Profile: Huzhou Qiangma Carbon Molecular Sieves Co.,Ltd specializes in research and production of carbon molecular sieves. Our carbon molecular sieve is a carbon material without polarity. It is used for separating nitrogen from air. In dynamics, carbon molecular sieves has different adsorptive rate for oxygen and nitrogen. Because of malfunctions in the air pretreatment facilities or poor air supply, the carbon sieve get polluted and poisoned, which causes the considerable decrease of gas-producing rate as well as the concentration. So we provide Pressure Swing Adsorption (PSA) service for the regeneration and activation of carbon molecular sieves.
