Industrial Gas
Key words:
Argon (Ar) is a colorless, odorless, and non-toxic inert gas with a relative atomic mass of 39.948. It is one of the components of air and is mainly produced through air liquefaction and distillation. Argon gas has stable chemical properties and is not easily reactive with other substances, so it has a wide range of applications in industry, such as being used as a welding shielding gas, bulb inflation, low-temperature freezing, photolithography process in semiconductor manufacturing, and inert atmosphere in scientific research experiments. In addition, argon gas has a density 1.4 times that of air at room temperature and is slightly soluble in water.
Key words:
Oxygen (O₂) is an important component of the Earth's atmosphere, accounting for approximately 21% of the air volume and being the most abundant element. Oxygen is required for the oxidation of hydrocarbons, treatment of wastewater, rocket propellants, and for respiration of animals and humans in aviation, aerospace, and diving. Animal respiration, combustion, and all oxidation processes (including the decay of organic compounds) consume oxygen. But oxygen in the air can be continuously replenished through the photosynthesis of plants. In the cutting and welding of metals. It is a mixture of oxygen with a purity of 93.5%~99.2% and combustible gas (such as acetylene) to produce a flame at extremely high temperatures, thereby melting the metal. The metallurgical process cannot do without oxygen. Oxygen is also required to enhance the production process of nitric acid and sulfuric acid. By blowing a mixture of oxygen and water vapor into a gasifier without using air, high calorific value gas can be obtained. Medical gas is extremely important.
