PRODUCTION OF TITANIUM DIOXIDE ADDED FILAMENT THREE DIMENSIONAL VOID STRUCTURAL BODY FORMED INTO THREE DIMENSIONAL MESHLIKE STATE

摘要

PROBLEM TO BE SOLVED: To provide a molding and producing method of a filament three dimensional void structural body having titanium dioxide exposed and fixed on a filament and formed into three dimensional meshlike form by extruding a thermoplastic raw material, to which powdery titanium dioxide is added, in a melted state from plural nozzles so as to have plural filament diameters, bending on a cooling liquid surface to point-fuse to an adjacent another filament surface, cooling and solidifying and controlling the filament three dimensional void structural body formed into the three dimensional meshlike form to be cylindrical, box like or plate like, molding the filament three dimensional structural body formed into the three dimensional meshlike form and, after that, sticking the powdery titanium dioxide to the filament surface. ;SOLUTION: The filament three dimensional void structural body 3 formed into the three dimensional meshlike form having titanium dioxide in the filament or on the filament surface is placed in a water system, a water area, the atmosphere, an industrial water, a circulating water, a city water and sewage equipment, a water receiving tank or the like as a contacting material to oxidize and decompose organic materials, organic chlorine compounds by photocatalytic reaction using titanium dioxide as a catalyst. The implantation of the larva of an adhesive shellfish is obstructed and the propagation is suppressed by fixing th filament three dimensional void structural body 3, to which titanium dioxide is added, to the outer surface of a structure or the like in the sea water region.;COPYRIGHT: (C)1999,JPO
