Definitions

  • the invention relates to a method for the continuous production of wood-based panels according to the preamble of claim 1 and a continuously operating press according to claim 10.
  • a process for the continuous production of wood-based panels, in particular plates in the thickness range 1-9 mm, in the dry process is known.
  • DE 101 63 090 For example, such a method is described, and in particular, plates with low adhesive contents can be produced by this method.
  • DE 101 09 316 a method for the continuous production of a wood-based panel is described with very low pressing times. For this purpose, a very reactive adhesive system is used. These short pressing times result in a feed rate of almost 1000 mm / sec. Higher feed rates are currently not technically possible due to limitations on the forming belt.
  • Thin plates of wet thickness, 2 - 4 mm thick, are partly replaced by fibreboards of the same thickness from the dry process and chipboard of a thickness of about 15 mm.
  • the 15 mm chipboard absorbs about the same force as the fiberboard.
  • the thin panels are mainly used as furniture backs and drawer bottoms. With this use, they can also be coated on one side or painted. Lately, the direct painting of the plate surface is becoming increasingly prevalent. The previously necessary grinding process is eliminated. However, for economical direct painting, the panels must meet certain requirements.
  • the surface density must be above 1000 kg / m 3 and the density maximum must be directly at the Be surface. At a lower density of the paint is absorbed by the plate, resulting in the increased use of paint at a higher cost.
  • the invention has for its object to provide a method with which at very short pressing times thin fiberboard with optimum density profile, in particular a high density in the outer layers with density difference between the top and middle layer can be produced and to provide a continuously operating press for carrying out the process.
  • the plant for carrying out the method comprises a scattering station for forming a two or more layers Preßgutmatte on a continuously moving forming belt, a pretreatment device for the Preßgutmatte for adjusting the heat and / or moisture and a continuously operating press for pressing and curing the pressed material under pressure and Warmth.
  • the solution is that the press length of the continuous press is less than 11 m, the inlet section has a length of 1.3 m to 1.7 m and is articulated in the upper part, and that the upper heating plate is formed after 1.8 to 2.4 m matte contact for a relief shock widening the press nip, for which the Schuplattendicke is between 90-100 mm and is provided opposite the rolling rods with flexible Abrollplatten ..
  • thin fiberboards can be produced at shortest pressing times with high density differences between the cover layers and the middle layer, with a density of over 1000 kg / m 3 in the cover layers and less than 600 kg in the middle layer / m 3 , at an average density of the plate less than 750 kg / m 3 , are achievable.
  • microfibers in which the fiber structure with respect to the length is still preserved, but the cell walls are partially decomposed, so that the lumen of the cell is exposed.
  • the spreading of the cover layers with microfibers takes place through a separate fine material spreading machine or through a separating spreading machine.
  • these microfibers also transmit bending forces, which results in higher bending strengths.
  • Coarse fiber bundles or glue lumps are expediently dissolved before depositing and / or detected with a special device prior to scattering.
  • the paint consumption when directly painting an entire paint line depends on the location on a disk surface which has the lowest density. Targeted overpainting Low surface density areas are not possible. To achieve a low paint consumption, therefore, the plates must have a consistently high density both across the width and over the length in the plate surface. This is achieved if over the width in the inlet region of the specific pressure is applied almost uniformly.
  • the claimed in claim 12 continuously operating press a very flexible system is created, with which it is possible to produce fiberboard in the thickness range of 1-9 mm with optimum density profiles. For a correspondingly accurate distribution and flexibility on the way the Press length necessary.
  • the mat is first compressed in the inlet to the finished plate thickness or slightly below finished plate thickness.
  • the maximum compressive stress is applied to the mat and the height of the top layer density is formed.
  • the height of the cover layer density is influenced by the compressive stress as well as the humidity and the temperature of the respective mat layers. Only with an optimum combination of 9% humidity and a high temperature, a high density can be achieved.
  • the path must be maintained or slightly relieved to prevent further mat layers being further compacted by moisture and temperature increase.
  • the mat After forming the cover layer maxima in the desired width, the mat must be relieved as quickly as possible so that only a compressive stress of less than 0.5 N / mm 2 is applied in order to prevent further surface-near mat layers from being compacted.
  • This is possible with the inventive method and the system by means of the relief shock and the soft heating plates with a thickness between 90 and 100 mm, which is arranged according to the invention 1.8 to 2.4 m after mat contact.
  • the relief shock can be constructively designed so that a relief of up to 2.5 mm is possible, with the bending with these soft heating plates and abutting rolling plates after DE 40 10 308 and by means of an ankle joint between two hot plates on a very short distance is reached.
  • the heating plates are designed very flexible after the inlet to the discharge shock. It can therefore be relieved immediately after the enema more than other double belt presses or the distance can still be maintained until the discharge shock to achieve an even higher and wide top layer peak.
  • the high flexibility of the heating plates in this area thus make it possible to design the profile density profile in the outer layers in a wider range than before.
  • the press is provided with a relief shock of this size, a very large distance can be relieved faster at the right time than in other double belt presses.
  • a U-shaped density profile ie a very rapid drop in the cover layer density to the middle layer density can be achieved.
  • the compaction to the final size of the plate (secondary compaction) is carried out after heating the center of the mat to about 100 ° C. Depending on the press speed and plate thickness, this time or the distance from the beginning of the press will be different. Since the press is very short, the second compression must also be carried out over a short distance. In order to get the necessary flexibility in this area, the heating plate must be made under 100 mm thickness and the frame distance reduced to about 1000 mm. As an alternative or as a supplement, the heating plate also be subdivided and the shocks are executed from about 5 m as impact shocks.
  • the load impacts are preferably arranged after 5 and 7 m.
  • the temperature of the steel strips in contact with the mat must be above 140 ° C, preferably 155 ° C, so that at the time of maximum pressure sufficient heating of the mat surfaces has taken place. If the mat was sprayed, the water with high enthalpy of vaporization must be evaporated in a very short distance. Therefore, the press must be equipped against the environment, but especially with good insulation of steel strip and rolling rods in the return. An inlet drum heating and a roll bar preheating is also beneficial. These measures are necessary in one-sided paintable plates only in the upper press body.
  • the steel strip temperature should preferably can only be set higher in the inlet, otherwise the pressing time increases with a lower heating plate temperature of the underside.
  • the heating plates need to be equipped with only one heating circuit, as with the thin plates and the short press a large temperature difference along the heating plate is not necessary.
  • Directly painted panels require a very smooth surface. Foreign matter, glue lumps or local scattering often increase the specific pressure locally to a few centimeters in the press. These pressure peaks lead to dents in the steel strip in the area of the maximum pressing pressure. The indentations considerably reduce the value of directly paintable panels.
  • the steel strip can be made as thick as possible. At present, steel strips with a thickness of 3 mm can be delivered without any problems. The thick However, steel strip only has to be used at the top if the board is to be painted on one side only. As a further measure, the heating plate can be made softer in the region of maximum pressure. For this purpose, small cylinders are arranged over the entire Schuplattenbreite, yielding to the pressure at a small distance.
  • the press With regard to the transverse deformation, the press must have approximately the same press nip thickness in the inlet region across the width, as a result of which the specific pressure across the width is also almost constant. Due to the constant sp. Pressure across the width of the cover layer is formed evenly across the width. Since the plate thickness differences are not very large, production is easily possible at the beginning of the press with a setting of the press nip across the width. This setting can be made, for example, by inserting the hot plates. At the press outlet, however, a possibility of the transverse deformation of the heating plate must be provided for the exact thickness adjustment across the width. This can be done for example by means of multipots.
  • the attachment is in FIG. 1 shown in side view.
  • the scattering station is either a three- or a Zweietzmaschinellpressgutmatte sprinkled on the gas-permeable mold belt 6, then introduced with the forming belt 6 via the inlet gap 19 in the continuously operating press 3 and pressed there to a fiberboard 5.
  • the pressed material mat 4 is preheated with steam and / or sprayed with water.
  • the continuous press 3 consists in its main parts of the upper frame part 7, the lower frame part 8 and these connecting racks 20.
  • heating plates 13 and 14 by means of hydraulic cylinder piston units (not shown) against the lower Heating plate 12 up and down and locked in the selected position.
  • Preßgutmatte 4 by the continuously operating press 3 is a steel strip 9 to the lower frame part 8 and in Steel band 10 around the upper frame part 7 circumferentially arranged and guided.
  • the steel belts 9 and 10 are thereby pulled by drive drums 21 and 22 through the press nip 23 and initially deflected by inlet drums 17 and 18.
  • the steel strips 9 and 10 are also circumferentially provided each one of rolling rods 16 forming roll bar carpet.
