Introduction:

Carbon molecular sieve is used as adsorbent for nitrogen production by pressure swing adsorption. Under a certain pressure, the adsorption of oxygen in the air by carbon molecular sieve is much greater than that of nitrogen. Therefore, through the programmable control of the opening and closing of the pneumatic valve, the two towers a and B can alternately cycle, pressure adsorption and decompression desorption to complete the separation of oxygen and nitrogen and obtain the required purity of nitrogen; Reflow soldering oven and wave soldering oven is filled with nitrogen to protect electronic board from oxidation reaction; it is filled with voltage gas in short circuit device, large-scale integrated circuit, color and black-and-white picture tube, TV and recorder parts, as well as the atmosphere for manufacturing protective gas for semiconductor and electrical appliances, laser drilling and other electrical components
