คำอธิบายของก๊าซ
Oxygen, chemical formula O2. Chemical formula quantity: 32.00, colorless and odorless gas, the most common elemental form of oxygen element. Melting point -218.4 ℃, boiling point -183 ℃. Not easily soluble in water, about 30mL of oxygen is dissolved in 1L of water. Oxygen accounts for approximately 21% in the air. Liquid oxygen is sky blue. Solid oxygen is a blue crystal. Not very active at room temperature and not easily interacting with many substances. But at high temperatures, it is very active and can directly combine with various elements, which is related to the electronegativity of oxygen atoms, second only to fluorine.
Oxygen is the most widely distributed element in nature, accounting for 48.6% of the Earth's crust mass, and is the most abundant element. Oxygen is required for the oxidation of hydrocarbons, treatment of wastewater, rocket propellants, as well as for animal and human respiration in aviation, aerospace, and diving. Animal respiration, combustion, and all oxidation processes (including organic decay) consume oxygen. But oxygen in the air can be continuously replenished through plant photosynthesis. 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 with extremely high temperature, thereby melting the metal. The metallurgical process cannot do without oxygen. In order to strengthen the production process of nitric acid and sulfuric acid, oxygen is also required. Blowing a mixture of oxygen and water vapor into a gas gasifier without using air can produce high calorific value gas. Medical gas is extremely important.
การประยุกต์ใช้ผลิตภัณฑ์
Smelting process: During the steelmaking process, high-purity oxygen is blown, which reacts with carbon, phosphorus, sulfur, silicon, etc. to oxidize. This not only reduces the carbon content of the steel, but also helps to remove impurities such as phosphorus, sulfur, and silicon. Moreover, the heat generated during the oxidation process is sufficient to maintain the temperature required for the steelmaking process. Therefore, oxygen blowing not only shortens the smelting time, but also improves the quality of the steel. During blast furnace ironmaking, increasing the oxygen concentration in the blast can reduce the coke ratio and increase production. In non-ferrous metal smelting, the use of enriched oxygen can also shorten smelting time and increase production.
Chemical industry: In the production of synthetic ammonia, oxygen is mainly used for the oxidation of feed gas to strengthen the process and increase fertilizer yield. For example, high-temperature cracking of heavy oil and gasification of coal powder.
National Defense Industry: Liquid oxygen is the best combustion aid for modern rockets, and it is also needed as an oxidizer in supersonic aircraft. Combustible materials impregnated with liquid oxygen have strong explosiveness and can be used to produce liquid oxygen explosives.
Healthcare: Supply breathing: Used in hypoxic, hypoxic or anaerobic environments, such as diving, mountaineering, high-altitude flight, space navigation, medical rescue, etc.
Other aspects: It is used as a combustion aid in combination with combustible gases such as acetylene and propane to achieve the function of welding and cutting metals. It is widely used in various industries, especially in mechanical enterprises, and is also very convenient for cutting. It is the preferred cutting method.
