Molecular Sieve 3A Desiccant
Products Description
First, 3A molecular sieve adsorbents have excellent adsorption performance. They have extremely strong adsorption capacity for water, can quickly adsorb water, and have a large adsorption capacity. At the same time, they have good selectivity for molecules with a diameter greater than 3Å and do not adsorb these molecules, thereby achieving the separation and purification of specific substances.
Secondly, 3A molecular sieve zeolite has a high number of regeneration times. After multiple adsorption and regeneration cycles, it can still maintain good adsorption performance, so it has greater utilization efficiency and long service life, reducing the cost of use.
Finally, it has high mechanical strength, is not easy to break during use, and can withstand certain pressure and impact. At the same time, it has strong resistance to impurities and pollutants, is not easy to be contaminated, and ensures the stability of the adsorption effect.

Application Areas
1. Petrochemical Industry: It mainly used for drying of petroleum cracking gas, such as drying of unsaturated hydrocarbons such as ethylene, propylene, butadiene, and drying of polar liquids such as methanol and ethanol. 3A molecular sieve desiccant can effectively remove moisture from it and improve product quality and production efficiency.
2. Gas Drying: It can be used to dry air, natural gas, and methane gas, remove moisture from the gas, prevent moisture from condensing in pipelines and equipment to cause corrosion, blockage and other problems, and ensure gas quality and transportation safety.
Packaging and Storage
Packaging: Usually 25kg/paper bag packaging specifications are adopted, and other packaging forms include cartons, paper barrels, iron barrels, etc., which are convenient for transportation and storage.
Storage: It should be stored in an indoor environment at room temperature with a relative humidity not exceeding 90%. When storing, be careful to avoid contact with water, acid, and alkali substances, and keep it sealed to isolate the air to prevent the molecular sieve from absorbing moisture or other impurities in advance and affecting performance.
