Product Description
Magnesium peroxide is white or slightly yellow powder, odorless and tasteless, hardly soluble in water, but easily soluble in acid. Magnesium peroxide is a very stable peroxide. It is not easy to decompose at room temperature. It begins to decompose at 350°C. It can slowly release oxygen for a long time in humid air or water. Magnesium peroxide has strong bleaching, sterilizing, and disinfecting effects, and is harmless to the environment.
Applications
This product is a multifunctional inorganic peroxide with wide application. Compared with other peroxides such as calcium peroxide and coated sodium percarbonate, magnesium peroxide has a longer dilution period, a smaller pH value conversion range and a higher release per unit area, so it is very suitable for soil biological improvement and groundwater treatment. In terms of agricultural planting, magnesium peroxide is used to supply oxygen to plant roots, coat rice seeds, make oxygen fertilizer and biological compound fertilizer, etc.; in aquaculture, it can be used as an oxygen release agent to increase dissolved oxygen in water, adjust the pH value of water, improve Water quality, elimination of pathogenic bacteria, etc.; in addition, magnesium peroxide is also used in tooth bleaching agents, hair dyes, etc.
Packaging and Storage
Inner: 25Kg/bag, lined with polyethylene thin outer: plastic woven bag
Storage: Store in a dry, clean, well-ventilated warehouse. Keep away from fire, heat sources and direct sunlight. Do not mix with flammable or combustible materials, reducing agents, etc. Pay attention to moisture and rain.
What is magnesium peroxide generally used for in life?
Magnesium peroxide has the characteristics of long oxygen release time, safety, convenient use and low price, and is a stable inorganic peroxide. Magnesium peroxide is being widely used in environmental protection, soil improvement, and sewage sludge treatment industries. The following is a brief analysis of the use and application fields of MgO2.
1. Create an aerobic environment to stimulate oil-loving microorganisms to degrade petroleum pollutants into carbon dioxide and water under aerobic conditions. MgO2 has no potential negative effects on aquifers, and the by-products of the reaction with water are oxygen and commonly magnesium hydroxide, which is essentially insoluble.
2. In the chemical treatment process of oil and gas wells such as shale gas development, it is used to clean and extract viscous gel breakers similar to filter cakes. In oil pollution control, the effect of using magnesium peroxide is remarkable. Accelerate the biodegradation rate of pollutants; control the plume pollution of groundwater; magnesium peroxide is used as a one-step purification process to achieve the expected level of pollutant recovery; MgO2 can be mixed with other injection biological treatment products, directly in the storage Nutrients or microorganisms are added to the aqueous layer.
3. MgO2 can release oxygen stably, which is suitable for agriculture or environment-related industries, such as reducing the content of groundwater pollutants.
4. MgO2 is also used to restore polluted soil and improve plant growth and metabolism. Adding it to compost can promote the activity of microorganisms, and at the same time reduce the odor of compost.
5. Since MgO2 first generates highly active oxygen atoms when it decomposes, it has strong oxidation, disinfection, bleaching, etc., and has certain destructive and anti-fermentation effects, so it is often used as an antacid in medicine , anti-fermentation effect, treatment of indigestion, hyperacidity, constipation, abdominal distension, abnormal intestinal fermentation and other diseases.
6. MgO2 can also inhibit the growth of sulfate-reducing bacteria, which may be because slowly decomposed peroxide ions replace sulfate ions to obtain electrons in the electron transport chain of the reaction. It can also be used in cosmetics and water disinfectants, bleaching agents, etc., and has similar functions to other peroxides. Magnesium peroxide MgO2 can exist stably for a long time. The total release period of oxygen will last for 2-10 months, but the conditions in different places are different, mainly determined by the amount of pollutants and the flow rate of groundwater. Field tests have shown that magnesium compounds can continuously release oxygen for at least 6 months in most hydrocarbon-contaminated groundwater.
