Application of high purity nitrogen after purification by nitrogen purification device
Nitrogen is a kind of colorless, non-toxic and odorless inert gas after purification by nitrogen purification device. With the progress of science and technology and the development of economic construction, the application range of high purity nitrogen is becoming more and more extensive, and it has penetrated into many industrial fields. Here, we will talk about the application of high purity nitrogen with Suzhou Jiarui gas, a manufacturer of nitrogen purification device. 1.Application in the electronics industry
In the production process of electronic components and semiconductor components, nitrogen with a purity of more than 99.999 % after purification by nitrogen purification device is needed as a protective gas. At present, high-purity nitrogen has been used as carrier gas and protective gas in the production process of color TV tube, large-scale integrated circuit, liquid crystal and semiconductor silicon wafer in China.
2 、 Application in the chemical fiber production process
In the production of chemical fiber, the high-purity nitrogen purified by the nitrogen purification device is often used as a protective gas to prevent the oxidation of chemical fiber products in production and affect the color. The higher the purity of nitrogen, the more beautiful the color of chemical fiber products. Nowadays, some new chemical fiber factories in China have set up high-purity nitrogen devices.
3.Applications in aerospace technology
The space is cold, black and high vacuum. Human beings need to carry out space simulation experiments on the ground first. Liquid nitrogen and liquid helium are used to simulate the space. Large space simulation chambers in the United States consume 300,000 cubic meters of nitrogen per month for large wind tunnel simulation experiments. On the rocket, in order to ensure the operation of flammable and explosive liquid hydrogen devices, nitrogen fire extinguishers are installed in appropriate parts. High purity nitrogen is also the pressure gas of rocket fuel ( liquid hydrogen-liquid oxygen ) and the cleaning gas of combustion pipeline. The aircraft prevents the combustion chamber of the engine from explosion before take-off or after landing. Usually, high-purity nitrogen purified by a nitrogen purification device is required to clean the engine combustion chamber.
Above is nitrogen.
