The pore silica gel is a colorless or slightly yellow transparent glass body, and its basic quality parameters are as follows: average pore distance 2.0-3.0 nm, specific surface 650-800 m 2 /g, pore volume 0.35-0.4 ml/g, specific heat 0.92 KJ /kg.°C, thermal conductivity 0.63 KJ/m. hr .°C.
Uses: Suitable for dry, moisture-proof, rust-proof. It can prevent the dampness of instruments, meters, weapons and ammunition, electrical equipment, medicines, foods, textiles and other packaging materials. It can also be used as catalyst carrier and dehydration refining of organic compounds. Because of its high bulk density and obvious moisture absorption under low humidity, it can be used as an air purifier to control air humidity. It also has a wide range of applications in the shipping process, because the goods are often damped and deteriorated due to high humidity during transportation. With this product, moisture can be effectively dehumidified and the quality of the goods can be guaranteed. Fine-pored silica gel is also commonly used for dehumidification between two parallel-sealable windows, maintaining the transparency of two layers of glass.
