Definitions

  • Ambient air is composed of molecules of gases that can often become positively or negatively charged due to static electricity discharges and/or other natural causes.
  • High concentrations of negatively charged molecules often referred to as “negative ions” or “minus ions” are often found near waterfalls, country meadows, beaches and mountains.
  • High concentrations of positively charged molecules often referred to as “positive ions” are often found in polluted areas, such as, cities, office buildings, factories and other urban settings.
  • Air inside buildings tends to become stale and unpleasant to breathe as a result of, in part, the depletion of the negative ion content in the air.
  • Various conventional air ionizers have been developed to counteract the depletion of negative ions and also to purify air by causing the precipitation of particulate contaminants out of the air, and onto nearby surfaces.
  • Such conventional air ionizers typically include pointed electrodes that are' connected to high voltage supplies to produce intense electrical fields adjacent to the pointed electrodes. Neutral gas molecules in the vicinity of these intense electrical fields are transformed to positive or negative ions, depending on the polarity of the high voltages on the electrodes. Electrostatic repulsions from the similarly charged electrodes, along with air blowers, disperse the negatively charged ions throughout the room to cause precipitation of particulate contaminants from the air and to promote the concomitant beneficial physiological effects.
  • Humidity control apparatus are also suggested as a negatively charged ion generation system through adjustment of the amount of moisture included within the air so as to control the ion exchanging rate.
  • volcanic ash sediment is employed that includes titanium oxide, which reacts with hydrogen or oxygen generating active oxygen species or oxygen free radicals. The generation of active oxygen species, provides an air filter.

In other embodiments, a wear layer is positioned atop the surface so as to locate the exposed portion of the electrically polarizable particles no more than one millimeter from the surface.

  • a method for generating negative ions includes positioning a flooring cover within a building, where the floor covering includes a surface that forms a boundary with the ambient environment of the building.
  • the floor covering comprises an effective quantity of pyroelectrically polarizable material disposed no more than one millimeter from the surface, so that when a person or thing travels across that surface so as to frictionally heat the pyroelectrically polarizable material, negative ions are generated.
  • a person or thing traverses a flooring cover so as to frictionally engage a surface that forms a boundary with the ambient environment so that frictional heating of a pyroelectrically polarizable material located substantially below the surface causes negative ions to be generated by the floor covering.

L'invention concerne également un procédé de génération d'ions négatifs qui consiste à positionner un revêtement de sol à l'intérieur d'un bâtiment, le revêtement de sol comprenant une surface qui forme une limite avec l'environnement ambiant du bâtiment. Le revêtement de sol comprend une quantité efficace de matériau pyroélectriquement polarisable disposé à pas plus d'un millimètre de la surface, de sorte que lorsqu'une personne ou un objet se déplace sur ladite surface de manière à chauffer par frottement le matériau pyroélectriquement polarisable, des ions négatifs sont générés. Ladite génération d'ions négatifs neutralise ou réduit les odeurs, les bactéries en suspension dans l'air, les spores de moisissures, les pollens et autres particules nocives en suspension dans l'air.
