The main characteristics of desiccant include high-efficiency moisture absorption, environmental safety, ease of use and wide application. Desiccant can quickly absorb moisture and keep the environment dry. It is widely used in product storage and transportation in various fields. Common types of desiccant and their characteristics are as follows:
Silica gel desiccant: The main component is silicon dioxide, which has a microporous structure and can absorb moisture equivalent to about 30% of its own weight. It is non-toxic, tasteless, odorless, chemically stable, reusable, and suitable for the storage and transportation of instruments, meters, equipment, leather, bags, shoes, textiles, food, medicines, etc.
Clay desiccant (montmorillonite): The main component is bentonite, with a gray ball appearance, suitable for use in an environment below 50°C. It is cheap, non-toxic and tasteless, and harmless to the human body. It is widely used in optical instruments, electronic products, medical care, food packaging, and dry air sealing of military products and civilian products.
Chemical desiccant: Including calcium oxide, calcium chloride, etc., which are dried by combining with water to form hydrates. For example, calcium chloride desiccant can absorb 300% of its own weight in water and has good adaptability to changes in external humidity.
Mineral desiccant: It is composed of several natural minerals, with the appearance of gray-white balls, non-toxic and harmless, and is a degradable and environmentally friendly desiccant with a moisture absorption rate of more than 50%.
Fiber desiccant: It is made of pure natural plant fibers through special processes. It is safe and hygienic, moderately priced, and suitable for drying biological, health food and medicine.
These desiccant are widely used in various environments that require moisture-proofing due to their high efficiency in moisture absorption, environmental safety, and ease of use.
