This testing covers all aspects of the device, including but not limited to…

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…

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,…

From November 15th to 17th, the 2023 China International Coatings Exhibition opened grandly at the Shanghai New International Expo Center. Manager Zhang from the Sales Department of Hebei Messi Biology Co., Ltd. attended the exhibition. The China International Coatings Exhibition has been serving the industry since 1996 and is currently held alternately in Shanghai and Guangzhou every year. It has been committed to providing an international display and trade platform for suppliers and manufacturers in the coatings industry to face-to-face contact with the world, especially those from China and Asia. audience. Manager Zhang said that the magnesium oxide and…

Among magnesium products, flame-retardant magnesium hydroxide is uniquely attractive due to its huge domestic and international market potential. With the rapid development of the plastics industry, the demand for flame-retardant thermoplastic polymers is increasing day by day. The demand for flame retardants, especially the demand for magnesium hydroxide flame retardants that are non-toxic, smoke-suppressing and have high thermal stability will be even greater. For urgency. Magnesium hydroxide flame retardant can be used in various composite materials such as wires, cables, home appliances, and building materials. It is especially suitable for use with polymers such as PP, PA, and POM…

Hebei Messi Biology Co., Ltd. stated that magnesium oxide has good chemical inertness, heat resistance, insulation and thermal conductivity. Among them, the most outstanding ones are good high-temperature oxidation resistance, moderate alkalinity, the presence of oxygen vacancies and single electrons. The resulting electrophilicity and so on. Among magnesium oxide particles with different shapes, spherical particles have regular morphology, uniformity, large specific surface area and good sphericity, which can greatly improve the adsorption, thermal conductivity and catalytic performance of the product. Therefore, spherical magnesium oxide has many aspects They all have very effective applications, mainly in the following aspects: 1….

Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide, as an additive inorganic flame retardant, has good thermal stability, is non-toxic, suppresses smoke, and effectively promotes carbonization of substrates. It does not produce corrosive gases while also It has the function of neutralizing acidic and corrosive gases generated during combustion and is an environmentally friendly green flame retardant. However, magnesium hydroxide has poor dispersion and compatibility in polymer materials, which often leads to a decrease in the mechanical properties of flame retardant materials. In order to address these problems, this article uses the following methods to prepare and modify…

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…

Hebei Messi Biology Co., Ltd. stated that electric heating tubes use fused crystalline magnesium oxide, which has better properties than caustic magnesium. Magnesite is arc melted at 2800°C to obtain large crystalline magnesium oxide, which is crushed and After grinding, sieving and magnetic separation, fused crystallized magnesium oxide powder is obtained, and its purity can reach more than 96%. The well-crystallized magnesium oxide does not react with water or carbonic acid gas. In tubular electric heating elements with temperatures above 400°C, crystallized magnesium oxide is a better filler. What is the function of magnesium oxide powder: 1. Thermal conductivity…
