SILICA GEL is a material with very stable chemical properties, which is composed of silicon dioxide and water molecules. Silica gel particles exhibit a unique microporous structure inside and possess high adsorption capacity. It has a specific surface area of about 300-500m2/g, mainly mesoporous, with pore sizes distributed between 2-50nm. The internal surface of their pores has abundant surface hydroxyl groups, mainly used for adsorption drying and pressure swing adsorption to produce CO2
In the civilian field, used as a dehumidifier to absorb moisture in the air and keep it dry; used as a desiccant packaging material to prevent moisture absorption of items, also widely used as cat litter, it can effectively absorb the odor of small animal urine and faeces.
In field of food, it is used for separation and purification, removal of impurities, and is widely used in beer brewing industry.
In the industrial field, used for gas purification, natural gas separation and purification, also widely used in the synthesis of ammonia industry, pressure swing adsorption and other fields.
In the electronics industry, it plays a crucial protective role in preventing moisture, static electricity, and corrosion in the storage of semiconductors, circuit boards, and various optoelectronic components.
In the pharmaceutical and biological industry, it is most commonly used as a packaging material to prevent drugs from absorbing moisture and extending their shelf life. It is also used for the separation and purification of active ingredients in traditional Chinese medicine, preparation of high-purity substances, and dehydration and refining of organic substances.
In the field of agriculture, silica gel fertilizer can enhance the disease resistance of rice, improve seed setting rate, promote rice growth and development, and increase yield.
