Application of laser particle size analyzer in magnesium oxide

The particle size of magnesium oxide has a significant impact on its application, which is specifically reflected in the following aspects:

1. In the field of refractory materials Density and strength: Magnesium oxide powder with smaller particle size can be packed together more closely when made into refractory materials (such as magnesia bricks, etc.). Because the gaps between small-sized magnesium oxide particles are relatively smaller, the structure of the formed refractory material is denser, thereby improving the strength and corrosion resistance of the refractory material. For example, in magnesia-carbon bricks used in steel-making furnaces, the use of fine-grained magnesium oxide can enhance the service life of the bricks in high-temperature and highly corrosive environments.

2. In the field of rubber industry Reinforcing effect: Magnesium oxide is used as a reinforcing agent for rubber, and its reinforcing effects vary with different particle sizes. Fine-grained magnesium oxide can be better dispersed in the rubber matrix and have more contact points with the rubber molecular chain, thereby more effectively improving the tensile strength, wear resistance and other mechanical properties of the rubber. For example, in the tire rubber formula, adding an appropriate amount of fine-grained magnesium oxide can improve the wear resistance and load-bearing capacity of the tire.

3. In the field of chemical industry

Adsorption performance: Magnesium oxide has a certain adsorption capacity, and its particle size has an impact on the adsorption performance. Fine-grained magnesium oxide has a larger specific surface area and more adsorption sites. Therefore, when adsorbing gases (such as carbon dioxide, sulfur dioxide, etc.) or impurities in the solution, it can adsorb more substances and improve the adsorption efficiency. This has important applications in waste gas treatment, wastewater purification, etc., such as adsorbing carbon dioxide in industrial waste gas to reduce carbon emissions, or adsorbing heavy metal ions in wastewater treatment.

4. In the field of electronic industry

Coating quality: Magnesium oxide is often used as a surface coating on electronic components to protect and dissipate heat. Magnesium oxide with smaller particle size can be more evenly dispersed in the coating solution when preparing the coating, forming a more uniform and smooth coating, improving the quality and protective effect of the coating, and ensuring the normal operation of electronic components in complex environments. .

5. In the field of medicine

Drug release rate: In some pharmaceutical preparations, magnesium oxide can be used as an excipient or antacid. Particle size will affect the release rate of the drug. Fine-grained magnesium oxide may increase the contact area between the drug and the liquid in the gastrointestinal tract, thereby speeding up the release rate of the drug and exerting its effect faster. For example, in medicines used to treat hyperacidity, magnesium oxide of appropriate particle size can help neutralize gastric acid in time and relieve gastric discomfort.
