Seven, helium application
An inert gas that is gaseous at normal temperature, does not burn, and does not support combustion. When performing a low voltage discharge, a very pronounced emission line is shown in the red portion. Very inactive, not burning, nor burning. Liquid helium has the advantages of low boiling point, high latent heat of vaporization, and safe use.
1. For neon lights and as a filling medium for the electronics industry (eg high-voltage xenon lamps, counter tubes, etc.);
2. For laser technology, do the illuminating indicator light, voltage regulation, and laser gas mixture;
3. A helium-oxygen mixture replaces helium oxygen for breathing;
4. Used as low temperature coolant, standard gas, special gas mixture, etc.
5. For high-energy physics research, let the sputum fill the spark chamber to detect and the path of the particles;
Eight, matters needing attention
Risk
At high concentrations, this product can reduce the partial pressure of oxygen in the air and pose a choking hazard. The table has accelerated breathing, inattention, and ataxia; followed by fatigue, irritability, nausea, vomiting, coma, convulsions, and death. No special protection is required for production. However, when the oxygen concentration in the workplace air is less than 18%, an air respirator, oxygen respirator or long tube mask must be worn.
Storage and transportation
1. Transportation precautions: Non-corrosive, general materials can be used. Austenitic stainless steel can be used for liquid helium.Generally stored in glass or steel bottles. During storage and transportation, it should be lightly loaded and unloaded to prevent the container from being damaged. The liquid helium production is small, and it can be stored and transported in a liquid helium container similar to a small liquid nitrogen screen type. When such a container is used, the support of its contents must be reinforced to accommodate the greater density of liquid helium;
2. Storage precautions: warehouse ventilation and low temperature drying; light loading and unloading
