1, liquid nitrogen tank can not be loaded into other low-temperature medium, the container can only be filled with liquid nitrogen, so as to avoid the container itself with the structure of the combustible material caused by the explosion.

 

2, the container should be placed in a cool, dry place, the room should be well ventilated.

 

3, empty mouth with repeatable suction structure, please do not start the user, so as not to affect the cold performance.

 

4, liquid nitrogen temperature of -196 ℃, the operation should be protective measures, such as Dai leather, cotton gloves, etc., do not bare hands. Prevent liquid nitrogen splash, hit the skin or eyes caused by frostbite.

 

5, liquid nitrogen filling: the first container filled with liquid nitrogen and long-term re-filling liquid nitrogen, because the liner is room temperature, filling not too fast, should be a small amount of injection, so that the liner gradually cooling, Liquid nitrogen boiling phenomenon weakened and then accelerate the filling speed. Otherwise liquid nitrogen will be boiling out of the splash, causing frostbite. Liquid nitrogen should not be filled too full, do not make the liquid level to contact with the glass steel neck tube.

 

6, the liquid level check: with a wooden foot into the liquid nitrogen tank container container bottom center, about 10 to 15 seconds after the removal of its frost length is the liquid level. Do not use hollow tube inspection, to prevent liquid nitrogen from the tube spray wounding. The lowest level of liquid can not be lower than the highest surface of cold objects, to ensure that liquid nitrogen will flooded. When the liquid nitrogen to the cold storage will be exposed to the liquid surface, it should be timely replenishment of liquid nitrogen.

 

7, due to storage and storage of diverse ways, the user is equipped with the specifications of our factory, the number of special requirements, can be made in the signing of the contract, so that we arrange production.

 

8, liquid nitrogen tank container can be used for water purification after cleaning, the first row of liquid nitrogen, to restore room temperature and then clean, clean the storage container, pay attention to the water should not be too much (not more than one-third of the volume), so as not to pour sewage When the container is damaged.

 

9, the liquid nitrogen tank containers on the organization, performance, manufacturing quality, service and other aspects of the problem, the use of liquid nitrogen tank containers and liquid nitrogen loss of the law of change, and improve the comments and suggestions please inform me Factory, in order to improve as soon as possible, and better serve the user.
