Definitions

  • the present invention describes a method and a device for removing contaminants, including inorganic contaminants, such as dust and sand, and organic contaminants, such as mold components, mold spores and bacteria, and for disinfection, ie to reduce the number of germs capable of reproduction, such as for example fungi, spores or bacteria, archival materials, in particular archival materials in bound form, such as books.
  • contaminants including inorganic contaminants, such as dust and sand, and organic contaminants, such as mold components, mold spores and bacteria
  • archival materials in particular archival materials in bound form, such as books.
  • Paper and the chemicals contained in paper and in the cover materials, such as adhesives, are an almost ideal carrier and breeding ground for many molds.
  • the main causes of the growth and multiplication processes of mold in archives are dust-laden or soiled archived material, excessive relative humidity, increased object moisture in the archived material or accidents.
  • Another possibility for combating mold is sterilization by irradiation with gamma rays, for example cobalt 60, or fumigation with ethylene oxide. Mold spores are killed with a sufficiently high dose of gamma rays. When irradiated, however, the written material loses a considerable part of its strength. A precise assessment of the risk is therefore required as to whether infected papers are at all suitable for irradiation. Fumigation with ethylene oxide has the disadvantage that residues of ethylene oxide are harmful and carcinogenic.

  • the arrangement of a sieve-like surface between the archives and the device for controlling the direction and / or speed of flow is particularly advantageous if the device has only one or a few openings through which the treatment liquid flows centrally into the container. With an appropriate arrangement of the openings on the screen-like surface, the flow of the treatment liquid in the container can be controlled in such a way that a uniform, ascending flow is formed which rises along the mandrel and flows evenly through the archival material.
