Nitrogen as we all know, in the air we breathe contains nitrogen, nitrogen normally is colorless and odorless, and nitrogen is smaller than air density, atmospheric nitrogen accounted for 78.12% of the total, is the main component of the air.
The chemical properties of nitrogen is inert, at room temperature is difficult to react with other substances, but at high temperature and high energy conditions can undergo chemical changes and certain substances, so often used to produce new substances useful to human beings. The scope of application of nitrogen is very wide, our life can often see the figure of product of nitrogen, for example, we often eat puffed food inside, filled with nitrogen, nitrogen not only inhibited the growth of microorganisms in food, more as a shock, and chemical nature of nitrogen is not lively and easy to produce cheap.

How is nitrogen made out? Nitrogen making machine, but it is made by nitrogen making machine, nitrogen machine using air as raw material, using physical method to separate oxygen and nitrogen, so as to obtain nitrogen. According to the classification methods, namely cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation method.
Nitrogen making machine is applicable for many industries, such as petroleum and natural gas industry, the protection of nitrogen production in oil and gas exploration, and has the advantages of high safety, strong adaptability, continuous production for features, in addition, the chemical industry, metallurgical industry, coal industry, rubber tire industry, pharmaceutical industry, electronics industry and other fields. So, almost all industries can use nitrogen making machine.
