Food grade gas

Position : Index > Food grade gas

Medical oxygen


Description
Oxygen is colorless, odorless and tasteless. It is nonflammable. Almost all materials burn in air, burn much stronger force in oxygen. The atmosphere consists of 20.95 percent oxygen. At temperatures below -184℃ oxygen is in liquid form and has a transparent blue color, and is slightly heavier than water.



Applications
The principal uses of oxygen stems from its strong oxidizing.
1. processing wasted water.
2. food industry.
3. used extensively with in the medical sector, high altitude flying, deep sea diving.
