Definitions

  • the invention relates to a method for removing surfaces, such as dirt, corrosion or lacquer layers, in which solid, water-containing blasting material is allowed to strike the surface to be removed in a fluid jet at a predetermined speed.
  • Such methods are used, for example, for cleaning facades, stone surfaces or the like.
  • sandblasting processes are known which are used for removing paint and corrosion layers, for example on bridge railings.
  • this method no water is added to the jet, so that here too the environment is highly polluted while working with this method. On the one hand, this happens due to the dust escaping into the ambient air, which can directly lead to health hazards, on the other hand, the blasting material used is also in an uncontrolled manner in the wider environment of the construction site, so that the blasting material used is often no longer removed for economic reasons becomes.
  • the invention has for its object to avoid the aforementioned disadvantages and in particular a method of the type mentioned for Ver to provide, which limits the environmental impact to a minimum.
  • This object is achieved in that water is frozen using ice-forming nuclei and is supplied in the form of ice particles to the fluid jet as blasting material.
  • the ice particles required for the process can be produced by crushing coarse ice. However, it is possible that the ice particles are generated by freezing smaller amounts of water, such as drops, balls or the like.
  • water will freeze with the help of ice-forming germs.
  • this can be done by using artificial germs such as dust particles; however, it is also possible to freeze water directly, which usually contains ice-forming germs.
  • ice blocks that are formed are then crushed into ice particles.
  • the ice particles can also be generated in their final size by freezing.
  • the ice particles present in this way are sucked in and mixed, for example by means of compressed air, and sprayed onto the surface to be removed together with the compressed air jet.
  • compressed air is not essential, it is rather important that the ice particles, provided with sufficient kinetic energy, strike the surface to be removed.
