China Carbon Molecular Sieve Co., Ltd. manufactures
carbon molecular sieves with the diameter of 1.2-1.8mm with using longer service
life than diameter of 1.1mm, They has the same nitrogen yield as carbon
molecular sieve with a diameter of less than 1.1mm
People hope that carbon molecular sieve has high nitrogen yield, long
service life and low raw gas consumption. In order to increase the
nitrogen yield, the diameter of the carbon molecular sieve(CMS) is
reduced. People make carbon molecular sieve with a diameter of less than
1.1mm. However, in the process of using carbon molecules(CMS),
if the oil and water in the air enter the carbon molecular sieve, the
carbon molecular sieve(CMS) absorbs
water and oil, which will gradually reduce the nitrogen yield and
service life of the carbon molecular sieve and the nitrogen generator.
In addition, the flushing of the airflow will cause The pulverization of
carbon molecular sieve will also reduce the nitrogen yield and service
life of the nitrogen generator. Therefore, the carbon molecular sieve(CMS) must
be vibrated and compacted when it is loaded into the adsorption tower of
the nitrogen generator. In the process of use, the air entering the
carbon molecular sieve in the adsorption tower of the nitrogen generator
is usually first dried and purified to control the oil in the air. And
the water content is below 3ppm.
The carbon molecular sieve itself should also have high strength,
suitable water and oil resistance. Thereby improving the service life of
carbon molecular sieve. However, carbon molecular sieves with small
diameters have lower strength than carbon molecular sieves with large
diameters, and carbon molecular sieves(CMS) have
a shorter service life.
China Carbon Molecular Sieve Co., Ltd. found that increasing the
nitrogen yield of carbon molecular sieves can also be achieved by
selecting appropriate pure raw materials. The lower the ash content of
inorganic salts in the raw materials for carbon molecular sieves,
especially sodium ions The smaller the content, the higher the nitrogen
yield, water resistance and oil resistance of the carbon molecular
sieve, and the longer the service life. Secondly, the raw material
powder should be crushed and ground to less than 3 microns. The finer
the raw material powder, the higher the strength of the carbon molecular
sieve(CMS).
The higher the nitrogen production rate and the higher the water and oil
resistance of the carbon molecular sieve, the longer the service life.
Therefore, the nitrogen yield of our carbon molecular sieve with a
diameter of 1.2-1.8mm is the same as that of a carbon molecular sieve
with a diameter of less than 1.1mm, but the strength of the carbon
molecular sieve(CMS) is
greatly improved and the service life is long.
Finally, China Carbon Molecular Sieve Co., Ltd. adopted a suitable
coating process to improve the water resistance and oil resistance of
the carbon molecular sieve(CMS) and
increase the service life of the carbon molecular sieve.
China Carbon Molecular Sieve Co., Ltd. uses pure raw materials that do
not contain inorganic salt ash, advanced hole adjustment technology,
advanced grinding and coating processes to produce carbon with a
diameter of 1.2-1.8mm with long service life, high nitrogen yield and
low air consumption. Molecular sieve. It has the same nitrogen yield as
carbon molecular sieve with a diameter of less than 1.1mm, but the
strength is greatly increased and the service life is increased
