When producing a carbon molecular sieve desiccant Changzhou, according to the size of the molecular size, carbon molecular sieves inside the pore distribution should be 0.28 ~ 0.38nm. Within this pore size range, the oxygen can quickly diffuse into the hole through the porous openings, and the nitrogen is difficult through the porous opening, so as to achieve an oxygen, nitrogen separation. Microporous carbon molecular sieve pore size is the separation of oxygen, nitrogen base, if the pore size is too large Shaoguan desiccant, oxygen, nitrogen, into the pores of the molecular sieve is easy, but there is no separation of the role; pore size is too small, oxygen, nitrogen can not enter the pores of, but there is no separation. [1] Edit a major models of ZTCMS-185 ZTCMS-200 ZTCMS-220 Second, the principle of carbon molecular sieve nitrogen air separation of the products are carbon adsorbent is a porous material composed of carbon, the pore structure of the model is not Order accumulation of carbon. Carbon molecular sieve desiccant is non-stoichiometric compounds, important properties which is based on its cellular structure. Its ability to separate the air, depending on the air at the rate of diffusion of gases differ in Jiangning microporous carbon molecular sieve desiccant adsorption or different, or the two effects simultaneously. Under equilibrium conditions, carbon molecular sieve adsorption of oxygen and nitrogen is very close, Dalian _ new molecular sieve desiccant (certified) _ new molecular sieve desiccant from 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.
