Note that the absolute amount of moisture in saturated air increases exponentially with increasing temperature. During airlift, it can take in as much as 0. The higher the valve pressure and vacuum reseal settings, the less often the valve will breathe. For this to be an advantage, however, the enclosure must be structurally strong enough to withstand the pressure and vacuum differentials imposed by the valve.
Common permeable materials are most seals and seal materials, plastics and other intentionally porous materials. Permeation constitutes a small amount of moisture but over time it can, and will, build up to levels high enough to cause a problem on the inside of the enclosure.
Desiccators also known as dehydrators or dehumidifiers are packages to hold desiccant which function as self-contained moisture control systems. They hold the desiccant to protect the contents of enclosures from moisture damage and are used in a wide variety of aerospace and electronic applications. There are two basic types of desiccators: dynamic and static.
Dynamic Desiccators allow a moist gas stream to flow through the desiccant bed to dry the gas. More complicated types of dynamic desiccators are self-regenerating, usually large and expensive, and require an external power source.
Static Desiccators , on the other hand, can vary in size from tiny packets or capsules to gallon drum-sized canisters and larger, filled with desiccant. They are generally much less expensive, but require periodic re-generation or replacement. The ones shown on this website demonstrate the wide variety of shapes and sizes and manufacturing technologies that are used to fit the required application. They are available in both standard and custom configurations, made from various materials and can be supplied with any of the three principal commonly commercially available desiccants: silica gel, molecular sieve or bagged clay used with TA and TA desiccant holders and baskets.
The amount and shape of space available for the desiccator. The level of moisture protection required. The ambient moisture and temperature levels. The length of time desired before recharging. The anticipated leakage rate of the enclosure. Dusting protection required, if any. Any unusual environmental conditions. Because both silica gel and molecular sieve react rapidly to moisture, they must be handled under controlled minimum humidity conditions to retain maximum adsorption capacity.
At AGM, all desiccators are filled in a dry box, and packaged in materials with extremely low water vapor transmission rates. In addition, they should establish procedures that will minimize the time between removal of the product from its package and its installation in the sealed enclosure.
Desiccants are a vital component of packaging, shipping and storing products. It helps prevent the growth of mould, mildew and other bacteria on items such as clothing and food.
As well as prevents the corrosion and degradation of items such as metal and electronic components. It is important to find the desiccant that is best suited for your product and needs.

They have the ability to absorb and retain moisture inside of themselves, making the air in the product packaging contain a desiccant that achieves the desired moisture to ensure safe, Degreasers are produced in the form of granules such as: Silica Gel, Activated Clay, Activated Alumina, Very few people know what a desiccant is because they rarely come in contact with them.
Absolute humidity is a measure of water vapor moisture in the air, without any relation to the temperature. Relative Humidity is also a measure of water vapour, but it is relative to temperature. It is expressed as the amount of water vapor in the air. It is the amount of water vapor as the percentage of the total amount that could be held at the current temperature. A high or low level of relative humidity within an enclosed container can damage the integrity of the package.
It can also affect the hygiene of the product. In the case of electronics devices, it can damage crucial parts of the device, which can corrupt its functioning. Relative Humidity is a factor that can cause many problems to the enclosed packages. Desiccants serve to eliminate the humidity from the air, and they absorb the excess moisture. Moisture can create an environment in which bacteria, mold, and fungus can grow.
It can degrade the quality grade of your package. These desiccants are usually used in packages where products can be dissolved or can be otherwise compromised by the moisture and humidity. For, eg. In windows or soundproof glasses, there is an insulating material placed between two glasses. It can allow moisture to enter and can compromise the visibility of the glass pane.
You need to determine if your product can get compromised or if the integrity of the product can be compromised due to the effect of relative humidity. There are many products that can get affected due to humidity. It can be food, cosmetics, clothing, electronics, computer equipment, military-grade equipment, and many more.
There are various types of desiccants, and they are varied accordingly. Every desiccant material has some different qualities which make them unique.
Activated Alumina can be used to absorb the catalyst in polyethylene production and hydrogen peroxide production. It can also be used as a selective adsorbent to remove chemicals like arsenic, fluoride, and sulfur from gas streams. An excellent absorbent, activated carbon is a highly porous substance for the purification of water, air, and gases as well as for odor control. Activated clay is one of the natural elements used to control the relative humidity level of the environment.
