Introduction

Microform is an important recording and illustrated material. Having legal, scientific, industrial, artistic or historical value microform necessary Be appropriate production and preservation, as far as possible to ensure that it has a long life. Life expectancy microform to LE values \u200b\u200bto represent, for example, LE-100 and LE-500, respectively, under the specified storage conditions at least by 100 years and 500 years later, the information can still be retrieved. Factors Affecting microform shelf-life of the following three categories. A) the nature of the film. Stability microform depends primarily on the physical and chemical properties of the film, only in line with GB/T 7430- 1996 prescribed security photographic film made from microform is suitable for ultra-long-term storage. Under specified conditions, with the silver - gelatin type Black and white polyester (polyethylene terephthalate) film made microform can be stored for 500 years, silver - gelatin type black and white Acetate Cellulose ester film produced microform can be stored for 100 years. b) washing of film processing. microform life also depends on the conditions of processing a film that only fully fixed, thoroughly washed with water and Suitable drying process safety base silver - gelatin type black and white film of the microform to ultra-long-term storage. ISO 18901.2010 Dui Safety Base silver - gelatin type black and white film microform different LE value specifies the maximum amount of residual thiosulfate. Movies & high temperature, high humidity, dust, fire, water, light, harmful gases, and against certain microbes such as chemicals. c) microform storage conditions Ring will reduce the life of the microform. In hot and humid conditions, the film base will be degraded, and cellulose acetate film base than the polyester sheet Base degrades faster, therefore, compared with the acetate sheet, polyester sheet microform life longer. Microform packaging such as the release of harmful Substances will shorten the life of microform. Micrographics Silver - gelatin microforms flushing and preservation
