On February 18 this year, a customer from an electronic component factory in Hunan reached a cooperation with Xintao and purchased 12 tons of carbon molecular sieves from Xintao for the production of nitrogen in the factory. Considering the professionalism and importance of carbon molecular sieve filling, Xintao responded quickly and immediately sent an experienced professional technical team to Hunan.
After arriving at the site, members of our technical team quickly got to work, from the preparatory inspection before filling, to the precise operation demonstration during the filling process, to answering questions about the filling details, providing customers with all-round professional guidance, assisting customers to smoothly fill carbon molecular sieve into air compressors and dryers, and laying a solid foundation for the orderly development of subsequent production work.
After filling, the technical team immediately conducted a comprehensive and detailed test of the relevant equipment. With professional technology and rigorous attitude, the purity of the output nitrogen reached 99.99%, meeting customers’ demand for high-purity nitrogen and winning high recognition and praise from customers.
Gas Separation Principle: Carbon molecular sieve has a unique microporous structure, and its pore size distribution is within a certain range. Different gas molecules have different sizes. When the mixed gas passes through the carbon molecular sieve desiccant, smaller molecules are more likely to enter the micropores of it and be adsorbed, such as oxygen molecules, while larger molecules are more difficult to enter, such as nitrogen molecules, thereby achieving gas separation. In the manufacturing process of electronic components, this gas separation function can be used to prepare high-purity protective gases, such as nitrogen, to provide a stable environment for the production of electronic components.
Adsorption and Desorption Principle: Under certain pressure and temperature conditions, gas molecules are adsorbed on the surface and micropores of the carbon molecular sieve adsorbent; when the pressure decreases or the temperature increases, the adsorbed gas molecules will desorb from the cms, so that it can be regenerated and reused. In the cleaning and drying processes of electronic components, the adsorption characteristics of carbon molecular sieves can be used to remove impurities and moisture in the gas to ensure the quality of electronic components.
Application Scenarios Of Carbon Molecular Sieves Adsorbent
During the packaging process of electronic components, in order to prevent the internal components from being affected by the external environment, such as moisture and oxidation, it is necessary to fill the packaging cavity with protective gas. The high-purity nitrogen prepared by carbon molecular sieves pellet can be used for electronic packaging, providing a stable inert gas environment in the packaging cavity and extending the service life of electronic components.
During the production process of electronic components, they need to be cleaned and dried to remove impurities and moisture on the surface. Carbon molecular sieves can be used to dry compressed air and provide dry and clean gas for cleaning equipment to ensure the effect of cleaning and drying.
Advantages of Carbon Molecular Sieves Desiccant
Xintao carbon molecular sieve can effectively separate gas mixtures and prepare high-purity nitrogen to meet the strict requirements of gas purity in the manufacture of electronic components, thereby improving the performance and reliability of electronic components. Secondly, it has a long service life and good regeneration performance, can be reused many times, and reduces the cost of gas preparation. At the same time, it does not involve chemical reactions in the separation process, nor does it produce pollutants. It is environmentally friendly and meets the requirements of green production in the modern electronic manufacturing industry.
