Seven, helium application
Helium is an element with a large atomic number in the inert gas (that is, a heavier element), and the radius of the helium atom is large. The atomic number 54 and the peripheral electronic arrangement are 5s2 5p6, which are located in the fifth cycle of Group 18 (the new IUPAC regulation, ie the original 0 family), the atomic covalent radius of 209 picometers, and the first ionization energy of 1172 kJ/mol. The elemental substance consists of monoatomic molecules. Rare gas, colorless, odorless, tasteless, density 5.887 kg / m3, melting point -111.9 ° C, boiling point -107.1 ± 3 ° C, soluble at 11 ° C per liter of water at 20 ° C (volume). Can absorb X-rays.
Other aspects: It is used as a combustion improver in combination with flammable gases such as acetylene and propane to achieve the function of welding and cutting metal. It is widely used in various industries, especially in mechanical enterprises. It is also convenient for cutting. It is preferred. A cutting method.
use
Widely used in the electronic and electric light source industries. Compared with an argon-filled bulb of the same power, a bulb filled with helium has the advantages of high luminous efficiency, small volume, long life, and power saving. Because of its fog-permeable ability, it is often used as a foggy navigation light, and is widely used in airports, stations, and terminals. The concave surface of the xenon lamp can generate 2500 ° C high temperature for welding or cutting refractory metals such as titanium and molybdenum. In medicine, sputum is a contrast agent for deep anesthetic X-ray photography without side effects.
System of law
1. Air separation method: extracting krypton and xenon mixture from air separation unit, extracting barren, removing hydrocarbons, carbon dioxide, separating and refining by rectification to obtain 99.99% pure hydrazine.
2. The ruthenium is extracted from the synthetic ammonia tail gas, and the ruthenium and osmium contained in the liquid methane of the methane column in the tail gas argon extraction process can be 95% enthalpy after rectification, washing, deoxidation, adsorption and desorption.
safety
It is a non-combustible gas, dangerous code number: GB 2.2 class 22015. UNNO.2036. IMDG CODE 2188, page 2.2. (Compressed) GB 2.2 Class 22016. UNNO.2591. IMDG CODE 2188 pages, class 2.2. (liquefied). It is protected by a wooden box or carton packed in a 6m3 cylinder or a 2L ampoule. Store in a cool, dry place. High temperature protection. Handle gently during storage and handling, beware of damage to the packaging. Water and various fire extinguishers can be used to save the fire.
Eight, matters needing attention
first-aid
Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Extinguishing method: Keep the container cool with water to prevent it from exploding and causing a rapid fire. Quickly cut off the air source, spray with water to protect the person who cut off the air source, and then choose appropriate fire extinguishing agent to extinguish the fire according to the cause of the fire.
On-site processing
Quickly evacuate people from the contaminated area to the upper reaches, and isolate them, strictly restricting access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear general working clothes. Avoid contact with combustibles or flammable materials. Cut off the source of the leak as much as possible. Proper ventilation and accelerated diffusion. The leaking container should be properly disposed of, repaired, and used after inspection. [15]
Handling and storage
Handling precautions: Closed operation. Closed operation provides good natural ventilation. Operators must be specially trained to strictly follow the operating procedures. Keep away from fire, heat, and smoking in the workplace. Keep away from flammable and combustible materials. Prevent gas from leaking into the workplace air. Avoid contact with the active metal powder. Lightly load and unload during handling to prevent damage to cylinders and accessories. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment.
Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. It should be stored separately from easy (combustible), active metal powder, etc., and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment.
Personal protection
Engineering Control: Closed operation. Provide good natural ventilation.
Body protection: Wear general work clothes.
Hand protection: Wear general working protective gloves.
Other protection: Avoid high concentration inhalation.
