Document Type and Number:
Japanese Patent JP2667331
Kind Code:
B2
Abstract:
PURPOSE:To sufficiently develop catalytic action by a method wherein a fine powder of a photocatalyst is bonded to the surface of the binder layer formed on the surface of a plate member so as to be exposed from the binder layer and the binder layer is melted under heating before solidified under cooling. CONSTITUTION:A glaze layer 2 is applied to the surface of a tile material constituting a wall surface, a floor surface or a ceiling surface and a fine powder 3 of anatase type TiO2 is sprayed to the surface of the glaze layer 2 in a sol form as a fine powder of a photocatalyst using a sprayer and the glaze layer 2 is melted under heating before cooled to be solidified. Since this TiO2 sol is sprayed to the surface of the glaze layer 2 so as not to be perfectly embedded in the glaze layer 2, a part of the TiO2 fine powder 3 enters the glaze layer 2 and the other part thereof is held to an exposed state. As a result, the exposed part of the TiO2 fine powder can be directly irradiated with ultraviolet rays and adsorbed water reacts with the hole of the photocatalyst to form a hydroxyl free radical OH* which, in turn, reacts with ammonia to deodorize ammonia.
