摄影材料恶化变质的原因影响摄影材料保存有许多因素,环境条件是这些因素中的最重要的因素,它包括温度、相对湿度、空气中的污染杂质和生物学上的媒介物。温度和相对湿度是互相依存的,在无控制的情况下,相对湿度随温度的下降而提高。高温达大约80°F,高湿相对湿度达大约60%,将加速有害的化学反应。高湿也会促使明胶、感光乳胶变软,使它们粘在其它物质的表面,同时也将促使霉菌生长。因为许多化学反应都离不开温度和水,在高温高湿的情况下化学过程的残留物的变质影响是比较大
Photographic materials cause deterioration Deterioration of photographic materials stored many factors, environmental conditions are the most important of these factors, including temperature, relative humidity, air pollution impurities and biological media. Temperature and relative humidity are interdependent and, under uncontrolled conditions, the relative humidity increases with decreasing temperature. High temperatures up to about 80 ° F, high humidity relative humidity of about 60%, will accelerate the harmful chemical reactions. High humidity can also cause the gelatin, the emulsion becomes soft, make them stick to the surface of other substances, but also will promote mold growth. Because many chemical reactions are inseparable from temperature and water, the deterioration of chemical residue in the case of high temperature and high humidity is relatively large
