Abstract:
A flexibilizer, the composing of polyethylene glycol 600,aqueous epoxy (B-63) and hydroxyethyl cellulose, used to restore huge historic photos with curl and fold has been investigated. The mechanism on the action of the flexibilizer in the restoration was studied by using polarization microscope, scanning electron microscopy, X-ray diffractometer, thermogravimetric analysis and differential scanning calorimetry. The results indicate that the performances including flexibility, folding strength, tensile strength, tearing strength and chromatic aberration for the restored photos are improved. This flexibilizer possesses important application value in restoration of curled huge historic photos.
