Calcium peroxide oxygenating agent particles and manufacturing method thereof

Abstract

The invention discloses calcium peroxide oxygenating agent particles. The calcium peroxide oxygenating agent particles comprise the following components in percentage by mass: 60-77 percent of calcium peroxide mixture, 15-25 percent of bentonite, 5-8 percent of polyvinylpolypyrrolidone, 2-5 percent of dry starch and 1-2 percent of benzalkonium bromide, wherein the calcium peroxide mixture contains calcium peroxide and calcium hydroxide, and the percentage composition of calcium peroxide is 65-75 percent. A manufacturing method comprises the following steps: uniformly mixing the calcium peroxide mixture powder, bentonite, polyvinylpolypyrrolidone and the dry starch to obtain an oxygenating agent mixture; adding water and benzalkonium bromide into the oxygenating agent mixture to obtain an oxygenating agent mixed wet material; granulating and polishing the oxygenating agent mixed wet material to obtain the calcium peroxide oxygenating agent particles. The calcium peroxide oxygenating agent particles can quickly sink to the bottom of a pool and can be quickly disintegrated to form calcium peroxide suspension, and then oxygen is gradually released and is absorbed by the water. The manufacturing method has the characteristics of simple process, low production cost and the like.

Description

technical field [0001] The present invention relates to an oxygen-increasing agent and its manufacturing method, more specifically to a calcium peroxide oxygen-increasing particle and its manufacturing method, which belongs to the manufacturing method of inorganic particles. Background technique [0002] Calcium peroxide is a relatively stable peroxide. Calcium peroxide dried at room temperature is not easy to decompose. It has strong bleaching, sterilization and disinfection effects and is non-polluting to the environment. It decomposes slowly in water and releases active oxygen, which is especially suitable for for aquaculture. Calcium peroxide, as an oxygen enhancer in the aquaculture process, can increase the oxygen content of the water body, prevent the death of fish, and at the same time adjust the pH value of the water body, avoid water acidification, reduce the content of ammonia and nitrogen in the water body, remove carbon dioxide, sulfide Toxic and harmful gases ...

AI Technical Summary

Problems solved by technology

[0003] However, the vast majority of calcium peroxide sold on the market is powdery. If the powdery calcium peroxide is put into the breeding pond, the powder will easily float with the wind, and may float into the eyes of the sprinkler, which is very easy to cause harm to the human body. Cause damage, and at the same time, the specific gravity of powdered calcium peroxide is small, and it is not easy to quickly sink into the bottom of the pond, but the specific surface area of ​​the powder in contact with water is large, and oxygen is released quickly, and it is easy to release oxygen on the surface of the water body or before sinking to the bottom. In the end, the oxygen cannot be absorbed by the water body immediately due to the release too fast, resulting in a waste of oxygen, and at the same time, the hydrogen sulfide and carbon dioxide gas at the bottom of the pond cannot be removed, and the effect of calcium peroxide cannot be fully exerted.
