A collection apparatus for storing prolate photos belongs to the technical field of cultural relic protection equipment and includes multiple drawable arched drawing-type plates disposed in the cabinet, which enables the prolate photos to be fully flattened without repeated and memory curling. At the same time, a magnetic plating board is embedded in the bottom of every arched drawing-type plate, and a plurality of soft magnetic strips are placed on the surface of every arched drawing-type plate, and the magnetic attraction is formed between the magnetic plating board and the soft magnetic strip for fixing the prolate photos. As a result, the collection apparatus is reasonable in design and convenient to use, and is able to durably and stably protect prolate historical photos.

Collection apparatus for storing prolate photos

A separating device and method for a bonded cine film, belonging to the field of image file protection and repair technologies. The separating device comprises a pressurizing device, a separating device and a liquid nitrogen storage device. The pressurizing device is connected to the liquid nitrogen storage device; the liquid nitrogen storage device is connected to the separating device for providing liquid nitrogen thereto; the separating device comprises a film receiving chamber for accommodating a film to be separated; the pressurizing device pressurizes the liquid nitrogen storage device allowing liquid nitrogen to enter the film receiving chamber. Due to a difference between expansion coefficients of a base layer and emulsion layer of the film under low temperature, micro-pores and gaps may be generated in the base layer and the emulsion layer of a bonded film roll; the liquid nitrogen penetrates into the micro-pores and gaps of the bonded film.
