Definitions

  • the invention relates to profiles and joining means in general for panels and conduits of insulating material, preferably polyurethane foam, in particular for the conveyance of air for environmental conditioning, treated with silver ions.
  • Said polyurethane insulating conduits are utilized, instead, for example, to maintain the temperature in systems for the conveyance of hot and cold air in winter and summer conditioning systems.
  • One of the uses of said panels and conduits is in hospital organizations, in foodstuff production plants, in semiconductor production plants and in general in rooms where particular hygienic conditions must be respected.
  • said panels and said conduits undergo frequent washing treatments. These treatments impose a stop to the activity or use of the rooms in which said panels and/or conduits are installed with expenditure of energy and sometimes, not succeeding, despite the washing, to reach the desired hygienic conditions.
  • silver ions have very potent antimicrobial properties.
  • silver ions are an active antimicrobial agent for at least 10 years and to obtain an antibacterial effect, the silver ions must be available in solution on the bacterial surface.
  • the silver ions destroy bacteria instantly, blocking the enzymatic respiratory system and altering the microbial DNA and the cell wall, while they do not have toxic effects on human cells in vivo.
  • Insulating panels and conduits have been designed made of polyurethane with covers realized with laminas of metallic, plastic or paper material with silver ions applied to the surface of the covering laminas of the panel and/or conduit facing the interior of the room or the conduit where certain hygienic conditions must be respected.
  • Said panels with silver ions are installed using commonly known profiles - made of various materials, preferably aluminum or plastic. Said panels with silver ions installed, for example, to maintain the temperature in cold rooms, are secured to the walls of the cold rooms by means of commonly known profiles made of aluminum or plastic.
  • Said conduits with silver ions are realized both widthways and lengthways by joining said panels by means of commonly known profiles made of aluminum or plastic.
  • the fastening of said profiles and joining means in general is realized by means of fitting through the application of pressure.
  • the actual form of the profiles and joining means in general, the pressure application methods by which said profiles and said fastening means are fastened to said panels with silver irons allow the microbes to hide in the various interstices and reduce the surface area of said panels treated with silver ions since part of the profile bars or the fastening means overlaps the surface of said panel with silver ions, reducing the antimicrobial capacity of said panels and said conduits. Disclosure of Invention
  • the aim of this invention is to realize profiles and joining means in general for said panels and/or conduits with at least the internal surface with ions able to perform an antimicrobial function, rendering possible a reduction in the frequency of the washing treatments which are presently effected for the commonly known panels and conduits.
  • This aim is achieved by means of the use of silver ions applied to the surface of profiles and/or joining means in general for insulating panels and/or conduits which must respect certain hygienic conditions.
  • the bacteria contained in the air present inside said rooms or said conduits, upon coming into contact with the surface of said profiles and/or means of connecting said panels and/or said conduits, treated with silver ions, are destroyed thanks to the antimicrobial properties of said silver ions.
  • - figure 1 shows a perspective view of a profile bar
  • FIG. 2 shows a perspective view of a means of joining the conduit in
  • 1 denotes the presence of silver ions on the surface of at least one side of the profile or joining means of said panels or said conduits.
  • the antimicrobial capacity of the silver ions occurs upon the bacteria's contact with the silver ions.
  • Said ions are applied to the surface of the profiles and/or joining means present in the room or conduit concerned.
  • the silver ions are applied to the surface of the profiles and/or connecting means made of metallic material by adding a silver ion solution to the galvanization bath used for the profiles and/or connecting means in question.
