Definitions

  • the present patent concerns abrasive products and devices for cleaning and/or disinfection of surfaces in general, and in particular concerns a new detergent and disinfectant abrasive product, comprising sodium bicarbonate, in powder and/or in granules, added to disinfectant agents and/or biocides, for industrial and/or domestic use, and relative application process and devices.
  • the new product is applied effectively and usefully in appropriately modified sandblasters or pressure washers.
  • the need often arises to thoroughly clean the surfaces by removing the substances deposited on them, such as oil, grease, organic or inorganic substances of various type, and to disinfect the surfaces themselves in order to limit the proliferation of bacteria and prevent infections from spreading.
  • the disinfectant product For adequate disinfection, the disinfectant product must then be applied and, lastly, at least one further rinsing operation must be performed.
  • hot water creates the ideal conditions for rapid resumption of bacterial proliferation on the surfaces treated.
  • a further -drawback deriving from use of the known detergent products consists in the high concentration of surface-active agents or other type of solvents present in said products, which are often harmful for humans who, without noticing, inhale or even swallow large quantities thereof.
  • the waste water containing surface-active agents requires specific and costly purification treatment, using activated carbon filters or special membranes, since the surface-active agents, which create very stable emulsions, are not removed by traditional treatment in oil separators.
  • the cleaning method in which substances firmly adhering to the surfaces to be cleaned arc removed by abrasion is also known.
  • Said method commonly performed in known equipment such as sandblasters or pressure washers, consists substantially in blasting a large mass of granules of sand or other solid material, at high speed, against the contaminated surfaces.
  • a flow of air or water under pressure sucks the sand or abrasive material in granules from a tank and conveys it to a delivery nozzle from which the granules arc emitted at high speed.
  • Some sandblasting processes include the use of water in addition to air and abrasive material in granules in order to more effectively remove the particles detached! Said physical method is frequently used for example for the removal of paints, grease, oil etc.
  • the subject of the present patent is a new type of detergent and disinfectant abrasive product for surfaces in general, which can be used particularly in sandblasting machines or pressure washers, for example appropriately modified, and relative process and devices for application of the same, wherein said product comprises, in the form of a solid mixture, sodium bicarbonate, in powder or granules, added to disinfectant agents and/or biocides.
  • the main aim of the present invention is to obtain high efficiency in mechanical removal of substances adhering to surfaces in general and, simultaneously, in cleaning and disinfection of said surfaces.
  • a further important object of the present invention is to eliminate the polluting load in the waste water, since the product does not contain surface- activc agents.
  • a further object of the present invention is to guarantee a lasting disinfectant and anti-bacterial action, preventing resumption of bacterial proliferation on the surfaces treated.
  • a further important advantage of the present invention also consists in the considerable reduction in cleaning times and therefore in the relative labour costs, since the new product simultaneously performs, in one single application-, the abrasive action, the detergent action and the disinfectant and/or biocide action.
  • a further advantage deriving from use of the present invention lies in that energy costs are reduced, since the effectiveness of the product is guaranteed also by applying it with air and/or non-heated water and therefore without requiring the use of hot water.
  • the product is substantially a solid mixture comprising sodium bicarbonate, in powder -or in granules, added to disinfectant agents and/or biocides in a variable quantity according to the type of active ingredient used.
  • the disinfectant agent is present in a quantity of 5% and preferably between 0.5% and 20%.
  • Sodium bicarbonate has an excellent detergent, degreasing and deodorant action while disinfection is performed by the biocide.
  • the new product can be used in the solid state, in a powder or granular form, and is applied to the surface to be treated by means of systems with air and/or water under pressure, thus also performing the abrasive action.
  • the application method exploits the pressure of the air and/or water to maximise the effectiveness of the detergent and abrasive action performed by the powder or granules of sodium bicarbonate.
  • the new product can also comprise further substances aiding the detergent and/or disinfectant action and/or further aromatizing or perfuming agents and/or medical products for specific applications in particular environments, such as hospitals and veterinary surgeries, in the presence of infective agents etc.
  • the new product is applied in ohe single solution, therefore reducing the successive repetitions required when applying the known detergent and disinfectant products.
  • the antibacterial effectiveness is maintained for longer because using non-heated water instead of hot water avoids the creation of environmental conditions favourable to rapid resumption of bacterial proliferation.
  • Said abrasive product will be applied to surfaces in general using new equipment like dedicated sandblasters or pressure washers.
  • Said new equipment has the innovative aspect of using compressed air for delivery of the abrasive product, i.e. said solid mixture of bicarbonate with or without disinfectant agents, from the head of the sandblaster or pressure washer.
  • .product can be adapted to existing pressurised water systems by means of accessories or adaptation kits described below.
  • the new equipment for application of the new abrasive product solves this problem as it comprises at least one hopper/tank to contain the abrasive product, i.e. bicarbonate with the addition of disinfectant agents, at least one chamber or Venturi tube fed, via one or more valves, with compressed air generated by a small compressor or taken from an external source, if present.
  • abrasive product i.e. bicarbonate with the addition of disinfectant agents
  • at least one chamber or Venturi tube fed, via one or more valves with compressed air generated by a small compressor or taken from an external source, if present.
  • the new equipment furthermore comprises at least two switches, one of which for general operation and one for excluding the abrasive product during the rinsing phases.

Abstract

L'invention concerne un nouveau produit abrasif pour surfaces en général comprenant, sous la forme d'un mélange solide, du bicarbonate de sodium en poudre et/ou en granulés ajouté à un agent désinfectant et/ou à un biocide et/ou à des substances ayant une action détergente et/ou aromatisante et/ou parfumante et/ou à un ou plusieurs produit(s) médical/aux ayant une action spécifique. Le procédé d'application permet d'utiliser l'équipement avec de l'air et/ou de l'eau sous pression, ladite eau étant utilisée à température ambiante, et comprend un dispositif destiné à produire de l'air comprimé qui, via au moins une chambre ou un tube de venturi et une ou plusieurs valve(s), retire ledit produit abrasif d'un réservoir en le mesurant, et le propulse vers l'extérieur.
