The true 3A molecular sieve, with pH value of 8-9, belongs to weak alkali, will not corrode hollow other auxiliary materials such as aluminum strip and glue. The lattice channel of 3A molecular sieve is only 3 Angstrom, which is the smallest of all molecular sieves, and can only absorb water and not absorb any other components in the air. The water solution is clear, free of impurities and crystallites
DetailSome rare gases such as hydrogen, oxygen, nitrogen, argon and krypton
were separated from air. PSA pressure swing adsorption and low
temperature distillation were used to prepare them. The use of molecular
sieve can effectively remove water, carbon dioxide and other small
molecular impurities in these gases, thus meeting the requirements of
commercial gas.
