Definitions

  • these PC coatings can also be hydrophilic, e.g., water wetting with a contact angle with water of generally less than 20 degrees.
  • the hydrophilicity of the PC coatings helps reduce fogging, i.e., the accumulation of water droplets on the coating, which fogging can decrease visible light transmission and visibility through the coated substrate.
  • the coated substrate 12 can be rinsed with conditioned water to flush at least some of the dirt, grime, organic materials, and/or inorganic materials off of the hydrophilic and/or photoactive, e.g., coated, surface.
  • conditioned water refers to water being low in dissolved minerals and/or inorganic materials.
  • the conditioned water can be formed by removing at least some of the dissolved minerals and/or inorganic materials, such as dissolved inorganic ions, from non-conditioned water.

Abstract

La présente invention concerne un procédé de nettoyage d'une surface photoactive et/ou hydrophile. Ledit procédé consiste à mettre en contact la surface avec de l'eau conditionnée et éventuellement avec une solution d'agent de nettoyage. L'invention concerne un dispositif de nettoyage d'une surface photoactive et/ou hydrophile qui comprend un logement présentant une entrée et une sortie, une première chambre et une seconde chambre éventuelle située dans le logement, un passage d'écoulement s'étendant dans le logement entre l'entrée et la sortie, et une vanne de sélection conçue pour sélectivement placer le passage d'écoulement en communication fluidique avec la première chambre, avec la seconde chambre éventuelle, avec aucune chambre, ou avec les deux chambres. Dans un mode de réalisation, la première chambre comprend un lit d'échange d'ions et la seconde chambre comprend au moins un agent de nettoyage.
