Introduction to Container Desiccants

Release Time：

2019-12-05

Container desiccant, also known as strong desiccant or biochemical desiccant, is mainly used inside shipping containers to absorb moisture. During ocean transport or storage, the container experiences high humidity and large diurnal temperature variations, causing water vapor inside the container to condense into water droplets, forming "container rain." The desiccant reduces the moisture content of the air inside the container to prevent this.

Container desiccant Also known as powerful desiccant, biochemical Desiccant Mainly used in sea shipping containers to absorb moisture. During ocean transport or storage, due to high humidity and large diurnal temperature differences, water vapor in the container condenses into water droplets, forming "container rain". The desiccant reduces the moisture content of the air inside the container, preventing the formation of container rain.

Product Raw Material Classification

Currently used in production Container desiccant The raw materials include: calcium chloride, silica gel, montmorillonite, quicklime. Among them, montmorillonite is preferred due to its strong and long-lasting adsorption capacity and high safety performance. Common container desiccants include 500g/stick, 1000g desiccant bags, and 1500g desiccant sticks.

Packaging Material

DuPont paper, non-woven fabric

Quality Indicators

Unit adsorption capacity: Adsorption amount RH=20% ≥60% RH=40% ≥100% RH=90% ≥200%

Note: According to GB10455-89 standard: At RH=90%, qualified products ≥160%, first-grade products ≥190%, superior products ≥220%

Product Use and Precautions

1. Desiccants are only effective in a sealed environment. Similarly, container desiccants require a sealed space to function. If the desiccant is not used in a sealed space, it will not be able to absorb the continuous inflow of moisture from the outside air.

2. Unused desiccant should be stored in a sealed container after opening, not left exposed. Desiccants must be stored in a sealed container, isolated from the outside air, to remain effective for future use. Otherwise, the desiccant will be saturated and ineffective for subsequent use.

3. Desiccant Absorption of water and moisture will increase the volume, so adequate space is needed. Do not place objects on the desiccant to compress the bag, as this can cause the contents to spill.

4. Handle with care during transportation to avoid damage to the inner and outer packaging; keep the transportation and storage environment cool and dry.
