How many kinds of desiccant are there?

The most common desiccants are molecular sieve activated alumina and silica gel. The molecular sieve is a crystalline sodium aluminosilicate (synthetic zeolite), which has a cubic crystal structure and can be selectively adsorbed depending on the size and polarity of the molecules. Molecules of crystalline structure vary in size. This allows some molecules, such as water, to be adsorbed; Colleagues allow other large Numbers of molecules, such as refrigerants, lubricants and acids, to pass through. The surface of the desiccant is full of cations, which, as magnets, can absorb polar molecules, such as water, which can be absorbed tightly. The water molecules can be separated from the lubricating oil, which greatly reduces the possibility of hydrolysis reaction of the lipid lubricating oil. Pyroalumina, which is made of aluminum oxide (AL2O3), is not a very good crystalline material. Both alumina and silica showed a wide variety of pore sizes and did not show that they were selective based on molecular size. In addition to being able to absorb water from their surfaces, they can also absorb large amounts of refrigerants, lubricants, and acid molecules due to their diverse pore sizes. After the water and lubricating oil were adsorbed into the alumina pores, the brilliant bone hark rate also provided the opportunity for lubricating oil hydrolysis. Silica gel is a kind of amorphous molecular material with silica binding and polymerization. The colloidal desiccants indicate a weak bond between water and desiccants. Silica gel is an old form of desiccant and is not used much in today's desiccant filters.
