Description
In this type all the particles of Silica Gel are not impregnated with any Kind of indicators. When free from moisture the particles are transperent white. As they are put to use, the particles take up moisture, Silica Gel gradually turns little milk or hazzy in whiteness, these Silica gel always has higher capacity for Moisture uptake than any indicator type Silica gel.These can be regenerated in dryers or inside dehumidifiers.
Silica gel is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules ( having the appearance of crystals) or hard regular beads. A microporous structure of interlocking cavities gives a very high surface area (800 square meters per gram). It is this structure that makes silica gel a high capacity desiccant. Water molecules adhere to the gels surface because it exhibits a lower vapour pressure than the surrounding air. When an equilibrium of equal pressure is reached,no more adsorption occurs. Thus the higher the humidity of the surrounding air, the greater the amount of water that is adsorbed before equilibrium is reached. It is in these higher humidity conditions (above 50% Relative Humidity) that stored or in-transit items are susceptible to damage.The beauty of silica gel is the physical adsorption of water vapour into its internal pores. There is no chemical reaction, no by products or side effects. Even when saturated with water vapour, silica gel still has the appearance of a dry product, its shape unchanged.Silica gel is one of the oldest and most popular desiccant and adsorbent used for a wide number of industrial and consumer applications.
