Definitions

  • the invention relates to moldings according to claim 1 containing balsa wood and process according to claim 10 for their preparation.
  • the DE-U-20 2007 007 516 describes medium-density wood fiber boards (MDF boards) made of balsa wood fibers and glue, which have a bulk density between 370 to 410 kg / cm 3 .
  • MDF boards medium-density wood fiber boards
  • Balsa wood is a very light and easy to work type of wood. In addition to its use as a raft construction and as a cork replacement, balsa wood is used by model builders for aircraft and ship models. Balsa wood, however, has the greatest importance as a core material of composite materials in sandwich construction, for example in boat, ship and yacht construction, in aviation, such as in sailing and light aircraft construction, in space travel and as a core or core material of rotor blades of e.g. Wind turbines. The good insulating properties of balsa wood are also used for insulation against heat and cold, for example, from fuel tanks. In the technical field of application, the low volume weight and the unusually high compressive strength in relation to the low raw weight are exploited parallel to the fiber direction.
  • balsa also called Kantelhölzern or Balsakanteln
  • Himholzplatte four-sided processed balsa, also called Kantelhölzern or Balsakanteln, to large blocks, for example in cross section about 600 x 1200 mm, verlelmt and then transversely to the fiber direction into plates of any thickness, for example about 5 to 50 mm, sawed and then to the exact Dickenmass ground.
  • This light end grain board can absorb very strong compressive forces over the surface, but is very unstable in itself.
  • the end grain board is glued on one side with a thin fiber fleece, knitted fabric or fabric and carved from the opposite side cuboid or cube-shaped to a thin web.
  • the prepared plate can be made in any concave or convex shape and can be a curved shape, such as a boat or buoyancy body or a ball tank, adapted.
  • Balsa wood is a natural product. Therefore, the characteristics of the balsa wood within the woods of a crop can change to sections of a tree trunk. This applies, for example, to bulk density, shrinkage, compressive strength, tensile strength, etc., and the proportion of pores may vary. Deficiencies in the trunks, such as internal cracks, so-called red-core or water-heart, fibrous tangles or mineral spots, unless removed prematurely with loss of wood, can influence the regularity of the properties of a end grain board.
  • the invention has for its object to better use the wood and molded body containing balsa wood with at least approximately the same or better properties than the natural Balsahölzer to describe and a To propose methods for their rational production.
  • the balsa wood chips are oriented according to their fiber direction or fiber orientation and the fiber profile of the individual chips can deviate from 0 ° to 30 °, advantageously 0 ° to 10 ° and preferably from 0 ° to 3 °, from a general direction of the fiber flow.
  • the deviation of the fiber profile of the individual balsa wood chips is as close as possible to 0 ° (angular degree) from a general or ideal direction of the fiber path.
  • the fiber profile of all Balsaholzs Georgne in the molding should be as parallel as possible and deviate from the axis in the direction of the fiber flow not more than 30 °.
  • the chips of balsa wood are obtained from logs whose wood, for example, have a density of 0.07 to 0.25 g / cm 3 .
  • Soft balsa wood has a density from .07 to .125 g / cm 3, moderately hard balsa 0.125 to 0.175 g / cm 3 and hard balsa 0.176 to 0.25 g / cm 3.
  • the size of the individual shavings can be, for example, from 40 to 400 mm in length, 4 to 40 mm in width and 0.3 to 2 mm in thickness for longitudinal shavings.
  • Waste chips from the processing of, for example, balsa wood panels, also end grain wood panels, may have a length of, for example 10 to 50 mm, have a width of 10 to 30 mm and 1 to 4 mm in thickness.
  • the chips are produced by peeling of logs or trunk sections.
  • the logs or trunk sections are processed, for example, in a ring chipper or knife ring chipper.
  • the logs are transported via a loading station in the cutting room. Swords placed in the cutting room hold the logs in position during the cutting stroke.
  • the wood is machined parallel to the fiber, creating rectangular chips with a smooth surface and a very low proportion of fines.
  • the shavings which are preferably used in the present invention also include the long thin flat shavings called "strands" which are peeled or cut tangentially to the stem diameter.
  • Elongated strands have, for example, a length of 10 to 15 cm, a width of 2 to 3 cm and a thickness of 0.5 to 0.8 mm.
  • the chips, resp. Strands are usually produced from fresh logs and, after machining, the chips are dried, preferably in a drum dryer. Subsequently, the shavings can be graded by sifting and sieving according to size and density, sifted and sieved and stored on a case by case basis.
  • the chips are glued in particular. For this purpose, the chips are coated uniformly with the intended amount of adhesive by pre-coating or direct coating, eg in a gluing drum, by spraying, sprinkling or dusting and mixing or by dipping.
  • the glued shavings can be - occasionally mixed from fractions of different density and / or size - processed into shaped bodies.
  • the glued chips are sprinkled or poured onto a forming line and aligned as needed by measures such as vibration, shaking, sifting in the air stream, etc. in as parallel as possible fiber flow.
  • the bedding can is carried out batchwise on a table, but is preferably carried out on a continuously moving belt.
  • the edges can be trimmed and a preliminary thickness determined by doctoring or between rollers.
  • the fill on the belt can then pass through a pressing device, such as roller pairs, a belt press, etc., wherein a pre-compression of the heaped chips takes place.
  • planks of mutually bonded chips or strands There are planks of mutually bonded chips or strands.
  • the one side edge of these planks depends on the apparatus conditions and their extent may be, for example, 10 cm, preferably 50 cm, up to 300 cm.
  • the second side edge may extend, for example, from 1 cm, advantageously from 50 cm, to 300 cm, with 10 cm to 15 cm being particularly preferred.
  • the planks can be fabricated with exactly determinable side edges and any length, ie the planks can be massively manufactured with gleich Sugardem fiber flow, stacked into stacks and glued to each other.
  • the moldings according to the invention such as end grain boards, can be cut off from the stacks of concurrent fiber flow transversely to the fiber path, as sawed off or cut off.
  • the applied pressure should be chosen such that the cell resp. Fiber structure of balsa wood is not changed or damaged, in particular, that the density of the balsa wood is not or only slightly changed by compression.
  • the pressing pressure should be set low because too high pressing pressure and the wood structure is compressed in total.

  • the novel moldings may contain adhesives in amounts of from 1 to 15% by volume, advantageously from 2 to 10% by volume and preferably from 3 to 5% by volume, based on the volume of the molding.
  • the fully reacted, such as foamed or set, adhesive has the same or almost the same density as the density of the surrounding balsa wood.
  • the reacted adhesive has, based on the density of the balsa wood surrounding the adhesive, a 0 to 20 wt .-% higher or 0 to 20 wt .-% lower density.
  • Adhesives with densities of the reacted adhesive that are 0 to 10 wt% over or 0 to 10 wt% below the density of the surrounding balsa wood are preferred.
  • Foamed polyurethane adhesives are particularly suitable as adhesives with densities in the stated range.
  • the density of foamed adhesives refers to their density.
  • the present invention also relates to a process for the production of the shaped bodies according to the invention with the features of claim 10. Preferred embodiments of the process according to the invention are described in the claims dependent on claim 10.
