Is a kind of highly active adsorption material, the main component is silica, is a kind of highly active adsorption material.
Usually with sodium silicate and sulfuric acid reaction, and aging, acid bubble and a series of post-treatment process. Silica gel is an amorphous substance, its shape is transparent irregular sphere, its chemical formula is Msio2. nH2O.
The chemical composition and physical structure of silica gel determine that it has many other similar materials difficult to replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength and so on. Silica gel desiccant is a very fine pore network structure, these pores can absorb water, and retain water through its physical attraction, as a desiccant is widely used in aviation parts, computer devices, electronic products, leather products, medicine, food and other industries of dry moisture. Even if the silicone desiccant is fully immersed in water, it will not soften or liquefy. It has the characteristics of non-toxic, tasteless, non-corrosive and pollution-free, so it can contact with any articles directly.
Silica gel desiccant is the most suitable hygroscopic environment for room temperature (20~32℃), high temperature (60~90℃), it can
reduce the relative humidity of the environment to about 40%, so the desiccant application range is very wide.
