Container dry bag

Product category:Container desiccant
Packaging:Non woven fabric
Raw material:Calcium chloride


    During the container shipment and storage, the great temperature difference between day and night made the gas-rich air temperature supersaturated, which was locked in the container during the day. the cargo usual go through the hot temperature marine like climate and big difference in temperature, which could be between 0 ℃ -80 ℃ and the humidity could be up to 98%. We call it the dew condensation phenomenon. When the temperature is 30 ℃, the water content of the air is 30.4g/m3, if the temperature from 30 ℃ to 18 ℃ lower, the water vapor content will be reduced to 15.4 g/m3. Other water vapor condenses into water, which is commonly known as "container rain". It would cause a very negative impact to the goods packing image, so, we need a certain quantity of dry pole to solve this problem.

    Using guide

    1)Container checking:
    ◆Check any damage in the container, such as container walls, top, bottom, whether there is a hole (crack ) or not.
    ◆Container doors must be closed to seal the rubber must be good.
    ◆Containers prior to loading must be dry and clean.
    2)Container flooring moist checking:
    ◆If possible, do not use the container whose wood moisture value exceeds 20%, it will increase the risk of damp. If you cannot change, than increase the using quantity of Chunwang container desiccant based on the inside water content to ensure cargo security。
    ◆Please do not use the container whose wood humidity over 25%.
    3)Seal all holes.
    4)Take out the container desiccant from the sealed plastic bag.
    5)hanging the dry pole on the hook with tape affixed to the lower end on the inner wall.
    6)keep the distance between goods and desiccant to 5-10CM, do not cover the surface of the desiccant, and let the desiccant contact with air, so as not to affect the absorption effect. The volume of the desiccant will be increased after absorption, therefore requires appropriated space. Do not put anything on the dry pole, avoid being oppressed.
    7) Close the container door.
    8)Container dry pole, can be directly hung, easy to operate.
