FAQ

Desiccants can bind water or gases physically or chemically. Physical binding is by adsorption, chemical binding is by absorption. In adsorption, solid desiccants such as silica gel (silicagel), bentonite and molecular sieve bind water from the atmosphere.

The packaging materials used for the desiccant bags, for example TYVEK, are breathable and thus permeable to water vapor.

The most commonly used desiccants are drying agents that physically absorb moisture, i.e. adsorb it.

For example:

• Silica gel
• Bentonit clay
• Molecular sieve

Physically acting desiccants are regenerable by temperature, but are most often inefficient due to high energy costs.

In the physically acting desiccant, moisture is released at high temperatures.

In PE bags, desiccant products have a shelf life of about 6-10 months. With other types of packaging, the shelf life of desiccant products can be extended up to 24 months.

The amount of oxyacetylene required depends on many factors.

These are for example: environmental conditions, packaging materials, packaging type, etc. Our staff will be happy to assist you to correctly determine the required quantity. You can reach us here.

Desiccants are used where humidity is present and condensation can occur, especially when temperatures fluctuate.

There are numerous applications for desiccants, such as overseas shipping containers, electronic parts, computers, collections such as coins, stamps, model trains and more.

Desiccants are also used in the pharmaceutical and healthcare industries, as well as in metal parts, food packaging, luggage, cereals, optical equipment production, animal feed, leather goods, metal powders, libraries, antique treasure preservation and file management.

Adsorption and absorption are two different processes used to absorb substances into another substance. The difference lies in how the substances are absorbed.

In adsorption, molecules or particles adhere to the surface of another material. The adsorbing material is usually a solid that binds other substances to its surface. The adsorbed substances remain attached to the surface without fully penetrating.

For adsorption are most often used desiccants such as silica gel.

In absorption, on the other hand, a liquid or gas penetrates another liquid or solid and dissolves in it. The absorbing substance completely absorbs the molecules of the absorbed substance and integrates them into its structure. Adsorption, therefore, means adhering to the surface, while absorption means penetrating completely into another material.

Relative humidity refers to the percentage of water vapor present in the air compared to the maximum amount of water vapor that can be present in the air at a given temperature. It is a measure of how much moisture the air can hold before it becomes saturated.

For example, if the relative humidity is 50%, it means that the air contains half of the maximum amount of water vapor that can be absorbed at the current temperature. If the relative humidity is 100%, the air is saturated with as much water vapor as it can hold at the current temperature, which means that it cannot hold any more moisture.

Relative humidity depends on the air temperature, as warm air can absorb more moisture than cool air. Therefore, relative humidity can also serve as a measure of how close the air is to saturation and as an indicator of the likelihood of condensation and moisture formation in the environment.

Desiccants have the purpose of keeping the relative humidity below 50% of the maximum saturation to prevent corrosion and mold growth. However, when the temperature drops, problems can arise because the air can no longer hold the effective moisture present at lower temperatures. As a result, the relative humidity automatically increases even though the actual amount of moisture present has remained the same, which can lead to condensation.
