Definitions

  • the invention relates to a building material using of bast fibers and a binder as well as a process and a device for producing this building material.
  • the wood fragments of bast fiber plants are used as shives referred to when separating the bast fibers originate from the woody core.
  • the stalks in full length or in stalk sections corresponding Devices fed to the brittle wood core in Break fragments and the bast fiber from the wood to solve.
  • By "swinging" or “tangled fiber roads” with subsequent machines for cutting off remaining bars the fibers then either become almost shave-free Long fiber or a tow with a certain Residual bar portion generated.
  • the fibers After deforestation, the fibers must cost several Subjected to cleaning and opening operations become. They will inevitably be cut supple and soft. Nonwovens made of soft fibers but sink together. Since it is too tight they can only be melted by thermoplastic soak heavily and unevenly. This is also true for the spray or pouring of thermosets synthetic or biological type. As a fleece for insulation materials they lose a part by slumping together of their insulation value. It therefore needs synthetic fibers to be mixed in with their brittleness Prevent collapse.
  • cockroaches are extremely light wood, almost as light as balsa wood. They are stiff and brittle and have a fiber structure. Their density is in the range between 250 and 350 kg / m 3 . After breaking, they are not very slim.
  • fibers from bast fiber plants also short fibers, have a very high strength and a very high degree of slenderness.
  • bast fibers and shives are always separated thoroughly, since shives are disruptive for the most part of the machines and technologies currently available for the production of nonwovens, mats and balls, as well as for spinning, as well as for currently known products Make processing impossible.
  • the invention is based, so far economically use shives regarded as waste and in the production of building materials and components use.
  • the fibers are laterally irregular from the shives from.
  • the shives have Lengths between 2 and 50 mm and those with the shives partially connected fiber lengths between 2 and 100 mm and the loose fibers lengths between 2 and 80 mm.
  • the fibers can be crimped in shape exhibit.
  • a device for performing the method is specified in claim 12.
  • the fibers 19 are only partially, if predominantly, detached from the shives 18.
  • the fiber lengths are specifically in the range from 5 to 100 mm.
  • the fibers 19 which are not completely detached from the shafts 18 protrude laterally.
  • the tangled structure of the fiber 19 can be specifically reinforced. While shives 18 cleaned from short fibers have bulk densities between 90 and 120 kg / m 3 , depending on the type of dismantling, the bulk density can be reduced to 15 kg / m 3 with only partial deforestation. Shavings cleaned from fibers lie largely parallel to each other due to their natural longitudinal axis.
  • a mixture of shives and fibers results in a fairly non-directional, i.e. an isotropic, arrangement.
  • fibers 19 which are not completely detached from the scraper 18, large gaps are formed according to FIG. 2 due to the tangled structure.
  • shives 18 and fibers 19 There are a large number of points of contact and intersection between shives 18 and fibers 19 in addition to the natural adhesions at the points where the bond between wood and bast fiber 19 was deliberately not broken due to incomplete deforestation.
  • the 3 is a mechanical via a box feeder 2 Feeder 1 in the form of a circulating belt arranged.
  • the feed conveyor 1 commutes over the full Width of the box feeder 2.
  • the box feeder 2 is a slide 2.1 with a comb as a layer height limiter assigned. Runs below the box feeder 2 a floor tape 3 with a scratch set.
  • the feed of the Floor belt 3 is infinitely adjustable. If through the Slider 2.1 the height of the layer is limited, so is this layer through the floor tape 3 with a scratch set milled off. The quantity is metered via the feed rate. To do so Material of sufficient height for further dissolution promote and enable fine dosing, a steep conveyor 4 with a scratch set is provided. Runs at an adjustable distance from the steep conveyor 4 a stripping spiked roller 5.
  • the material from the steep conveyor 4 is one with the steep conveyor 4 intermeshing spiked roller 6 arranged.
  • the speed of the wiper roller 6 is adjustable so that in addition to stripping or combing of the material also affects the degree of loosening can be.
  • a cleaning roller 7 which acts as a spike, Brush or fan roller can be executed. It there is the possibility of several groups of steep conveyors 4, stripping spiked rollers 5, stripping spiked rollers 6 and cleaning rollers 7 in several groups to connect in series. Following the last one A resolving-scattering head combination 8 is arranged in the group.
  • the material falling from the steep conveyor 4 is taken up by a mixing conveyor 9. On this Conveyor 9 is a loose nonwoven 17, wherein previously liquid additives and / or via a nozzle system 10 11 solid additives applied via a spreading system have been. If necessary, more than one mixing conveyor can be used 9 are arranged. Each mixing conveyor 9 is one Scraper and mixing spiked roller 12 assigned.
  • the Roller 12 can also be used as a spiked, brushed or fan roller be executed.
  • the roller 12 is more or less in layers on the mixing conveyor 9 Additive-added material to dissolve the layers and homogenization combed and swirled. Then the material on a conveyor belt 13 one Aggregate group fed largely with the Steep conveyor 4, the rollers 5 to 7 and the dissolving-spreading head combination 8 is identical. Now done the final scatter or fleece formation 17, since the Shives 18 and fibers 19 sufficient with the additives are mixed. There is also a possibility that Place material in containers or molds.
