Summary of Nitrogen uses -- fruits and vegetables, metals

In the process of storage and transportation of fresh fruits and vegetables, etc., when the temperature is adjusted to the best refrigeration temperature suitable for the storage, the respiration rate of the storage will decrease, but it will still breathe, and some substances that can cause chemical changes will still produce chemical changes... How do we do that? The nitrogen machine. After repeated practice, it has been proved that the storage tank is filled with nitrogen to balance carbon dioxide, oxygen, etc., and the storage is almost free of these phenomena. In comparison, the shelf life of nitrogen-filled storage is at least 10 months longer than that of non-nitrogen-filled storage. For apples, bananas, pears, oranges and other perishable fruits, nitrogen storage effect is particularly significant. Compared with the economic benefits and social effects brought by the use of chemical preservatives, it is extraordinary. At present, this method has been adopted by many manufacturers, businesses and farmers at home and abroad. Nitriding of nitrogen in metal; Nitrogen protection during cable production; Electronic products, medicine, petrochemical and other applications are everywhere!
