Definitions
- the present invention relates to a method for producing a titanium ball coated with titanium oxide. More specifically, the present invention is excellent in deodorizing, antibacterial, antifouling, and air and water purification actions, The present invention relates to a method for producing a titanium ball that can exert its action even in a place not exposed to light such as a toilet tank. Background art
- titanium dioxide has photocatalytic activity. It is known that photocatalysts have various environmental conservation effects such as deodorization, antibacterial, antifouling, air purification and water purification due to their strong oxidizing power. For this reason, titanium dioxide catalysts are used for water purification in rivers, air conditioning in public facilities such as hospitals, schools, and offices, and water and air purification treatment, and also in household kitchens, toilets, and bathrooms.
- Japanese Patent Laid-Open No. 2 0 0 3-7 1 4 4 0, Japanese Patent Laid-Open No. 2 0 0 4-5 0 1 7 4, Japanese Patent Laid-Open No. 2 0 4-6 6 3, 2 0 0 3—see 2 1 2 7 5 4).
- Titanium dioxide is generally used as a titanium ball or the like by coating titanium dioxide powder on the surface of a ceramic, metal, resin, or, in some cases, a natural mineral base material. For this reason, various methods for forming a titanium dioxide powder film on a substrate have been proposed.
- the surface of a ceramic ball is sandblasted, then subjected to primer treatment, dried, and a titanium dioxide-containing binder is applied and baked.
- a covering member having a base material and a coating layer in which granular titanium dioxide is directly fixed to the surface of the base material without a mixed binder is proposed.
- the base material is made of sheet, film, paper, fiber, thread, cloth, glass, ceramics, concrete, resin, etc.
- a specific method for attaching titanium dioxide is, for example, a spraying process in which mist-like or powdery-like titanium dioxide is sprayed onto the substrate surface, and at least one of titanium dioxide and the substrate surface is charged with static electricity.
- Adsorption process in which titanium dioxide is adsorbed to the surface of the substrate by the electrostatic attraction force, a transfer process in which a carrier with titanium dioxide attached to the surface is brought into contact with the surface of the substrate and titanium dioxide is transferred to the surface of the substrate, etc. (JP 2005-721 6 A).
- a covering member having a thickness see Japanese Patent Application Laid-Open No. 2004-224641.
- Such a covering member is formed by press-molding alumina powder into a flat plate shape, and then sintering it at a temperature of 1 373 to 1623 K. Then, the obtained porous alumina sintered body is suspended in a liquid in which fine titanium dioxide powder is suspended. It is soaked in and filled with fine powder of titanium dioxide in the voids of the sintered body, dried, and then heated to 573 to 173 K to provide titanium dioxide in an anatase type.
- a light irradiation means is required for use in the water purification device or the air purification device.
- a water purification apparatus and an air purification apparatus comprising a substrate having a photocatalytic reaction surface in contact with water or air, and a light emitting diode mainly emitting predetermined visible light and ultraviolet light having a wavelength of 360 to 400 nm.
- a light emitting diode mainly emitting predetermined visible light and ultraviolet light having a wavelength of 360 to 400 nm.
- This composite material is a new ultraviolet / visible light active catalyst, and a new type of ultraviolet 'visible light that exhibits excellent photocatalytic activity even in the visible light region. It becomes a reactive photocatalyst. And, normally, when titanium dioxide is anatase type, the theoretical value of 38 nm is shifted to around 400 nm. In the case of the rutile type, the bandgap energy is smaller than that of the anatase type, so it reacts to light around 400 nm. On the other hand, it is said that the composite material also responds to a wavelength of 500 nm or more (see Japanese Patent Laid-Open No. 2003-333445).
- the present invention has been made in view of the above circumstances.
- the object of the present invention is to provide a titanium oxide powder having sufficient deodorizing function, antibacterial function, antifouling function, air and water purification function,
- the present invention proposes a method for producing a titanium ball that can form a coating easily and reliably.
- a further object of the present invention is to propose a method for producing a titanium ball that sufficiently exhibits the above functions even in a dark place such as a toy tank.
- a method for producing a titanium ball comprising a step of color-modifying titanium dioxide powder by collision and / or rubbing, and forming a coating of the color-modified titanium oxide on the surface of the substrate.
- FIG. 1 is a schematic cross-sectional view of a titanium ball according to a first embodiment manufactured by the titanium ball manufacturing method of the present invention.
- FIG. 2 is a schematic cross-sectional view of a titanium ball according to a second embodiment manufactured by the titanium ball manufacturing method of the present invention.
- Figures 3 (a) to (c) are schematic cross-sectional views of a catching ball made of other auxiliary substances.
- FIG. 4 is a front view of a container in which the titanium ball and the auxiliary ball of the first and second embodiments are placed.
- FIG. 5 is a partial cross-sectional view of the toilet tank when the container shown in FIG. 4 is used in the toilet tank.
- FIG. 6 is a schematic view of a planetary ball mill used in manufacturing the titanium ball of the example.
- FIG. 7 is a bar graph showing the decomposition amount of inorganic nitrogen in the solution with respect to time using the titanium ball of the example.
- 'FIG. 8 is a bar graph showing the decomposition amount of total nitrogen in the solution with respect to time using the titanium ball of the example.
- Fig. 9 is a photomicrograph showing the surface layer of the titanium ball of the example magnified 1,000 times.
- FIG. 10 is a photomicrograph showing the surface layer of the titanium ball of the example magnified 10,000 times.
- the titanium ball manufacturing method of the present invention includes a step of color-modifying titanium dioxide powder by collision and Z or rubbing, as shown in FIG. 1 or 2, for example. Titanium Bonores 11 and 12 are produced by forming a color-modified titanium oxide film 23 on the surface.
- the raw material titanium dioxide powder (or particles) is not limited as long as it is conventionally used as a photocatalyst. For example, if it has photocatalytic activity, it may be an anatase type, a rutile type that reacts with visible light, or a brookite type.
- the titanium dioxide may be ordinary titanium dioxide for photocatalyst, and the raw material is white powder, preferably anatase type titanium dioxide.
- the particle diameter of the titanium dioxide powder is preferably 1 m or less, and more preferably in the range of 3 nm to 100 nm.
- the thickness of the color-modified titanium oxide coating 23 on the surface of the substrate 21 or 22 is preferably in the range of 1 to 3 ⁇ m. If the thickness is less than the above range, the catalytic effect of titaniumbonole 11 and 12 may not be sufficient. When the above range is exceeded, the catalytic effect does not increase for an increase in the amount of color-modified titanium oxide.
- other powder raw materials 32 may be blended within a range not impairing the performance of the color-modified titanium oxide (see FIG. 3 (a)).
- an auxiliary powder that generates an electromagnetic wave having a wavelength that enhances the catalytic reaction of the color-modified titanium oxide so that it can be used sufficiently even in a place where light irradiation is low.
- Electromagnetic waves are a generic term for short-wavelength areas such as gamma rays, visible light, and long-wavelength areas such as radio waves.
- minerals that generate low-dose microwaves such as those found in naturally produced phyllite Or natural zeolite, or so-called green zeolite Minerals or natural zeolites that generate infrared or far-infrared as seen in
- such zeolite or mineral 32 need not be limited to use as a powder mixed with titanium oxide powder 23 to form a film on the surfaces of base materials 21 and 22.
