Deaerator and desiccant are two different chemical substances, with different uses and effects.
Deoxidizer: Deoxidizers are typically used to remove oxygen from the environment and prevent oxidation reactions caused by oxygen. It can absorb oxygen from the environment and reduce oxygen concentration. Deoxidizers are commonly used in food packaging, drug storage, electronic equipment protection, and other occasions that require oxidation prevention. Common deoxidizers include iron powder, sodium sulfide, etc., which can absorb oxygen in a sealed environment.
Desiccant: Desiccant is mainly used for absorbing moisture and regulating environmental humidity. It can absorb moisture from the surrounding air, preventing dampness and decay. Desiccants are commonly used for storing items that are prone to moisture, controlling humidity equipment, and preventing mold growth. Common desiccants include silica gel, activated carbon, gypsum, etc., which have hygroscopic properties.
Therefore, deoxidizers are mainly used to remove oxygen and prevent oxidation reactions, while desiccants are mainly used for moisture absorption, humidity control, and prevention of moisture problems. Although there are certain similarities between the two, their purposes and functions are different. In specific applications, appropriate deoxidizers or desiccants need to be selected according to the needs.
