Activated Molecular Sieve Powder Test Date Sheet

Activated Molecular Sieve Powder Test Date Sheet


Activated Molecular Sieve Powder is formed after deep processing and activation of synthetic molecular sieve raw powder. It has certain dispersibility and fast adsorption capacity; It can improve the uniformity and strength of materials; Avoid the generation of foam and extend the service life.


The main application of Activated Molecular Sieve Powder is water adsorption. Even at very low moisture situation, it can adsorb more than20% of moisture. The adsorption rate is a physical process and doesntcause any side reactions

Activated Molecular Sieve Powder Type:


Activated Molecular Sieve Powder



Nominal pore diameter

3 angstroms; 4 angstroms; 5 angstroms; 10 angstroms








Size (μm)





Bulk density (g/ml)





Static water absorption (%)





Water content (%)







Static water adsorption (wt%): at a certain relative temperature and humidity, the greater the static water adsorption capacity, the better the molecular sieve quality; Only when the relative humidity is low, the adsorption capacity can show the deep drying capacity of molecular sieve.


Bulk density (g/ml): this parameter indicates the filling density of molecular sieve, which is only for reference to customers.


Compressive strength (n/ piece): if the compressive strength of the molecular sieve does not meet the requirements, it is very easy to cause damage to the molecular sieve and affect the service life of the molecular sieve.


Package water content (%): the smaller the package water content, the less the pre adsorption water of the molecular sieve during storage and transportation, the greater the residual adsorption water, the stronger the dew point control ability and the better the quality.


Powder dropping degree (mg/m3): the lower the powder dropping, the less dust of the molecular sieve, which is more conducive to keeping the hollow glass clean and transparent, keeping the production environment clean and sanitary, and prolonging the service life of the molecular sieve filling machine.


Temperature rise t (): temperature rise refers to the temperature rise of the molecular sieve due to the heat released by the adsorbed water. Because the adsorption of water by molecular sieve is an exothermic process, the instantaneous temperature rise of molecular sieve can be used as one of the basis for judging the rapid water absorption capacity of molecular sieve. Under the same test method, the higher the instantaneous temperature rise, the stronger the water adsorption efficiency of molecular sieve (low water content or large adsorption capacity of molecular sieve).
