The main reasons why medical oxygen concentrators use molecular sieves are as follows:1. Efficient separation:Molecular sieves can effectively separate oxygen and nitrogen in the air. This is achieved by physical adsorption, that is, molecular sieves have different adsorption capacities for oxygen a

According to the relevant provisions of the Ministry of Food and Drug Administration, medical oxygen must reach 93% of the standard before it can be put into use in clinical treatment. Why is the standard of oxygen concentration of medical oxygen generator 93%±3%?When the human body absorbs oxygen w

Two-component polyurethane adhesives are adhesives obtained by the reaction of isocyanates and hydroxyl-containing compounds, with their molecular chains containing urethane groups (-NHCOO-) or isocyanate groups (-NCO). These adhesives typically consist of two components: one is the isocyanate compo

Molecular sieves play an important role in the liquefied petroleum gas industry. They not only play a role in improving product quality, protecting the environment and equipment, but also have important significance in improving production efficiency and reducing costs.The application of molecular s
