Definitions

  • the present invention refers to a procedure for the manufacture of a multi-layer pulp product, in particular a product selected from between paper and cardboard and which presents the essential characteristic of incorporating a filler between layers.
  • the fillers are of vital importance since by means of them a saving can be achieved in the amount of virgin or recycled fibre that is used.
  • the object of adding fillers during manufacture is also to improve or acquire certain properties that are desired in the end product: improvement in optical properties such as whiteness, opacity, brightness and colour; improvement in properties relating to permeability to fluids, such as penetration of water or ink, penetration of oil and porosity or resistance to the passage of air.
  • the addition of fillers to the paper also permits the speed of the machine to be increased, which improves its production.
  • International application WO-9600816 describes a method and a device for applying a film of a coating material on a network or tissue of fibres in a paper or cardboard machine.
  • the coating material is applied on the surface of the mesh of the pulp product by means of a spraying system at low pressure and high flow.
  • the system is equipped with a series of spray guns adjacent to the mesh of the pulp product. Nevertheless, this procedure is solely intended for the manufacture of mono-layer paper.
  • the mono-layer paper coating thus described has the drawback that it is complicated to achieve a correct distribution of the filler over the entire section of the paper since the penetration of the filler within the fibre mesh will vary radically depending on the point of application.
  • European patent EP-0 373 276-A1 describes a procedure and device for the continual spraying of adjuvants on a permeable fibre mesh arranged on a belt which is displaced.
  • the system permits spraying of the adjuvants in different states of humidity of the sheet undergoing formation by means of one or various spraying ramps.
  • Each of them is supported by a movable support frame transversely arranged in relation to the direction of displacement of the belt.
  • This ramp is constituted by two ducts provided with nozzles for the transport of the adjuvants, with starch being the product that is sprayed and which penetrates throughout the entire thickness of the sheet.
  • the present invention refers to a procedure for the manufacture of a multi-layer pulp product. Said procedure essentially consists of applying a filler between at least two layers of fibre material in motion prior to the final joining of them together.
  • the present invention refers to a procedure for the manufacture of a multi-layer pulp product, characterised in that it consists of:
  • the position of the one or more application means with respect to the layer formation section of fibre material can be variable.
  • the fillers can be proportioned by the application means on one or another layer.
  • the introduction of filler is done at a distance of between 1 and 70 cm above the moving fibre mesh and preferably between 5 and 40 cm.
  • the fillers used in the procedure of the present invention are applied by one or several means which are transversely located on the moving fibre mesh, with those application means being arranged in one or several series at different distances from the entrance box for the pulp product manufacturing machine.
  • the means of filler application can also be arranged with an angle of inclination with respect to the plane of the moving fibre mesh of between 0 and 90 degrees, this angle preferably being 25 degrees.
  • the final configuration of the application system essentially depends on the speed and configuration of the pulp product manufacturing machine.
  • the application means of the filler are located in a transverse direction with respect to the direction of displacement of the moving belt.
  • the application of filler can be done by various application means, being able to be introduced in a single application or in successive layers of filler.
  • the means of filler application preferably consist of nozzles, the filler being applied by spraying of a suspension of the filler between layers of pulp material (the moving fibre mesh is displaced at a speed between 50 and 2000 metres a minute).
  • nozzles permits the introduction of filler according to a shape selected from between jets of conical shape and plane jets with variable angles of opening, preferably 60°.
  • the spraying can be done by means of a system that includes nozzles and a return, which provides effective control of the flow or stream in the nozzles.
  • the flow in the nozzles can be adjusted by control means and the said return.
  • the control means are preferably selected from between a pressure regulator, a flow regulator and a pump fitted with a frequency shifter.
  • the filler is introduced with a transference efficiency of greater than 70%, preferably between 90% and 100%.
  • the filler can penetrate into the interior of the moving fibre mesh with a depth that is determined by the distance of the application means of the filler with respect to the entrance box.
  • the filler is preferably sprayed at the end of the formation of the sheet at a distance from the entrance box that guarantees little penetration (in order to achieve the best coating of the inner layers).
  • the manufacturing machine for the product is preferably a paper or cardboard machine, and the multi-layer pulp product is paper or cardboard.
  • the procedure of the present invention can be carried out in any kind of paper or cardboard machine, so said machine can be a Fourdrinier type of machine, a cylindrical machine or a machine which is a combination of both.
  • the filler is preferably of inorganic origin, though it can include organic components.
  • the calcium sulphate is preferably dispersed in water (by means of vigorous stirring) in proportions of up to 60% by weight in relation to the total mass of the suspension.
  • the granulometry of the filler is also an important factor for the procedure of the invention.
  • the fine granulometry, coating power and high refractive index of calcium sulphate improve the opacifying capacity of the white layer.
  • the calcium sulphate used in the invention has a mean granulometry of between 0.5 and 50 ⁇ m.
  • the filler preferably has a particle size lying between 0.5 and 10 ⁇ m.
  • the filler can include a dispersant in a proportion between 0.01% and 1% of the weight of dry filler.
  • the filler is applied as an aqueous suspension, the quantities of water and filler being controlled preferably by weighing. Also, said filler is applied by generally controlling the stream by means of a flow regulator and/or by means of a pressure controller.
  • the rheological properties of calcium sulphate enable a wide range of dry extracts to be worked with, and the optimum quantity of filler between layers can thus be determined for each type of quality to be manufactured.
  • the filler is applied as an aqueous suspension consisting of between 99% and 40% of water. It preferably consists of between 90% and 70% of water.
  • the quantity of filler deposited on the fibre mesh lies between 0.5 g/m 2 and 50 g/m 2 , and very preferably between 5 g/m 2 and 15 g/m 2 .
  • the filler can optionally include one or more additives.
  • it can include various types of starches or mixtures of them.
  • the fibrous material constituting the multi-layer pulp product produced by the procedure of the present invention can be constituted by a paste selected from among virgin paste, recycled paste, paste that has been de-inked or not, all kinds of paste whitened or not, and mixtures of the above.
  • the present invention has as an additional object a paper or cardboard product produced according to the described procedure.
  • a mesh of cellulose fibres coming from recycled white paper is provided at a distance of 40 cm (h in figure 3) above the surface of the fibre mesh , having 14 nozzles like those shown in figure 2.
  • the angle of inclination ⁇ - as shown in figure 3 - of the nozzles with respect to the moving fibre mesh is 25°.
  • a 25% aqueous suspension is prepared of anhydrous calcium sulphate (coming from the dehydration of calcium sulphate dihydrate) with an average particle size of 3 ⁇ m.
  • the quantities of water and filler are controlled by weighing.
  • 17 g/m 2 of anhydrous calcium sulphate are proportioned on the surface of the moving paper (10% by weight on the white layer production).
  • the flow of filler is controlled by means of an automatic flow regulator, the spraying point being located at the end part of the formation table and after the water line. At the end of the formation table the joining of the white layer with the grey support takes place.
