Definitions

  • the invention relates to a device for the simultaneous application of at least one layer of liquid coating material to a surface of a good, in particular a belt, with a downwardly sloping sliding surface over which at least one layer of liquid coating material flows down before it is layered on the good outlet slots located in the sliding surface for the supply of coating material to the sliding surface, with edge strips for lateral guidance of the layers on the sliding surface and with a dispensing of the coating material arranged at the lower end of the sliding surface on a material moving past the flow direction of the coating material.
  • a device of the type mentioned above which makes it possible to coat a moving, band-shaped carrier material in such a way that discrete layers, ie mutually unmixed layers formed are shown in U.S. Patent 2,761,791.
  • the surface of the band-shaped carrier material to be coated is moved past a coating bead in which the coating materials of the individual layers are arranged discretely, so that a coating is applied to the carrier material, which coating is formed from a plurality of discrete, superimposed layers.
  • the coating materials are fed continuously to the coating bead by a suitable coating device, for example a sliding surface caster, which is arranged at a short distance from the surface of the carrier material, so that the coating bead can bridge the distance between the band-shaped carrier material and the lip of the coating device.
  • a suitable coating device for example a sliding surface caster, which is arranged at a short distance from the surface of the carrier material, so that the coating bead can bridge the distance between the band-shaped carrier material and the lip of the coating device.
  • the thickness of the layers that can be successfully deposited on the carrier material depends on the operating behavior of the coating bead and can be controlled by factors such as the running speed of the carrier material and physical properties of the coating materials.
  • a disadvantage of the above-mentioned multiple coating process is that it is normally necessary to make the lowermost layer, ie the layer that comes into contact with the band-shaped carrier material, from a coating material of low viscosity and to apply this lowermost layer with a high wet coating.
  • the bottom layer typically has a viscosity in the range of about 3 to 10 cps, and the specific wet coating is in the range of about 40 to 100 cm 'of coating material per m 2 of area of the substrate.
  • Such a high specific wet coating and such a low viscosity are used for the bottom layer because turbulence takes place in the coating bead.
  • the lowermost layer has a considerable thickness and is formed from a coating material of low viscosity, then this turbulence is confined entirely to the lowest layer, so that mutual mixing between the coating material of the lowermost layer and the coating material of the layer immediately above it is avoided itself at high coating speeds.
  • the term turbulence refers to a shearing and mixing process that does not necessarily lead to eddy formation. The exact properties of this turbulence depend on several factors, including the physical properties of the coating materials and the coating speed.
  • the coating speed depends on the settling and / or drying time, which can result in the coating having to be carried out at an unfavorably low operating speed in order to avoid the risk that the settling and / or drying capacity will be exceeded becomes.
  • the performance of those devices which serve to provide the coating materials must be increased if the coating materials have to be thinned in the interest of facilitating the coating process. This results in a remarkable increase in setup costs.
  • the invention has for its object to provide a device of the type mentioned, with which it is easily possible to provide sliding surface casters for the bead coating or the curtain coating process with thin auxiliary layers on the sliding surfaces.
  • the sliding surfaces between the outlet slots and / or the device for dispensing the coating material at the lower end of the sliding surface consist of a porous material with a defined pore size and are arranged above cavities and liquids are supplied to the cavities, which escape due to their static pressure or by capillary action through the porous material on the surface of the sliding surface and / or on the device for dispensing the coating material.
  • a web can be dried through the low-viscosity, highly viscous layers at considerably higher speeds, especially since the flow properties of the coating solutions from the sliding surface can also be improved by the auxiliary layers during coating.
  • the individual layers for example in the production of photographic materials, can be precisely matched to one another in their physical and phototechnical properties. This applies particularly to the bottom layer, which is crucial for adhesion to the surface of a good, for example a film or paper web.
  • a precisely defined amount of lubricant or wetting agent can be added shortly before contact with the web. Because, instead of the entire layer, only the boundary layer absorbs the wetting agent or lubricant, wetting or lubricant can be saved to a considerable extent.
  • the porous materials can be metallic, ceramic, glass or plastic sintered plates, which consist of a well wettable material with uniform solid surface tension and are selected so that a defined amount of liquid exits through the pores and capillary evenly over the surfaces of the sintered plates.
  • Sintered plates made of stainless steel alloys for example V4A (a material according to DIN 14404), have proven to be particularly advantageous.
  • the material is made from pre-selected metal powder under protective gas in a sintering furnace.
  • the metal particles have an amorphous structure and form multiple weld-like connections when sintered without a binder.
  • the sintered material is manufactured without pressure, which ensures high permeability. It can therefore be a material and a pore size of five to twenty microns and a thickness of 1.5 to 5 mm for the sliding surfaces and a profile material with a pore size of ten to 40 microns can be used:, from the profile material, the trailing edge for the Working surface is worked out.
  • the sintered material is available in all sizes and thicknesses and in many shapes and is easy to process.
  • the liquids supplied to the cavities under the sintered plates are lubricants and wetting agents or other liquids which are caused by a static pressure, emerge by means of pumps or by capillary action through the sintered plates on the sliding surface and form a thin auxiliary layer under the coating liquids.
  • non-ionic surface-active agents such as saponin (steroid type), alkylene oxide derivatives (such as polyethylene glycol, polyethylene glycol / polypropylene glycol condensates, polyethylene glycol or alkyl) can be used as lubricants or wetting agents for improving the sliding properties for photographic emulsions or other hydrophilic colloid layers -alkylaryl ethers, polyethylene glycol esters, polyethylene glycol sorbitanic acid, polyalkylene glycol alkyl amines or amides, polyethylene oxide adducts of silicones), glycidol derivatives (such as alkynisuccinic acid polyglycerides, alkylphenol polyglycerides), fatty acid esters of polyhydric alcohols, alkyl esters of sucrose, or the like or urethanes thereof, or the like; anionic surfactants containing an acid group such as a carboxyl group, a sulfo group, a phosphorus
  • surface-active agents for other purposes to the emulsions flowing down the sliding surfaces, for example antistatic agents for preventing electrostatic charges, agents for improving the emulsion dispersion, agents for preventing adhesion or agents for improving the photographic properties, such as hardening agents, in particular quick-curing agents , chemical couplers, stabilizers, UV absorbers, sensitizers and the like.
  • An advantageous embodiment of the device is characterized in that the sintered plates are arranged interchangeably and detachably above the cavities.
  • cleaning of the device is made easier and by exchanging the sintered plates it is possible, for example by selecting sintered plates with certain pore or capillary sizes, adapt the sliding surfaces to the various requirements of casting problems.
  • a normal adjustment is already possible within wide limits through the static pressure or the pump pressure with which the lubricants or wetting agents are pressed against the sintered plates.
  • a particularly advantageous embodiment of the device is characterized in that the sliding surface is wider in the area of the lower end and is provided on both sides with cavities for receiving liquids which reduce the surface tension of the coating liquids and which are covered with sintered plates.
  • the device is further characterized by the fact that it can be used both for coating webs using the bead coating method (cascade method), with a caster edge at the lower end of the sliding surface, which the web is guided past on a casting roller at a short distance, as also that it can be used in an equally advantageous manner for the coating of webs by the curtain casting process, with a beak-like extension of the sliding surface at the lower end of the sliding surface, through which the coating liquid flows and is applied as a free-falling curtain to a web moving beneath it .
  • cascade method bead coating method
  • the formation of the sliding surfaces from porous material is the same for both coating processes.
  • a foundry edge is arranged at the lower end of the sliding surface, which is also provided with a porous material and is wetted with a lubricant, so that the foundry edge is surrounded by an auxiliary layer.
  • the foundry edges differ only in their shape, with those for the bead coating process has a shape on which a bead forms with the help of a vacuum between the web and the caster edge, while the caster edge in the curtain casting process is advantageously beak-shaped, so-called beak sliding surface caster, whereby the layers are more easily detached from the caster edge and free-falling in this embodiment Curtain can be placed on a moving path below.
  • Fig. 1 shows a schematic representation of an embodiment of a sliding surface caster 1 for the bead coating process.
  • One or more coating liquids 5, 6 are supplied to the distribution pipes 2 by pumps and rise over the entire width of the Sliding surfaces 4 in outlet slots 3 to the sliding surface 4 and, due to the force of gravity, flow down the sliding surfaces 4, flow one above the other and reach the casting edge 12.
  • a material to be coated for example a material web 14 with a casting roller 15, is guided past the casting edge 12 at a short distance .
  • the layers 5, 6 form a bulge 13, from which the layers 5, 6 lie on the web 14 passed by.
  • the bulge can be controlled in the usual way by applying a vacuum.
  • the sliding surface 4 consists of a porous material such as sintered plates 7, which consist of a cemented carbide, ceramic, sintered glass or are made of plastic.
  • the sintered plates cover cavities 8 under the sliding surface 4, into which a wetting or lubricant is introduced by means of distributor pipes 9 from containers 10, 11 with static / pressure adjustable via the height of the containers or via metering pumps.
  • the wetting or lubricant penetrates the sintered plates 7 from the inside out and wets the sliding surface 4 with a thin auxiliary layer on which the layers 5 and 6 slide down the sliding surface 4.
  • the foundry edge 12 which is also made of porous material and is completely wetted with wetting or lubricant, so that the bottom layer 6 easily and evenly over the width of the foundry edge 12 and detaches with heavily wetted boundary layer on the web 14 creates and is liable to this.
  • the amount of wetting agent or lubricant can be easily changed by changing the height of the wetting agent container. 10, 11 can be set.
  • the sliding surfaces 4 rest positively on the cavities and seal them so that the wetting or lubricant can only escape after the sliding surface 4.
  • the sintered plates 7 can be removed.
  • Various sintered plates with different pore sizes and capillary sizes can also be provided for a casting device, which are installed as required. In general, however, no sintered plates with different pore sizes are required, since the thickness of the auxiliary layer of wetting agent or lubricant can be adjusted over a wide range solely by changing the static pressure.
  • FIG. 2 shows a longitudinal section through a device 1 according to the invention for the curtain coating process.
  • a device 1 for the curtain coating process.
  • one to twelve (or even more) individual layers can be brought out of the distributor pipes 2 through the outlet slots 3 onto the sliding surface 4. With gravity these layers flow down on the sliding surface 4, flow over one another and reach the beak 16 of the curtain.
  • the layers detach together and fall as a free-falling curtain 17 over a height of 5 to 20 cm Web 14 guided vertically beneath the beak, which can be deflected via a casting roller 15 in order to support the web 14 at the point of impact.
  • the representation of the device is purely schematic, the usual aids for a perfect casting, such as edge guides, air signs and other known devices, have not been shown.
  • the supply of the wetting or lubricant is carried out as described in Fig. 1 in an analogous manner. Only the lowermost cavity 3 is made larger in order to be able to take up more wetting and lubricating agents and also to provide the beak 16 with wetting or lubricating agents up to its lowest tip. As a result, the surface tension when the lowermost layer carrying the remaining layers is detached is considerably reduced and uniform detachment from the edge of the beak 16 is ensured. A crusting or a build-up of coating materials by drying is avoided.
  • edge beads are decisive for the drying time of a web after watering, since the web can only be wound up when. all parts, including the edge beads, are dry. Because of the marginal ridges alone, drying times and distances are required, which must be 20 to 40% longer than those required for the normal shift. The edge beads are also unusable and will be cut off on both sides in a later step.
  • edge beads it is known, among other things, to angle the edge strips 18 in the lower region of the sliding surface 4 outwards by an amount a, so that the sliding surface 4 has a width b + 2a just before the pouring edge 12.
  • the edge bead is reduced because the layers expand in the edge area and require coating material for this and thus reduce the layer thicknesses. This creates the risk that the thinned layers will tear when the device for the curtain casting method according to FIG. 2 is used, or that in the bead coating method according to FIG. 1 there will be faults in the pouring bead, which results in a streaky pouring in the edge area which is also not usable .
  • a considerable improvement is achieved if, under the enlarged areas a, cavities 19 are arranged which are covered with sintered plates 7 and which Cavities 19 from containers 20 via valves 21 and pipe connections 17 can be charged with a wetting agent or lubricant.
  • coating liquids supplied through the distributor pipes 2 rise in the outlet slots 3 to the sliding surface 4 and flow over one another and as a result of gravity down the sliding surface 4 in width b.
  • the thickening of the layers that forms on the edge strips 18 reach the auxiliary layer of lubricants or wetting agents that forms above the sintered plates 7 and, with simultaneous thinning, follow the sliding surface 4 that is widened outward by the amounts a. This results in only slight thinning of the adjacent layer and the edge thickening. equalize, so that the layers striking the web show almost no thickening at the edges and the drying time can be shortened considerably.
  • FIG. 3 The expanded edge strips 18 with sintered plates arranged underneath are shown in FIG. 3 as the sole improvement.
  • a sliding surface 4 with sintered plates 7 as described in FIGS. 1 and 2 can also be used in the device.
  • edge strips 18 even on the side facing the sliding surface 4 of the sliding surface caster 1 consist of a sintered plate 7 which are supplied with wetting agents and lubricants through the channels 22 in the edge strips 18 .
  • An auxiliary layer then also forms on the edges of the edge strips 18 covered with sintered plates 7, which reduces the surface tension of the layer edges and reduces the rising of the layers 5, 6 on the edge strips 18 and thus the edge bead on the web.
  • These special edge strips 18 can be used both in a normal sliding surface caster and in a sliding surface caster 1 of the type described in FIGS. 1 and 2.
