Definitions
- the present invention relates to a plastic molding, preferably a plastic pipe, in particular for the transport or storage of fluids, which comprises at least one layer containing zeolite particles, in which at least a portion of ion-exchangeable ions have been replaced by biofilm-inhibiting ions.
- plastics for the transport or storage of liquid and / or gaseous media.
- Such plastic pipes serve, for example, the transport of drinking water from drinking water reservoirs to the end user, but also the return of wastewater from the end user to wastewater disposal companies.
- Organisms may be plants such as algae, while microorganisms include, for example, bacteria and fungi.
- the corresponding deposits lead on the one hand to a reduced flow cross-section, and on the other hand to a negative influence on the quality of the transported drinking water. This can even lead to an epidemic risk if the biofilms formed contain pathogenic germs.
- the microorganisms of the biofilm cause biologically induced damage to the tube material during prolonged exposure. In this context, for example, the degradation of the plastic by mushrooms may be mentioned.
- zeolite particles with biofilm-inhibiting ions can inhibit or suppress the formation of a biofilm.
- a disadvantage of this method for preventing the formation of a biofilm is the fact that present in the zeolite particles biofilm-inhibiting ions dissolve relatively quickly from these and migrate to the corresponding molding surface, so that the biofilm-inhibiting ions are rapidly consumed and after a short time biofilm-inhibiting effect is lost.
- the invention is therefore an object of the invention to provide a plastic molding, preferably a plastic pipe, which effectively counteracts deposition of microorganisms or pollutants, and generally the structure of a biofilm, for a long period of time and is easy and inexpensive to manufacture.
- the plastic molded part according to the invention is characterized in that the layer further contains nanofil size biofilm-inhibiting particles in addition to the zeolite particles. It has been found that the combination of zeolite particles with biofilm-inhibiting ions and biofilm-inhibiting particles in nanometer size, a very long-lasting biofilmhemmende effect can be achieved. Initially, the use of the plastic tube initially leads to migration of the biofilm-inhibiting ions, which dissolve out of the zeolite particles. Thus, practically from the very beginning, rapid release of the ions and their correspondingly rapid migration to the surface of the plastic pipe result in highly effective protection against the attachment of organisms or microorganisms.
- the ions of the zeolite particles and the biofilm-inhibiting particles in nanometer size complement each other ideally, because as the one, ie the ions of the zeolite particles are used up, the ions of the biofilm-inhibiting particles come to fruition, the effect of which lasts for a very long time.
- biofilm-inhibiting ions may comprise copper ions and / or zinc ions and / or silver ions
- biofilm-inhibiting particles may comprise copper and / or zinc and / or silver.
- the materials copper, zinc and silver or their ions have particularly favorable (antimicrobial) properties in terms of avoiding the formation of a biofilm, they are preferably selected.
- the biofilm-inhibiting particles may have a largest diameter between 1 and 100 nm, preferably 10 and 50 nm. It has been found that the particles have a particularly advantageous effect in this size range. Furthermore, it may be advantageous if the concentration of zeolite particles and biofilm-inhibiting particles in the sum of 0.01 to 15 weight percent, preferably 0.1 to 5 weight percent, based on the layer of the plastic tube containing them is. The amount of zeolite particles and biofilm-inhibiting particles is advantageously chosen in a ratio of 20:80 to 80:20.
- the layer may comprise a matrix material in which the zeolite particles and the biofilm-inhibiting particles are embedded. As a result, the particles are held securely and firmly and fixed in the plastic tube.
- the matrix material comprises and preferably consists of a thermoplastic polymer such as polyethylene, crosslinked polyethylene (PE-X), polypropylene, polybutene or polyvinyl chloride and copolymers thereof. These materials have favorable mechanical and physical or chemical properties and are also relatively inexpensive with ease of processing.
- a thermoplastic polymer such as polyethylene, crosslinked polyethylene (PE-X), polypropylene, polybutene or polyvinyl chloride and copolymers thereof.
- the zeolite particles and / or the biofilm-inhibiting particles are distributed uniformly in the matrix material, or that the concentration of the zeolite particles and / or the biofilm-inhibiting particles in nanometer size starting from the outer surface of the layer facing away from the fluid in the direction of the Fluid-facing inner surface of the layer continuously increases or decreases.
- the distribution of the zeolite particles and / or the biofilm-inhibiting particles can be varied or adapted. For example, if there is a desire to protect both the inside surface (i.e., the surface in contact with the fluid) and the outside surface of a pipe from biofilm deposition, then a homogeneous distribution is desirable.
- the increased concentration of the zeolite particles or of the biofilm-inhibiting particles in the vicinity of the inner surface offers advantages.
- the concentration of zeolite particles and / or biofilm inhibiting particles may be advantageous for the concentration of zeolite particles and / or biofilm inhibiting particles to increase from the center of the layer toward the inner surface and outer surface.
- the concentration of zeolite particles with biofilm-inhibiting ions and biofilm-inhibiting particles in nanometer size can have a steady gradient or a non-continuous gradient, ie a jump in the layer.
- the concentration of zeolite particles with biofilm-inhibiting ions and biofilm-inhibiting particles in nanometer size can be selected such that a first partial layer is advantageously present in the layer, the zeolite particles with biofilm-inhibiting ions and a second partial layer having biofilm-inhibiting nanoscale particles.
- An unsteady gradient, which has a jump can advantageously be effective if the migration of the ions is to occur with a delay.
- the plastic tube is two- or multi-layered, wherein the innermost, the fluid-facing layer is formed by the described in the above-described advantageous embodiments layer, and the adjoining outer layer or the adjoining outer layers comprising or having a polymeric material.
- the two- or multi-layered construction makes it possible to realize a more robust and more mechanically stressable pipe, wherein the respective layers can be designed in the sense of the respective intended function.
- the inner layer is designed so that it prevents the attachment of microorganisms or pollutants
- the outer layer adjoining outer layer for example, is designed to ensure a high mechanical stability of the tube.
- Layers comprising a thermoplastic polymer such as polyethylene, crosslinked polyethylene (PE-X), polypropylene, polybutene or polyvinyl chloride and copolymers thereof and preferably consists of this or consist of.
- a thermoplastic polymer such as polyethylene, crosslinked polyethylene (PE-X), polypropylene, polybutene or polyvinyl chloride and copolymers thereof and preferably consists of this or consist of.
- PE-X crosslinked polyethylene
- polypropylene polypropylene
- polybutene polyvinyl chloride and copolymers thereof
- the tube is two or more layers and is made by a co-extrusion process. This is a particularly effective and economical process for producing multilayer pipes.
- the layer of zeolite particles with biofilm-inhibiting ions and biofilm-inhibiting nanometer-sized particles is prepared in a process in which a fluid is passed into the tube lumen and precipitates on the inner surface to form the layer.
- the fluid may be a liquid in the form of, for example, a lacquer which contains the zeolite particles and biofilm-inhibiting particles.
- the layer formation can be carried out from a gas phase.
- Such a technique for producing coatings is very effective and economically usable for producing multilayer pipes.
- the tube is two- or multi-layered and the layer thickness of the innermost, the fluid-facing layer is between 1 and 10% of the wall thickness of the tube.
- the desired anti-tarnishing function of the innermost layer is ensured.
- this results in a relatively low material consumption for the innermost layer, which has a cost-reducing effect on the production of the tube.
- the mechanical material behavior of the entire tube is only insignificantly influenced by it.
- the layer thickness of the innermost layer facing the fluid is between 1 and 10% of the wall thickness of the tube.
- FIG. 1 is a sectional view of a single-layer pipe according to the invention
- Fig. 2 sectional view of a two-layer pipe according to the invention.
- the not-to-scale representation according to FIG. 1 shows a section through a single-layered tube 1 according to the invention, the tube 1 having a layer 2 with an outer surface 5 and an inner surface 6.
- the layer 2 contains as the matrix material polyethylene, in which the zeolite particles 3 and the biofilm-inhibiting particles 4 are embedded.
- the zeolite particles 3 as biofilm-inhibiting ions silver ions, while the biofilmhemmenden particles 4 are made of silver and have a maximum diameter of 10 nm.
- the concentration of the zeolite particles and the biofilm-inhibiting particles is greatest in the area of the inner surface 6 and steadily decreases in the direction of the outer surface 5.
- the inner layer 2 here corresponds to that shown in FIG. 1 and has the same structure.
- the outer layer 7 is made of PP.
- the inner layer has a thickness of about 1 mm, while the wall thickness of the tube is about 15 mm.
