Pressure swing adsorption (PSA nitrogen generator is one kind of physical process which is safe, easy and power saving. From the compressed air which is content of 79% nitrogen is the source of nitrogen generator, for this situation, it can be produced 99.9999% purity of nitrogen by PSA technology, The theory is that when the compressed air goes through the sieve material, the oxygen will be adsorbed under the pressure and collect the nitrogen, so when the pressure is released, the oxygen will be out, so it can produce nitrogen continually.
1.1 SMT Filed
For this filed normally it uses in reflow and wave soldering, nitrogen can restrict the oxidation of the solder tin, improve the wettability of solder, speed up the solder ball , avoid the bridge, decrease the faulty and finally get the good quality of soldering.
In this filed nitrogen will be used for soldering (if necessary), blow and packaging.
1.3.Metallurgy and metal field
It normally uses in Heat treatment like the steel, iron, copper and aluminum which process is anneal, carbonization, the protection in high temperature, the assemble in low temperature and plasma cutting ETC.
1.4 Food and medical filed
It mainly uses in food package, fresh, storage, dry and sterilization; medical package, air exchange, and medicine delivery and etc..
1.5 Petroleum and gas filed
It uses for the exploiting of petroleum and gas in land, and it is also the key element for delivering, covering, exchanging, maintenance and etc in the exploiting of sea petroleum and gas.
Except the filed above, it also can use more field like mineral, molding injection, tire process and charge and etc.
