  • These CO 2 snow particles are produced using a suitable process and nozzle technology in a specific size. They are added in a multistage mixing chamber to a stream of compressed air by means of a jet nozzle. In doing so, a homogeneous free jet is created with which surfaces can be cleaned and pretreated.
  • the thermal effect of the CO 2 snow jet causes shock freezing of the surface contamination. Due to the different coefficients of thermal expansion of the surface and the surface, the use of CO 2 snow blasting leads to embrittlement of the contamination. This makes them easy to detach from the surface. Furthermore, the use of compressed air as transport gas and the design of the irradiation nozzle to mechanical actions, which remove the embrittled contaminants from the surface. The sublimation expansion of CO 2 also contributes to this, which contributes to the detachment and removal of the contamination from the surface.
  • the chemical action of the CO 2 snow jet further consists of surface contamination removal processes caused by the carbon dioxide gaseous after the sublimation process. This has a further positive influence on the removal of surface contaminants and supports the removal of the contamination.

Therefore, the CO 2 snow blasting is suitable For example, especially good for plastic-based surfaces. Furthermore, the CO 2 snow blasting is particularly well suited for contaminated with fats, oils or other organic substances surfaces, since these contaminants shock-frozen due to the low temperatures of CO 2 and embrittle and by means of a suction device (not shown) can be sucked.

  • the three described sub-modules 33, 34, 35 have in common that they cause an incorporation of oxygen atoms in the uppermost surface layers. Furthermore, any lightly bound foreign layers present on the surface are removed by means of these submodules. In this case, the properties of the surfaces are changed in terms of appearance, consistency and geometry only in small, not visible to the naked eye measure. This is accompanied by the increase of the physical surface energy to values which are advantageous for further processing.
