As a supplier of calcium chloride desiccant, I often get asked whether this type of desiccant can be used in shipping containers. It’s a valid question, considering the unique environment and challenges that shipping containers present. In this blog post, I’ll delve into the details of using calcium chloride desiccant in shipping containers, exploring its effectiveness, advantages, and potential considerations. Calcium Chloride Desiccant
Understanding the Problem in Shipping Containers
Shipping containers are used to transport a wide variety of goods across the globe. During transit, these containers are exposed to different environmental conditions, including changes in temperature and humidity. One of the most significant issues faced in shipping is the formation of condensation inside the container. When warm, moist air comes into contact with the cooler surfaces of the container walls, it can lead to the formation of water droplets. This phenomenon, known as container rain, can cause significant damage to the goods being transported.
Moisture can lead to a range of problems, such as mold growth, rusting of metal products, and degradation of paper and textile goods. In some cases, the damage can be so severe that the goods become unsellable. Therefore, it’s crucial to find an effective way to control the humidity inside shipping containers.
How Calcium Chloride Desiccant Works
Calcium chloride desiccant is a highly effective moisture absorber. It works by attracting and trapping water vapor from the surrounding air through a process called hygroscopy. Calcium chloride has a strong affinity for water molecules, and when it comes into contact with moisture in the air, it forms a brine solution. This process continues until the desiccant is saturated with water.
One of the key advantages of calcium chloride desiccant is its high absorption capacity. It can absorb up to 300% of its own weight in water, making it one of the most efficient desiccants available. This high absorption capacity means that a relatively small amount of calcium chloride desiccant can effectively control the humidity in a large shipping container.
Advantages of Using Calcium Chloride Desiccant in Shipping Containers
1. High Absorption Capacity
As mentioned earlier, calcium chloride desiccant has a very high absorption capacity. This is particularly important in shipping containers, where large volumes of air need to be dehumidified. A single calcium chloride desiccant unit can absorb a significant amount of moisture, reducing the risk of container rain and protecting the goods inside.
2. Wide Temperature Range
Calcium chloride desiccant can work effectively in a wide range of temperatures. Shipping containers can experience extreme temperature variations during transit, from hot and humid conditions in tropical regions to cold temperatures in colder climates. Calcium chloride desiccant can maintain its moisture absorption properties across these different temperature ranges, ensuring consistent protection for the goods.
3. Long – lasting Effectiveness
Calcium chloride desiccant has a relatively long lifespan. Once it is placed inside a shipping container, it can continue to absorb moisture for an extended period. This means that it can provide continuous protection throughout the entire shipping journey, which can take weeks or even months depending on the destination.
4. Cost – effective
Compared to some other desiccant options, calcium chloride desiccant is relatively cost – effective. Its high absorption capacity means that less desiccant is required to achieve the same level of moisture control. This can result in cost savings for shippers, especially when transporting large volumes of goods.
Considerations When Using Calcium Chloride Desiccant in Shipping Containers
1. Packaging
The packaging of the calcium chloride desiccant is crucial. It should be designed to prevent the leakage of the brine solution formed during the moisture absorption process. Specialized packaging materials, such as breathable non – woven fabrics, are often used to ensure that the desiccant can absorb moisture while keeping the brine contained.
2. Placement
Proper placement of the desiccant inside the shipping container is essential for optimal performance. It should be placed in areas where moisture is most likely to accumulate, such as near the container walls and in the corners. Additionally, the desiccant should be evenly distributed throughout the container to ensure that all areas are effectively dehumidified.
3. Compatibility with Goods
It’s important to consider the compatibility of the calcium chloride desiccant with the goods being transported. While calcium chloride is generally safe for most goods, some sensitive materials may be affected by the desiccant. For example, certain electronic components may be damaged if they come into contact with the brine solution. In such cases, it’s necessary to take additional precautions or choose a different desiccant.
Real – world Applications and Case Studies
Many shippers have successfully used calcium chloride desiccant to protect their goods during transit. For example, a company that ships wooden furniture overseas found that using calcium chloride desiccant significantly reduced the incidence of mold growth on the furniture. The desiccant was placed in the shipping containers, and after a long – distance journey, the furniture arrived in excellent condition.
Another case involved a company that transports metal products. By using calcium chloride desiccant, they were able to prevent rusting of the metal parts, which saved them from significant losses due to damaged goods. These real – world examples demonstrate the effectiveness of calcium chloride desiccant in protecting goods in shipping containers.
Conclusion
In conclusion, calcium chloride desiccant can be an excellent choice for use in shipping containers. Its high absorption capacity, wide temperature range, long – lasting effectiveness, and cost – effectiveness make it a reliable solution for controlling humidity and preventing damage to goods during transit. However, it’s important to consider factors such as packaging, placement, and compatibility with the goods.
