The working principle of
Nitrogen machine is based on the principle of pressure swing adsorption, using carbon molecular sieve as adsorbent, at rated pressure, nitrogen from the air. After purifying and drying the compression pressure, the adsorption is carried out in pressure adsorption and decompression desorption. Due to the aerodynamic effect, the diffusion rate of oxygen in carbon molecular sieve micropores is much higher than that of nitrogen, oxygen is preferentially adsorbed by carbon molecular sieve, and nitrogen is enriched in the gas phase to form the finished nitrogen. After decompression to normal pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. In general, two adsorption towers are set in the system, one tower adsorption nitrogen production, the other tower desorption regeneration, through PLC program controller control pneumatic valve opening and closing, so that the two towers alternately, in order to achieve the purpose of continuous production of high quality nitrogen.

Industry application
1.SMTSMT industry application
Surface Mount Technology (SMT) of electronic circuit is called Surface Mount Technology. It is a Circuit assembly technology in which the pin-free or short-lead surface assembly component (SMC/SMD for short) is installed on the surface of the Printed Circuit Board (PCB) or the surface of other substrate, and is welded and assembled by reflow soldering or dip welding. Nitrogen filled reflow soldering and wave soldering, nitrogen can effectively stop the oxidation of solder, improve the wettability of welding stream, speed up wetting speed to reduce the production of tin ball, avoid bridging, reduce welding defects, and get better welding quality. Nitrogen purity greater than 99.99.99 or 99.9%99.9%
