What does the term Desiccant mean?
Desiccation refers to the state of extreme dryness, or the process of extreme drying. A desiccant is a substance that absorbs or adsorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. Silica gel, calcium sulfate, montmorillonite clay, and molecular sieves are commonly used as desiccants.
Desiccants are also used to dry solvents, typically used for moisture free reactions. While different desiccants are used differently, the general method involves stirring the solvent to be dried with the drying agent.
Usually, the drying agent will react with moisture to form a solid insoluble in the solvent being purified. It can be removed simply by filtering. For more demanding applications, requiring very pure, air-free and/or moisture free solvents, a distillation still used with a desiccant able to remove air, moisture, and other impurities all at once.
Why you need Desiccant Moisture Protection
The root cause of moisture damage in container transport is the simple fact that warm air can hold more moisture than cold air. Take the dewy grass in the morning after a cool summer night as an example. Moisture gets into the air in the container from the outside or by evaporation from the cargo. When the temperature in the container changes damaging moisture conditions arise. The only remedy is to keep the air inside the container dry. Desiccants (substances that remove moisture from the air) control the moisture level in containers, crates, boxes and so on.
