Liquid nitrogen is derived from air. It is a liquid compressed and cooled by nitrogen. It has special physical and chemical properties. It is colorless, odorless, and non-toxic. It has the characteristics of ultra-low temperature and volatile expansion.
When liquid nitrogen needs to be transported, liquid nitrogen needs to be stored in a professional low-temperature container liquid nitrogen tank, and must ensure normal air circulation in the car box, do not put these devices in closed vehicles, in these vehicles, liquid nitrogen Nitrogen will be continuously discharged from the liquid nitrogen tank. Nitrogen will quickly accumulate and occupy the oxygen content in the air. It is easy to cause suffocation.
Note: During transportation, the liquid nitrogen tank must be installed in a wooden frame with a soft pad and fixed. The tanks and tanks should be separated by fillers to prevent bumps and bumps and prevent dumping. When loading and unloading the truck, the liquid nitrogen tank must be strictly prevented from hitting, and it can not be dragged on the ground at will, so as not to reduce the service life of the liquid nitrogen tank.
