As a product with a wide range of uses, bentonite clay can be used in many directions. For example: foundry, metallurgy, and engineering construction. But today, if the editor said that it can be used to produce desiccant, it would be a bit unexpected. Today, I will share with you the working mechanism and application of china Bentonite Desiccat.

How china Bentonite Desciccat works

1. Hydration of exchangeable cations between layers: using montmorillonite with complete dehydration, the interlayer spacing is 0.96 μm. The type of cations and the degree of hydration between the layers are different, and the crystal spacing is different. At the same temperature, the interlayer spacing of different media is different, and the dry montmorillonite has strong hygroscopic performance. Under natural conditions, the interlayer spacing is about 1.2-1.5μm. Different and different hygroscopicity, and calcium-based montmorillonite wall sodium-based montmorillonite has a large water-swelling capacity, especially under low temperature conditions. The china Bentonite Desciccat produced with bentonite has numerous honeycomb-like pores, a relatively large surface, large exchange capacity, and good hygroscopic performance.
2. Due to the negative charge on the surface of montmorillonite, there is an electrostatic field on the entire surface of the particle, so its dipolar water molecules are bound to be aligned. The bare oxygen atoms on the surface of the silicon-oxygen tetrahedron crystal can form hydrogen bonds with the HO- of water molecules, and the water molecules near the surface of the montmorillonite can bond with the oxygen atoms of the quinoxe tetrahedron through hydrogen bonds. The larger the size, the stronger the hygroscopic performance.

Application of china Bentonite Desiccat

China Bentonite Desiccat is harmless to human body, has good adsorption performance at room temperature, and has the functions of adsorption activity, static dehumidification and odor removal. It is widely used in products that cannot be sealed by oil seal and gas phase, such as: electronic products, medical care, optical instruments, food packaging, civilian products, container shipping, etc. In addition to moisture absorption, it can also absorb other harmful gases.
