Feature | 1. Molecular sieve adsorption is a physical process that instead of a chemical changes. The adsorption process is reversible, called resolution or regeneration. 2. The zeolite molecular sieve has strong polarity in the crystal cavity, which reflects the adsorption selectivity of zeolite molecular sieve. 3. The size of the zeolite molecular sieve can be changed by ion exchange, thereby changing its performance and achieving the purpose of shape selective adsorption and separation of mixtures. 4. The surface of most zeolite molecular sieves has a strong acid center, and at the same time, a strong coulomb field in the pores has a polarizing effect. These characteristics make it an excellent catalyst. | |||||||
Application | PSA oxygen generator/home oxygen concentrator. 1. Separate N2 and O2 in the material air. 2. Absorb CO2 in the air. | |||||||
MOLECULAR SIEVE FILLING PRECAUTION | ||||||||
1.Molecular sieve should be properly kept at the site to ensure no water accumulattion.avoid rain,and protect it;2.Ensure that the packaging steel drum is completely sealed without damage and leakage 3.Avoid contact with oil to avoid contaminating molecular sieves. 4.steel drums must be placed upright to avoid rolling; 5.there may be a weak vacuum in the iron drum,the venting screw on the narrel choose a sunny day for construction |
