Definitions

  • the present invention relates to a process allowing, in winter season, the application and the polymerization of paints and coatings at a predetermined temperature higher than the ambient temperature for the internal coating of tanks or tanks of ships called to transport liquid products.
  • the invention which overcomes such drawbacks therefore allows, during the winter season, the application and polymerization of paints or coatings in ships' tanks.
  • the method consists in wrapping the outer walls of the tanks to be treated with a layer of thermally insulating material consisting of polyurethane foam in panels or sprayed and in heating the interior of said tanks and the volumes delimited by the adjacent capacities to maintain in them a sufficient temperature during the application and the polymerization of the paint.
  • Vessels transporting liquid products have several tanks or cisterns, some of which are used, for example, to transport chemical or food products.
  • the interior walls of these tanks must therefore be coated with solvent-based epoxy paints.
  • These tanks have at least one wall exposed to the air (central tank) or two walls exposed to the air and to sea water in different proportions of surfaces.
  • FIG 1 a metal sheet 2 plating constituting the outer wall of a side tank 1 of a ship in which a temperature above 10 ° C must be maintained on the one hand during the application of paint 3 on the inner face of the sheet 2 and on the other hand during the entire polymerization phase of this paint which lasts several days.
  • the ambient temperature inside the tank and in the volumes delimited by the capacities adjacent to the tank to be treated being maintained by blowing hot air, a layer is applied to the external face of the metal sheet 2.
  • this insulating layer 4 is formed of foam panels 6 held by plastic supports 7 directly glued to the metal sheet 2 and by fixing washers 8 or possibly by holding magnets. The edges of the end panels, as well as the panels between them, are sealed with sprayed foam 9, in order to prevent water and air infiltration.
  • the part of the hull of the ship located under the waterline 5 in contact with seawater is isolated by sprayed foam 10 which has the advantage of perfectly adhering to the metal sheet 2 which makes it possible to launch the ship and to continue the work afloat, while allowing the polymerization of the paint to be carried out, while maintaining the temperature inside the treated tank above the critical point. If the sea water temperature is always days above 10 ° C, the insulation stops at the waterline.
  • the procedure is the same by applying foam panels 6 embedded between the raised structures 11 of the hull and held by the plastic supports 7 and the fixing washers 8 or by the holding magnets.
  • the edges of the end panels, as well as the panels between them, are also sealed by sprayed foam 9.
  • the raised structures 11 are coated with a polyane film 12 on which is sprayed insulating foam 13 to form a tight connection with the panels 6 and avoid thermal bridges; the polyane film facilitating the removal of the sprayed foam.
  • polyurethane foam has the advantage of being an easy-to-install and water-repellent product while having mechanical strength suitable for the movement of personnel and subsequent work by the installation of plywood plates ensuring distribution of the load.
  • This process of insulating the external walls of the tanks of ships therefore makes it possible, during the winter period, to maintain inside said tanks a temperature sufficient for the application and polymerization of paints or coatings and this whatever the temperature of the air and sea water.
