Molecular sieve activated powder is produced by high temperature roasting of molecular sieve raw powder. Because the raw powder of molecular sieve loses most of its water during the high-temperature roasting process, the activated zeolite powder has strong activity and can be directly applied in production as an adsorbent with selective adsorption.
Molecular sieve activated powder is widely used in the production of polyurethane and other polymers, which can adsorb impurities such as water that affect product quality without changing the physical and chemical properties of the product itself. It can also be added as a selective adsorbent to specific polymers or coatings in the production process to adsorb CO2, H2S and other gases produced in the growth process. Some powdered molecular sieves can also be applied to insulating glass composite strips as desiccant or as catalyst carriers.
