CLEANING AGENT

摘要

Cleaning agent contains a component comprising one or more of titanium oxide, titanium oxynitride (both with less oxygen than titania), diamond-like carbon and titanium oxide-silica complex, which may be partly covered by ceramic; viscosifier; and oxidizing agent. Cleaning agent contains a component comprising one of more of titanium oxide (TiO x), titanium oxynitride (TiO yN 2 - y), diamond-like carbon and/or titania silica complex TiO zSiO 2, optionally partly covered by ceramic; thickener; and oxidizing agent. x : more than 1.5 to less than 2; y : more than 1 to less than 2; z : 1.5-2. Independent claims are also included for the following: (1) a cleaning method which comprises coating an article for cleaning with the cleaner, and exposing it to light; (2) an antibacterial material or antibacterial product containing TiO x, TiO yN 2 - y, diamond-like carbon and/or titania silica complex TiO zSiO 2, or metal ion doped titanium oxide, whose surface is partly coated with optically inert ceramics; (3) a cleaning liquid containing the antibacterial material of (2); (4) a method of making an environmental material by supporting porous calcium phosphate on the surface of a material by immersing a substrate with a titanium oxide surface in an aqueous liquid containing calcium ion, phosphate ion and/or hydrogen phosphate ion, and irradiating with microwaves; (5) an environment purification product which includes the material of (4); (6) a functional absorbent where titania particles partly coated with optically inert ceramic are supported in a porous material; (7) manufacture of the functional absorbent by dispersing titania particles partly coated with optically inert ceramic in solvent, coating on a porous material and drying; and (8) environment purifying product containing the absorbent of (6).
