摘要:
A photocatalytic titanium dioxide coating composition is described, which comprises (a) finely-divided titanium dioxide particles exhibiting photocatalytic activity, (b) particles of an inorganic compound other than titanium dioxide, or particles of an organic compound convertible to particles of an inorganic compound on firing, (c) a binder, and (d) a solvent. The articles of an inorganic compound have an average particle diameter larger than that of the finely divided titanium dioxide particles and falls within the range of about 0.1 &mgr;m to about 1.0 &mgr;m. The inorganic compound particles are substantially insoluble in the solvent. The amount of the inorganic compound particles is in the range of about 0.5% to about 7% by weight based on the weight of the finely divided titanium dioxide particles. By coating a surface of a substrate with the coating composition, a coating film exhibiting excellent photocatalytic activity and no interference color is formed.
摘要:
A food container on which surface titanium oxide particles are fixed, where titanium oxide particles may contain brookite crystals, the material of which the food container is constructed may be stainless steel, and the titanium oxide particles may be bonded using a sintering aid, a binder or both. When the food container is made of glass, satisfactory mechanical strength of the container can be maintained even when the thickness of a wall of the container is reduced. Since titanium oxide particles can be fixed onto a surface of a food container at a temperature as low as 20 to 450° C. by use of a sintering aid, a binder or both thermal deformation of glass forming the food container can be prevented.
摘要:
An object of the present invention is to provide a transparent noise-barrier wall which is slow to foul, easy to clean even when fouled, and capable of maintaining these effects over a long period of time. The transparent noise-barrier wall has brookite titanium dioxide substantially existing on the surface. The titanium dioxide particles preferably contain about 20% by mass or more of brookite titanium dioxide.
