Definitions

  • the invention relates to an anode system for cathodic corrosion protection.
  • Reinforced concrete structures are an integral part of the infrastructure in almost every country in the world.
  • many busy structures are also made of reinforced concrete, e.g. Parking garages, garages, highways, bridges, tunnels etc. A large number of these structures are used for 50 to 100 years (and sometimes even longer).
  • de-icing salts add to the reinforced concrete structures.
  • the de-icing salts are usually chloride-containing. In connection with water, solutions are created that trigger corrosion in the buildings. In many buildings, therefore, substantial, cost-intensive repair work must be carried out on the reinforcement after just 20-25 years.
  • the contaminated covering concrete is usually removed, the reinforcing steel cleaned and provided with new corrosion protection (e.g. on a polymer or cement basis).
  • new corrosion protection e.g. on a polymer or cement basis.
  • the repaired area often only lasts for a few years (due to mechanical, thermal and / or hygric incompatibilities), so that timely further repairs are required, especially when the covering concrete is heavily used. This causes high costs, represents a significant intervention in the structure and, last but not least, leads to restrictions on use during the repair.
  • cathodic corrosion protection (KKS) of buildings.
  • KS cathodic corrosion protection
  • cathodic corrosion protection is becoming increasingly important as an economical repair process for components that are at risk or corroded.
  • the principle of the electrochemical protection process is to influence the corrosion process of unalloyed or low-alloy steels (e.g. reinforcing steel) in an extensive electrolyte (soil, sea water, when used in reinforced concrete: concrete) by introducing a direct current.
  • This direct current causes a shift in the electrochemical potential of the metal to be protected in a negative direction, as a result of which the metal surface is cathodically polarized and harmful corrosion is prevented.
  • a permanent and corrosion-resistant anode To apply a protective current, a permanent and corrosion-resistant anode must first be coupled to the concrete and attached to the positive pole of a rectifier serving as a voltage source.
  • the negative pole of the DC voltage is connected to the steel to be protected (in the case of reinforced concrete to the reinforcement). After switching on the DC voltage, the steel to be protected is cathodically polarized and the steel corrosion is reduced to negligible rates.
  • the condition of the building, the structure or the pipeline or the corrosion of the steel can also be evaluated, monitored and regulated via a remote monitoring system. So that further corrosion or corrosion protection errors can be detected and remedied early.
  • the anode system be designed as large as possible in the vicinity of the steel element serving as the cathode, for example the reinforcing steel.
  • the anode systems used hitherto for example when using rod anodes or titanium ribbon anodes, or is very difficult to install, such as when using a reticulated titanium anode.
  • the application of a reticulated titanium anode to protect a reinforced concrete structure on the concrete is due to the inflexibility of the material and the necessary high Layer thicknesses of the embedding mortar are particularly laborious and time-consuming. This also leads to a high load.
  • Flat anode systems generate a more uniform electrical field, but due to the structure defined, they can hardly be adapted to the locally changing electrical conditions, for example in the form of deviations in the concrete cover or a different steel content, while band anodes are more flexible because they are narrower if necessary can be relocated.
  • the invention is therefore based on the object of specifying an anode system with a particularly simple and durable primary anode connection.
  • This object is achieved according to the invention in that the anode system comprises a biaxial or multiaxial scrim with a number of threads, at least some of the threads comprising carbon multifilaments and at least one thread comprising a primary anode.
  • the invention is based on the consideration that, in order to improve the feeding of the current into the anode system, in particular the contacting of the primary anode to the carbon anode should be facilitated and improved. At the same time, however, a flat and stable anode structure should be used for simple laying. It was recognized that particularly good feed-in can take place if the primary anode is incorporated or integrated into the anode structure. In order to simplify the manufacture of the anode system, there is no need to use a fabric in which the individual threads and thus the primary anodes would then have to be woven.
  • a scrim is used in which the individual threads are in an elongated form and thus there is no additional structural expansion and the orientation of the threads can also be defined specifically for the respective application.
  • the conductivity can differ from thread to thread, since this depends on the number of breaks in the carbon multifilaments.
  • the conductivity of the entire scrim is thus largely determined by the nodes and breaks in the carbon multifilaments.
  • At least one thread of the scrim comprises a primary anode.
  • the primary anode is essentially formed over the entire length of the thread.
  • scrims are understood to mean a flat structure which consists of several layers of stretched threads which run essentially parallel. The individual layers are placed on top of each other and fixed together at the crossing points. If the threads of different layers are oriented in two different directions, one speaks of a biaxial fabric, if several layers with multiple orientations are provided, as can be the case, for example, in a 3D fabric, a multiaxial fabric is referred to. In the context of this application, the term scrim is also to be understood to mean a grid which likewise has a corresponding structure.
  • a single stretched strand is understood as the thread of a scrim.
  • This thread can consist of a number of carbon multifilaments, which together form a thread or strand.
  • the primary anode is formed from platinum or titanium and optionally coated with a mixed metal oxide.
  • the primary anode is sewn into a thread made of carbon multifilaments or sewn onto such a thread.
  • the primary anode is wound around a thread.
  • a primary anode can also rest on the gaps or meshes. Accordingly, the primary anode can also be designed as a round, flat ribbon or grid anode. In principle, it is also possible for the primary anode to replace a thread made of carbon multifilaments.
  • the threads of adjacent layers are sewn together in an advantageous embodiment at the crossing points.
  • this mechanical connection enables both the production of a rigid scrim and the mobility of the scrim threads at the crossing points, which, depending on the application, enables both a rigid scrim and a flexible scrim that can be divided into any number of stages.
  • At least some of the threads comprise carbon multifilaments.
  • they are glued together and / or sewn with a circumferential fixing thread.
  • the carbon filaments and / or the carbon multifilaments and / or the threads and / or the scrim as a whole are impregnated and / or coated in a preferred embodiment in a preceding work step.
  • Another advantage of an impregnation is that by shrinking the base medium used for the impregnation, better contact is achieved between the primary anode and the threads or the scrim.
  • the scrim of the textile reinforcement can be particularly easily adapted to the ambient conditions at the place of use if the impregnation and there the base medium used for the impregnation is modified by adding additives to increase the electrical, mechanical and thermal properties.
  • additives for example, it is possible to increase the electrical properties, in particular the conductivity, by adding carbon nanotubes, metal particles, salts (or ionic compounds) or graphite, while the thermal properties can be influenced by adding metals, carbon and graphite particles .
  • hard materials for example in the form of silicon carbide, quartz and ceramics.
  • additives it is possible to modify the process parameters and possible processability of the scrim, in particular a carbon scrim. It is conceivable to use plasticizers, retarders or swelling agents to influence the properties of the fresh and solid mortar.
  • the addition of additives can ensure that the strength of the mortar in the area of the scrim is particularly high, while it is comparatively low on the surface. This strength gradient, which drops away from the scrim, enables the scrim to be used particularly flexibly.
  • the base material is preferably synthesized by radical polymerization from a monomer and a starter. It is now possible to add the additive to the monomer and / or the starter before the synthesis. This enables the impregnation to be modified even before the base material is synthesized. Additionally or alternatively, it is also possible to add the additive to the already synthesized base material before, as part of the impregnation and / or after the impregnation in the form of a sprinkling on the impregnated scrim.
  • the starter is applied to the scrim in a first process and only then is the monomer applied, so that the base material is synthesized directly on the scrim.
  • a polymethyl methacrylate as the base material for the impregnation has proven particularly advantageous. Since this base material can be introduced particularly well into the interstices of the scrim but also into the interstices of the fiber strands due to the low density.
  • the epoxy resins, styrene-butadiene rubbers and acrylates or polyurethanes mentioned above are also quite conceivable.
  • the surface of the impregnated carbon fabric is roughened and thus enlarged.
  • additives in the form of particles are added to the coating medium, which increase the surface area cause.
  • granite, quartz powder, cement stone or conductive particles can be used.
  • the enlarged surface leads to a non-positive and positive connection (reinforcing effect).
  • ionic compounds or concrete admixtures can also be used which influence the hardening reaction kinetics in order to increase the conductivity in the border area on the one hand and the mortar strength in the tissue environment on the other hand when using salts.
  • a coating can also be applied to the already impregnated carbon fabric that, like the particles, increases the surface. This coating can then either be the carrier medium for the particles or itself provide a higher bond. In a preferred embodiment, additives are also added to this coating medium to improve the electrical, thermal or mechanical properties before, during or after application to the impregnated carbon fabric.
  • the impregnation or coating can be applied in particular in the immersion bath process, an emulation process, a spray process or else coated or rolled.
  • the properties of the reinforcement but also of the mortar in the direct Reinforcement environment can be influenced.
  • curved, freely weathered and used structures can be permanently protected from steel corrosion and mechanically reinforced at the same time.
  • a particular advantage is that, with suitable modification of the mechanical properties, it can be achieved that the carbon fabric used here as a thin-layer textile concrete can provide sufficient load-bearing capacity or an increased load capacity even without the combination with cathodic corrosion protection.
  • the removal of thin old coverings that are no longer necessary for the load-bearing capacity (such as screed, asphalt or low-strength concrete) can lead to a reduction in the load, increased load capacity and greater clearance heights in parking garages.
  • the increase in strength near the fibers leads to an improvement in performance without causing very high levels of cracking. Furthermore, the addition of flow agents to the fiber can improve the penetration into the fabric.
  • the main advantages of the coating medium used are the improvement of the electrical, chemical and mechanical properties of the entire system, in particular the high mechanical strength and load absorption of the materials used (e.g. static and dynamic tensile, adhesive and Shear loads), the long-term resistance to environmental influences, ie chemical inertness and temperature resistance in a temperature range from -20 ° C to 80 ° C.
  • the load capacity behavior can be improved in the larger temperature range.
  • the advantages lie in the flexible processability and deformability (drapability) with sufficient rigidity for laying the textile reinforcement. Connections across corners and edges can be made non-positively and electrically conductive. The rigidity also enables easy application during installation.
  • the threads of a layer are arranged at a distance from one another in order to optimally embed the anode system in the concrete and thus particularly good power transmission.
  • This creates free spaces between the threads that can be filled with concrete, which completely surrounds the threads with concrete.
  • a distance between the threads of 5 - 100 mm is particularly advantageous, on the one hand to create enough space for mortar or concrete in the spaces and on the other hand to be able to provide a sufficiently dense anode scrim to meet the required electrical properties.
  • the scrim comprises two layers, the threads of one layer being arranged at a distance from one another. With this biaxial arrangement of the layers, there are square spaces which are delimited by the adjacent threads of both layers and can be filled in by concrete.
  • the scrim has a basis weight per layer of 100-1000 g / m 2 , preferably in Range from 350-650g / m 2 .
  • the advantages achieved by the invention consist in particular in that the embedding of the primary anode in the scrim enables a particularly safe and oxidation-free introduction of currents into the anode system at several points.
  • the use of a scrim enables particularly simple manufacture of the anode system in advance and also particularly easy installation on site.
  • the use of special coatings, different distances in the threads and variation in the number of layers makes it particularly easy to adapt the anode system to the application and the conditions there.
  • the clutch 1 after Fig. 1 comprises a plurality of threads 2 or strands, which are arranged in two planes.
  • Each level comprises a number of threads 2 which are spaced apart and essentially parallel to one another.
  • Each of these threads 2 comprises a number of carbon multifilaments, which in the present exemplary embodiment have been glued to form an elongated strand. However, it is also conceivable that these carbon multifilaments are sewn into a strand or connected in some other way.
  • the threads 2 of two planes are essentially orthogonal to one another, which is why a lattice structure with square spaces is formed.
  • the threads 2 are fixed at the crossing points 4 with a continuous sewing thread 6, but can also be glued or connected to one another in another way.
  • the planes of the scrim 1 do not necessarily have to be arranged orthogonally to one another, but, depending on the application, can also be arranged offset at a different angle. It is also conceivable that more than two levels can be provided.
  • a ribbon-shaped primary anode 8 is sewn along the entire length on a thread 2, whereby the anode system can be supplied with current over the entire length in contrast to contacting in a single point.
  • the primary anode 8 is sewn into a thread 2 and is therefore essentially completely surrounded by carbon multifilaments.
  • an impregnation 10 and then a coating are applied to the scrim 1.
  • a scrim 1 for an anode system can be provided, which has optimal mechanical, electrical and thermal properties for the respective application and location.
  • a thread 2 of a scrim is shown in cross section.
  • the thread 2 comprises a large number of individual carbon multifilaments 12, each of which has between several 1,000 and up to 100,000 individual filaments.
  • the thread 2 is in the embodiment Fig. 2 provided with an impregnation 10, to which one or more additives 14 were added in the impregnation process in order to improve the electrical, mechanical or also thermal properties.
  • the thread 2 has been coated with a coating medium 16.
