Definitions

  • the present invention relates to a method according to claim 1 for producing a particle-based element, in particular a chipboard or fiberboard.
  • a method generically comprises the provision of a particle mass with a multiplicity of particles and the pressing of the particle mass.
  • the international patent application discloses WO 2005/046950 A1 placing wood particles and pressing them to a particle-based plate, wherein a higher density area is achieved by placing a larger number of particles in that area.
  • a higher density area is achieved by placing a larger number of particles in that area.
  • locally increased strength over the entire cross-section is achieved from the top to the bottom of the plate.
  • the weight of the plate is significantly increased, and the overall structural stability of the plate is not significantly improved.
  • the international patent application WO 2009/050565 A1 discloses a chipboard in which the wood chip material can be replaced by larger-sized wood material in some areas, for example by larger wood fibers, wood powder, wood chips or wood flakes. Furthermore, the type of wood can be changed. It is further disclosed that material regions of different composition advantageously have a higher density than the normally compressed material regions.
  • the object of the present invention is to provide a method for producing a particle-based element which can be operated economically and enables the production of particle-based elements with tailor-made structural properties.
  • the second part of the particle mass is wavy shaped in the longitudinal direction of the particle-based element between a lower side region and a top side region of the particle-based element. Due to the different compression properties and in that a part of the particle mass forms a matrix, it is achieved that a structure can be formed within the particle-based element, which has various advantages. Thus, by such an arrangement, especially the structural stability of the particle-based element can be increased. However, it is also conceivable to produce a particle-based element by a different choice of the compression properties and / or the arrangement of the first part, which is flexible but nevertheless stable. The method is also suitable for other purposes of the targeted arrangement of materials with different properties.
  • the wavy shaping of the second part of the particle mass makes it possible to increase the structural stability of the particle-based element, since an increase in the area moment of inertia can be effected by reinforced regions outside the neutral fiber of the particle-based element.
  • the lower side region and the upper side region of the particle-based element are structurally connected by the second part of the particle mass, which can further increase the stability, especially since in many particle-based elements the upper side region and lower side region have a higher stability and hardness than the inner region of the element.
  • the particulate mass is pressed into a particle-based element having regions of different density, the particulate mass having particles of substantially the same density before pressing.
  • a region of higher density is created, whereby a targeted density distribution can be achieved in the particle-based element by a simple method.
  • the regions of higher density advantageously have a higher stability and thus allow for a slight increase in the weight of the particle-based element a substantial improvement in the structural stability.
  • the targeted design of the flexibility of the component is possible.
  • the second part of the particle mass is arranged in a continuous matrix.
  • the second part forms a structurally continuous shape in which the first part of the particle mass is arranged.
  • the second part of the particle mass thus determines the global, structural properties of the particle-based element, while the first part of the particle mass, the local properties in the range of its arrangement but also global properties such. B. affects the weight of the particle-based element.
  • the second part of the particle mass is arranged in a lattice structure.
  • a lattice structure allows a uniform distribution of the second part of the particle mass and thus in particular an improvement in the structural stability of the particle-based element.
  • the second part of the particle mass is compressed more strongly during the pressing than the first part of the particle mass. Due to the increased compression, the second part of the particle mass forms a structurally more stable element that enhances the particle-based element. Furthermore, this makes it possible with only one pressing operation to produce a component with regions of different material compression.
  • the first part of the particle mass can be compressed more strongly during the pressing than the second part of the particle mass.
  • the matrix consisting of the second part of the particle mass is not the more compressed part but the first part arranged therein.
  • the properties of the particle-based element can also be influenced in a different direction, for example by a deliberately more flexible design of the particle-based element.
  • the second part of the particle mass is further formed wavy in the width direction of the particle-based element.
  • a substantial increase in the structural stability in both the width direction and in the longitudinal direction of the element can be made possible.
  • different types of particles are disposed in the particle-based element.
  • the different types of particles may have different compression properties, but also a variety of other different characteristics, such as differences in the Density, ductility, hardness, brittleness, fracture behavior, abrasion behavior, elasticity, shape, magnetic permeability, thermal properties, particle mass viscosity, melting behavior, boiling behavior, electrical conductivity and / or light stability ,
  • a first type of particulate is conveyed and a second type of particulate is fed by a particulate feed tool to the first type of particulate before the particulate mass is pressed.
  • a different treatment of the first and / or the second part of the particle mass is performed.
  • the treatment the compression properties of the particle mass can be changed. In general, however, it is also possible that further properties of the particle mass are changed by the treatment.
  • the treatment of a portion of the particulate mass may include the introduction of a chemical agent.
  • a chemical agent is the introduction of adhesive and / or hardener to pre-consolidate parts of the particle mass and thus to change their compression properties towards less compressibility.
  • the treatment of a part of the particle mass can also be done by the introduction of water.
  • a particle mass which consists for example of wood fibers or similar fiber materials is softened by the introduction of water and thus has a higher compressibility, so that this part can be compressed more during pressing.
  • the introduction of water in a variety of organic fiber materials can lead to the release of natural adhesives, which has introduced the part of the particle mass in the water, can solidify after curing.
  • the treatment of a part of the particle mass can be done by the introduction of energy, in particular by a heat treatment.
  • the introduction of energy, especially heat can change the properties of the fibers in terms of their compressibility.
  • a bonding of the fibers can be achieved if the introduction of energy is carried out in combination with the introduction of adhesive and / or hardener.
  • the particle mass is conveyed during the treatment in the longitudinal direction and the treatment is carried out by a tool which is arranged within the particle mass, wherein the tool is moved in the vertical direction of the particle mass. It can thereby be achieved that a local treatment can take place within the not yet compacted particle mass in a targeted manner, which makes it possible, in a simple and cost-effective way, also to arrange more complex structures of differently treated regions in the particle mass.
  • the tool may extend in a waveform with respect to the longitudinal direction.
  • a foamable agent may be introduced into a first portion of the particle mass, wherein the foamable agent expands into a foam within the particle mass after pressing.
