Description

 

Calcium chloride desiccant is a highly efficient hygroscopic material with calcium chloride as its main ingredient. It is often used to control and reduce humidity in closed environments. Calcium chloride is able to effectively remove moisture from the air due to its strong hygroscopic and water-absorbing properties. It forms a gel-like substance after absorbing moisture, thereby preventing the re-release of moisture. This product is commonly used in a variety of fields such as food packaging, pharmaceuticals, clothing, electronic products and shipping containers to help protect products from moisture damage.

 

Performance

 

Calcium chloride desiccant has excellent moisture absorption performance, which is reflected in its excellent moisture absorption rate and capacity. In general, this product can absorb moisture up to 250% of its own weight. This means that it can quickly absorb moisture from the air in an environment with high relative humidity. For example, at a relative humidity of 90%, this product can reach its maximum moisture absorption within a few hours. In addition, its moisture absorption capacity is also very outstanding. It can continue to absorb moisture for a long time. Therefore, it is an ideal choice for long-term moisture protection needs. Such performance makes this product stand out in applications that require high moisture absorption efficiency.

 

Compared With Silica Gel

 

1. When the relative humidity exceeds 70%, its moisture absorption effect is significantly better than that of silica gel. It can absorb up to 250% of its own weight in moisture, while the moisture absorption rate of silica gel is usually only 20-30%. For example, at 90% relative humidity, the calcium chloride type can quickly reach its maximum moisture absorption capacity.

2. This product has a larger moisture absorption capacity. It is suitable for environments that need to maintain low humidity for a long time. For long-term storage items, such as large equipment, textiles and food, this product can continuously and effectively absorb moisture to prevent moisture damage.

3. In long-distance transportation, especially cross-sea transportation, the goods are easily exposed to high humidity conditions. Calcium chloride desiccant can more effectively prevent the goods from getting damp. During transportation for more than 15 days, this product remains efficient effect, while the moisture absorption efficiency of silica gel gradually decreases.

 

Therefore, it is more effective to give priority to this product when facing high humidity, long-term moisture protection and moisture protection during transportation.

 

FAQ

 

Q1: How to store this calcium chloride desiccant?

This product should be stored in a dry, cool environment. Avoid contact with moisture. It should be sealed well to avoid long-term exposure to air and failure before moisture absorption.

 

Q2. How to dispose of this product after use?

The used product should be handled in accordance with local regulations. It can be placed in a plastic bag and sealed, and then disposed of as ordinary waste. However, direct discharge into the sewer or natural environment should be avoided.
