静电斑纹是指在显影后的底片上,出现像照片那样的树枝状斑纹和中心密度大并向四周扩散的圆形斑点斑纹,它们往往作为一种灰雾密度出现。由于某种原因带有静电荷的胶片,如果与带有相反静电荷的物体接触时放电、发光,使胶片感光产生了灰雾。静电斑纹的发生,决定于引起胶片的带电与放电的机会,根据摩擦带静电的物质的带电分类,静电的电性可分为正电和负电,对于胶片就产生了带正电荷和带负电荷二种静电斑纹。出现上述的树枝状斑纹,说明胶
Electrostatic streaking refers to the appearance of dendritic markings such as photographs on a developed backsheet and round speckles that have a large center density and spread around, and often appear as a kind of fog density. For some reason, films with electrostatic charge discharge and emit light when exposed to objects with opposite electrostatic charges, causing the film to become foggy. The occurrence of electrostatic streaks is determined by the chances of charging and discharging of the film. According to the charged classification of a substance with a triboelectric charge, static electricity can be divided into positive and negative charges, and positive and negative charges are generated for the film Two kinds of electrostatic markings. The above dendritic markings appear, indicating that the glue
