Silica Gel Air Conditioning for Film Processing

E. C. Holden

The need of properly conditioning air in motion picture film processing plants is pointed out and the values of temperature and relative humidity in current use in such plants are indicated. In particular, the process of humidifying, in which pure silica which has passed through the sol and gel stages of manufacture, commonly called silica gel, is used, is described. The principles involved in the process and the efficiency of the method in controlling the condition of air are explained, and curves are given showing the efficiency of adsorption.
