Definitions

  • the invention relates to a process for the continuous production of plates and / or molded bodies formed therefrom from fiber-reinforced hydraulically setting compositions.
  • the object of the invention is to provide a method of the type mentioned in which flawlessly fiber-reinforced, uniformly thick plates with a targeted amount of fibers, fiber distribution and / or fiber orientation and molded bodies formed therefrom can be produced with uniformly smooth and optionally tempered surfaces.
  • the hydraulically setting compound is applied in a thickness that is uniform over the working width and the fiber reinforcement can be installed in a targeted manner. It is also possible to work with a mass that does not contain excess water and therefore does not have to be dewatered in a special process step.
  • the targeted fiber distribution and orientation can be easily controlled and monitored very easily, so that a largely uniformity of the plate produced is guaranteed.
  • a base By using a base, a clean, smooth, but if desired also colored and / or structured or profiled plate surface is formed.
  • a particular advantage of the method is that by folding the edge parts of the base around the raw plate edges of the not yet hardened mass, a straight lateral limitation of the plate and a rounding off already during the production process their edges. In this way, a further trimming process, be it in the fresh or hardened state of the plate, can be omitted.
  • the width of the plate can be adjusted from the outset within narrow tolerances and a subsequent straightening of the plate, which is always associated with material losses, is not necessary.
  • the width is adjusted by adjustable but fixed with respect to the moving belt guide elements, which are arranged above the belt at the desired distance from each other.
  • the underlay lying on the belt and moved with it serves both as a separating layer and for shaping the side edges of the plate. It can consist of different materials, for example a plastic film, a glass fleece or plastic-coated paper.
  • a variety of surface design of the plate in terms of color and structure is already possible through the base.
  • the underlay can be provided as formwork and can be removed as perfect and residue-free without any damage to the panel surface. In this way, the surface of the board becomes completely even and smooth and has no rough spots or cracks.
  • the underlay also provides protection for the finished panel, both when stacking and when being transported. Finally, the use of such a base saves the costly post-treatment required in conventional processes, since a base remaining on the plate represents an excellent post-treatment.
  • a mass-absorbing base is placed on a belt designed for continuous movement, to which guide elements are assigned according to the desired width of a plate to be produced.
  • This pad is preferably wider than the predetermined and defined by the distance of the guide members width of the plate to be produced, so that the edge strips at the L ijkssei- th of the base sufficiently high are or can be placed over the tops of the guide members.
  • a hydraulically setting mass is applied to the pad in a uniform thickness and in the width determined by the spacing of the guide elements. This can be done, for example, by extruding the mass through a mouthpiece whose opening corresponds to the width of the plate to be produced.
  • a cutting device is arranged above the transport path of the mass, which continuously ejects chips of the desired length into a chute, from which the chips are then broken down and oriented towards the surface of the Mass to be scattered. Since the mass is continuously moved under the pellet rain, the fiber chips coming from the chute are controllably distributed evenly on the surface of the mass.
  • the fiber chips are then pressed or built into their surface with the aid of a tool that acts on the entire width of the surface of the moving mass.
  • the installation depth can be regulated by adjusting the tool and the fiber distribution in the cross-section of the panel can be selected depending on the requirements.
  • the fiber chips are wetted and the mass is compacted.
  • a resilient tool is expediently used.
  • the process of fiber installation can be repeated several times in the same or in successive layers of the mass applied to the base.
  • continuous fibers can also be placed and / or drawn into the mass of the slab to be produced.
  • the continuous fibers can be impregnated in a manner known per se.
  • the underlay is wider than the plate to be formed and the parts of the underlay projecting above the plate on both sides are drawn up and cover the edges of the plate, the outer sides of these parts of the underlay slide on the guide elements. This prevents the mass from rubbing and adhering to the side of the guide elements. By placing the protruding parts of the underlay around the side edges of the raw panel, these are rounded off neatly.
  • Cement can be sprinkled on the exposed top of the finished raw board and / or a covering, for example a nonwoven that remains attached to the board or a removable film, can be applied.
  • the method according to the invention allows the outer surface of the finished panel to be treated, for example colored, profiled and / or tempered in some other way, even during the manufacturing process.
  • This can be done by applying a layer of paint, a profiled tape or another material suitable for tempering to the exposed side of the base.
  • the layer of paint or another material is absorbed by the moist, hydraulically setting compound extruded onto the base, or the profiling of a profiled strip is pressed into the compound, so that the finished plate is colored, profiled and / or otherwise coated Preserves surface. This means that the plate surface can be reworked later . superfluous.
  • the method according to the invention makes it possible to work with a fiber-reinforced, hydraulically setting mass without excess water.
  • the raw plate is either left as a flat plate until it has finally hardened or is brought into a corresponding shaping device for deformation.
  • additives can be added to optimize the consistency and the cohesiveness.
  • the mass can also be modified by vibration for the installation of the fibers and the molding process.
  • the fibers can be disrupted by suitable shaping of the chute and / or by means of installations in the chute, the latter being able to be moved in a stationary or driven manner.
  • the desired orientation of the fibers is achieved in particular by dimensioning the chute opening to match the fiber length.
  • the resilient tool used for the gentle installation of the fibers in the mass can engage with a plurality of parallel cutting edges in the mass and apply the desired spring force through the inherent elasticity of a material used for its production.
