Definitions

  • This invention has reference to counteracting bio-fouling on surfaces in aquatic environments by letting the surface have a ribbed structure.
  • bio-fouling Surfaces which are immersed into the sea will immediately be covered by bio-fouling.
  • bio-fouling First a thin layer of bio-polymers, bacteria and unicellular algae is formed, followed by a thick layer of invertebrates for instance acorn barnacles and mussels.
  • bio-fouling is a serious problem for shipping because the increased water resistance has an influence on the fuel consumption.
  • bio-fouling has negative consequences for flows through piping systems and for exchange speeds in heat exchangers.
  • the marine cultivation industry is also affected negatively by bio-fouling. Net bags, cultivation cages, rafts and ropes will often be strongly overgrown which will cause increased mortality and high cleaning costs. Increased weight and cleaning as a result of bio-fouling are also problems within offshore industry.
  • TBT paints Tributyltin
  • pleasure boats in most cases copper-based paints.
  • Increased environment-consciousness of the risk of spreading these very poisonous substances in the sea has resulted in local prohibitions against their use.
  • a global restriction against the use of TBT paints for commercial shipping is expected to come into force in 2008.
  • FIG. 1 shows a section of a foil greatly magnified.
  • FIG. 2 shows, greatly magnified, a ribbed structure directly on a surface which is to be protected.
  • [0008] 1 indicates a carrying foil of plastic with a high melting-point. This foil is laminated with a second foil 2 of a more easily fusible plastic. 3 indicates a self-adhesive glue. From the easily fusible plastic a big number of ribs 4 run out. At the base they can be for instance 0.15 millimetres wide and one millimetre high. They have an outward narrowing form. The ribs are placed close to each other in parallel rows. The ribs have a rounded transition at the base.
  • the foil After manufacturing the foil can be rolled on rolls. Protective paper which can be pulled off is not necessary since the edges of the ribs reach the self-adhesive layer when rolled up.
  • the inside can consist of a non-woven material which is well fastened to the carrying foil.
  • the non-woven material can easily be glued and in this case it is the intention that the object which is to be protected or the foil can be provided with glue and that after that the foil is pressed on to the object.
  • the foil If the foil is to be suitable for small boats, for instance pleasure boats of plastic where the surface of the hull is strongly curved, the foil can be a little elastic, which many plastics allow. In order to prevent air-bubbles between the hull and the foil, the foil can be perforated.
  • the production of the foil can be made so that a laminate of carrying foil of not thermoplastic material or of a plastic with a high melting point is laminated with a thermoplastic with a low melting point.
  • the laminate is heated and pressed against a rotating cylinder provided with many grooves in which plastic material is pressed out and forms ribs. After the plastic has come into the grooves the plastic is cooled and when the carrying foil is rolled off from the cylinder the ribs leave the grooves.
  • the foil can be given various shapes with regard to the use of material, the distance between the ribs, height, thickness, inclination and cross-section of the ribs.
  • the ribs can be made to be at right angles to the surface and with an equal distance between them. Because the ribs are made by pressing from a foil they are safely connected with it and cannot come loose. Owing to the outward narrowing form they are strong and owing to the open form the foil can be easily cleaned.
  • the ribs are indicated by 5 , They were made directly on a hull 6 .
  • This can be made by rolling a cylinder of adjacent round razor blades under pressure against the surface which has first been smeared with the material which is to form the ribs.
  • the rolling can be made with a cold cylinder on a polymer which has not had time to harden or with a heated cylinder on a hardened polymer.
  • a great height of the ribs affects the friction against the water negatively.
  • the height of the ribs is of little importance.
