3 working principle is the use of carbon molecular sieves, sieving editing features to achieve the separation of oxygen, nitrogen purpose. When molecular sieve adsorption of impurity gases, mesopores and macropores function as channels only, the adsorbed molecules transported to the sub-micropores and the micropores, the volume of micropores and sub-micropores is that really Adsorption. As shown in FIG Jiangsu molecular sieves, carbon molecular sieves comprise a large number of internal pores, the pores allow the kinetics of small molecules rapidly diffuse into the hole size, while limiting the entry of large diameter molecules. Due to the different sizes of the gas molecules relative diffusion rate differences, components of the gas mixture can be effectively separated. Due to the constraints of domestic zeolite molecular sieve powder, for pore size control is not very good. Market sales of carbon molecular sieve pore size distribution of 0.3 ~ 1nm, only Iwatani zeolite did 0.28 ~ 0.36nm. Carbon molecular sieve material for coconut shell, coal, resins and other molecular sieve deodorant, the first step after processing powder, then blend with the base material, the base material is to increase the strength of the zeolite powder to prevent the fragmentation of the material; second pore-forming step is activated, at a temperature of 600 ~ 1000 ℃ passed through activator, commonly metal activator water vapor molecular sieve, zeolite, molecular sieves by Shanghai new Ltd provide new molecular sieves. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
