Abstract (en)
The subject of application is a method of pulp production for producing boards. Cereal straw is fragmented to the form of blades with a length from 10 to 50 mm, which are subjected to hydrothermal treatment. Then, mass obtained in such a way is injected with the help of a feeding machine between the milling plates of the defibering unit, and pressed with the help of a screw press until obtaining absolute humidity below 50%, when mass obtained is loosened into the pulp form and dried. The method is characterized in that the cut cereal straw blades are subjected to hydrothermal treatment with water solution and lye at temperature below 50°C, where hydrothermal treatment does not last longer than 1 minute. The subject of application is also a pulp board, characterized in that it contains pulp produced with a method according to the invention and a binder.
