の環境汚染の大きな要因となる。Since the photocatalytic reaction is caused by irradiation of ultraviolet light or visible light, it is possible to use sunlight rays. However, when the sunlight rays are mainly used, the weather is irregular. In such cases, the photocatalytic reaction efficiency tends to decrease. To increase the efficiency of photocatalytic reaction,
It is necessary to form a photocatalytic reaction film on the entire surface of the structural material to be processed, together with a technique for securing a light source and the like. However, in Technical Examples 1 to 11, it cannot be said that the technology for efficiently forming a photocatalytic reaction film on a wide range of surfaces to be treated is provided. In addition, in the method using an organic tin-based paint, although it can be applied relatively easily to a wide range of surfaces to be treated, heavy metals such as organic tin are highly toxic to living organisms and decompose naturally. Since it has difficult characteristics, it is a major factor of environmental pollution such as flowing out to the ocean and accumulating in sediment.

シでこすり落とす技術が採用される。When a photocatalytic reaction film is formed on a surface of a structural material to be processed, a soft layer is arranged on the surface to be processed, and photocatalyst particles are interposed on the soft layer. A technique is employed in which a part of the photocatalyst particles is cut into the soft layer. The soft layer is formed by applying an adhesive or a pressure-sensitive adhesive to the surface to be treated. As a technique to fix the photocatalyst particles, spray the photocatalyst particles on the soft layer,
A technique of forming a photocatalytic reaction film in a state in which photocatalytic particles are bitten into a soft layer by kinetic energy is employed. In forming the photocatalytic reaction film, a technique is also employed in which, after spraying the photocatalyst particles, excess photocatalyst particles are dropped to leave the remaining photocatalyst particles exposed. When forming the photocatalytic reaction film, if the photocatalyst particles are carried in a state where the soft layer on the surface to be treated is bitten, the photocatalyst is carried on the entire soft layer. When the surface to be treated is softened by heating or the like, the surface to be treated itself becomes a soft layer. In addition to the application, a room temperature-curable adhesive or a pressure-sensitive adhesive is applied, and the photocatalyst particles are supported and cured. The photocatalyst particles are put on a gas flow such as air and blown into the surface,
For example, a technique of pressing a part of the photocatalyst particles into the soft layer by pressing with a roller is also employed. As a technique for removing excess photocatalyst particles, a technique for scraping off with a scraper or the like or a technique for scraping off with a brush is used.
