molecular sieve is a material with uniform-sized pores that selectively adsorb molecules based on their size and shape.

Use high activated alumina as material, Has certain pore structure and surface activity and porous activated alumina absorbent

Use activated alumina ball as carrier, KMnO4 is a purple-black crystal, has high stability.Activated Alumina Impregnated with KMnO₄

Carbon molecular sieve is an excellent adsorbent, its micropore affinity to oxygen molecules is strong, can be used to separate oxygen and nitrogen in the air.

Honeycomb molecular sieve is a combination molecular sieve of hydrophobic with different pore sizes, zeolite honeycomb structure has very excellent organic waste gas adsorption performance and good gas permeability.
