What is liquid nitrogen

2020-07-06 17:07:59

       Liquid nitrogen, liquid nitrogen! It is inert, colorless, odorless, non-corrosive, non-flammable, and extremely low temperature. Nitrogen constitutes most of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inactive and does not support combustion. During vaporization, a large amount of endothermic contact causes frostbite; nitrogen accounts for 78% of air. Under normal pressure, the liquid nitrogen temperature is -196°C; 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen at 21°C.
       Liquid nitrogen is a colorless, odorless, low-temperature liquid and gas under high pressure. Liquid nitrogen (often written as LN2) is the liquid form of nitrogen at low temperatures. The boiling point of nitrogen is -196°C. Under normal atmospheric pressure, if the temperature is below this, liquid nitrogen will be formed; if pressurized, liquid nitrogen can be obtained at a higher temperature. In industry, liquid nitrogen is obtained by fractional distillation of air. After purifying the air, it is liquefied under a pressurized and cooled environment and separated by the different boiling points of the components in the air. 

Nuoruida (Tianjin) science and Technology Co., Ltd. is committed to research, development, and sales of liquid nitrogen freezer. Using European technology, we provide a variety of equipment. The main equipment is liquid nitrogen cryogenic freezer, liquid nitrogen cabinet freezer, liquid nitrogen tunnel freezer,sub-zero processing equipment, cryogenic freezing equipment, and so on.
