The main difference between magnesium olive sand and aluminum alloy is that magnesium olive sand is an active metal, which can produce a chemical reaction in the air.

Magnesium olive sand is a kind of material that is used more now. Magnesium olive sand needs surface treatment when it is processed again. So what is the surface treatment of calcined magnesium olive sand? Here is a small editor to share this knowledge with you.

The main difference between magnesium olive sand and aluminum alloy is that magnesium olive sand is an active metal, which can produce chemical reactions in the air, and requires corresponding requirements for the processing process, environment, water and chemical raw material processes, or the direct result is that the surface will be corroded or oxidized, which is not conducive to surface treatment.

The surface treatment effects that magnesium olive sand can now do include: magnesium olive sand anodizing, magnesium olive sand micro-arc oxidation, magnesium olive sand electroplating, magnesium olive sand oil spraying, magnesium olive sand spraying, magnesium olive sand passivation, magnesium olive sand skin film and other processes. In previous years, due to the high cost of surface treatment, the amount of magnesium olive sand has not been able to be used in large quantities.

Now, with the strong support of new energy and new materials from the state, the surface treatment of magnesium olive sand has also been vigorously developed. The processes such as micro-arc oxidation of magnesium olive sand, electroplating of calcined magnesium olive sand, oil spraying of magnesium olive sand, spraying of magnesium olive sand, passivation of magnesium sand, and coating of magnesium olive sand have gradually matured and the treatment cost has been continuously reduced, new energy vehicles, high-speed rail, aircraft, aerospace, satellites, 3C products, building decoration materials, batteries, etc. are all expanding the use of magnesium olive sand.

Moreover, magnesium olive sand is easy to corrode. To put it simply, it is mainly divided into general corrosion and electrochemical corrosion. The purpose of surface treatment is to reduce or avoid corrosion. Surface treatment generally requires cleaning, degreasing, pickling, coating, coating and other treatments. What we usually call the surface treatment of magnesium olive sand parts refers to the coating process.

How to choose high-quality calcined magnesite sand

How to Choose High-Quality Calcined Magnesite Olivine Sand In industries such as metallurgy and casting, calcined magnesite olivine sand is an important refractory material, and its quality directly affects production efficiency and product quality. So, how can one select high-quality calcined magnesite olivine sand? Purity is the primary consideration. High-purity calcined magnesite olivine sand has fewer impurities and better refractory performance. In high-temperature environments, impurities may trigger chemical reactions, reducing the material's stability and service life. One can check the product's inspection report to clarify the content ratio of major components such as magnesium oxide (MgO) and silicon dioxide (SiO₂). Generally, a magnesium oxide content of 40% - 50% and a silicon dioxide content of around 35% - 45%, with low levels of other impurities, are ideal. Particle size distribution should not be overlooked. Different application scenarios have different requirements for particle size. For example, in precision casting, products with uniform particle size and a higher proportion of fine particles are needed, as this can make the mold surface smoother and reduce casting defects. In some applications requiring high strength, such as large metallurgical furnace linings, an appropriate ratio of coarse particles can enhance the structural strength of the material. Therefore, it is essential to choose magnesite olivine sand with a particle size distribution that matches actual usage needs. Additionally, the degree of calcination is crucial. Fully calcined magnesite olivine sand has a stable crystal structure, offering better volume stability and slag erosion resistance. One can initially judge by observing the product's appearance and color; products with uniform color and dense texture are usually well-calcined. It is also advisable to consult suppliers to understand their calcination processes and temperature control. When selecting calcined magnesite olivine sand, a comprehensive assessment of purity, particle size distribution, and calcination degree, combined with one's actual production needs, is necessary to choose a suitable product that aids in efficient and stable production, enhancing product quality and economic benefits for the enterprise.
