What is canned air?

Preserved air is supplied in a pressure vessel used to clean sensitive electronic devices such as stereos and computers. The canister content is under such an extreme pressure that it has become a liquid, but the narrow nozzle directs the released gas to a strong air stream. Air blows dust and remnants of small places such as the spaces between the keyboard keys. Because canned air has no humidity, added chemicals or foreign particles, it is a safe and effective way of cleaning such devices. For example, the interior of computers, especially around the fan, can build so much dust that it starts to interfere with cooling or functioning of circuits. The particles are held on surfaces such as lenses, film negatives and enlarged, but you cannot use a fabric or feathers-pipe to scratch them. Electric components cannot be sprayed with dust chemicals because they could damage the circuit or build excess static electricity.

The canned air was designed specifically for cleaning places that cannot be cleaned with a vacuum, dust -fabric or ammonia -based spray cleaner. Its content contains absolutely no humidity, so when cleaning it does not dampen your printer, scanner, camera, glasses, keyboard, monitor or hard drive. Although it is true that canned air just spray the dust back into the air, where it can re -relocate, has the advantage over vacuums because it does not create a static charge.

You may be afraid that if the atmosphere is more polluting, we all pay for life from canned air. However, this useful product is not like the air we breathe at all. Previously, it contained chlorofluorocarbones as many pressure canisters, such as hair hair. After it has been shown that these gases have damaged the Ozonv atmosphere, most companies have removed them from canned air. Now the mixture is often made up of many nitrogen, along with other harmless gases heavier than a voiceEar, so they will be marked with "safe ozone".

non -articulated containers look like small cans of oil lubricant. The content comes with a long, cylindrical nozzle when you press the valve with an index finger. The content is non -flammable. It is possible that enough gas could push oxygen in one area and cause lightness, so make sure you work with adequate circulation. Cansters are no longer allowed on aircraft.

Another interesting aspect of canned air is its adiabatic cooling property. When the gas is below such high pressure, approximately 70 dogs, the release of pressure causes a remarkable temperature drop. You may notice that the surrounding air and the canister itself will cool down during use. A rapid expansion of the gas, which previously occupied a small space into a large space, is absorbed by a lot of heat from the area when spreading. For this reason, never take canned air on the skin as it can quickly cause frostbite.
