【Product name】Liquid oxygen, also known as liquid oxygen.

【Product overview】According to the "List of Hazardous Chemicals" issued by the State Council, liquid oxygen belongs to Class 2.2 compressed gases and liquefied gases, which are non flammable and non-toxic gases.

【Product characteristics】Colorless and odorless gas. Melting point -218.4 ℃, boiling point -183 ℃. Not easily soluble in water.

Liquid oxygen appears light blue, and due to its low temperature characteristics, liquid oxygen makes the substances it comes into contact with very fragile.

Liquid oxygen is a very strong oxidant, and organic matter can burn violently in liquid oxygen.

Liquid oxygen has strong oxidizing properties and reacts with metals to form metal oxides; Reacting with non-metallic substances to generate non-metallic oxides.

In addition, liquid oxygen can also undergo oxidation reactions with organic compounds to produce carbon dioxide and water.

【Application area 】

Aerospace field: Liquid oxygen, as a fuel for rocket engines, is an indispensable and important component of modern aerospace industry. Liquid oxygen not only has high storage density, but also the oxygen emitted after combustion is the source of oxygen needed for astronaut survival. In addition, liquid oxygen can also be used for propellants, attitude control, and manipulation systems.

In the field of chemical industry, liquid oxygen is commonly used as an oxidant, such as in the desulfurization process of oil refining. By using liquid oxygen oxidant, the sulfur content can be reduced and air pollution can be minimized. In addition, liquid oxygen is widely used as an oxidant or oxygen source in industries such as rubber, plastics, and coatings.

Medical field: mainly used for medical oxygen production, which separates nitrogen from the air to provide the oxygen needed by the body. Liquid oxygen oxygen production equipment is widely used in hospitals, emergency vehicles, nursing stations and other institutions. In the treatment of respiratory system diseases, oxygen production equipment also plays a crucial role.

Environmental protection field: becoming increasingly widespread. For example, in exhaust gas treatment systems, liquid oxygen can not only provide oxygen to promote the oxidation and decomposition of harmful components in exhaust gas, but also work together with NOx reducing agents to reduce the emission concentration of NOx.

【Usage and precautions】

Sealed operation, providing good natural ventilation conditions.

Operators must strictly follow the operating procedures to prevent gas leakage into the workplace air.

Equip with emergency response equipment for leaks.

High pressure gas cylinders for storing gases should be used according to regulations.

【Packaging and storage】

Bottled gas products should be classified and stacked during transportation, storage, and use. Combustible gases and combustion supporting gases should not be stacked together, and they should not be placed near open flames or heat sources. They should be kept away from fire, oil and wax, exposure to sunlight, heavy throwing, or impact. Arc ignition or arcing on gas cylinders is strictly prohibited, and rough loading and unloading are strictly prohibited.
