Silicagel is an adsorbent material with a rich microporous structure, high specific surface area, and high activity. The basic component of silicagel is silicon dioxide, which exhibits excellent thermal stability, chemical stability, and high mechanical strength. It is widely used for the separation and purification of active ingredients in biomedicine, traditional Chinese herbs, chemically synthesized substances, and bioactive materials; for producing high-purity substances through adsorption separation; for adsorbing high-molecular protein substances in industrial fermentation processes; for dehydration and refining of organic materials; for removing impurities from edible vegetable oils and petroleum products; for drying industrial gases, moisture-proofing items and environments, and serving as a catalyst or catalyst carrier in the chemical industry. Silicagel is a series of products that can be manufactured with different microporous structural characteristics according to application requirements.
