Definitions

  • the invention relates to a device for coating color preparation with at least a mixing stage, which is composed of several components Coating color for an applicator device provides. Furthermore, the concerns Invention a method for the continuous production of coating color, which consists of consists of several components as well as a method for the production of coated paper.
  • Coated pigment coating colors contain dispersed in water, mostly inorganic pigments.
  • the paint is added to the binder to the Reliable and durable pigments on the paper réellezubri.
  • As another Ingredient include the coating colors thickener and various adjuvants as additives, around the required for the respective coating process chemical and adjust physical properties.
  • coating colors and their processing from the document WO 02/066739 A1 known. Also, from the document is a method for manufacturing of coated paper or board, in which a coating color with a so-called curtain coater in a free-falling curtain on a running Paper or board web is applied. Before the order is finished Coating color mixed over several mixing stages from their components. There when applying the coating color it must not contain air or other gases Degassed in an intermediate process step.
  • the invention is based on the object, the color preparation by a suitable To make the coordination of individual process flows more flexible and thereby to Improve overall process sequence in terms of cost-effectiveness and quality.
  • This object is achieved by a device for coating color preparation Claim 1 and a method for the production of coating color according to claim 11 and by a method for producing coated paper or cardboard Claim 16 solved.
  • a measuring device between the / the Mixing stages and the applicator device is provided by means of which physical properties of the coating color, in particular their viscosity, their Density, their air content or their water retention capacity, permanent can be measured, wherein a control device is provided which the Admixture of individual components of the coating color on the basis of the measured values of the Measuring device controls.
  • the invention proposes by measurements (which can be continuous or in Intervals take place) of the physical properties and / or optical Properties of the prepared coating color on variations of the properties of the initial products or production-related variations by a Feedback to the mixing of the components to respond.
  • This will be a flexible manufacturing process, for example, to fluctuations of individual batches or changes in ambient conditions can react without interrupting the manufacturing process and a Recalibration would be necessary.
  • the viscosity of the color It depends on the viscosity of the color and the interpretation of Mixing device achieved a complete homogenization of the coating color, wherein due to a small amount of stock in the mixing system, the coating color losses kept low and a quick color change is possible.
  • the color goes through the treatment device and passes without stocking directly into the Machine container of the coating device.
  • the controller provides for the necessary coordination of the individual processes with each other to increase the color flow coordinate, and ensure an economically advantageous, high System integration and production performance.
  • the inventive device for Color preparation requires only a small stock of coating color or their Components.
  • the Control device the admixture of the individual components of the coating color by adjustable valves, in particular throttle shut-off controls. hereby becomes the separate admixture of different components and their dosage the particular chemicals and conditions as well as the parameter of the final product customized.
  • the applicator is a curtain coater or a blade coater.
  • An advantageous embodiment of the invention provides that after the first Mixing a degassing device is provided. Following is the Entgasungsvoriques advantageously a vacuum fan, the always in certain amount of air present in the coating color.
  • a second Degassing device may be arranged subsequent to the first.
  • At least one further continuous mixing unit according to Degassing device for admixing further color components whose Zumischmengen are controlled in particular by the valves are arranged.
  • Admixture of individual components provided a static mixer, which In particular, no free air surface for the application medium offers.
  • a static mixer has the advantage that it is too strong a shear of the coating color avoids, with a possible unwanted air intake largely is prevented.
  • a mixing turbine optionally arranged with a downstream or sibling cooling device.
  • At least one filter preferably at the output end, incorporated into the device. hereby be at least immediately before applying the paint in her Impurities, for example particles and deposits of the coating color, away.
  • the device for coating color preparation is a Curtain coater arranged, optionally with a pulsation damper.
  • Pulsation damper reduces the pressure surges in the mixing system and ensures one even color flow in the coater.
  • a preferred embodiment of the method provides that the aqueous Dispersion of paint and / or pigments before the addition of surfactants and Thickening is subjected to degassing.
  • An advantageous embodiment of the invention provides that using at least one continuous mixing unit as second mixing stage thickener and Other additives are mixed under exclusion of air of the pigment dispersion.
  • the invention provides that for the production of coated paper or cardboard, an applicator is used which recovers a coating color
  • an applicator is used which recovers a coating color
  • Fig. 1 shows schematically a device according to the invention for Coating color preparation 1.
  • a first mixing stage 2 are over Feed lines pigments 22, water 23 and binder 24 and as further Components thickener 42 and other additives 43 added.
  • the thickeners 42 and the other additives 43 are controlled as well as surfactants 45 added.
  • the control takes place via controllable valves 48a and 48b be actuated by the controller 47.
  • the control device 47 opens or closes the valves 48a and 48b thereby according to the measured values by the continuous measuring devices 46a, 46b and 46c are obtained, the between the mixing stages and the applicator 91 are provided.
  • the Measuring devices record the physical properties of the coating color. In the example, their viscosity, their density, their air content and their Water retention. It is equally possible only one of the To provide measuring devices 46a, 46b and 46c, one or all of the measures the aforementioned properties.
  • the components are mixed.
  • the dispersion can use an additional mixing turbine go through a cooling device to homogenize the color and the through to reduce the mixing temperature increasing temperature.
  • the dispersion is fed by means of a pump 8 to a degassing device 3, in which it is sprayed at low pressure.
  • a degassing device 3 in which it is sprayed at low pressure.
  • a second Downstream of the degassing device In the figure 1 is therefore with dashed line indicated that on a first degassing device 3a, a second Deaeration device 3b can follow.
  • Fig. 2 shows a schematic representation of an apparatus for Coating color preparation with a coater 9, each with a mixing stage 2 and 4 before and after the degassing device 3.
  • the first mixing stage 2 is under Using a continuous mixing unit 21 an aqueous pigment dispersion made with binder and other additives. Subsequently, the Dispersion subjected to degassing in the degassing device 3.
  • a second mixing stage 4 is then thickener 42, 43 further additives Added surfactants 45 and again via filter 5 and a pulsation damper 6 fed to a coater 9.
  • the sub-mixture of surfactants and others attached substances takes place through a static mixer 44.
  • FIG. 3 shows a schematic representation of a further modification of Apparatus for coating paint preparation analogous to FIGS. 1 and 2 with a coater, in which an intermediate container 7 immediately after the continuous Mixing unit 21 is arranged and after the degassing device 3, a second Mixing stage 4 according to FIG. 2 follows.
  • Fig. 4 shows a schematic representation of a further modified Inventive device for coating color preparation with a coater with each of a continuous mixing stage 21 and 41 with additional mixing turbine 25th before and static mixer 44 after the degassing 3. This is a causes particularly homogeneous mixing of the color.
