Detailed Description

Molecule it sifts to be one silicon aluminium sour salt of crystallization, because it with one aperture and than the surface area extremely tall one, So have a lot of excellent characteristics: (1) According to size different from beginning choice adsorption of molecule, absorb little member those sift molecule of aperture only. (2) As to small polarity molecule and unsaturated molecule, choose absorbing nature, The larger polarity is not the higher the degree of saturation is; It choose person who absorb to be better. (3) Have strong hydroscopicity, even if in higher temperature, heavy empty speed and under the low situation water content, there is quite high capacity of absorbing water. Main product that our company’s produce at industry using already have: 3A, 4A, 5A, 10X, 13X, copper molecule person who sift variety. 3A Molecular sieve Formula:0.4K2O 0.6Na2O Al2O3 2.OSiO2 4.5H2O The pore size of 3Amolecular sieve is 3A.It does not adsorb any molecular larger than 3A.According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span .All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses ,ethylene ,propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.Regeneration: it can be regenerated through the course of improving the temperature. Regeneration temperature is 180-350°C, and regeration time is 3-6 hours.
