Some Specific Differences in Oxygen

Oxygen can be divided into medical oxygen and industrial oxygen. Regarding the specific classification of oxygen and the differences between them, let me give you a comprehensive explanation of this aspect.
The difference between medical oxygen and industrial oxygen is: the control of moisture in oxygen, we often have such experience in life, the surface is smooth, and the iron without rust will not rust in the open air for a long time, but a heavy rain Afterwards, it will be rusty. This is because oxygen will oxidize a large number of iron molecules when there is water, and after iron oxidation, not only rust but also hydrogen and other gases harmful to human body will be discharged, and iron will be oxidized. Rust is formed after oxidation. Rust is very loose, and it is easy to form small particles mixed with oxygen, which can be inhaled by patients and cause respiratory damage such as infection. Therefore, it is extremely important to reduce the moisture content in oxygen to the greatest extent in the production of medical oxygen.
Industrial oxygen is a gas used in industrial production and product processing. The quality requirements are relatively low, and the purity of more than 99% is generally required to be qualified. The filling procedures are not as strict as medical oxygen, and moisture and other impurities are often mixed in and remain in the oxygen cylinder. , the water mixed into and remaining in the steel cylinder will cause the inner wall of the oxygen cylinder to rust, which will cause the gas in the cylinder to have a peculiar smell. At the same time, there are carbon monoxide, carbon dioxide, acetylene and other impurities that are extremely harmful to the human body in the industrial oxygen. Once the patient inhales excessive, Coughing, crusting and other phenomena will occur, causing or aggravating the symptoms of the respiratory system.
Medical oxygen is also known as dry oxygen. The purity of medical oxygen is required to be above 99.5%. In addition to removing harmful gases to the human body during the production and filling process, the most important thing is to strictly control the water content in oxygen. Since medical oxygen is inhaled in vivo and is widely used in medicine.
