Definitions

  • the invention relates to an arrangement on a printing press with a process agent cleaning device and a method for cleaning process fluid.
  • Printing presses use a number of process agents. For example, require offset printing machines that are operated in wet offset next to the ink process water, the so-called dampening solution or fountain solution.
  • the fountain solution used is intended to wet the non-printing areas of the printing plate and thus prevent ink acceptance in these areas.
  • processing agents such as e.g. Detergents are used, which are used in particular for cleaning printing cylinders and blanket cylinders.
  • a common composition of dampening solution is a proportion of more than 80% by volume of water, up to 10% by volume of chemical additives and up to 15% by volume of isopropanol.
  • the chemical additives serve u.a. the lowering of the surface tension on a pressure-technically favorable range, containment of the microorganism formation by means of biocides, prevention of corrosion at steel components of the printing machine by means of corrosion inhibitors, etc.
  • the isopropanol has, inter alia, a viscosity-increasing and a surface tension-lowering effect.
  • Isopropanol is more volatile than other fountain solution ingredients, resulting in uneven evaporation of isopropanol and others
  • Dampening solution components especially at higher temperatures, may result in a change in the mixing ratio in the dampening solution.
  • the dampening solution composition in particular the proportion of isopropanol, must therefore be monitored on the one hand and readjusted accordingly.
  • Other process agents used on printing presses are frequently tempered.
  • printing presses are usually equipped with temperature control. These can be used both for the temperature control of the process agent and for the temperature control of the functionally essential parts of the printing press, in particular the printing cylinder. Tempering in the sense will usually mean cooling, but is also quite a heating into consideration, for example, in the start-up phase of a printing press.
  • Isopropanol is due to cost and environmental aspects increasingly in the criticism, since such additives are considered harmful to health and the environment.
  • a goal of the previous and further development is therefore, an economical use of dampening water, in particular with the contained alcohol constituents.
