The definition of desiccant is a substance that has hygroscopic properties. It is a drying agent, and it will remove moisture from the air. Desiccants are often packaged with moisture-sensitive products to make sure they have a dry atmosphere.
The desiccator is an laboratory glassware used to maintain a sample far from influences of the atmosphere and if possible at a constant temperature. The ab(d) sorbed water is eliminated from the sample.
See the link below for an example.

Although technically they are different situations, for most practical purposes these two terms cover the point at which a desiccant no longer adsorbs moisture. Saturation is when the desiccant is full and even if there were moisture molecules to pick up, the desiccant could not do it. Equilibrium capacity is when the desiccant has pulled so much moisture out of the air that the air retains a stronger hold on the moisture molecules than the desiccant can exert. At equilibrium capacity, adding more desiccant will not bring the Relative humidity any lower.
The iron would not rust, because calcium chloride is a desiccant. For rusting to occur there are two vital components: water and oxygen. Since calcium chloride is a desiccant, it would absorb the water, so rusting would not occur.
The name of P2O5 is phosphorus pentoxide. It is a white solid that is used as a desiccant and dehydrating agent..
Phosphorus is used as a drying agent to be used with materials that do not react. It is passed through the reaction at a particular temperature. It is a white crystalline solid and serves as a powerful desiccant.
It is used as a desiccant. However, because of the dangers inherent to perchlorates, this is not a wise use of it. It is a very powerful oxidant and may cause fire or explosion if used to dry come gasses.
What if your child swallowed desiccant. What can you do
To desiccate means to dry out. A desiccant absorbs water.
No. A desiccant is something that absorbs water.
Dehumidifiers absorb moisture from the air into desiccant materials like Silica gel . The air to be dried, or processed, is ducted through the rotor in one air stream.
Aluminium Oxide powder and Sodium Silicate Powder makes Desiccant.
Desiccant Packs are use to control moisture, humidity, mold and mildew. These Desiccant Packs are USFDA Arpprove and fill with Silica gel, Molecular Sieve, Activated Clay and Carbon.

One method would be to weigh a desiccant and then expose it to your known target volume to allow it to dry the material. Then re-weigh the desiccant. If your'e looking at a low % of water vapour, you should attempt to minimise the 'tare weight' of your desiccant. Crumbled calcium sulphate is a safe desiccant - just dry it out well beforehand.
I'm not familiar with pneumatic control systems, but a desiccant dries the air by absorbing water. How about this for an answer:The air used in a pneumatic control system may pass through a desiccant to ensure that it's dry.
Desiccant bags are filled with a grain that will help absorb moisture from the air or can be used in containers for low moisture levels. It is helpful in protecting food, clothing and machines.
The color the indicator needs to be depends on what it was when the desiccant was fresh. If the indicator color was blue, then it will turn pink when saturated with moisture. If the indicator was orange, then it will turn green as it absorbs moisture. So, the desiccant cartridge will need to be replaced if the indicator is either pink or green. FYI: The desiccant indicators that turn blue to pink contain cobalt chloride, which is toxic. The orange to green alternative is non-toxic. Source: http:www.silicagelpackets.com
