Definitions

  • the invention relates to a method for producing a material web, on at least one side of a support a plastic layer made of a mixture of plastic material and particle-like soluble particles is generated, wherein the soluble particles can be removed by such a solvent are resistant to which the plastic material and that thereafter the soluble particles are at least partially from the plastic layer with the formation of through-channels be detached.
  • a material web of the type mentioned above for use in a paper machine is described in EP-B-0 196 045.
  • she has as a carrier a liquid-permeable fabric on which a 1.3 to 5 mm thick layer of an elastomeric polymer resin is applied.
  • the plastic layer has through channels on that of the otherwise smooth and flat outside go through to the support and in the paper machine as drainage channels serve.
  • the through channels are manufactured in such a way that textile fibers are homogeneously dispersed in the polymer resin, before the mixture of textile fibers and polymer resin on the carrier is applied.
  • a nonwoven can be used first applied to the carrier and then the coating with be made of the polymer resin.
  • the textile fibers are removed after application of the Polymer resin by applying the solvent so that channels arise that the shape and the course of the detached Correspond to textile fibers.
  • Textile fibers instead of Textile fibers suggested particulate particles that are homogeneous be distributed in the polymer resin. As material for this Particles become inorganic salts or their hydrates or oxides suggested. They can be made using appropriate solvents in the same way as the textile fibers made of the polymer resin are removed and leave pore cavities.
  • the soluble components - are there are fibers or particle-like particles - in the polymer resin distribute evenly and this distribution when applying maintain the mix.
  • the mixture it comes from polymer resin and soluble components to segregation, so that it is not guaranteed that by the detachment of the particles through passageways arise. Out for this reason, no different distributions can be made produce the soluble components across the cross-section.
  • polymer resins tend to harden after curing to form a closed surface, which is the detachment of the soluble textile fibers contained in the polymer resin or Particles hindered.
  • the surface of the plastic layer to grind so that a connection to the soluble Fibers produced and also creates a smooth surface becomes.
  • a grinding process is very time consuming.
  • it must be in an appropriate excess Plastic material can be applied and during the grinding process dust accumulates, which is vacuumed and either disposed of or returned must be processed.
  • a smooth surface arises, which detaches the paper web from the paper machine belt with special needs. Namely, paper webs tend to stick to themselves vacuum smooth surfaces.
  • paper machine belts are used This type has a number of advantages over known felts attributed according to the batt-on-base principle, namely enlarged Resistance to permanent deformation and therefore longer Operating times and consequently lower set-up costs, improved abrasion resistance and higher structural strength, lower Affinity for contaminating substances as well as more uniform Pressure distribution and thus improved drainage.
  • WO 86/05219 describes a method for producing a Paper machine belt disclosed in which a polymer material, mixed with soluble particles, in plasticized Form on a barbed tape to form a plastic layer is applied. For curing this plastic layer and / or to remove the detachable particles the plastic layer is subjected to a post-treatment with heat become. Leave after peeling off the polymer tape the spines of the barbed conical through holes back.
  • the polymer material can also have a reinforcing structure provided in the form of fibers, threads or fabrics his.
  • WO 91/14558 proposes the through-channels by producing that on the not yet hardened Put on a shadow mask and then this is irradiated. This hardens due to this radiation Plastic material in the area of the holes of the mask. After removing the shadow mask, the not yet hardened is then Plastic material removed using compressed air. Also this process is complex and leaves relatively large free areas and therefore cannot be used universally become. In addition, waste to be disposed of or reprocessed also falls here Waste.
  • the material web initially consists exclusively of polymer particles is produced by exposure to heat at their contact points be connected to each other. If necessary can complete a reinforcement structure like a reinforcement be stored in the band thus formed. Here it can be a pure fiber product or a fabric.
  • the particles can also have different diameters have one increasing from one side to the other To create permeability.
  • a polymer coating is made using a peel film under the simultaneous exposure to heat and Pressure applied to a support, the polymer film due to the heat on the peel-off film Drops forming free spaces with the Consequence that the plastic layer applied to the carrier is porous. It is also difficult with this method Permeability of the plastic layer can be set reproducibly and adapt to the respective requirements. Also stand Foils in the width required here are not available and would also not be able to be produced with sufficient uniformity.
  • the invention has for its object a method for manufacturing to provide a material web of the type mentioned at the outset, with which a desired distribution of the soluble Can achieve particles within the plastic layer.
  • a another task is to design the process so that the soluble particles are easily removed from the Let out the plastic layer.
  • This object is achieved in that as Plastic material a plastic powder is provided that mixes with the soluble particles and applied to the carrier and that by heat and pressure treatment from the Mixture of plastic powder and soluble particles a plastic layer generated with the soluble particles contained therein is before the soluble particles at least partially be detached from the plastic layer.
  • the grain size of the particles of the plastic powder and also the the soluble particles and their mixing ratio can each can be set within wide limits as required so that a desired structure of the plastic layer results, in particular what about after the soluble particles have been extracted resulting cavities of the through channels.
  • the soluble particles should have an average diameter from 30 to 50 ⁇ m.
  • the average grain size of the plastic powder should be less than that of the soluble particles, expediently only half to a third of the soluble Particles are and in no case be more than 100 microns. In this way the soluble particles become a plurality or even a variety of particles of plastic powder practically encased, and there is a relatively tight package.
  • the volume ratio between plastic powder and soluble Particles should expediently be set so that that the soluble particles are not just in the cross-plane direction the plastic layer, but also in the plane of the plastic layer lie at least partially against each other, so that also in the Level of the plastic layer open pores and thus drainage volume provided and thus the water absorption capacity is improved.
  • the volume ratio between plastic powder and soluble Particles are expediently in the range between 1/4: 3/4 and 1/2: 1/2, preferably in the range 2/3: 1/3.
  • the plastic powder and the soluble particles can also applied in layers, with different layers Grain sizes, materials and mixing ratios can be provided to account for the respective requirements to wear. So the soluble particles can go to the carrier grow in layers or continuously. Alternatively or in combination can also the number of soluble particles increase from layer to layer towards the carrier. Both measures serve to increase the permeability to the wearer to let this be particularly so when using the web of material desirable in the forming and press area of a paper machine is.
  • Another advantage of this procedure is that by indenting the soluble particles where the soluble particles Particles are present on the outside near the surface, a connection to these is established. After detaching The solvent has access to the soluble particles soluble soluble initially enclosed in the plastic layer Particles and can therefore also completely dissolve them remove. The impressions then form the openings of the through channels. The procedure thus replaces the Grinding treatment according to EP-B-0 273 613.
  • the soluble particles in such a density are applied to the plastic layer, that at least the impressions remaining after removal partly with each other and with the through channels stay in contact. This design is particularly effective when used as a paper machine belt cheap for drainage out.
  • the soluble particles should preferably be at a temperature the plastic layer can be pressed into this the plastic layer compared to the condition at room temperature is softened. This can be done in that the soluble Particles following the creation of the plastic layer applied at an even higher temperature and pressed in.
  • the pressing can be done by a calender treatment become.
  • the soluble particles should be a medium one Have a diameter of 5 to 100 ⁇ m.
  • both should be made of the same material so that the removal can be done in one operation using the same solvent.
  • those substances should be selected which remain essentially dimensionally stable under the heat effect of the production of the plastic layer.
  • polymeric particles come into question which have a higher heat resistance than that of the plastic matrix in which the soluble particles are embedded. These conditions should expediently also apply to the soluble particles pressed into the outside of the plastic layer.
  • soluble particles or particles are not adversely affected by the heat treatment necessary for the formation of the plastic layer and are easy to pour and therefore scatterable.
  • Organic substances e.g. B. carbohydrates (sugar), or salts of organic acids, such as citric acid, ascirbic acid etc.
  • An additional antioxidant should be added to the plastic powder.
  • soluble particles of at least two substances are used, each one of the substances by a solvent is removable, against which the other substance (s) is or are stable.
  • This idea is basically that EP-A-0 303 798 and EP-A-0 320 559 in which the use of soluble fibers within a felt is suggested has been. It is understood that these soluble particles compared to the conditions of use for which the material web is intended is, must be constant, d. H. in case of use as Paper machine belt compared to those coming from the paper web Liquids or vapors. Alternatively, can be provided be that the soluble particles are only delayed and successive let out of the matrix.
  • a second plastic layer with through channels created in the same way as on one side becomes.
  • the number and / or size of the soluble particles should be considered facing away from the carrier in the second plastic layer increase, and it should be the number and / or size of soluble Particles in the areas of both plastic layers adjacent to the carrier be the same size. It is understood that others too Distributions are possible if this is for the intended Use is more appropriate.
