Static water adsorption of which the unit is weight percent
Under a certain relative temperature and humidity, greater the static water adsorption capacity can get better molecular sieve quality. Only at low relative humidity, the amount of adsorption capacity can demonstrate the level of deep drying ability of molecular sieve.

Bulk density of the unit of g/ml
The parameter indicates the loading density of molecular sieve, only providing a reference for customers.

Compressive strength of which the unit is N/Unit
Compressive strength of molecular sieve which does not meet the requirement may easily lead to the damage of our product and also affect its service life.

Moisture content of packaging with the unit of percent
Less moisture content of packaging shows worse water pre-adsorption effect, more remaining adsorbed water, greater control ability of its dew point and better quality of molecular sieve during the process of storage and transportation.

Extent of powder out of which the unit is mg/m³
Lower extent of powder out gives fewer molecular sieve dust, which is more conducive to keep insulating glass clean and transparent, as well as keep the production environment clean, and extend the life of molecular sieve filling machine.

Temperature rise, also written as △t, with the unit of℃
Temperature rise means the rise of temperature of molecular sieve due to the heat released from adsorbed water. For the exothermic process as water adsorption process of molecular sieve, the instantaneous temperature rise of molecular sieve can be used as one of the basis for the ability to determine the molecular sieve rapid absorption. By the same test method, higher instantaneous temperature rise illustrates stronger water adsorption performance of molecular sieve, or low molecular sieve moisture content or great adsorption capacity.

Factors affecting the temperature rise
A. Related to the measurement method
a) The temperature rise is influenced by the amount of sampling. Greater amount of molecular sieve means more absorbent, more heat release and higher temperature rise.
b) It is relevant to whether the shape and material of measuring container is good to heat output.
c) Besides, there is an influence in the sensitivity of the thermometer. More sensitive thermometer can result in more accurate result used for measured temperature rise.
B. In thinking of water content of molecular sieve, lower water content means higher content of more sieve adsoption and higher temperature rise.
C. Concerned with water content of molecular sieve, lower water content shows more severe adsorption and higher temperature rise.
D. Also, the temperature rise is in connection with effective adsorption capacity of molecular sieve. Higher content of the original powder of molecular sieve may bring about higher efficient adsorption capacity and high temperature rise.
E. What is more, our product is relevant to whether the molecular sieve is true. Thus, high temperature rise does not necessarily be applied to molecular sieve.
