Abstract
Disclosed is a photoreactive noxious substance purging agent comprising a photoreactive semiconductor, a carrier, and a microfibrillated microfiber. In this photoreactive noxious substance purging agent, loss of the photoreaction effective surface of the photoreactive semiconductor can be held down to the minimum and a sufficient noxious substance removing characteristics can be exhibited.
Claims19
A photoreactive noxious substance purging agent comprising a photoreactive semiconductor, a carrier, and a microfibrillated microfiber, wherein the weight ratio of the photoreactive semiconductor to the carrier is about 1:30 to 10:1.
A photoreactive noxious substance purging material made by coating an aqueous liquid of a composite flocculate containing at least a photoreactive semiconductor, a carrier, and a microfibrillated micro-fiber on a support comprising at least a thermoplastic resin, wherein the weight ratio of the photoreactive semiconductor to the carrier in the material is about 1:30 to 10:1.
A photoreactive noxious substance purging material made by mixing an aqueous liquid of a composite flocculate containing at least a photoreactive semiconductor, a carrier, and a microfibrillated micro-fiber, with a thermoplastic resin fiber dispersion and making the mixture into a sheet by a wet paper making process, wherein the weight ratio of the photoreactive semiconductor to the carrier in the material is about 1:30 to 10:1.
A photoreactive noxious substance purging material made by mixing an aqueous Liquid of a composite flocculate containing at least a photoreactive semiconductor, a carrier, and a microfibrillated micro-fiber, with an aqueous dispersion containing at least one of an inorganic fiber and an aramid fiber, making the mixture into a wet paper by a wet paper making process, laminating at least two of the wet papers, and heating and pressing the laminate to integrate them, wherein the material the weight ratio of the photoreactive semiconductor to the carrier is about 1:30 to 10:1.
