Nano-antibacterial deodorant for removing harmful gases by spraying the material, chemically bonded to the hydrophilic group of the titanium compound (material) coating the surface of the irregularity of the group (OH), while spraying the phosphoric acid compound of titanium dioxide, due to the evaporation of water, the formation of a (non-crystalline body shafts is 0.05um? 0.5um thick) very strong adsorption of inorganic porous polymeric film, after drying, having a nano-sized micropores formed, is effective antifouling pro water-based surface. Strong adsorption, has the potential transfer function, the effective ionization decomposition organics adsorbed. High ion conductivity, since the role of preventing electrostatic effect repel dirt, surface film between the soil and the soil moisture permeation material capable of lifting, the effect of washing dirty easily.
