Definitions

  • the invention relates to a method for producing a coated, multi-layer fibrous web, in particular packaging paper or board web, in which first a stream is produced, which successively at least one headbox, at least one wire section to form a multilayer fibrous web, a press section, a dryer section with dryer groups and then fed to a reel.
  • the document WO2006 / 024695A1 discloses a process unit with metal strip for smoothing paper webs.
  • the multilayer coating of paper or cardboard is the subject of the document EP1249533A1 ,
  • Cardboard and packaging papers are usually dried in their production in the paper machines with drying cylinders of a single-row and / or double-row dryer section.
  • optional suction elements especially for web stabilization available.
  • a disadvantage is the high space requirement for such dryer sections and also to view the limited drying capacity. Especially with regard to the required, ever-increasing machine speeds, the drying zones must be formed longer based on the total machine length.
  • the smoothness of the paperboard or packaging paper to be produced is usually produced in the production of paperboard using conventional calenders, such as hard-nip calenders with high maximum pressures and short residence times of the fibrous web in the nip.
  • conventional calenders such as hard-nip calenders with high maximum pressures and short residence times of the fibrous web in the nip.
  • SoftNip calenders soft roll covers are used to increase the residence time in the nip. This is disadvantageous, the slight increase in smoothness and the volume loss.
  • Other conventional smoothing methods, such as nip calendering or shoe straightening, use soft covers of the unheated roll.
  • the disadvantage here is also a slight increase in smoothness with simultaneous loss of volume.
  • the fibrous web or packaging paper or board web is also painted with a pigment coating. This achieves whiteness, smoothness, gloss and opacity of the web. Also, the printability of the web material is thereby increased, whereby it can serve as an information and advertising medium.
  • the printing is done in addition to digital printing, especially in the form of offset printing and gravure printing.
  • the fibrous web is painted on the cover side at least once.
  • the reverse side may remain uncoated, or will also be painted at least once.
  • coating amounts per side of up to 80g / m 2 are applied.
  • the application has hitherto been carried out with conventional coating units, such as film presses, coaters with roller application (LDTA applicators with long exposure time of the coating medium), coater with free-jet nozzles, or with commissioned work with a short residence time of the medium on the web (so-called Short Dwell Time Applicators or SDTA ).
  • the disadvantage is that only a limited application capacity and thus poor coverage and opacity of the fibrous web or packaging paper and board web can be achieved with these mentioned conventional order types.
  • the multi-ply fibrous web is pre-smoothed with a belt calender within or after a post-dryer section and then the top layer of the fibrous web is coated with a white pigmented coating layer by means of a curtain applicator and then dried and that in the press section (II ) At least a smooth roller is used, at least on the top layer acts.
  • the band used in the pre-smoothing of the fibrous web consists of more than 70% of plastic. There is a temperature of more than 80 ° C. at the strip surface in contact with the fibrous web.
  • Another advantage is that due to the white pigment-containing curtain coat, which is indeed very uniform and well-covering, only a low basis weight of the white and expensive fiber layer (top layer) is needed. This saves expensive raw materials without the lower fiber layers showing through and without the print quality deteriorating.
  • the method according to the invention offers the possibility of producing the fibrous web in at least two layers, preferably at least three layers, namely backsheet, middle layer, top layer, depending on the desired application.
  • white or bleached and / or deinked and / or wood-free fibers are provided, which are expensive. It is therefore all the more advantageous to be able to save these substances to a large extent because the described white coating layer is applied to the cover layer with the aid of a curtain coating. In certain cases (eg with white multiple lines) even the white cover layer can be completely replaced with the white line layer.
  • a curtain coater applies the application medium in a ratio of 1: 1, ie without excess to the moving fibrous web in its production process. On the web so only the amount of coating material or pigment-containing application medium is applied, which should also remain there. This saves the doctoring and the corresponding squeegee devices.
  • the at least one coating layer can be applied with a single- or multi-layered curtain applicator in the form of a slot die or a so-called slide die.
  • a condensation press drying is provided within the pre-drying section. This could also be done after the drainage in the press section and / or in a post-dryer section. This offers the advantage of an increased evaporation rate of greater than 40 kg / m 2 h and the smoothing of the fibrous web.
  • This type of drying with which conventional drying cylinders can be partially saved, should take place in a range in which the web has a solids content of more than 50% to about 90%, preferably more than 55%. At least such drying should therefore, as stated, preferably be carried out within the pre-drying section, and it is also conceivable to provide this also in the after-dryer section.
  • the mentioned high evaporation rate and smoothness is due to the fact that the fibrous web is guided with its one side via a preferably steam-heated cylinder and with its other side on a sieve and an overlying impermeable fabric.
  • a contact pressure with respect to the cylinder is exerted in this section with a, a part of the outer circumference of the cylinder overlapping the pressure hood.
  • a particular advantage is to be considered an improved heat transfer from the steam room of the drying cylinder to the fibrous web.
  • the paper strength and the surface properties are increased despite the possible savings of raw fibers. Also the order of strength can be reduced, in some cases even completely saved.
  • the production method according to the invention can be formed even more advantageously by feeding a fines into the headbox at the beginning of the production process for the formation of the cover layer of the multi-ply fibrous web. This achieves a very smooth cover layer, which forms a particularly good basis for later coating layer and which achieves a very uniform coverage of the fibrous web.
  • the head box can be designed as a perforated roller headbox or as a hydraulic headbox.
  • at least one headbox is equipped with dilution water control.
  • the central layer is equipped with a dilution water control with the advantage that the basis weight cross profile of the entire board web can be influenced by the position with the largest proportion of the total weight (center layer) the strongest. It is also conceivable a multi-layer casserole that is fed with different streams.
  • wire section all known form combinations can be used. Preference is given to the use of wire mesh, but also combinations of wire mesh and hybrid formers, such as the marketed by the company of the Applicant Duo D or Duo DK as combinations of at least one Gapformern and at least one wire screen use. It is advantageous if the said former is equipped with a Sieb thoroughlyel coupled, for example, with the marketed by the company of the Applicant Duo Shake. In the case of multi-layer concepts, this should preferably be provided for the layer with the highest layer basis weight, such as the middle ply.
  • a tandem NipcoFlex press (TNFP) with offset press which is quadruple felted and / or a press unit, consisting for example of a suction press roll in the first nip, a NipcoFlex press in the second nip and find an offset press in the third nip use.
  • the press concepts can be designed with closed or open web guide.
  • the stiffening, ie the support frames for the presses can be performed as so-called cantilevers. It is also possible to use seamed or even seamless felts in the press section. Dry contents of up to 57% can be achieved with the mentioned press concepts.
  • At least one smooth roller is used in the press section, which acts at least on the cover layer.
  • This can be done with the help of a known tandem press with three felts and a smooth roller, which is usually arranged below or with a so-called offset press, in which a nip is performed without any clothing.
  • This measure also contributes to a smoother cover layer, which in turn can be coated more uniformly.
  • the web is subjected to a condensation press smoothing after the predrying and before a subsequent coating with the at least one white coat layer.
  • This smoothing process leads to even higher smoothness values.
  • the condensation press smoothing works in a similar way to the condensation press drying, whereby the fibrous web is passed over a heated cylinder and brought into direct contact with a metal belt running over the cylinder, above which a pressure hood is located. A sieve or a clothing is hereby not available.
  • the cylinder (drying cylinder or Yankee cylinder) is preferably heated in each case with steam, wherein the cylinder surface reaches a temperature between 60 and 250 ° C, preferably 130 to 190 "C.
  • the method according to the invention can be further expedient if, following the curtain coating, the same side of the web is coated a second time with a conventional coating unit, such as a directly applied blade coater, then the other side also coated with a conventional coater and then dried with dryers becomes.
  • a conventional coating unit such as a directly applied blade coater
