METHOD FOR SPEED-UP DETERMINATION OF ACIDITY OF TRIACETATE-CELLULOSE BASIS OF MOVIE-PHOTOGRAPH DOCUMENTS |
| 摘要 |
A method for the determination of acidity of cellulose triacetate base of motion picture documents by means of detector tapes AGF-acetate includes placement of detector tapes AGF-acetate to the box with material that is controlled, with evaluation of change of color of the band. The tape of AGF-acetate wetted at one side with a drop of distillated water is placed by dry side downwards to open box preliminarily placed to a transparent polyethylene pack. |
