The simplest application unit of the nitrogen generator with pressure swing adsorption technology is composed of two adsorption towers filled with carbon molecular sieve, gas inlet and outlet pipelines, PLC, programmable valves, analysis and field instruments. When compressed air enters from the inlet and flows through the adsorbent (carbon molecular sieve) in the adsorption tower, the oxygen molecules in the compressed air are adsorbed, while the unadsorbed nitrogen molecules are enriched and flow out from the outlet; When the carbon molecular sieve is saturated with adsorption, close the inlet valve and the outlet valve, and open the exhaust valve to desorb the adsorbent. After the regeneration gas is completely regenerated, it will be used in the next adsorption cycle.

There are two main sources of nitrogen: liquid canned nitrogen, nitrogen generator is used to generate nitrogen (extract nitrogen directly from the total air).
2018-11-05Why should SMT introduce lead-free soldering
Lead is a toxic heavy metal. Excessive absorption of lead in the human body can cause poisoning, and low intake of lead may affect the human intelligence, nervous system and reproductive system. The global electronic assembly industry consumes about 60,000 tons of solder each year, and it is increasing year by year. The resulting industrial scum containing lead salts seriously pollutes the environment, so reducing the use of lead has become the focus of worldwide attention. Many large companies in Europe, Japan, South Korea, etc. are vigorously accelerating the development of lead-free alternative alloys, and have planned to gradually reduce the use of lead in electronic product assembly in 2002. (The traditional solder composition contains 63Sn/37Pb, and lead is widely used in the current electronic assembly industry). The European Union began to introduce lead-free technology in 2006, and from July 1st it banned lead in electronic products. The development of lead-free technology in the electronic complete machine industry is an inevitable trend in the development of the international information industry. my country’s Ministry of Information Industry also requires the country to achieve lead-free electronic information products before July 1, 2006.
2018-11-05What advanced technology does the PSA nitrogen generator use?
The advanced nature of PSA nitrogen generator Low cost: P.S.A. advanced technology is a simple nitrogen production method, which produces nitrogen within a few minutes after starting up, and has low energy consumption. The cost of nitrogen is lower than that of cryogenic air separation. Reliable performance: imported microcomputer control, fully automatic operation, no need for special training operators, just press the start switch, it can run automatically to achieve continuous nitrogen production.
