In many fields of industrial production, the application of nitrogen is very extensive. Membrane separation nitrogen production equipment, as an efficient and convenient method of nitrogen production, is gradually emerging. What material does the 'membrane' that plays a key role actually consist of? Today, let's unveil its mysterious veil together.
The membrane in membrane separation nitrogen production equipment mainly uses hollow fiber membranes. These hollow fiber membranes are usually made from organic polymer materials, commonly including polysulfone and polyimide.
Polysulfone material has excellent chemical stability and can withstand the erosion of various chemical substances, allowing it to work stably in complex industrial environments. It also has good heat resistance, not easily deforming or damaging under certain high-temperature conditions, providing reliable protection against temperature fluctuations during the membrane separation nitrogen process. Additionally, polysulfone has high mechanical strength, enabling the hollow fiber membrane to maintain its structural integrity during long-term operation without easily breaking, greatly extending the membrane's lifespan.
Polyimide is renowned for its outstanding high-temperature resistance. In some nitrogen production processes that require higher temperatures, polyimide hollow fiber membranes can handle them with ease. It also possesses excellent gas separation performance, allowing for more precise separation of nitrogen from air, improving the purity and efficiency of nitrogen production. Moreover, polyimide materials have strong anti-aging capabilities, maintaining their performance over long periods and reducing the frequency of equipment maintenance and membrane component replacement, thus lowering production costs.
These hollow fiber membranes have unique structural characteristics. They are composed of countless extremely thin hollow fiber strands, each strand acting like a tiny 'sieve.' When air enters the membrane module under certain pressure, due to differences in solubility and diffusion rates of different gas molecules in the membrane, oxygen and carbon dioxide pass through the membrane wall more easily than nitrogen, while nitrogen is enriched on the inner side of the hollow fiber membrane, thus achieving separation and production of nitrogen.
The membrane materials in membrane separation nitrogen production equipment have become key factors in the field of nitrogen production due to their unique performance and structure. With the continuous development of materials science, it is believed that even higher quality and more efficient membrane materials will be developed and applied in the future, further promoting advancements in membrane separation nitrogen technology and providing purer and more stable nitrogen supply for various fields such as industrial production.
