Silica gel desiccant is a type of desiccant, this kind of desiccant is insoluble in water, and any solvent, will not produce a certain degree of toxicity. About the knowledge of desiccant, everyone is not very familiar, but there is a small packet of desiccant in the food, so what if children eat desiccant by mistake? What are the harms of desiccant?
Silica gel drying The agent is different kinds of silica gel packed in moisture-permeable pouches. The main raw material silica gel is a kind of hydrous silica with high microporous structure. It is non-toxic, odorless, odorless, chemically stable, and has strong moisture absorption properties. It is a high Active adsorption material. It is usually prepared by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid foaming.
Silica gel is an amorphous substance, its shape is transparent and irregular sphere, and its chemical formula is mSiO2·nH2O. Therefore, it is widely used in the storage and transportation of instruments, meters, equipment, leather, bags, shoes, textiles, food, medicines, etc., to control the relative humidity of the environment to prevent items from getting damp, mildew and rust. Silica gel has a strong adsorption capacity and can produce a drying effect on human skin. Therefore, you should wear work clothes during operation.
In daily life, if you unfortunately take the silica gel desiccant, don't be overly nervous, because silica gel desiccant will not cause too much threat to the body, but it will not be absorbed by the body. Milk can excrete the silica gel desiccant from the body.
