Silica gel, also known as silica gel, is a porous material commonly found in a variety of everyday products, such as food desiccants, medical supplies, and electronic products. It has many unique properties that make it moisture absorption, adsorption, and protection in a Wide range of applications. Here we come to know some basic knowledge of silica gel.

1. Preparation method:
Silica gel is mainly prepared by the reaction between water glass (basic silicate) and acid. During the preparation process, the water glass will gradually polymerise to form macromolecules, forming a colloidal state, and then drying it to make it into a porous solid gel.

2. Porous structure:
The unique feature of silica gel is its porous structure. These tiny pores trap water and other liquids, giving them excellent performance in applications such as drying, wicking and filtration. The pore structure of silica gel can also be adjusted as needed to meet the requirements of different applications.

3. Moisture absorption properties:
Silica gel is an excellent moisture absorber. It can quickly absorb moisture in the air and maintain relative humidity, thus protecting some humidity-sensitive items, such as food, medicines, artwork, etc. Silicone can be used over and over again, it only needs to be heated and regenerated periodically.

‍‍4. Adsorption performance:
Silica gel has a strong adsorption capacity and can adsorb many organic compounds, gases and particles. This makes silica gel have a wide range of applications in gas purification, air deodorisation and liquid purification, such as for car deodorisation and shoe deodorisation.

5. Food safety:
Silica gel is usually used as food desiccant, it will not release harmful substances while absorbing moisture, so it is harmless to food safety. However, please note that do not eat silica gel directly to avoid accidental ingestion.

6. Medical applications:
Silicone also has some applications in the medical field. It can be used to make some medical aids, such as orthotics, prosthetics, etc., because it has a certain degree of elasticity and durability.

7. Electronic industry:
Silicone also has a wide range of applications in the electronics industry, such as for the encapsulation and protection of electronic components, because it has good resistance to humid environments and some chemicals.

In short, silica gel is a multifunctional material; its porous structure gives it many unique properties, so that it has a wide range of application prospects in the field of moisture absorption, adsorption and protection. In our daily life, we can commonly see the silica gel figure, it with its special features in various fields to bring convenience and protection for our life.
