Both buffered silica gel and saturated salt solutions can be used to regulate relative humidity in display cases, but these two methods for climate control work on entirely different principles.

Estimating the Amount of Silica Gel Buffer Needed The display case buffer should not need servicing more than once a year. In a northern temperature climate, within a non- humidified building

With all humidity buffering systems, we are confronted with the problem of moving the conditioned air to the artifacts on display. The saturated salt solution will actually maintain the RH perfectly only within the tub.

Blue indicating silica gel is impregnated with cobalt chloride which changes from blue to pink as the desiccant becomes saturated. This visually warns inspectors of the need for replacement.

As with non-indicating silica gel it is a granular, porous form of silica made synthetically from sodium silicate and a mineral acid. This produces an amorphous micro-porous structure with a distribution of pore opening sizes of roughly 3-60

As the surface tension of silicone compounds is very small, therefore easily amino silicone micro emulsion spread on the fiber surface to form a good smooth feel. In general, the smaller the value of ammonia, amino silicone oil molecular weight is
