At present, the silica gel desiccant (transparent round bead particles) is commonly used as the desiccant, because the silica gel desiccant is non-toxic, environmentally friendly, and has a high moisture absorption rate, which is suitable for most products that require safety. What are the applications of silica gel desiccant? Let me explain to you below.
Rust is widely used in pharmaceuticals, machinery, shoes and hats, tea, seeds, clothing, handbags, furniture, toys, crafts, cultural relics archives, photographic equipment, because of its non-toxic and environmental protection and direct contact with food. Gifts, wood products, lighting, precision instruments, electronics, computer containers and other items, static absorption of packaging and sealed space to remove moisture, control relative humidity, and play a role in preventing moisture and mildew.
Silica gel desiccant is a kind of highly active adsorption material, which is usually prepared by a series of post-treatment processes such as aging and acid foaming. Silicic acid is an amorphous substance, and its chemical formula mSiO2.nH2O. Is insoluble in water and any solvents. Non-toxic and odorless, chemically stable, does not react with any substance except strong base and hydrofluoric acid. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical structure 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. It is one of the most environmentally friendly and safe desiccants in the desiccant category, and it is also the only desiccant for food and medicine.
