Nitrogen everyone knows that the air we breathe contains nitrogen. Nitrogen is usually a colorless and odorless gas. Generally, nitrogen is less dense than air. Nitrogen accounts for 78.12% of the total atmosphere and is the main component of air.

Nitrogen is chemically inactive, and it is difficult to react with other substances at room temperature, but it can chemically change with certain substances under high temperature and high energy conditions, so it is often used to prepare new substances useful to humans. Nitrogen has a very wide application range. We often see nitrogen products in our lives. For example, the puffed food we often eat is filled with nitrogen. Nitrogen not only increases the growth of microorganisms in the food, but also acts as a shockproof work. Its chemical properties are inactive and easy to prepare cheaply. The nitrogen generator is suitable for many industries, such as the petroleum and natural gas industry. In the petroleum and natural gas exploration, the nitrogen protection oil extraction is characterized by high safety, strong adaptability, and continuous production. In addition, the chemical industry and the metallurgical industry , Coal industry, rubber tire industry, pharmaceutical industry, electronics industry and other fields. So almost all industrial industries can use nitrogen generators.
