1. 산소 발생 조성물1. Oxygen generating composition
본 발명의 산소 발생 조성물은, 과산화칼슘 2∼20 중량%、탄산칼슘 2∼30 중량%、수산화칼슘 2∼30 중량% 및 인산이수소칼슘 30∼80 중량% 함유하는 성형체로 이루어진다. 한편, 중량%는 산소 발생 조성물을 100 중량%로 한 경우의 중량에 대한 것이다.The oxygen generating composition of the present invention comprises a molded article containing 2 to 20% by weight of calcium peroxide, 2 to 30% by weight of calcium carbonate, 2 to 30% by weight of calcium hydroxide, and 30 to 80% by weight of calcium dihydrogen phosphate. On the other hand, the weight% is based on the weight when the oxygen generating composition is 100% by weight.
본 발명의 산소 방출 성분은 과산화칼슘이다. 과산화칼슘은, 단독으로 물 속에 투입하면 물과 급격하게 반응을 일으켜서, 물 속의 용존산소량이 급격하게 증대하기 때문에, 수질 환경이 급격하게 변화되어 버린다. 그래서, 과산화칼슘에 더해 탄산칼슘 및 수산화칼슘을 상기 범위가 되도록 배합함으로써, 과산화칼슘과 물의 급격한 반응을 억제시킬 수 있다. 그 결과, 과산화칼슘은 물 속에서 안정적으로 반응하고, 장기간에 걸쳐서 서서히 산소 방출을 행하기 때문에, 물 속의 용존산소를 안정적으로 증대시킬 수 있다.The oxygen releasing component of the present invention is calcium peroxide. Calcium peroxide, when added to water alone, causes a rapid reaction with water, and the amount of dissolved oxygen in the water rapidly increases, so that the water quality environment changes rapidly. Therefore, by blending calcium carbonate and calcium hydroxide in the above range in addition to calcium peroxide, a sudden reaction between calcium peroxide and water can be suppressed. As a result, calcium peroxide reacts stably in water and gradually releases oxygen over a long period of time, so that dissolved oxygen in water can be stably increased.
또한, 이것에 인산이수소칼슘을 상기 범위가 되도록 배합함으로써, 산소 발생 조성물을 투입한 물 속의 pH가, 동식물의 생존에 악영향을 끼치지 않는 중성∼산성측으로 유지되어, 안정적인 수질 환경을 유지할 수 있다.In addition, by blending calcium dihydrogen phosphate to the above range, the pH of the water into which the oxygen-generating composition is added is maintained in a neutral to acidic side that does not adversely affect the survival of animals and plants, thereby maintaining a stable water quality environment. .

이상의 실시예 및 비교예에 의해 얻어진 성형체에 관한 평가 결과를 각각 표 1 및 표 2에 나타낸다.The evaluation results of the molded articles obtained by the above Examples and Comparative Examples are shown in Tables 1 and 2, respectively.
실시예의 산소 발생 조성물은, 모두 백탁이 없고, 수질을 급격하게 변화시키지 않으며, 양호한 산소 방출량을 나타내었다.All of the oxygen-generating compositions of the examples had no cloudiness, did not rapidly change the water quality, and exhibited a good amount of oxygen released.
본 발명의 산소 발생 조성물 및 본 발명의 제조방법에 의해 얻어지는 산소 발생 조성물은, 물 속에서 사용되고, 관상어 등의 수생 생물의 양육 환경을 유지하기 위해서 유용하다. 구체적으로는, 관상어용 수조, 활어조용 수조, 활어의 반송용 수조 등의 수조의 물 속에서 산소를 고르게 퍼지게 하여, 백탁이 생기지 않는 안정적인 수질 환경을 유지하기 위해서 유용하다. 특히, 정전시나 관상용 수생 생물이나 활어의 반송시 등, 전원을 필요로 하는 장치를 사용할 수 없고, 물이 순환되지 않는 환경의 경우에 있어서, 특히 수질변화를 싫어하는 송사리, 민물새우 등의 관상어의 양육이나 활어의 반송에 적합한 환경을 유지하기 위해서 유용하다.The oxygen-generating composition of the present invention and the oxygen-generating composition obtained by the production method of the present invention are used in water and are useful in order to maintain an environment for rearing aquatic organisms such as ornamental fish. Specifically, it is useful for maintaining a stable water environment in which no cloudiness occurs by spreading oxygen evenly in the water of a tank such as a tank for ornamental fish, a tank for live fish, and a tank for transporting live fish. In particular, in the case of an environment in which the power supply cannot be used, such as when a power outage or when returning ornamental aquatic organisms or live fish, etc., and in an environment where water is not circulated, the rearing of ornamental fish such as killifish, freshwater shrimp, etc. It is useful to maintain an environment suitable for transporting or live fish.
