Calcium montmorillonite desiccant is a type of moisture-absorbing material that utilizes the properties of calcium montmorillonite clay to control humidity and prevent moisture-related issues. Montmorillonite adopts physical adsorption and can absorb more than 17% of its weight of water vapor at 25° C and RH40%. Montmorillonite particles can be reused after being reactivated. It is a natural, environmentally friendly, economical, and affordable adsorbent material.
The raw materials for Calcium montmorillonite desiccant are extracted from naturally occurring deposits of montmorillonite clay. The clay is mined from geological formations abundant in this mineral. After extraction, the clay is processed to remove impurities through methods like crushing, grinding, and screening. The processed clay is then treated to enhance its desiccant properties, sometimes involving ion exchange processes. The treated clay is formulated into desiccant products suitable for various applications, such as packaging and storage, before being packaged and distributed for use.
Environmental Friendliness: Being a naturally occurring mineral, calcium montmorillonite is considered environmentally friendly compared to some synthetic desiccants.
Regenerability: Saturated calcium montmorillonite desiccants can be regenerated through heating, making them reusable after moisture removal.
Calcium montmorillonite has relatively weaker dehumidification properties compared to traditional desiccants, such as silica gel or molecular sieves. Therefore, its application for dehumidification is relatively limited. However, it can still be effective in moisture protection for products during manufacturing and storage.
