What is the function of container desiccant? Why some customer require to use desiccant inside container? Many people know desiccant from it is used in household for moistureproof.Such as desiccant used in wardrobes and shoe cabinets.For the container desiccant been used in shipping is unfamiliar for most of people. In fact, with the rapid development of international economy and trade, and most of cargo from all over the world are loaded by containers and shipping by sea. So container desiccant is designed to solve the problem that the cargo moldy and wet during transportation..
During ocean transportation, containers will cross different latitudes and climate region, and the high temperature and high humidity climate change. Due to the day time and night time，the temperature change will be between 0 ℃ - 80 ℃, and the humidity will be as high as 98%. When the temperature is 30 ° C, the water content in the air is 30.4g / m3. When the temperature is reduced from 30 ° C to 18 ° C, the water vapor content will drop to 15.4 g / m3. The huge temperature difference between day and night in the sea causes the high temperature air rich in water vapor that is locked in the container during the day to become super-saturated at night due to the decrease in temperature. The water vapor condenses into water, which is called condensation phenomenon,In other words, it's called container rain.It will cause to negative effect on the packaging image of the cargo，so we need to put the container dry pole to solve this problem.Container dry pole it is mainly used in sea containers to absorb the water vapor produced during the ocean transportation or storage, so as to reduce the moisture content inside containers and ensure the cargo are transported in the best condition.
When domestic cargo are exported abroad,foreign buyers always require the container dry pole to be hung inside container for necessary moisture-proof and dehumidification, because this can not only avoid the loss of cargo’s moisture, but also avoid all unnecessary disputes caused by cargo's moisture.
