Characteristics of 4A Molecular SievesThe pore diameter of 4A molecular sieve is approximately 4 Å (0.4 nm), which is the origin of its name "4A". This specific pore size determines that it can adsorb molecules of a certain size, but cannot adsorb molecules with a diameter larger than this size. Due

What is 3A Molecular Sieves

In the factory's air compression system, most factories have extremely high requirements for the quality of compressed air. The general pressure dew point is -70℃ or -40℃. Therefore, drying equipment - adsorption dryers are almost always used. The drying agents commonly employed are mainly two types

Molecular sieves are commonly used and highly efficient absorbents for water and carbon dioxide. It is precisely because molecular sieves have the dual functions of dehydration and carbon dioxide absorption that they are relatively ideal inhibitors of water and carbon dioxide in polyurethane adhesiv
