Silica gel desiccant beads is a highly useful variety of desiccant, available in a range of mesh sizes to meet the needs of its many possible uses in industry. It does not react with chemicals, and is tasteless, odorless, non-toxic, and non-corrosive. It is extremely porous and can adsorb a large amount of water due to its vast amount of internal surface area. Since it is non-deliquescent, its size and shape always remain the same, and there are no chemical reactions or byproducts that result from the adsorption process. Even when saturated with water, the gel stays free-flowing, and dry. What makes blue indicating silica gel particularly useful is that, as it adsorbs water, it changes color, going from blue to purple to pink as the moisture is adsorbed.
Use:
1. Used for absorbing moisture of instruments, gauges and equipment in the enclosed conditions.
2. After adsorb moisture, it turns blue into red, visually indicating the relative humidity of the given environment..
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment.
4. Used to judge if the humidity of a environment is up to the specified requirements and to determine if the adsorbent or drier ceases to be effective.
