Silica gel desiccant is a kind of physical adsorption desiccant, the main component is silicon dioxide (SiO2), which is usually prepared by reacting sodium silicate and sulfuric acid, and through a series of post-treatment processes such as aging and acid foaming. Silica gel desiccant is insoluble in water and any solvent, non-toxic and tasteless, chemically […]

1. The composition of silica gel desiccant is high-purity irregularly shaped silica. 2. A large internal surface area is formed between molecules. 3. Silica gel is chemically inert unless it comes into contact with high fluorine or strong alkali substances. 4. Silica gel is non-damping, non-corrosive and insoluble in water. 5. Silica gel is tasteless, […]

If the physical and chemical laboratory has a constant temperature drying oven, it is more convenient, put the color-changing silica gel into a moisture-proof aluminum box or other high-temperature resistant containers, open the lid and put it in the drying oven to dry, until the color-changing silica gel returns to normal blue. If you don’t […]
