いる。<Problems to be Solved by the Invention> However, when this type of oxygen generating agent is filled into a bag and thrown into water, the pH of the oxygen generator decreases during the reaction process, which has a negative effect on fish. In particular, citric acid has high solubility in water,
Since a large amount is dissolved into water before reacting with peroxide, the degree of water contamination becomes significant. Furthermore, citric acid is expensive, which is a factor that increases the manufacturing cost of oxygen generating agents.

溶は出す量が少なく、水の汚染度合も小さい。<Function> When the oxygen generating agent according to the invention of claim 1 filled in a storage bag is thrown into water, the alkaline earth metal peroxide and fumaric acid react to generate oxygen, but the reaction does not occur. The inhibitor suppresses premature reaction and maintains the generation of the appropriate amount of oxygen for a long period of time. Furthermore, since fumaric acid does not have a high solubility in water like citric acid, the amount dissolved in water before the reaction is small, and the degree of water contamination is also small.

ると共に、酸素発生剤１の浮上がりを防止している。Next, the above-mentioned storage bag 2 is made of high shrinkage vinylon fiber cloth and is formed into a bag-like structure with an inner and outer double layer structure. This high-shrinkage vinylon fiber has the property of shrinking when wet, and when the oxygen generating agent 1 is put into water, the high-shrinkage vinylon fiber shrinks, thereby expelling the air inside the storage bag 2 to the outside. Extrude oxygen generating agent 1
The particles are brought into close contact with each other, thereby appropriately adjusting the reaction rate and preventing the oxygen generating agent 1 from floating up.

素を発生する。When the illustrated example is put into water, the highly shrinkable vinylon fibers of the storage bag 2 contract in a short time, strongly tightening the oxygen generating agent 1 inside. As a result, the air inside the storage bag 2 is pushed out and the entire bag sinks to the bottom of the water, and in this state, the calcium peroxide and fumaric acid of the oxygen generating agent 1 react to generate oxygen.

When a reaction accelerator is used, the reaction accelerator accelerates the reaction between the peroxide and fumaric acid, increasing the amount of oxygen generated while maintaining the sustainability of oxygen generation.

素発生剤を製造コストを低減できる。<Effects of the Invention> As described above, the present invention uses a mixture of an alkaline earth metal peroxide, fumaric acid, and a reaction inhibitor that suppresses the reaction between the peroxide and fumaric acid as an oxygen generating agent. Since it is the main ingredient, the reaction inhibitor suppresses the premature reaction between peroxide and fumaric acid, achieving the generation of an appropriate amount of oxygen over a long period of time. Moreover, since fumaric acid does not have a high solubility in water like citric acid, it is less likely to be dissolved into water before the reaction and contaminate the water.Furthermore, fumaric acid can be obtained at low cost, making it easy to manufacture oxygen generators at low cost. can be reduced.

This provides remarkable effects, such as allowing the amount of oxygen generated and the sustainability of oxygen generation to be set at will.
