Magnesium oxide: The world is "magnesium" beautiful because of you
Introduction
In the field of industrial production, there is a white powder that is tasteless, odorless, non-toxic, and seemingly ordinary, but it plays a pivotal role in the industrial field. This alkaline earth metal oxide is magnesium oxide (MgO), which is known as the "industrial MSG".
Magnesium oxide is a typical ionic compound. Because of its excellent chemical stability, high melting point and excellent thermal stability, it is widely used in many industrial fields, and its uses cover almost every aspect of our lives.
Multiple applications of magnesium oxide
1. Abrasives and fillers
Magnesium oxide is often used as fillers and abrasives for products such as plastics, paints, and coatings. Its role not only improves the wear resistance, hardness and stability of the material, but also extends the service life of the product, bringing a qualitative improvement to industrial products.
2. Chemical raw materials
As an important chemical raw material, magnesium oxide is widely used in the production of magnesium bricks, magnesium fertilizers, magnesium salts and other products. At the same time, it can also be used as an adsorbent, catalyst or carrier in chemical production such as synthetic ammonia, natural gas processing and petroleum refining.
3. Microwave absorbing materials
Ultrafine magnesium oxide has high dispersibility and high activity, and can be compounded with a variety of polymer materials to prepare microwave absorbing materials with excellent performance. This composite material not only has outstanding microwave absorbing effect, but also can maintain the strength and toughness of the raw materials. If fibrous magnesium oxide is added, it can play an excellent reinforcing role.
4. Rubber products
In the rubber industry, magnesium oxide performs well as a fire retardant. It can inhibit the combustion and propagation of flames by reducing the oxygen concentration, while also preventing rubber aging and reducing smoke generation.
Therefore, magnesium oxide is widely used in rubber products such as belts, tires, cables, sealing materials and fireproof pipes, giving them higher safety and durability.
5. Refractory materials
Magnesium oxide is an important raw material for the manufacture of refractory materials. Its characteristics are to improve the thermal shock resistance, erosion resistance and refractoriness of the material. Therefore, it occupies an indispensable position in the production of refractory materials in high-temperature environments such as ceramics, blast furnaces and electric furnaces.
6. Metallurgical materials
In the metallurgical industry, magnesium oxide is used as a dephosphorization and desulfurization agent to improve the purity and quality of steel products and optimize the smelting process.
7. Advanced lubricant additives
Magnesium oxide plays multiple roles in advanced lubricants as a desulfurizer, detergent and vanadium inhibitor. It not only improves the rheology and sealing properties of the lubricating film, but also effectively reduces the pollution of fuel waste to the environment, especially in the process of oil refining and heavy oil combustion, it can greatly reduce the damage to equipment and improve the quality of fuel.
8. High-performance ceramics
Magnesium oxide can be used to manufacture multifunctional magnesium oxide films or high-density fine-grained ceramics due to its excellent sintering properties. These materials are particularly outstanding in highly corrosive and high-temperature environments and are one of the important directions of cutting-edge ceramic technology in the future.
9. Building materials
In the construction industry, magnesium oxide is used to prepare products such as sound insulation boards, lightweight thermal insulation materials and fireproof boards. These materials have multiple functions of sound insulation, fire prevention and thermal insulation, providing more comfortable and safe protection for modern buildings.
