1., the liquid nitrogen tank in use in the presence of frost or ice is normal, we may feel very troubled, and sometimes there will be no leakage of liquid nitrogen. Sometimes it is cooled by the absorption of energy by liquid nitrogen vaporization, condensation of water vapor in the air. If there is no use, the temperature is not very low, and there is frost or ice, which may be a leakage of liquid nitrogen. A new liquid nitrogen tank is recommended, and the liquid nitrogen tank has a longer storage time and is not easy to leak.

2., there are many reasons for the freezing of liquid nitrogen tanks. For example, sometimes there are some problems with the tank insulation. A liquid nitrogen tank insulation perlite insulation, vacuum powder insulation, if perlite insulation can check with the adequacy of perlite and sandwich seal gas is to ensure the micro positive pressure; the vacuum degree of vacuum powder insulation whether meet the requirements. The problem of heat preservation is solved, and the ice on the tank will melt and fall naturally.

Therefore, in the process of using liquid nitrogen tanks, we should pay attention to some problems, so that we can better use this product.
