Under what circumstances can the lithium oxygen molecular sieve meet the standard?

A synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. Its general chemical formula is (M'2M)O·Al2O3·xSiO2·yH2O, and M' and M are monovalent and divalent cations such as K+, Na+, Ca2+, Ba2+, etc. respectively. It has many channels with uniform pore size and neatly arranged pores in its structure, and molecular sieves with different pore sizes separate molecules of different sizes and shapes. According to the different molecular ratios of SiO2 and Al2O3, molecular sieves with different pore sizes are obtained. Its models are: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10Z (calcium Z type), 13Z (sodium Z type), Y (sodium Y type), sodium mordenite type Wait. It has high adsorption capacity, strong selectivity and high temperature resistance. It is widely used in organic chemical industry and petrochemical industry, and it is also an excellent adsorbent for gas dehydration. It has also received increasing attention on exhaust gas purification.
1 Product introduction
With the spread of the epidemic around the world, countries have their own advantages in controlling the epidemic. At the beginning of this year, the deterioration of the epidemic in India has also brought a wave of dividends to the medical device industry. The oxygen generators, masks and gloves of major manufacturers are in short supply. One of the products driven together is the lithium molecular sieve produced by our factory. The principle of the oxygen generator is to use the adsorption performance of the molecular sieve, through the physical principle, with the oil-free compressor as the power, to separate the nitrogen and oxygen in the air, and finally get high concentration of oxygen. Using zeolite molecular sieve as adsorbent, it is an automatic equipment that uses the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating oxygen.
Oxygen generator is a type of machine for producing oxygen. Its principle is to separate oxygen and nitrogen through the different adsorption capacities of adsorbents for oxygen and nitrogen under the action of pressure. Such machines are generally oil-free with high power. In terms of the compressor as the power, the molecular sieve is used as the adsorption medium, and the oxygen and nitrogen in the air are separated through the cooperation of the four-way valve and other components, and finally high-concentration oxygen is obtained.
The usual medical oxygen generator is 5-10L, and the oxygen concentration requirement for molecular sieve is 93±3. It is also one of the key parameters to detect whether the 0.4-0.8mm lithium molecular sieve meets the standard. Since the current market capacity cannot keep up with the demand, there are Various manufacturers use sodium sieves to confuse customers, resulting in the return of customers with oxygen concentration lower than 90% after export testing. It is necessary to clearly identify that although sodium sieves can also produce oxygen, their oxygen concentration is only for industrial oxygen production and medical use. Oxygen production requires lithium sieves to reach the standard
Using molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. The molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can absorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve is not consumed.
