At present, a large number of ocean-going cargoes are transported in the market, and they will be transported by economical ocean containers. However, the containers are in a sealed state, and the temperature difference between the inside and outside is large. The temperature difference between day and night is more obvious during shipping. It is necessary to remove the water vapor, and the natural container desiccant is produced. Materials currently used to produce container desiccants: calcium chloride, montmorillonite, minerals, etc., which can be divided into calcium chloride desiccant, montmorillonite desiccant, and mineral desiccant according to the difference of production materials. With the development of science and technology , container desiccant has been widely used by enterprises, and it is especially important. However, enterprises have higher and higher requirements for desiccant, especially in terms of adsorption capacity, so how to choose container desiccant?

The ability to continuously absorb moisture for a long time

The container is not a completely closed space. During the shipping process, it is constantly exchanged with the outside air, and the outside water vapor will continuously enter the container. At the same time, the shipping time of the container can be as long as 40-60 days, so the container desiccant can absorb moisture continuously for two months or even longer, which can effectively reduce the humidity of the air in the container.

Adapt to higher temperature differences

In extreme cases, it may experience temperatures as high as 70-80°C and as low as -10 to -20°C during the shipping process. It is required that the container desiccant can maintain the moisture absorption capacity at these temperatures, and has the effect of reducing the air humidity in the container. The container has a large space, and is not completely sealed.The temperature difference between day and night often reaches 50-60 °C during the shipping process. Therefore, it is required that the container desiccant to absorb moisture quickly and a lot, sensitively reduce the humidity of the air in the container, and then ensure that no condensation occurs when the temperature drops sharply. Under the condition of temperature of 25℃ and relative humidity of 95%, calcium chloride desiccant can absorb moisture up to 200%-300%, which is more than 8-10 times of mineral desiccant and silica gel desiccant.

Safe and reliable, no leakage risk

Calcium chloride desiccant adopts double-layer leak-proof packaging, non-woven fabric + DuPont paper double layer, one-way breathable and moisturizing, and condensed into a solid gel after moisture absorption, which firmly locks the moisture and dries into a solid state.

Meet environmental protection requirements

Now the European Union, the United States and even the whole world pay more and more attention to the environmental protection requirements of imported goods. The desiccant as a packaging accessory must meet the environmental protection requirements in order to meet the needs of export goods,such as complying with ROHS and REACH requirements, not containing DMF, disposed of as general waste.
