The fine pore silica gel is a colorless or slightly yellow transparent glass body. Its basic quality parameters are as follows: average pore spacing 2.0-3.0MM, specific surface 650-800 m2 /g, pore volume 0.35-0.4ml/g, specific heat 0.92KJ /kg. °C, thermal conductivity 0.63KJ / m · hr. ° C.
 It is suitable for drying, moisture proof and rust prevention. It can prevent the moisture of instruments, meters, weapons and ammunition, electrical equipment, medicines, food, textiles and other packaging materials. It can also be used for dehydration and purification of catalyst carriers and 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 is also widely used in the sea, because the goods are often deteriorated due to humidity during transportation. The fine pore silica gel can effectively remove moisture and moisture, so that the quality of the goods can be guaranteed. Fine pore silica gel is also commonly used for dehumidification between two parallel sealing window panels to maintain the transparency of the two layers of glass.
