- Product Description
-
3A molecular sieve is an artificially synthesized microporous adsorption material with a pore size of 3 angles (0.3nm), composed of a silicoaluminate crystal structure. It can efficiently adsorb water molecules while repelling larger ones, featuring high water absorption rate, good thermal stability and renewability. It is widely applied in the fields of chemical engineering, refrigeration and electronics, etc.
Applications and Advantages：
- High-efficiency selective dehydration: Specifically designed for adsorbing water molecules, it is the desiccant with the highest selectivity among all types of molecular sieves.
- High adsorption capacity: In a low-humidity environment, its water absorption far exceeds that of traditional desiccants such as silica gel and activated alumina.
- Deep drying: It can reduce the dew point of gas or liquid to below -70°C, achieving an extremely low moisture content (ppm level).
- No adsorption of large molecules: It does not co-adsorb most organic substances, avoiding the loss of effective components during the drying process. It is particularly suitable for the petroleum, chemical and pharmaceutical industries.
- Still effective at high temperatures: It can maintain good adsorption capacity at relatively high temperatures (such as 150-200°C), while silica gel has been largely deactivated under such conditions.
- Renewability: By heating (typically at 200-350°C) and purging with inert gas, the adsorbed moisture can be removed, its activity restored, and it can be recycled, with a long service life and low overall cost.
- High mechanical strength: Spherical or strip-shaped particles have excellent compressive strength and wear resistance, are not prone to powdering, and are suitable for industrial tower installation.
