Title: Method for recycling injection-molded article for photographic sensitive material and recycled parts fur photographic sensitive material
Inventor: KAMATA KAZUO
IPC: G03C3/00
Filed: 2000-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of the photographic properties of recycled parts for a photographic sensitive material. SOLUTION: Resin parts such as the front and rear covers of a film unit with a lens and the base of the unit body are crushed, the crushed material is pelletized again and the resulting regenerated resin pellets are injection-molded as part of starting materials and used as recycled parts. When the crushed material is melted by heating in injection molding, the thermoplastic resin deteriorates or degenerates thermally and the performance and quality of recycled parts lower as compared with those of new parts. When the thermoplastic resin deteriorates thermally, a harmful gas that causes a chemical reaction with a photographic sensitive material to adversely affect its photographic properties is produced in larger quantities. An antioxidant is added so as to prevent the thermal deterioration and carbon black is added so as to adsorb the produced harmful gas.  The carbon black and the antioxidant are added in the form of master batch resin pellets obtained by concentrating and mixing those with a thermoplastic resin.
