Definitions
- the invention relates to a method for producing highly filled papers, in particular decor papers for application to a carrier material, from an aqueous suspension, wherein the suspension is applied by means of a headbox on a rotating dewatering screen, which is a turbulence generator with a plurality of juxtaposed and forming a line turbulence channels and immediately downstream of the turbulence generator is a nozzle, and the suspension is passed through the turbulence channels and through the nozzle to form a jet of suspension.
- the invention also relates to a device for carrying out the method.
- Highly filled papers contain a high proportion of fillers, which is higher than for writing and printing papers or for cardboard and packaging papers. This leads in the production of papers to special challenges to achieve the desired quality in terms of their further processing and also in terms of performance properties.
- the highly filled papers also include decorative papers.
- Decorative papers are special papers for surface finishing of wood-based materials for the production of kitchen worktops, laminate flooring, furniture and other end products.
- the decorative papers are laminated on carrier materials.
- the surface of the decorative paper is printed with patterns, such as wood imitations or with other single or multi-colored designs.
- the decor paper must have a very uniform formation, dimensional stability and smoothness to ensure the required optical properties of the finished products. For the further processing of the end products, a certain strength of the decorative papers is necessary.
- the decorative papers are impregnated with resin. Even for this step uniform properties of decorative papers are necessary to ensure a uniform penetration of the resin. Due to the increasing demands on the quality, the smallest disturbances in the uniformity of the quality of the highly filled papers, in particular the decorative papers, can lead to impairments or a limitation of the quality of the end products.
- the invention relates to a process for producing highly filled papers, in particular decorative papers for application to a carrier material, from an aqueous suspension, wherein the suspension is applied by means of a headbox to a circulating dewatering screen which has a turbulence generator with a plurality of adjacent turbulence channels, which form one row form, comprises, and the turbulence generator immediately downstream of a nozzle, and the suspension is passed through the turbulence channels and through the nozzle to form a suspension jet.
- the papers are prepared from an aqueous suspension having a total material density of more than 1.5%, a pulp density of less than 1.2% and an ash mass fraction of greater than 30%, and wherein at least 3 rows are stacked and the suspension is passed through the turbulence channels having a maximum hydraulic diameter of less than 25 mm, in particular less than 20 mm, and thereafter through a nozzle having a length of more than 500 mm, in particular more than 700 mm.
- fins are inserted between the adjacent rows of the turbulence generator which, starting at the turbulence generator, extend over at least part of the length of the nozzle.
- the solution according to the invention makes it possible on the one hand to thoroughly mix the components of the suspension and, on the other hand, to achieve a hydraulically very uniform material jet as a prerequisite for uniform drainage and sheet formation.
- the hydraulic instabilities in the suspension jet are reduced to such an extent that the flatness of the decorative paper is substantially improved. Interferences and defects in the lamination process were eliminated by the invention.
- the invention is particularly advantageous at higher throughputs of the suspension of more than 4000 l / (min * m Ar beitsbreite) and at speeds of the suspension jet of more than 400 m / min particularly advantageous, since just with increasing flow rates and speeds to achieve a sufficient Uniformity of the nature of the highly filled papers, especially decorative papers, is increasingly difficult.
- the total material density of the suspension may be up to 3% or more and the ash mass fraction may be up to 90%, preferably 50% to 80%.
- the pulp density can be reduced to 0.8% and less, in particular up to 0.6%, and less, without compromising the quality of the decorative paper web. The invention therefore makes it possible to produce a wide range of decorative paper grades with good quality.
- the suspension is dewatered through the dewatering wire and then pressed, thermally dried, and the paper web formed thereby wound up.
- the highly filled paper web in particular the decorative paper web, can be impregnated, preferably with synthetic resin. As a result, the further processability is improved.
- the produced highly filled paper web in particular the decor paper web, is provided for lamination to a substrate by lamination. It is connected under pressure and elevated temperature with the carrier material. As a result, end products such as kitchen worktops, laminate flooring, furniture and others can be produced.
- the turbulence channels viewed in the flow direction, comprise a first section and a second section and an end section with an outlet cross section. These sections have a hydraulic diameter that is calculated from the quadruple cross-sectional area divided by the circumference of the respective section of the turbulence channel. The ratio between the hydraulic diameter of the second section and the hydraulic diameter of the first section is greater than or equal to 1.25.
- the second section can, for example, pass over a separation-free diffuser into the end section. This contributes to the prevention or reduction of hydraulic instabilities in the suspension jet and thus to improve the flatness of the highly filled paper, especially the decor paper, and to reduce disturbances and defects in the lamination process.
- the second section includes the end section.
- the second section also forms the outlet cross-section with an outlet cross-sectional area.
- the turbulence channel thus has only two sections.
- the length of the second section is thus 4 to 10 times the root of the area of the outlet cross-section, the area in mm 2 and the length in mm.
- the length of the lamellae is the same or different.
- the length of the lamellae is between 0.3 and 1.2 times, in particular between 0.5 and 0.8 times the length of the nozzle.
- the nozzle has an inlet cross section assigned to a line and the ratio between the area of the inlet cross section and the sum of the outlet cross sections of the turbulence channels of a row is less than 1.75, wherein the inlet cross section of the nozzle is the cross section through which flow is possible. This avoids coarse hydraulic instabilities in the suspension jet.
- the area of the outlet cross-section is less than 600 mm 2 , preferably less than 350 mm 2 .
- the outlet cross section of the individual turbulence channels can be rectangular or square or hexagonal.
- the object is also achieved by the features of the device claim 8. It is a headbox for carrying out the method according to claim 1 for the production of highly filled papers, in particular decorative papers for application to a carrier material proposed.

- the head box may be followed by a forming area, a press area, a drying area, a take-up area and an impregnating device and / or a laminating device.
- the turbulence channels viewed in the flow direction, comprise a first section and a second section and an end section with an outlet cross section. These sections have a hydraulic diameter that is calculated from the quadruple cross-sectional area divided by the circumference of the respective section of the turbulence channel. The ratio between the hydraulic diameter of the second section and the hydraulic diameter of the first section is greater than or equal to 1.25.
- the sum of the lengths of the second section and the end section is 4 to 10 times the root of the exit surface, wherein the exit surface in the unit mm 2 and the length in the unit mm is indicated.
- the second section can, for example, pass over a separation-free diffuser into the end section. This contributes to the prevention or reduction of hydraulic instabilities in the suspension jet and thus to improve the flatness of the highly filled paper, especially the decor paper, and to reduce disturbances and defects in the lamination process.
- the second section includes the end section.
- the second section also forms the outlet cross-section with an outlet cross-sectional area.
- the turbulence channel thus has only two sections.
