Liquid nitrogen tank product use

The liquid nitrogen tank is manufactured according to the vacuum jacket insulation principle invented by British scientist Dewar in 1898. It scientifically solves the problem of large loss of liquid nitrogen evaporation caused by heat convection, conduction and radiation during storage of liquid nitrogen. With the development of science and technology and the advancement of human society, high-vacuum multi-layer insulation technology and its new materials and new processes have been adopted, so that liquid nitrogen tanks have excellent thermal insulation properties and can be stored in liquid nitrogen (-196 ° C The natural evaporation loss is minimized. Therefore, liquid nitrogen tank products are widely used in animal husbandry, medical and scientific research, mechanical processing, etc., using liquid nitrogen as a refrigerant to preserve animal semen, organs, strains and other organisms. Samples, as well as cryogenic processing of metal materials, cryogenic assembly of precision parts.

Mainly by the following aspects:

1. Activity preservation of animal semen. At present, it is mainly used for the preservation of semen and other rare animals such as cattle and sheep, as well as rare animals (such as giant pandas), as well as long-distance transportation.

2. The active preservation of biological specimens. Vaccines, strains, cells, and organs of humans and animals in the field of biomedicine can be immersed in liquid nitrogen stored in liquid nitrogen tanks for long-term active storage and transportation. When it is needed, take out the thawing and rewarming.

3. Cryogenic treatment of metal materials. The cryogenic treatment of the metal material by the liquid nitrogen stored in the liquid nitrogen tank can change the metallographic structure of the metal material and significantly improve the physical properties such as hardness, strength and wear resistance of the metal material.

4. Cryogenic assembly of precision parts. After the precision parts are cryogenically treated with liquid nitrogen, the assembly quality can be improved, thereby improving the performance of the equipment or the instrument.
