The Use and Efficacy of Mineral Desiccants: Commonly seen mineral desiccants are refined from pure natural mineral raw materials and a small amount of additives, making them green, environmentally friendly, non-toxic, and odorless. The product exhibits good adsorption performance at room temperature and under normal humidity, possessing adsorption activity,
static dehumidification and odor removal functions. Mineral desiccants use pure natural raw materials, with adsorption capacity comparable to silica gel, but at a slightly lower price. The product is non-toxic and environmentally friendly; after use, it can be directly disposed of in the soil where it will decompose. Its affordability makes it currently one of the
most ideal silica gel desiccant alternatives. This is also one of the main reasons why
mineral desiccants
are becoming increasingly popular. Mineral desiccants (also called activated clay desiccants) refer to a type of clay mineral with minerals as the main component. The mineral is a crystalline hydrated aluminosilicate mineral. It has unique layered chain-like structural characteristics, with needle-shaped and fibrous aggregates.
Mineral desiccants possess unique dispersion, temperature resistance, alkali resistance, and other good colloidal properties, as well as high adsorption and decolorization capabilities. They have a certain degree of plasticity and bonding strength, with an intermediate structure between chain-like and layered structures.
Mineral desiccants appear earthy, in dense masses found in sedimentary and weathering crusts, in white, grayish-white, bluish-gray, grayish-green, or with a weak silky luster. The soil is fine and oily, light and brittle, with a
conchoidal or uneven fracture. It is highly water-absorbent, sticky and plastic when wet, and shrinks little upon drying, showing few cracks. It disintegrates when waterlogged. The suspension does not flocculate and precipitate when encountering a dielectric medium.
Mineral desiccants are non-toxic, harmless, and environmentally friendly products with excellent compatibility; they are 100% biodegradable and can be treated as general waste. Mineral desiccants can be used in electronics, metals, food, pharmaceuticals, precision machinery, communications, electronics, military industry building materials, light industrial products, containers, and various other fields requiring moisture prevention. Main characteristics of mineral desiccants:
1. No back-permeation after moisture absorption, ensuring the desiccant packaging remains dry. The physical form changes little before and after moisture absorption, preventing the "bursting of packaging bags" phenomenon.
2. Regular high-strength spherical particles increase fluidity, ensuring the product remains unbroken and dust-free during transportation, packaging, and use. Even after prolonged immersion in water, the
strength and shape remain unchanged, improving regenerability.
3. Compared to silica gel desiccants, products with the same moisture absorption rate are much cheaper. 4. Environmentally friendly and safe, widely applicable in pharmaceuticals, food, and feed. Accidental ingestion of small amounts will not endanger life. (Avoid ingestion).
5. High hygroscopicity, strong deodorizing ability, non-toxic, odorless, non-corrosive, and environmentally friendly. The moisture absorption rate is
