1, safety performance silica is the main component of silica, chemical stability, non-toxic.
2, silica gel has a strong adsorption capacity, can produce drying effect on human skin. If silicone gets into the eye, rinse with plenty of water and seek medical attention as soon as possible.
3, blue silica gel contains a small amount of cobalt chloride, toxic, should avoid food contact and inhalation mouth, such as poisoning should immediately seek medical treatment.
Silica gel is a kind of highly active adsorption material, belongs to the amorphous substance, its chemical molecular formula is mSiO2·nH2O. Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substance. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.
