  • the proposed technical solution relates to the field of forestry and woodworking industry and can be used in the manufacture of sheet building materials, furniture parts, etc. pressed products with sufficiently high physical and mechanical 5. characteristics and improved environmental properties, at a reduced temperature of thermal pressing.
  • the technical result which cannot be achieved by the above-described analogue, is to reduce the heating temperature of a flat layer of wood pulp, upon receipt of wood boards with 20. sufficiently high physical and mechanical characteristics.
  • the reason for the impossibility of achieving the above technical result for this analogue is the high density of the pulp components, which makes it impossible to isolate, at a reduced heating temperature, the necessary and sufficient amount of active natural 25. compounds contained in the plant components and forming a binder for making wood boards, thermal pressing process.
  • the technical result that cannot be achieved by the prototype is to reduce the heating temperature of a flat layer of wood pulp, upon receipt of wood boards with a sufficiently high physical and mechanical characteristics.
  • the reason for the inability to achieve the above technical result of the prototype is the overestimated dense wood in the wood pulp in the form of particles of chopped branches and tops of conifers, which does not allow to isolate, at a reduced heating temperature of the mass, a sufficient amount of active natural compounds 25. contained in plant components, necessary for the formation of a binder, upon receipt of wood boards.
  • the content in the wood pulp of particles with a density of coniferous wood of more than 43 wt.% - does not allow to isolate from the components a sufficient amount of active natural substances necessary for the formation of a binder and obtain wood boards with sufficiently high physical and mechanical characteristics, at 20 .
  • the temperature of the heating of wood pulp is less than 120 degrees C, in the process of heat compaction, the humidity of the wood pulp is less than 18%, reduces its ductility, strength and moisture resistance of the plates obtained from it, and the mass weight is more than 40%, also leads to a decrease in the strength and moisture resistance of the boards, 25. heating the wood pulp to a temperature of less than 58 degrees C.
  • C - significantly slows down the process of release of active substances, and the formation of a binder from them during thermal compaction of wood pulp, and wood heating mass to a temperature of more than 120 degrees C.
  • C - increases energy consumption, while evaporating and destructing the contained in it ZO. useful volatile compounds.
  • - wood pulp is obtained from crushed plant material, consisting of particles of a fibrous structure, with a content of wood particles of not more than 43 wt.%;
  • Samples were obtained according to the proposed method, with reduced heating temperatures, observing the relevant technical conditions 25. conditions and technological parameters of the prototype: pressure 2.6 -5, MPa, duration of hot pressing - 1 min / mm of the thickness of the product, cooling to Zograd.S, under pressure.
  • test results show that the wood boards obtained by the proposed method, in the process of thermal compaction of wood pulp, at a temperature of its heating are much lower than in similar technical solutions, have sufficiently high physical and mechanical characteristics.
  • lowering the temperature regime allows to reduce production costs, and also gives the product useful environmental properties in the form of a persistent aroma of coniferous forest, favorable for the environment.

Abstract

Le procédé peut s'utiliser dans l'industrie du bois pour fabriquer des matériaux de construction en forme de feuilles, de pièces pour meubles, etc., des articles fabriqués par compression thermique avec des dépenses d'énergie réduites. Pour fabriquer des panneaux en bois on obtient une masse de bois à partir de particules de matières premières broyées d'origine végétale. On forme une couche plate de masse de bois et on le compacte à une température comprise entre 58 et 120 degrés. Le produit ainsi obtenu contient des compositions naturelles dans les panneaux, qui sont conservées; l'invention permet d'obtenir des propriétés physico-mécaniquesassez élevées.
