It is a highly active adsorbent material. The main component is silica, which is a highly active adsorbent material. It is usually produced by the reaction of sodium silicate and sulfuric acid, followed by a series of post-treatment processes such as aging and acid bubbles. Silica is an amorphous material, its shape is transparent and irregular spherical, its chemical formula is mSiO2. nH2O.
The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, chemical stability, and high mechanical strength. The interior of silica gel desiccant is a very fine pore network structure, these pores can absorb moisture, and retain water through its physical attractiveness. It is widely used as a desiccant for aerospace components, computer devices, electronic products, and leather. Products, pharmaceuticals, food and other industries dry moisture. Even if the silica gel desiccant is completely immersed in water, it will not soften or liquefy. It is non-toxic, odorless, non-corrosive and non-polluting, so it can be in direct contact with any item.
The most suitable moisture absorption environment for silica gel desiccant is room temperature (20~32°C) and high temperature (60~90°C), which can reduce the relative humidity of the environment to 40%, so the desiccant application range is very extensive.
