Description
Principles
N2 and O2 all have a quadrupole, for the reason that the quadrupole of N2(0.31 Å)is bigger than the quadrupole of O2 (0.10 Å), the adsorption capacity by molecular sieve to N2 is stronger than O2. When the compressed air in certain pressure flow through adsorption bed formed by molecular sieve, the N2 gas is absorbed and O2 is obtained by separation.
The main part of N2 generator is two towers filled with molecular sieve , when the compressed air get into adsorption tower, the N2, is absorbed by molecular sieve, N2 is produced from the export terminal . When one tower produces N2, another tower release the N2 by reducing the pressure to get the renewable desorption of carbon molecular sieve. Two towers alternate adsorption and regeneration to output N2 continuously.
Application Overviews
In the reflow soldering of SMT, nitrogen gas is charged into reflow furnace.The following advantages of soldering are listed in the nitrogen atmosphere:
.The quality of soldering is enhanced with the prevention of surface oxidation.
.The flux is guaranteed to the correct activation.
.The surface of soldering is more handsome.
Characteristics
. High purity, and the purity of N2 could be regulated between 95% to 99.999% according as user's need;
.High efficiency, low energy consumption of compressed air;
.Standard models, nitrogen generator could be parallel for additional nitrogen output;
.Low dew point, dew point of product ≤ -40 °C to ensure the quality of welding;
.Available frame, appearance clean and easy cleaning management to meet the high cleanliness requirement of electronics industry.
Freight situation
The workers more carefully to the packaging of the nitrogen generator has been shipped on freight car.
