stock removal low. According to the invention, at least 70%, preferably at least 80%, most preferably at least 90% of the particles (5) associated with the mixture (7) of the core (2) are obtained from annual plants, and at least 70%, preferably at least 80%, most preferably at least 90% of the particles (6) associated with the mixtures (8) of the two cover layers (3, 4) are obtained from perennial plants. The invention further relates to the use of a material board and to a method for producing a material board. Finally, the invention relates to a system for producing a material board.
