Difference between class a molecular sieve and class B desiccant
2021-03-10
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

Application field of molecular sieve 1 - air separation
2021-03-10
Some 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.
