A desiccant is a substance that can remove moisture from a wet substance, so what is a silica desiccant? Why can silica be used as a desiccant?
What is the principle of silica desiccant?
The silica porous skeleton structure formed after the dehydration of silicic acid colloid has a large specific surface area and has adsorption properties, so it can be used as a desiccant.
What is silica desiccant? What is the principle of silica desiccant?
Silica desiccant is a colorless or yellowish transparent or translucent silica crystal (also known as silica gel), so it can be called silica gel desiccant.
Silica gel desiccant has the characteristics that other similar materials are difficult to replace, such as high adsorption, good thermal stability, stable chemical properties, high mechanical strength, etc.
Silica gel is an amorphous substance. Its shape is transparent and irregular. And retain moisture through its physical attraction, aviation parts, computer devices, electronic products, leather products, food and other industries. Even if the desiccant is fully immersed in water, it will not soften or liquefy.
Therefore, the silica gel desiccant has the characteristics of non-toxic, tasteless, non-corrosive, and non-polluting, so it can be in direct contact with any object, so the application range of the desiccant is very wide. Mainly used in aviation parts, computer devices, electronic products, leather products, food and other industries. Silica gel desiccant is non-toxic, but not edible.
