Clay desiccant, the appearance of the shape of the gray ball, the most suitable moisture absorption in the environment below 50 °C. When the temperature is higher than 50°C, the degree of "water release" of the clay is greater than the degree of "water absorption". But clay has the advantage of being cheap.
Montmorillonite desiccant has been discovered and used in the field of desiccants since the 1980s by German Southern Chemicals. Due to its low price and good adsorption effect, montmorillonite desiccant has gradually become one of the international mainstream mineral desiccant raw materials.
Montmorillonite desiccant is also called bentonite desiccant and clay desiccant.
Montmorillonite desiccant colors are: purple, gray, purple.
