Uses of helium What are the uses of helium?

1, helium uses of aerospace: ultra-pure helium such as 6N helium in rockets, spacecraft used as the delivery of liquid hydrogen, liquid oxygen and other liquid propellants pressurized gas. In the aerospace and aircraft manufacturing industries, helium is used to purify hydrogen systems for space flight operations and as a pressurizer for ground and flight fluid systems throughout the entire process from manufacturing to flight. In addition to this, helium is used as a source of lift for meteorological and other observation balloons.

2, helium uses of transportation and transportation equipment: Because helium is the gas with the lowest boiling point in the world, and has exceptionally good thermal conductivity, it is widely used in the testing of important automotive components, such as radiator exchangers, air conditioning components, fuel tanks, and torque converters, to ensure that they comply with quality specifications. In addition, helium can be used in conjunction with argon and is increasingly used in airbag inflation operations.

3, the use of helium entertainment and decoration: helium voice performance we should have heard of, after inhaling helium, because helium spreads sound almost three times as fast as air, people inhale helium gas, the frequency of the voice will become higher, so that people can imitate the soprano singers, but also can be called to speak shrill, as if the cartoon characters of the old days. However, helium is also an asphyxiating gas, and it is easy to inhale too much helium without professional supervision, leading to asphyxiation and death! Recently, there are a lot of news related to helium voice change, for example, Hollywood veteran black actor_Morgan_Riemann utilized the helium voice change method and changed his voice in 3 seconds to have a Donald Duck accent. Another example is the famous footballer Balotelli who shouted Liverpool in an extremely funny tone of voice after sucking helium not long ago.

4, helium use of health care: helium-neon laser can be used for surgery, can also be used to treat amblyopia, can also be used to activate blood vessels for health care. The gas medium in helium-neon laser is neon gas and high-purity helium. In addition due to the low temperature superconductivity of helium, it is the ideal freezing gas to be used as a superconducting magnet for magnetic *** vibration and nuclear magnetic *** vibration. Helium can achieve deep cold temperatures of -451 degrees Fahrenheit, effectively acquiring high resolution images of internal organs and tissues.

5, helium use of electronic research: helium in the semiconductor, liquid crystal panels and fiber optic line manufacturing plays an important role in the rapid cooling of parts to improve productivity, but also to control the rate of heat transfer to improve productivity and reduce defects; In addition, helium can also be used as a carrier gas in the production process, high-purity helium used as a gas chromatography/gas chromatography and other instrumentation. High purity helium is used as a carrier gas for instruments such as gas chromatographs/gas chromatography.

6, helium use of welding and metal processing: high purity helium and high purity argon together as a special welding shielding gas. Helium's inertness at arc temperature makes it an ideal gas for welding aluminum, stainless steel, copper and magnesium alloys with high thermal conductivity. It can also be used as a quenching gas in the heat treatment process as well as a furnace gas to enhance the resistance and quality of parts.

7, the use of helium diving gas: deep-water diving tanks must be filled with oxygen and helium. Helium is not prone to deep-sea paralysis, helium is used to replace nitrogen in deep-sea diving.
