Abstract

The invention discloses an oxygen-absorbing and oxygen-releasing agent prepared by mixing one or more of ferrous oxide, cobaltous oxide, ferrous naphthoate, cobaltous naphthoate, ferrous acetate and cobaltous acetate. The oxygen-absorbing and oxygen-releasing agent absorbs oxygen in a room temperature atmospheric environment, releases oxygen when the partial pressure of ambient oxygen is lower than the partial pressure of oxygen in air or greater than the partial pressure at the temperature of 80 DEG C, and then absorbs oxygen at the room temperature atmospheric environment after releasing oxygen. The oxygen-absorbing and oxygen-releasing agent has the functions of oxygen absorption and oxygen release repeated recycling, and is suitable for food, hygiene, medical treatment, military and many fields.

Description

technical field [0001] The invention relates to the technical field of oxygen absorbing and releasing oxygen storage, in particular to an oxygen absorbing and releasing agent. Background technique [0002] In the medical field, the delivery of oxygen depends on oxygen cylinders or oxygen bag bottles, which are bulky and heavy, and are not conducive to carrying. [0003] In the food industry, it has been widely used to keep food fresh by absorbing oxygen in the air. However, this one-time use method creates a lot of waste. [0004] In aviation, aerospace, navigation and other military and civilian fields, due to the limited space for carrying objects, the equipped oxygen supply equipment is large in size, limited in space, and low in storage capacity, which greatly limits the efficiency of oxygen use. [0005] Other industries and fields that use oxygen have the confusion of being difficult to reduce the weight of oxygen cylinders and increasing the amount of oxygen carried...
