Specification of 3A ,4A , 5A and 13X Molecular Sieve

2023-05-10

3A molecular sieve is a alkaline metal silicon aluminate, also known as 3A boiler molecular sieve. Type 3A molecular sieve refers to NA-A with NA+A-type molecular sieves. If NA+is replaced by K+, the aperture diameter is about 3A molecular sieves; 3A molecular sieves are mainly used to absorb water and do not adsorb any molecules greater than 3A. It is a desiccant necessary for the deep dryness, refining and aggregation of the gas and chemical industry.


5A molecular sieve is calcium siliconate. The average average pore diameter is 5 × 10-7mm, the density of the heap is 700 ~ 800kg/m3/g, the surface area of 750 ~ 800m2/g, the pore rate is 47%, the mechanical strength is greater than 95%, the water adsorption capacity is about 21%, the wear rate is 0.2% Carbon dioxide adsorption capacity is 1.5%and formaldehyde adsorption is 15%.

Compared with 5A molecular sieves, the adsorption performance of the 13X molecular screen is better than the 5A molecular screen. However, the mechanical strength and abrasion resistance of 13X molecular sieves are slightly poor, the manufacturing process is complex, and the price is higher.
