Definitions

  • the granular wax material may m fact be applied m basically the same manner as conventionally used m connection with various types of plastic coating based on the use of granular plastics.
  • spray painting in causing a flow of small wax granules to pass through a heater unit from a storage container for further delivery of the now melted wax to a discharge spray nozzle.
  • the powder is currently injected into a blowlamp flame or a flow of hot air directed against the surface to be treated, and it is envisaged that m particular m connection with a protective surface treatment of large, stationary outdoor structures such as building surfaces, roads and runways, bridges, historical monuments and inner details thereof, etc., it will be possible to use the equipment m such a controlled manner that a surface portion being treated is initially subjected merely to the heating action of the flame or the flow of hot air, so as to be preheated for evaporation of moisture prior to a following initiation of the said powder injection.
  • the powder may become a paint when coloured as desired, or a visually and environmentally neutral, highly, protective coating or impregnation, addressing all structures and not least all of the climatically endangered, ancient monuments throughout the world.
  • the same interest is to be paid to any modern "monument", be it a gravestone, a building surface or a sewer pipe among extremely many other possibilities.
  • a fully corresponding application technique may be used in connection with the treatment of minor articles, e.g. in connection with car painting or undercarriage rust protection.
  • Another possibility is to use, for smaller articles, the "whirl sintering" method, according to which a heated article is lowered into an air fluidized whirling mass of plastic powder or granules, such that the hot article surface will "catch” the particles hitting it, resulting m a rapidly obtained full coating of the article.
  • the low friction property of the wax material may be relevant even with respect to air friction on aeroplanes and windmill wings.
  • another relevant property is that an ice formation on a wax coating will not stick very firmly to the coated surface, such that when icing occurs, the ice is likely to get loosened by a r pressure or centrifugal forces.
  • the hard wax will be fully usable for such purposes because it is fully climate resistant even during warm periods .
  • the indicated low- friction characteristic of the wax may be advantageous also in other respects, e.g. in connection with slip properties of various types of shaping moulds.
  • the "hard wax” does not contain water or solvents for later disappearance in a moulded structure, and the hot and melted wax is very effectively sticking to any surface to which it is supplied. It has been realized that these facts will account for another important application of the material, viz. as a joining or pointing material between interspaced solid items such as paving stones or tiles.
  • the wax with or without a filler material, may be used as a joining material, e.g. based on a granular material being swept into the interspaces between the laid out items and then activated by heating by means of an air heater or a blowlamp.
  • non-shrinking wax material will be highly applicable for the filling out of moulding cavi- ties, e.g. in connection with a moulding out of holes in a concrete floor or stair steps for a firm anchoring of the bottom end of railing poles therein.
  • Any visible surface of the wax material, with or without a filler material, may be smoothened out by means of a heated smoothening blade on a relevant hand tool.
  • the material will be perfectly suited as a repair mass in general, e.g. for floors in wet rooms.
  • the wax material is basically electrically insulating, but it can be made conducting with a suffi- cient addition of conductive material . This implies that it is possible to build up electronic substructures that are totally harmless when they are later on destructed, this otherwise being a marked problem.
  • the wax material whether alone or with an included filler material, has been found to have a noise damping effect on whichever surface it is applied.
  • the wax is well usable as a thin protective coating on different types of surfaces. In the building sector it can serve as a mechanical protection on finished surface areas, for protection against damage during the remaining finishing work in the building. In the metal industry and particularly in regions with high air humidity, the wax is usable for corrosion protection even of raw materials and intermediate products; many working operations may be done despite the presence of a thin surface film.
  • the wax or "wax concrete" is well suited in connection with details pertaining to roads liable to be salted during winter, as it is resistant to salt water. Moreover, a mixture of wax coated sand and salt particles seems to have good an- tiicing properties when used as a stabilized surface layer, e.g. on stair steps such as in fire escape stairs.
  • wax In connection with sand or other granular material used as filler material or in coated condition, some 20-30% (by volume) of wax will often be suitable.
  • the wax despite its character of a highly rigid and cli- mate resistant material, will still be a combustible material, usable e.g. in kindling briquettes and torches and as a binder in straw briquettes and the like.
  • a packag- ing material either by itself e.g. as carrier plates or trays for foodstuff articles or as a coating on other packaging materials, and in both cases it will end up in the refuse system, in which it is directly usef l, because in the asso- ciated refuse disposal plants it will represent a high thermal value when actively burnt, already because it cannot possibly be soaked by water.
