Molecular sieve desiccant

Introduction

Molecular sieves are highly porous crystalline metal-alumino silicates. It has a uniform pore diameter and high specific surface area and other excellent features. It only adsorb those molecules smaller than the molecular sieve aperture, and has a rather strong water absorption capacity, even at a higher temperature, larger space velocity or large water content condition. It is widely used in chemical, petrochemical, natural gas and other industries.

Molecular sieve absorbs 18% to 22% of its own weight and can hold moisture to temperatures well past 450°F (230°C). Because of its high affinity for moisture, molecular sieve is able to bring the relative humidity in packages down as low as 10% RH.

Chemical Formula

Na2O.Al2O3.2.0SiO2 .4.5H2O

Adsorption rate

Application

- Depth drying for air, gas, hydrocarbons, refrigerants gases and liquids;
- Static drying in Pharmaceutical packaging, electronic components and other easy modification material;
- Car brake ball.

Before using molecular sieve desiccant (4A), avoid pre-adsorbed water, organic gases or liquids, otherwise, it shall be renewable.
