The rate of diffusion of oxygen molecules through a narrow gap in the carbon molecular sieve pore system much faster than nitrogen molecules zeolite, carbon molecular sieve nitrogen air separation is based on this performance xh11 sieve, far from equilibrium conditions before the time, by the PSA process nitrogen gas flow is separated from the air. Third, carbon molecular sieve nitrogen air separation unit of the device is generally referred to as nitrogen machine. Which process is the use of pressure swing adsorption method at room temperature (referred to as PSA) 16 molecular sieve, pressure swing adsorption for pyrogen adsorption separation process, carbon molecular sieve is adsorbed component (mainly oxygen molecules) absorption capacity due to the above principle 5a molecular sieve adsorption pressurized gas production when, in the step-down exhaust desorption of carbon molecular sieve regeneration. 4A Zeolite forming agent can also be used soap, toothpaste friction agent. Sewage 4A molecular sieve removes sewage NH3-N and Pb2 +, Cu2 +, Zn2 + ,, Cd2 + and so on. Industry, agriculture, animal husbandry and aquatic civilian discharged wastewater containing ammonia nitrogen, not only endanger the survival of fish, in the farming environment pollution, and promote algae growth, leading to blockage of rivers and lakes. 4A molecular sieve due to high selectivity of NH4 + exchangeable, has been successfully applied in the field. 5a molecular sieve | new molecular sieve (certified) | new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is Shanghai's Songjiang District, elemental leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. There are new leaders in the molecular sieve with the staff warmly welcome all inquiries negotiations to create new molecular sieve a better future.
