Carbon molecular sieve (CMS) is a new-style nonpolarity sorbent that can absorb oxygen molecule under normal temperature and swinging pressure. As a result, the enriched nitrogen gas been generated. Its separative capacity rests on the different diffusing speed or adsorptive ability of the various kinds of gases in the air, or both the effects of the two. Carbon molecular sieve is widely applied in petroleum chemical industry, metal heat treatment, electron production, keep-fresh of foodstuff.
Main technical index of carbon molecular sieve:
1) Grain diameter: 1.5mm/2.0mm
2) Absorption periods: 260s
3) Pile proportion: 630 - 650g/L
4) Bearing strength: 100N/grain
Now we mainly supply CMS-185,CMS200.CMS220
