1. Applications in the electronics industry
In the production of electronic components and semiconductor components, nitrogen purified by nitrogen purification units to a purity of more than 99.999% is required as a protective gas. At present, high-purity nitrogen has been used as carrier gas and protective gas in China for the production of color TV picture tubes, large-scale integrated circuits, liquid crystals, semiconductor silicon wafers and other products.
2. Applications in chemical fiber production
In chemical fiber production, high-purity nitrogen purified by nitrogen purification units is often used as a protective gas to prevent chemical fiber products from being oxidized during production, which would affect their color and luster. The higher the nitrogen purity, the better the color of the chemical fiber products. Today, some newly built chemical fiber plants in China are equipped with high-purity nitrogen production facilities.
3. Applications in aerospace technology
Outer space is cold, dark and high-vacuum. Before humans go into space, space simulation tests must be carried out on the ground. Liquid nitrogen and liquid helium are used to simulate outer space. Large space simulation chambers in the United States consume 300,000 cubic meters of nitrogen monthly for large wind tunnel simulation tests.
On rockets, nitrogen fire extinguishers are installed at appropriate positions to ensure the safe operation of flammable and explosive liquid hydrogen systems. High-purity nitrogen also serves as the pressurizing gas for rocket fuel (liquid hydrogen–liquid oxygen) and the purging gas for combustion pipelines.
Before takeoff or after landing, aircraft engines usually use high-purity nitrogen purified by nitrogen purification units to purge engine combustion chambers and prevent explosion risks.
The above is information about the applications of high-purity nitrogen after purification by nitrogen purification units, compiled by Suzhou Jiarui Gas. We hope this will be helpful to you.
