Definitions

  • the invention relates to a method for producing wood-based panels, in particular of fiberboard in the semi-dry process according to the generic term of claim 1, 2 and 3 and a system for performing the The method of claim 28.
  • Fiberboard which are produced in the semi-dry or wet process, have a very low adhesive content of about 0.5 - 1%, or some fiberboard are produced entirely without glue.
  • Fiberboard from the semi-dry and wet process are so far only pressed on discontinuous multi-level systems.
  • a large falls during the production of fiberboard using the wet process Amount of polluted waste water, on the one hand when fleece is formed over a Fourdrinier wire and secondly during hot pressing.
  • This method was further developed to the semi-dry process in the 40 and 50 years, to reduce waste water pollution.
  • There are a number of Intellectual Property Rights U.S. Patent 2,757,115; U.S. Patent 2,757,148; U.S. Patent 2,757,149 and U.S. Patent 2,757,150).
  • a small amount of water is also used in the Semi-dry process from the mat at the start of hot pressing squeezed.
  • the pressing time is, for example, for a 3 mm fibreboard about 4 minutes, which is just under 1 minute in the dry process. So that the capacity of the system is sufficiently large for operation, the Multi-daylight press due to the long pressing time very many floors (up to 35 pieces). Due to the high number of floors, the presses expensive. The operating costs of such a system are due to the Multi-day press also very high.
  • the fibers With the semi-dry process, the fibers must be dried so that they become one without the use of a wire Fiber mat can be molded. At higher humidities the fibers are matted so that pneumatic or mechanical scattering is not possible is. After spreading, the fiber mat is continuously pre-pressed and in individual fiber mat sections according to the floor size using a Split saw. These mat cuts are on sieves or Metal wire mesh, which are often still mounted on metal sheets, in the Feeding basket transported where they lie for different lengths depending on the floor.
  • the fiber mat sections are often heated to a moisture of around 18% dried and after the pre-press, water is applied to the top of the fiber mat sprayed.
  • the fiber mat moisture rises in front of the press through the water about 32%. Since at the beginning of the pressing the water is only on the Top is located and therefore the top warms up faster than the Underside, the fiber mat top becomes stronger at the beginning of the pressing plasticized as the bottom.
  • the screens and sheets are made after pressing transported around the press or under the press back to the molding strand, which takes a few minutes. In addition, the screens in some plants be cleaned with water. During transportation and cleaning cool the screens and trays. You then have to press on at the beginning the heating plate temperature of 190 ° C, including 20 - 60 Seconds are needed.
  • a high specific pressure of 5.5 to 6 N / mm 2 is applied to the fiber mat at the beginning of the pressing.
  • a small part of the water is squeezed out of the fiber mat.
  • the water is transported through the sieve to the fiber mat narrow surfaces and then runs down from the press plates.
  • the density of the outer fibreboard layers is also defined in this phase. Due to the uneven plasticization, the density on the outside of the plate facing away from the screen is higher than on the outside of the plate facing towards the screen.
  • the density profile of the fiberboard produced in this way is therefore usually asymmetrical, which in some applications leads to disadvantages due to a warping of the board. If the fiberboard absorbs or releases moisture, it swells or shrinks more on one side due to the asymmetrical density profile and warps as a result.
  • the specific pressure is reduced and the fiber mat is dried to about 8% moisture in 2-4 minutes, the steam being removed via the sieve.
  • the specific pressure is usually set so that it is slightly higher than the vapor pressure in the fiber mat. This prevents the fiber mat from bursting in the press.
  • the fiber mat is compressed to a final pressure with a specific pressure of approx. 3 N / mm 2 and dried to approx. 2% moisture. It is not possible to regulate the travel of the individual levels, so the fibreboards have high thickness tolerances.
  • the invention is based on the object of specifying a method and a method To create plant with a fiberboard with little or no glue is producible and with which the pressing time can be drastically reduced, and improved the properties of the plate and the thickness tolerances of the plate become.
  • step according to claim 3 is by water spraying a simple and inexpensive preheating of the fiber mat for Fiberboard ⁇ 4 mm can be produced.
  • the system for carrying out the method according to claim 28 consists in that as a press a continuously working press with the press pressure transmitting and the fiber mat through the press nip endless Steel belts exist, the steel belts over drive and deflection drums the upper frame part and the lower frame part are guided all the way around with adjustable press gap over moving, with their axes transverse to Belt running direction of the guide rods opposite the upper frame and Support the lower part of the frame, with the roller bars at both ends in Guide chains are guided that in front of and between the spreading station and the continuously working press several on the conveyor belt and to the Surfaces of the fiber mat directed hot water spray devices and Means for applying release agents are arranged from the continuously working press with a pre-press Steam preheating device and upper and lower screen belt is provided, the continuously working press as storage for the fiber mat and for Water and steam discharge from the fiber mat one made of rustproof Material existing, guided with the lower steel band, Endless metal tape that has before entering the press nip is guided over a heating plate and the lower steel strip for de
  • the pressing time can be significantly reduced compared to the known intermittent dry drying method.
  • the pressing time for a 4 mm thick fiberboard is reduced from 4 minutes to approx. 1 minute (see Table 1).
  • a major advantage is that the preheating of the fiber mat to at least 100 ° C drastically reduces the heating time of the fiber mat. At this temperature, the viscosity of the water drops, which reduces the flow resistance and allows the water to be squeezed out of the mat more quickly. Steam preheating of the fiber mat to 100 ° Celsius is particularly advantageous in the production of fiberboard with a thickness greater than 4 mm, since the shortening of the pressing time is particularly high.
  • the table shows selected process parameters during hot pressing in a continuous press according to the inventive method for a 4 mm thick fiberboard.
  • phase Time [seconds] Sp. Pressure [N / mm 2 ] start-end Humidity DS [%] start-end Moist MS [%] start-end Temperature MS [° C] start-end 1.

  • the continuous press In contrast to the production in multi-daylight presses, the continuous press the fiber mat even with a higher one Hot plate temperature than 190 ° C, since the pressing time is shorter and the fiberboard can be cooled at the end of the pressing. This will the pressing time is significantly reduced.
  • the multi-daylight press is on the ground the danger of steam space, especially the upper surface layer, the raising of the Press plate temperature not possible.
  • the fiberboard at the end of the Continuous pressing is cooled to around 110 ° C, the danger of Coverage burst significantly reduced.
  • the continuous press preferably carried out in this way is that very large deformations per meter of press length in the direction of transport possible are. This allows the press nip to optimally match the individual phases be adjusted. So the press nip can go so far during drying be enlarged so that surface bursts are just avoided. This reduces the flow resistance perpendicular to the surface in the fiber mat and the fiber board can be dried more quickly. As well the fiberboard can be pressed at the end of an optimized program be relieved.
  • the moisture of the fiberboard must not be below 2% be reduced, which on the one hand shortens the hardening phase and in the later air conditioning of the plate is advantageous.
  • the fiberboard has immediately after the continuous press a more even one Moisture distribution across the panel cross-section.
  • the continuous pressing according to the invention also leads to significantly reduced electrical and thermal energy costs. For discontinuous pressing, loading and emptying, about 70% more electrical energy per m 3 of fiberboard produced is required compared to the continuous process according to the invention, since a significantly higher connected load has to be installed. Since the multi-day press including the required screens has higher radiation losses, more thermal energy is also required to operate the press. In addition, on a multi-daylight press, pressing is carried out on average with higher press plate temperatures. Since the temperature of the continuous press is significantly reduced towards the end of the pressing, less water is required and evaporated from the fiber mat, thus bringing less energy into the fiber board. Furthermore, steam with a low steam pressure below 3 bar can be used for steam preheating, which is available as very cheap steam from fiber processing. This also reduces the cost of the heating energy at the start of the pressing.
  • fiber-fiber bonding is achieved in two ways: on the one hand via a so-called hydrogen bond, especially the Wood components cellulose and hemicellulose and the other about the softened lignin.
  • a so-called hydrogen bond especially the Wood components cellulose and hemicellulose and the other about the softened lignin.
  • the fibers are already plasticized at the beginning of the pressing and thus very flexible, which creates more contact areas between the fibers during of the first compression. They become less when compacting zerquescht. They nestle close together and are easier to get in Press cavities.
  • the transverse tensile strength of the fiberboard is thereby same adhesive content slightly better than without steam preheating and also the irreversible springback in the thickness swelling is reduced.
  • the wood chips are preheated at a higher temperature than 180 ° C, preferably 190 to 220 ° C, pre-steamed in preheating to achieve that substances are formed in the wood through transformation processes that lead to better bonding during hot pressing.
  • the formation of furfural is caused by the formation of acids in the Promoted preheater.
  • the formation of acids is due to the high temperature assisted in preheating.
  • Furfural promotes condensation reactions between the wooden components. Possibly can with the preheating or the refiner Acid - such as sulfuric acid - are added, which also the Promotes formation of furfural. With deciduous trees usually more sticky substances formed than in conifers. Therefore are suitable for this process hardwoods particularly well.
  • the fiber mat can be scattered using a single scattering machine, or the fibers are divided into coarse and fine fibers after production in the refiner or are already produced separately using two refiners.
  • the coarse fibers are then preferably scattered into the middle of the fiber mat as the middle layer and the fine fibers as the top layer.
  • the fibers must not be used to carry out the method according to the invention Dried under a humidity of 16% or the fibers must not below a humidity of 16%, otherwise they will horny. calloused Fibers only form an insufficient hydrogen bond. The means that care is also taken during the transport of the fibers must not fall below the humidity. Because during transportation the fiber in the air stream with air of a relative humidity that is lower than the equilibrium moisture content of the fiber, the fibers must release moisture quickly either the transport air is conditioned by, for example, steam injection or the fibers should be a little bigger after drying Have moisture than on the ribbon.
  • the moisture of the fiber mat is dependent on the steam preheating the preheating depth increased by the condensation of the water vapor. If the entire fiber mat is heated, the mat moisture increases about 7%. If about 50% of the mat is heated, it will be Humidity increase about 4%. The process must definitely be controlled in this way that the fiber mat moisture is not under at the beginning of the hot pressing 25% and not more than 35%, because if the humidity is below 25%, insufficient wood glued joints can be formed. Then the glue consumption increases very much. If the humidity is over 35% on the other hand, the pressing time is extended due to the longer Drying phase very strong.
  • the water in order to achieve a closed fiberboard surface with a high density and to protect the steel strips from contamination, it is advantageous to spray water in a quantity of 20-700 g / m 2 onto the fibrous mat surface, depending on the consistency of the fibers and the fiberboard thickness.
  • the water can also be sprayed onto the conveyor belt or onto the screen belt during steam preheating. It is also favorable to spray release agents onto the fiber mat surface and / or the conveyor belt so that the fibers do not stick to the metal fabric belt during preheating, the conveyor belt, the steel belts and the metal fabric belt in the continuously operating press.
  • the amount of water that is sprayed on before steaming must not be so large that there is free water on the surface of the fiber mat, since there are problems with steaming due to uneven condensation of steam and uncontrollable conditions.
  • a larger amount of water than 60 g / m 2 can only be sprayed onto the fiber mat after steaming in the pre-press with steam preheating.
  • the water should preferably be heated to temperatures of 60 - 95 ° C before spraying. Since the residence time of the water from spraying to contact with the fiber mat with the steel strip in the continuously operating press is very short, this water is almost not absorbed by the fibers and thus has only an insignificant influence on the density profile. It is also advantageous if the water is only sprayed onto the fiber mat from above. The water is then evaporated immediately upon contact with the steel strip and can only flow vertically into the fiber mat.
  • the steam formed does not penetrate the fiber mat. After evaporation, the steam flows over the metal fabric belt from the press against the transport direction in the direction of the inlet and across the transport direction to the press edge. The moisture of the fiber mat is then not increased and the pressing time is not shortened. A larger amount of water must not be sprayed onto the side of the fiber mat that faces the metal fabric band, since the moisture of the fiber mat would then not be increased and the pressing time would not be shortened.
  • the fibers have to be moist can be dried, plus the moisture due to the vaporization, the Water spraying and water from the release agent application inside of the above range.
  • To the moisture input into the individual Controlling fiber mat layers precisely requires the amount of sprayed on Water and the amount of steam added for the top and bottom
  • the fiber mat side can be measured separately.
  • the amount of steam that is used Heating of the sprayed water and the water absorbed by the wood is required can be determined from the water temperature and the sprayed Calculate the amount of water.
  • the amount of steam needed for heating of the fibers is required from the initial temperature and the humidity of the Fibers are calculated.
  • appropriate measuring devices - such as microwave measuring devices - can Moisture distribution over the fiber mat cross section can also be measured. Knowledge of the moisture and the moisture distribution over the Cross section of fiber mat immediately in front of the continuously operating press is both for the formation of a sufficient bond and one minimum pressing time important as well as for the formation of the bulk density profile significant. For a short pressing time, the fiber mat is cheap vaporize the entire cross section and as much hot water as possible on the Spray fiber mat.
  • the amount of water sprayed and Control of the metal mesh belt temperature or the upper and lower Hot plate temperature in the continuously operating press should do that Raw density profile of the finished fiberboard immediately after the continuous working press can be measured.
  • Fiberboard from the Semi-dry processes often do not show a significant decrease in density in the Center of the fibreboard. Fiberboard produced in the dry process shows a Minimum density in the middle of the fiberboard, which leads to higher bending strengths leads with the same use of materials. It has now been found that after the method according to the invention fiberboard with similar density profiles, how they are produced in the dry process can be produced. For this, the entire cross section of the fiber mat should not be preheated with steam and are softened, just the top layers.
  • the transverse tensile strength of the method according to the invention produced in the laboratory Fiberboard is slightly lower on the fiberboard edge than in the Fibreboard middle. This is caused by the curing temperature is slightly lower at the edge. The curing temperature is in the fiber mat lower because of the steel straps, the press plates and the roller bars on the edge are cooler than in the middle of the press. They cool through the escaping water and the circulating air. Generally the press plates are 50 mm each Press side wider than the fiber mat. It has now been found that by increasing the distance from the edge of the press plate to the fiber mat ⁇ 100 mm the curing temperature at the edge is higher and the transverse tensile strength the fiberboard at the edge can be improved significantly. In addition, the Fiber mat strewn on the edge with a higher basis weight be, which also achieve an increase in transverse tensile strength leaves.
  • the continuous strand of fiberboard produced according to the invention is after a format division - as with the conventional semi-dry process - after-treatment to improve the properties.
  • the fiberboard is passed through a heat channel or in warmly stacked in a heated hall.
  • heat treatment of the Fiberboard at temperatures between 110 ° and 200 ° C after the Continuous press is used to bond the individual fibers increases, which improves the bending properties and the swelling values.
  • the fiberboard can be warm be stacked or pulled as a package through a heat duct.
  • the metal fabric tape in the continuously operating press has the Function, a drainage and evaporation of the fiber mat too enable.
  • the metal fabric tape must therefore have a structure that a removal of water and water vapor within the Structure perpendicular to the direction of transport without large flow resistances allows. That means that within the metal fabric band across Transport direction there is a larger free cross-section.
  • Through the Use of the metal cloth tape can be the continuous one Press also run in a width of over 4 m because of the fiberboard is dewatered and evaporated exclusively via the metal mesh belt.
  • the metal fabric tape can be a smooth or to the fiber mat side have a rough structure. Usually a smooth structure is desired if the Fiberboard should be coated later. For individual applications too a rough structure with a screen print on the plate surface favorable.
  • the steel belts at the press edge are significantly cooler than in the middle of the press, which means that they fluff towards the fiber mat.
  • the system is therefore designed so that the lower steel belt is wider than the upper steel belt and covers the guide chain for guiding the roller bars. At some points the lower steel band can then be pressed down with hold-down rollers. The water is also collected and discharged at these points. These hold-down rolls are provided from the start of the press up to approx. 20% of the press length.
  • the specific pressure is important because of the avoidance of relative movements between the metal fabric belt and the steel belt due to thermal expansion and thus the avoidance of scratches on the steel belt. Since this process mainly produces thin fiberboard, the metal fabric tape must not have thickness tolerances greater than ⁇ 0.075 mm. The thickness tolerance would also show up in the product and would lead to a larger sanding.
