Will silica gel desiccant cause harm to the human body?


In addition to being used for dehumidification and moisture-proofing of food, silica gel desiccant can also be used for medicines, machinery, optical electronics, precision instruments, meters, seeds, tea, various chemical fiber textiles, leather shoes, leather, sports shoes, cultural relics files, cameras , Arts and crafts, etc. All items that require moisture and mildew resistance are widely used. Nowadays, the desiccant is becoming more and more refined, causing accidental ingestion of desiccant incidents, especially in children, the probability of occurrence is more than 30%. Today I will mainly share with you that silica gel desiccant will really do What are the hazards to the human body!

The safety performance of silica gel: silica gel has strong adsorption capacity, is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and strong It does not react with any substances except alkali and hydrofluoric acid. It can have a drying effect on human skin. Therefore, you should wear work clothes during operation. If silica gel gets into the eyes, rinse with plenty of water and seek medical treatment as soon as possible. Silica gel desiccant is the only desiccant that has passed the US FDA certification and can be used directly in contact with food and medicine. After accidental ingestion, it will not cause harm to the human body, nor will it be absorbed by the human body, and it can be naturally excreted with feces.

Silica gel desiccant is a kind of highly active adsorption material, the main component is silica, it is a kind of highly 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 irregular side spheres, and its chemical formula is mSiO2.nH2O.  

The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. The inside of silica gel desiccant is a very fine pore network structure. These pores can absorb water and retain water through its physical attraction. As a desiccant, it is widely used in aviation components, computer devices, electronic products, and leather Dry and moisture-proof in industries such as products, medicine and food. Even if the silica gel desiccant is completely immersed in water, it will not soften or liquefy. It is non-toxic, tasteless, non-corrosive and non-polluting, so it can be in direct contact with any object.  

The suitable hygroscopic environment of silica gel desiccant is room temperature (20~32℃), high temperature (60~90℃), it can reduce the relative humidity of the environment to about 40%, so the application range of desiccant is very widely.

Silica gel desiccant has high adsorption performance and strong moisture absorption performance. Good thermal stability, non-toxic, tasteless and odorless. It is chemically stable and does not react with any substances except strong alkali and hydrofluoric acid.
