Definitions

the invention relates to a method for producing a wood-based panel, in particular a wood fiber board, in which a cake sprinkled with an adhesive wood fibers or wood chips scattered on an endlessly circulating conveyor belt and conveyed in a transport direction T to various processing stations, the compressed cake in a pre-press and then pressed under pressure and temperature influence in a hot press to a plate of desired thickness.
Such a method is for example from the DE 10 2005 033 687 A1 known.
first long fibers must be produced in a defibering cut, which can be done in an upstream process or immediately before the plant for producing the wood fiber boards.
the coarse, long wood fibers are then applied with additives, such as flame retardants and water repellents.
binder urea-formaldehyde glue
the fibers are then dried with appropriate additives and the fiber sizing via a power tube dryer.
the fiber mixture is sprinkled on a spreading device to an endless cake on the endless circulating conveyor belt.
the loosely sprinkled mixed fiber cake is then fed from the conveyor belt to a cold pre-press and cold pre-compaction of the fiber web is achieved. Subsequently, the nonwoven fabric is returned to the conveyor belt of a continuous hot press in which it is hot pressed to a plate of desired thickness.
the press belts are advantageously coated with a release agent to prevent adhesion of the prevent plates formed.
the endlessly produced plates are then formatted and separated into individual plates and then assembled.
MDF Medium Density Fiberboard
HDF High Density Fiberboard
properties may be, for example, the conductivity that is involved or desired for a fiberboard either in powder coating the panel itself or when the panel is to be used as a laminate flooring panel support and the flooring must have antistatic properties.
the conductivity can be achieved by adding salts in the manufacturing process, for example in the refining process.
Another desired property may be a fire retardant design.
the method described above is to be improved so that a quick and safe impregnation of the wood-based panel with various impregnation is possible.
a generic method is characterized in that the cake on the conveyor belt behind the pre-press and before the hot press is exposed to a vacuum, and at the same time an impregnating medium is applied to the fiber cake, which is distributed due to the vacuum in the fiber cake.
the impregnation takes place at a time within the manufacturing process, to which a high porosity of the surface is still present, which means that the impregnating medium can be easily sucked into the cake and evenly distributed there.
the vacuum is applied underneath the fiber cake and the impregnation medium applied to the fiber cake from above.
the impregnation medium can be liquid or powdery.
the impregnation medium is liquid, it can be sprayed onto the fiber cake by means of nozzles.
the device for applying the impregnation medium can be arranged stationary, which simplifies the construction of the production line and reduces its cost.
the impregnation is applied at least partially.
areas are created with / without impregnation (tempering), the tempered areas having deviating properties in relation to non-tempered areas.
the impregnation medium can influence, for example, the water absorption capacity or the strength values of the finished-pressed wood-based panel.
the impregnation station preferably consists of a vacuum station arranged below the conveyor belt and an application unit arranged above the conveyor belt for an impregnating medium.
the conveyor belt has vacuum channels, which are preferably produced by a perforation, laterally next to the conveyor belt in the transport direction extending over the length of the impregnation station extending sheets are provided for lateral limitation of the vacuum.
the application unit is preferably arranged stationary and in particular preferably formed by nozzles.
the number of nozzles is determined by the nature of the desired impregnation.
the nozzles may be arranged parallel to one another over the full width of the chip or fiber cake or only partially, for example at the edge.
the wood fibers or wood chips wetted with a glue are sprinkled onto the conveyor belt 2, which is endlessly driven in the transport direction T, to form a cake 6.
a glue preferably a urea-formaldehyde glue
the cake 6 is compressed, so cold pre-compressed.
an impregnation station 4 is integrated, consisting of a below the conveyor belt 2 arranged vacuum station 12 and one above the conveyor belt 2 arranged application unit, such as nozzles 7, 8, consists.
the vacuum station 12 and the application units 7, 8 are stationary and immovable.
the conveyor belt 2 is perforated, so that vacuum channels form, by means of which the impregnating medium sprayed onto the upper side of the compressed cake 6 can be sucked by the vacuum station 12.
Side of the coating units plates 9, 10 are provided, which limit the cake 6 side and ensure that no air from the side can be sucked into the cake 6.
the metal sheets 9, 10 preferably extend over the entire length of the impregnating station 4.
the metal sheets 9, 10 are part of a closed frame 11 which encloses the impregnating station 4 to the outside and the vacuum station 12 receives as well as the application unit.
two nozzles 7, 8 are exemplified for the application unit.
a desired number of nozzles in the desired distribution be provided within the impregnation station.
the conveyor belt 2 runs over an air-permeable frame part 13.
impregnation medium fire retardant particles as well as insect repellent protective particles can be used. Also, colors can be used as the impregnation medium to colorize the cake 6 targeted.
a heated impregnating medium By applying a heated impregnating medium, the cake 6 can be heated and thus the production speed can be increased. For heating the cake 6 also heated air can be entered.
