When testing the moisture absorption effect of desiccants, some customers open the outer bag of the desiccant and only take the desiccant raw material (granules or powder) for testing. This approach is also incorrect.
Do Desiccant When testing the moisture absorption effect, some customers open the desiccant's outer bag and only test the desiccant raw material (granules or powder), which is incorrect practice and should not be done.
Reason: First, it confuses Desiccant the concepts of raw materials and finished products. Desiccant raw material refers to the inner packaging of the desiccant, which is the content inside the desiccant. Any type of desiccant content can be called desiccant raw material. Some desiccant finished products are composed of a single desiccant raw material, such as silica gel desiccant and mineral desiccant, while some desiccants are formed by mixing two or more chemicals (e.g., Sea Dry desiccant, calcium chloride desiccant).
Secondly, it overlooks the role of the desiccant's outer packaging bag in the finished desiccant product. The desiccant's outer packaging bag is an Desiccant inseparable part. Therefore, when conducting tests, one cannot merely test the raw material content. In fact, to some extent, the packaging material is more important than the raw material. Especially in food and drug packaging, the part of the desiccant that directly contacts the product is its packaging material. Moreover, properties such as packaging material strength and breathability directly determine the quality of the desiccant.
