Safe use of Liquid Nitrogen Container:
Under normal circumstances, Liquid Nitrogen Container stored in a sealed tank, it should be noted that the Liquid Nitrogen Container tank to retain a certain gap, or Liquid Nitrogen Container gasification can not be timely discharge, easily lead to explosion. General Liquid Nitrogen Container cans have a certain gap in the gap, do not use people in the use of it to block.
Liquid Nitrogen Container use Note:
① Liquid Nitrogen Container is a low temperature products, in the course of the use to prevent frostbite.
② in the Liquid Nitrogen Container operation and access to frozen items faster, pay attention to gently, so as to avoid thawing items, resulting in unnecessary losses.
③ in the use and storage of Liquid Nitrogen Container room, to maintain good ventilation, in order to avoid space hypoxia, resulting in suffocation.
④ because the Liquid Nitrogen Container does not have bactericidal, so contact with Liquid Nitrogen Container appliances should pay attention to disinfection.
⑤ Liquid Nitrogen Container tank in the transport process must be fixed to prevent vibration and upside down.
⑥ Liquid Nitrogen Container tank long-term storage of goods, pay attention to timely replenishment of Liquid Nitrogen Container.
Use of container maintenance:
① in the course of the use of the tank at any time should be checked at any time to check the use of the tank and found the top of the tank or the top of the water droplets and frosting situation, indicating the quality of the tank problems should be immediately stop using; Beads or frosting phenomenon, you can touch the shell by hand, if the upper part of the cold, the lower part of the heat, which also shows the quality of the tank there is a certain problem, that is, the greater the daily increase in Liquid Nitrogen Container should be observed to prevent Liquid Nitrogen Container loss, It is best to stop using the same time in the daily use of the process, but also refer to the relevant pressure vessel safety technical supervision procedures requirements, regular Liquid Nitrogen Container tank and safety equipment, instrument accessories for inspection and verification to ensure its safety and integrity.
② before use to carefully check the container-related safety instruments and accessories, when the instrument, accessories in a good normal state, in order to correctly grasp and adjust the required pressure and capacity; if found outside the hanging cream, should immediately stop using, timely testing And maintenance.
③ Liquid Nitrogen Container tank before filling Liquid Nitrogen Container, first of all to check whether the shell depression, vacuum exhaust port is intact; if damaged, the vacuum will be reduced, serious intake can not heat, so that the upper part of the tank will be knot Frost, Liquid Nitrogen Container loss, will lose the value of continued use; filling Liquid Nitrogen Container can not be Liquid Nitrogen Container in the vacuum exhaust port, so as to avoid the vacuum drop; the same time, filling Liquid Nitrogen Container tank before a small amount of Liquid Nitrogen Container to maintain Pre-cooling state.
④ Liquid Nitrogen Container tank to be stored in a well-ventilated shade, do not sun exposure. Due to its manufacture of precision and inherent characteristics, whether in use or storage, is strictly prohibited Liquid Nitrogen Container tank tilting, horizontal, inverted, stacking, collision or collision with other objects, always keep the tank upright.
⑤ for long-term storage, you need to regularly add Liquid Nitrogen Container, when added, the total amount of Liquid Nitrogen Container should be the total capacity of one-third of the total capacity is appropriate.
⑥ into or out of frozen items, try to make the mouth open time is short, to reduce the consumption of Liquid Nitrogen Container, do not put the barrel completely put forward.
⑦ It is forbidden to place objects and seal the neck on the container cover.
⑧ is strictly prohibited with a hard object to remove the frozen cream within the neck, so as not to damage the neck.
⑨ Liquid Nitrogen Container tank only used to hold Liquid Nitrogen Container, do not allow other liquid or mixed.
