Vacuum inerting is a common procedure used to create an inert atmosphere within a vessel or container.
The process involves drawing a vacuum on the vessel to remove air and other reactive gases.
Then, it replaces the vacuum with an inert gas.
This process is repeated until the desired concentration of inert gas is achieved.
What is Vacuum Inerting? 5 Key Applications Explained
1. Engineering Applications
In engineering, an inert atmosphere can be created by replacing the air within an object or system with other gases that have unique properties.
For example, vacuum wine-saver pumps remove air from wine bottles to reduce oxidation and extend shelf life.
Different gases have different levels of reactivity and oxidation potentials.
Replacing the atmosphere with an inert gas can reduce reaction rates and maintain stability.
2. Food Preservation
In food preservation, inert atmosphere principles are also employed.
Nitrogen injection systems, for instance, can increase the shelf life of perishable goods while preserving their original flavor and texture profiles.
3. Chemical Inactivity
The term "inert" refers to being chemically inactive.
Therefore, an inert atmosphere is an environment in which certain processes can take place without the risk of contamination from reactive gases found in the air, such as oxygen and carbon dioxide.
This is crucial in applications like powder bed fusion, where metal parts are built.
The presence of air molecules can alter the chemical and physical properties of the final components.
Inert atmospheres are used to reduce the risk of contamination and protect against fire and explosions by replacing combustible or reactive gases with non-reactive ones like carbon dioxide or nitrogen.
4. High-Vacuum Environments
Inert atmospheres also have the ability to create a vacuum by replacing the air within a container with an inert gas.
This is particularly useful for creating high-vacuum environments in devices like electron microscopes.
5. Vacuum Sintering
Vacuum sintering is another example of a process that requires an inert atmosphere.
It involves sintering metal or metal compound powder into metal products or blanks at a temperature below the melting point in a vacuum environment.
Sintering under vacuum conditions eliminates reactions between the metal and gas and reduces the influence of adsorbed gas.
This results in good densification, purification, and reduction effects, lower sintering temperatures, energy savings, improved sintering furnace lifespan, and high-quality products.
