Therefore, the diffusion speed of the nitrogen-containing gas in the air is high, and the upward diffusion speed of the nitrogen-containing gas is 2 times that of the nitrogen and 6 times that of natural gas.
Hydrogen has a hydrogen-induced embrittlement effect: due to the characteristics of hydrogen, if some common metal materials are used to store hydrogen, breakage and cracks of the bottle body are easily generated, resulting in leakage of hydrogen. To deal with this problem, need adopt high-pressure resistant plastics and carbon fiber preparation to store the device of hydrogen on the one hand, on the other hand needs install the hydrogen sensor additional, and the very first time sends out the police dispatch newspaper when hydrogen leaks, avoids producing further danger.
