【Product name】Liquid argon, also known as argon.

【Product overview】According to the List of Hazardous Chemicals, liquid argon belongs to Class 2.2 non combustible gas and has specific hazard categories.

【Product characteristics】Colorless, odorless, and tasteless liquid. The boiling point range is -185.7 ℃ to -189.2 ℃, and the melting point range is -189.2 ℃ to -185.9 ℃. The density of liquid argon is higher than that of air, about 1.4 times that of air. It is an excellent inert gas that does not undergo chemical reactions with other elements or compounds.

Argon is an inert gas, which means it does not undergo chemical reactions with other elements or compounds. Therefore, it is used as a protective gas in many chemical reactions. For example, during the welding process, argon can protect the melted metal, reduce the generation of smoke, and make the welding process more stable.

【Application area 】

Metallurgical industry: Due to its excellent conductivity and thermal conductivity in the gaseous state, liquid argon is widely used in the field of welding, acting on metal cutting and welding. The gas purity used for liquid argon gas welding is very high, which can protect the molten metal during the welding process and avoid adverse phenomena such as oxidation, pollution, and bubbles. Meanwhile, liquid argon can also ensure a relatively stable temperature at the welding site, avoiding welding defects caused by temperature changes.

Cryopreservation industry: Due to the extremely low boiling point of liquid argon, it can be used to create ultra-low temperature environments and can be used for cryopreservation of various substances, such as food, drugs, biological specimens, etc. In the field of space food and scientific research for astronauts, liquid argon can be used to ensure that food and specimens are stored for a long time without deformation or decay.

In the field of superconducting electronics, superconductors refer to substances that have zero resistance at low temperatures and possess excellent conductivity and magnetism. Liquid argon is widely used in the manufacturing and research of various superconducting materials and devices used in the field of superconducting electronics. Liquid argon can provide very low temperatures for superconducting materials to ensure their good working performance and long-term service life.

Medical and health industry: Liquid argon can be used to cool medical equipment, such as nuclear magnetic resonance machines, to ensure the normal operation and accurate diagnosis of medical equipment. Meanwhile, liquid argon can also be used to treat certain skin diseases and conditions such as sinusitis caused by rheumatoid arthritis.

【Usage and precautions】

The container for storing liquid argon should be sealed to prevent leakage.

Before use, ensure good ventilation in the workplace to avoid harm to human health caused by high concentration liquid argon.

Operators need to undergo professional training to understand the physical and chemical properties of liquid argon and the correct usage methods.

【Packaging and storage】

When handling liquid argon, it is important to handle with care and avoid dangerous factors such as static electricity and sparks during loading and unloading.

For discarded liquid argon, it is necessary to handle it properly according to relevant regulations to avoid polluting the environment.
