Features and Advantages of Silica Gel Desiccant

Features and advantages of silica gel desiccant
Silica gel desiccant is a kind of physical adsorption desiccant rather than chemical reaction moisture absorption desiccant, and silica gel is the only FDA approved desiccant raw material that can directly contact with food and drugs. Compared with other desiccants, silica gel desiccant is safer when used in food moisture proofing. In addition to the above factors, silica gel desiccant also has strong moisture absorption capacity and strong adsorption performance. Soak the silica gel desiccant in water, and it will not melt. It is non-toxic, tasteless, non-corrosive and non-polluting, and will not be absorbed by the human body even if swallowed.
1. Silica gel desiccant is insoluble in water and any solvents.
It is non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkalis and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical organization and physical structure of silica gel determine that it has many characteristics that other similar materials are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
2. The safety performance of silica gel desiccant
The main component of silica gel desiccant is silica, which is chemically stable and does not burn. Silica gel is a kind of amorphous silicon dioxide. The dust content in the workshop should be controlled not to be more than 10 mg/m3, ventilation should be strengthened, and a mask should be worn during operation. Silica gel has a strong adsorption capacity and can produce a drying effect on human skin. Therefore, you should wear work clothes during operation. If silica gel gets into the eyes, rinse with plenty of water and seek medical treatment as soon as possible.
3. Storage and packaging
Silica gel desiccant has strong moisture absorption capacity, so it should be stored in a dry place. There must be a shelf between the packaging and the ground. Packaging materials include steel drums, paper drums, cartons, plastic bottles, polyethylene plastic composite bags, flexible container bags, etc. Avoid rain, dampness and exposure to the sun during transportation.
