What is silica gel? What is the composition of silica gel?

Usually, it is difficult to notice the existence of silica gel, but silica gel is widely used in various places of our lives, household appliances, precision instruments, clothing leather, food, medicines, etc. Silicone has so many uses, so what material is it made of?

The following small series will explain to you what the main components of silica gel are.

Silica gel can be divided into: large pore silica gel, B silica gel, coarse pore silica gel, fine pore silica gel according to its pore size; it is divided into extruded silica gel and molded silica gel according to its composition; it can be divided into organic silica gel according to its nature and composition. There are two major categories of inorganic silica gel. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel has a strong ability to absorb moisture, so it should be stored in a dry place, and there should be a shelf between the package and the ground. The packaging materials include steel drums, paper drums, cartons, plastic bottles, polyethylene plastic composite bags, and flexible container bags. Rain, moisture and exposure should be avoided during transportation.

The composition of silica gel: the main component of silica gel is silica, which is chemically stable and does not burn. Silica gel is an amorphous silica. The dust content in the workshop should be no more than 10 mg/m3. It is necessary to strengthen the exhaust and wear a mask during operation.
