Hermetic seals prevent the entry of oxygen, moisture, and contaminants in various industries. They are used in building, food packaging, air travel, deep sea diving, and telecommunications to maintain a comfortable environment and prevent corrosion or breakage.
Hermetic seals are hermetic seals that prevent the entry of oxygen, moisture, moisture and any external contaminants into a sealed environment. The concept is found in the building industry, where the double-glazed windows that are used in both domestic and office construction rely on the presence of the hermetic seal to prevent any type of moisture or contaminants from infiltrating between the two panes of glass . These windows facilitate climate control within the building space. In the event of gasket failure, there is generally a misting effect between the panes, a clear sign that the panes are no longer able to perform their function and must be replaced immediately.
The hermetic closure is also often found in the food industry. Many companies have started using them in packaging as a way to keep foods fresh without the need for a lot of preservatives. A good example of this type of airtight packaging is the reinforced foil packs used with tuna and salmon. Until the consumer opens the package, the contents remain fresh and usable for long periods and do not require some of the additives that lower the nutritional value of the product.
Air travel and deep sea diving would be impossible without the presence of an airtight seal. The airtight seal helps maintain a comfortable pressure and oxygen level inside an aircraft for everyone on board. With undersea exploration, seals on all inlets to a submarine or bathysphere keep water out and oxygen in, while also helping to keep pressure at a level acceptable to human life. They also mean planes can fly higher and faster and marine biologists can explore more of the ocean than ever before.
They are also used in the telecommunications sector. Fiber cables use airtight seals to keep out moisture and moisture that could over time corrode and weaken the individual fibers that process telephone signals. Likewise, cable companies will use the same strategy, ensuring that cable, Internet and telephone service to their customer base remains consistent. Seals on telecommunication cables allow the cable to be securely suspended at electrical poles or buried, without worries of corrosion or breakage due to weather and climate conditions.
