Nitrogen—Industry salt

1.Nitrogen-filled packaging, nitrogen filling bulbs.Chemical properties (using chemical properties is stable, normal temperature is very difficult to react with other material “) food, canned, fruit and etc.usually use nitrogen for corrosion protection.The nitrogen filling in a light bulb, can prevent the tungsten oxide and slow down the utilization rate of tungsten filament, prolong the bulb’s service life .
2.Chemical synthesis is important raw materials of synthetic fiber (nylon, acrylic), synthetic resin, synthetic rubber and other , also can produce fertilizer.
3.Production car tyres, nitrogen filling tyre can improve the stability and comfort during driving, preventing blowout and grinding line due to deficency , prolong the service life of tires, reduce fuel consumption, protect the environment.
4.Used as shielding gas, normally, Nitrogen’s chemical nature doesn’t very lively, so it is often used as shielding gas.When welding metal with nitrogen,it can protect metal to keep it from oxidation.
5.Nitrogen can be used to protect historical and cultural relics. In the museum, often use to save some valuable and rare page, with gas cylinder full of nitrogen which make the moth smothered.
