Activated magnesium oxide refers to magnesium oxide with higher surface area and activity, smaller particle size and strong adsorption capacity. It has a wide range of application areas, such as catalysts, adsorption agents, fillers, refractory materials, etc.
There are mainly the preparation methods for active magnesium oxide:
Burning method: natural magnesium minerals, such as diamonds, white clouds, magnesium olives, etc. at high temperatures, burn down and decompose to obtain magnesium oxide. The higher the burning temperature, the lower the activity of magnesium oxide.
Settlement method: The soluble magnesium salt solution, such as magnesium chloride, magnesium sulfate, etc., adds to the alkali solution, precipitate magnesium hydroxide, and then burns magnesium oxide. The magnesium oxide prepared by the precipitation method has high activity.
Legal water: The soluble magnesium salt solution, such as magnesium chloride, magnesium sulfate, etc., hydrolyze in the aqueous solution, generate magnesium hydroxide, and then burns magnesium oxide. Magnesium oxide prepared by water has high purity and activity.
Solvent thermal method: Under high pressure and high temperature conditions, use organic solvents or water solvents as reaction medium, react with magnesium salt with alkali or other reagents to directly synthesize magnesium oxide. Magnesium oxide prepared by solvent thermal method has a small particle size and high activity.
Activated magnesium oxide can be classified according to its preparation methods, particle size, activity and other indicators.
Classified by preparation methods: It can be divided into magnesium oxide, magnesium oxide oxide, magnesium oxide, magnesium oxide and solvents thermal activity magnesium oxide.
Classified by particle size: can be divided into magnesium, magnesium oxide and macro -magnesium oxide.
Classification by activity: It can be divided into high -active magnesium oxide, medium -active magnesium oxide and low -active magnesium oxide.
Activated magnesium oxide is a magnesium oxide powder with high surface area and high activity. It has a variety of applications, including:
Rubber industry: Reactive magnesium oxide is used as a reinforcement agent and filler for rubber. It can improve the strength, abrasion resistance and heat resistance of rubber.
Plastic industry: Active magnesium oxide used as plastic fillers and additives. It can improve the strength, stiffness and flame retardability of plastic.
Electronic industry: Activated magnesium oxide is used as insulating materials and flame retardants for electronic components. It can also be used to make ceramic capacitors and piezoelectric ceramics.
Environmental protection: Activated magnesium oxide is used as adsorption agents and flocculants in wastewater treatment. It can also be used to remove sulfur oxides and nitrogen oxides in flue gas.
Active magnesium oxide has a wide range of applications, mainly including:
Catalyst: Magnesium oxide oxide can be used to prepare various catalysts, such as magnesium hydroxide-magnesium oxide catalysts, magnesium oxide-chromium catalysts, etc.
Adsorption agent: Magnesium oxygen can be used to adsorb various gases and liquids, such as carbon dioxide, hydrogen sulfide, and water.
Pinks: Magnesium monpenic oxygen can be used for fillers of rubber, plastic, coatings and other materials to improve the performance of the material.
