The main component of liquid silicone is mSiO2 · nH2O, which is a highly active adsorption material and belongs to the amorphous state. Liquid silicone is insoluble in water and any solvent, non-toxic and odorless, with stable chemical properties. It does not react with any substance except strong bases and hydrofluoric acid. Different types of silicone gel form different microporous structures due to different manufacturing methods, which determine that silicone gel has high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. According to the size of pore size, silicone can be divided into macroporous silicone, macroporous silicone, B-type silicone, and microporous silicone. Silicone with different pore structures has different adsorption properties. Coarse pore silica gel has a higher adsorption capacity at high humidity, while fine pore silica gel has a higher adsorption capacity than coarse pore silica gel at low humidity. The adsorption capacity of B-type silica gel is between coarse pore silica gel and fine pore silica gel. Macroporous silica gel is mainly used as a catalyst carrier, extinction agent, toothpaste abrasive, etc. Liquid silicone has a strong adsorption effect, which can quickly and effectively adsorb water inside sealed packaging. It has stable chemical properties, is non-toxic and harmless. In recent years, liquid silicone has been widely used in fields such as drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification, beer purification, advanced coatings, and resin production or preservation. After silica gel adsorbs moisture, it can be regenerated through methods such as exposure to sunlight, calcination, and air drying.
