Study on the mechanical properties of magnesium hydroxide filled EVA copolymer

Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is the most popular inorganic flame retardant on the market. However, due to the “hydrophilic and oleophobic” properties of the surface of magnesium hydroxide, there will be poor compatibility with resin in practical applications. The situation, coupled with its own low flame retardant efficiency, directly hinders the further use of magnesium hydroxide in the actual production process. Surface treatment of magnesium hydroxide can not only improve the compatibility between magnesium hydroxide and resin, but also improve the flame retardancy. Filling EVA with magnesium hydroxide (Mg(OH)2) can improve the thermal stability…

Research on the process of preparing silicon steel grade magnesium oxide from magnesium hydroxide

Hebei Messi Biology Co., Ltd. stated that silicon steel, as an important electromagnetic material, is widely used in motors, transformers, generators and other fields, and plays an important role in improving motor efficiency, reducing losses, and extending service life. Magnesium oxide is a common additive in silicon steel, which can increase the magnetic permeability and magnetic saturation induction intensity of silicon steel, thereby improving its electromagnetic properties. Therefore, preparing high-purity and high-quality magnesium oxide is one of the key issues in the production process of silicon steel. At present, the methods for preparing magnesium oxide mainly include chemical methods,…

Application of magnesium oxide in new memories

Hebei Messi Biology Co., Ltd. stated that the crystallinity, texture calibration and original interface quality of the film in the new memory ultimately determine the performance of the MRAM device, among which the formation of tunnel junction magnesium oxide is the most critical. Considering that the deposited reference layer and magnesium oxide barrier layer are mostly amorphous in nature, they are first annealed to crystallize them, and then part of the stack is cryogenically cooled to create a cryogenic surface to promote sharp atomic interfaces in the free layer. . After the complete stack is deposited, another anneal is…
