As a chemical raw material, magnesium oxide has a wide range of uses and occupies a very important position in the national economy. It is widely used in plastics, rubber, coatings, patent leather, rayon, refractory materials and other industries. Therefore, the preparation of magnesium oxide plates or raw materials often has difficulties in dispersion. After all, most of the magnesium oxide is ground with nano-fineness. At this time, the dispersion problem requires sufficient knowledge and technology, which also plays the role of magnesium oxide dispersant.
For example, magnesium oxide is ground and dispersed into a common ceramic slurry. During the ball milling process of preparing the slurry, the slurry will solidify, has no fluidity, cannot be sprayed, and the water content will increase. This is because magnesium oxide (MgO) molecules in the partially dissolved slurry solution form OH-O-MgO-Mg-OH chains in the water medium.
In order to overcome this phenomenon, the product formed by the interaction with the magnesium oxide forms a coating layer around the surface of the magnesium oxide, restricts the formation and interaction of the chain, stabilizes the slurry, maintains fluidity, and can be spray-dried smoothly to obtain a good Particles. At the same time, after the magnesium oxide ceramic slurry is dried, the coating layer prevents the magnesium oxide powder from re-aggregating, and after it is uniformly dispersed on the ceramic coating, the high-purity magnesium oxide can be used in medicine and coatings. Additives in food and feed, catalyst carriers, ceramic glazes, additives for ceramic production, and thermal insulation materials. In addition to the friction material magnesium oxide used in industry and silicon-grade magnesium oxide used in the iron and steel industry, magnesium oxide also has important applications in the defense, military, and aerospace fields. Applied to so many industrial fields, the market is ideal, so in the solution that needs to solve the magnesium oxide, there is also a certain technical threshold in the necessary auxiliary products.
