What Are The Advantages Of Silica Gel Desiccant?

Jan. 22, 2019

Silica gel is a highly active adsorbent material, usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foam. Silica gel is an amorphous substance and its chemical formula is mSi02.Nh2O. It is non-toxic in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Comply with Chinese chemical standard HG/T2765-2005. It is the only FDA approved Silica Gel Desiccant that can be in direct contact with food and drug products. Therefore, it can be in direct contact with any item.

The main component of Silica Gel Desiccant Packets is silica, which is chemically stable and does not burn. It is a highly active adsorbent material which is purified from natural minerals into pellets or beads. As a desiccant, its microporous structure (average 2A) has a good affinity for water molecules. The most suitable moisture absorption environment for silica gel is room temperature (20-32) and high humidity (60-90%), which can reduce the relative humidity of the environment to about 40%. Therefore, Transparent Silica Gel Desiccant has a wide range of applications. At the same time, the chemical composition and physical structure of silica gel determine that it has the characteristics that it is difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

The advantage of Environment-friendly Desiccant is a physical adsorption desiccant, which relies on its internal capillary pores to absorb the moisture in the air, and locks the moisture firmly inside the knot. Even if it is filled with water, the appearance will not be Changed, the appearance still looks dry.

1. Silica gel is non-deliquescent, non-corrosive and insoluble in water.

2. Silica gel is tasteless and odorless and has no threat to health.

3. Even after filling with water, the silicone still feels and looks dry.

4. Has a stable quality.
