Definitions

  • the invention relates to a method for cleaning surfaces, in particular sensitive surfaces that are contaminated by environmental influences.
  • the process described here is a further development of the cleaning process for surfaces in accordance with European Patent No. 0 171 448.
  • blasting material a substance suitable as blasting material
  • sharp-edged blasting material such as sand (a silicon compound), quartz, corundum or fly ash.
  • the object of the invention is to overcome the shortcomings of the known method that occur in the cleaning of highly sensitive surfaces, and thus also to enable the cleaning of very sensitive objects.
  • blasting material with low hardness has the advantage that, when blasting sensitive surfaces, they greatly enhance the cleaning effect of the water / gas jet, but because of their minimum hardness, which is generally lower than the hardness of the materials to be cleaned , clean them properly, but do not destroy them.
  • the kinematics of the collision processes taking place during cleaning play a decisive role. Due to its mass, the mineral blasting material is capable of absorbing kinetic energy and releasing it on impact on the surface to be cleaned, and thus of detaching layers that are not integrally connected to the surface, namely impurities. However, before the object to be cleaned can be removed itself, the mineral particles will release their inert kinetic energy by bursting and / or being thrown back by the surface to be cleaned.
  • Dolomite which has a double carbonate as a rock-forming mineral, is preferably used as a suitable shot.
  • the hardness of this material is 3.5.
  • Other materials based on simple carbonates are also used for this process. These are e.g. B. limestone, but also lime itself.
  • this method is not restricted to the mineral blasting materials mentioned above, but rather can be combined with all substances with a hardness of four or less.
  • the grain size of the blasting material used should not exceed 1 mm in diameter. Diameters between 0.01 and 0.8 mm can guarantee an optimal cleaning result depending on the nature of the surface to be cleaned. The cleaning process using mineral blasting material in dust form is particularly uncritical. Diameters from 0.01 to 0.05 mm are preferred.
  • the device shown in the figure which is generally referred to as "mixing head 10" and for carrying out the invention Suitable for the method has two pipe sockets with central axes 12, 14 on the feed side, through which the jet components are introduced into the mixing head 10.
  • a pressurized water / air mixture is fed on the axis 12 to the mixing area 16 of the mixing head 10 and a blasting material / air mixture under pressure on the axis 14.
  • the ratio of the two pressures to one another differs from application to application.
  • the two pipe sockets can be supplied by their own, but also by a common pressure source via adjustable pressure sources.
  • the two jet parts mix to form an overall jet which, as described in EU-PS 0 171 448, has a rotational movement.
  • the total jet then emerges through the nozzle area 18 of the mixing head 10 along the axis 20 and strikes the surface 22 of an object to be cleaned.
  • mineral blasting materials with a Mohs hardness of less than or equal to four are introduced into the mixing head 10 along the axis 14, even paintings can be cleaned extremely gently.
  • highly sensitive surfaces 22 can mineral substances such as dolomite, calcite, limestone are used.
  • the particle size should not exceed 1 mm in diameter. With diameter sizes from 0.01 to 0.8 mm, almost all surfaces and especially sensitive surfaces can be cleaned.
  • the method according to the invention can also be carried out with substances of another type which have a Mohs hardness of less than or equal to four.
