Edible Silicon introduction to components and properties
silica gel for food is an inorganic polymer colloid material formed by polycondensation of silicic acid. Its main component is SiO_2 · nH2O, whose content is above 98%, and its chemical properties are stable. Under normal conditions, except caustic and hydrofluoric acid, do not react with any acid and alkali salt. Because it is a colloidal structure, it has many micropores and a large specific surface area. Edible silica gel has a pore diameter of about 8-10nm, a specific surface area of 300-500m2/g, and a hydrophilic surface, which has a strong absorption capacity to water. Under the condition of high humidity, its water absorption can reach more than 80%-100% of its own weight. Therefore, food grade silica gel can be used as external desiccant for food and medicine.
Main features
1. Non-toxic, odorless, high transparency, no yellowing;
2. Soft, elastic, and resistant to kinking without deformation;
3. No cracking, long service life, cold and high temperature resistance;
4. It has higher tear resistance and superior electrical performance;
it has the advantages of high transparency, no smell, no yellow, no frost spray and so on, especially solves the problem of black hose spray cream, blue product fading, soft, high tear resistance, high insulation, abrasion resistance, high temperature resistance, flame retardant, anti-aging, environmental protection, tensile resistance, etc......
