magnesium oxide

Hebei Messi Biology Co., Ltd. stated that magnesium oxide is mainly used in brominated butyl rubber plugs and halogenated butyl rubber plugs, and its main functions are vulcanization accelerator and acid absorption. Requirements for magnesium oxide: Generally, both light and active magnesium oxide are used. Light magnesium oxide requires MgO ≥ 93-95%, CaO ≤ 1.5%, […]

Direct calcination method Hebei Messi Biology Co., Ltd. stated that this method is to directly calcine magnesium salt or magnesite at high temperature to obtain magnesium oxide. Magnesium carbonate pentahydrate (4MgCO3·Mg(OH)2·5H2O) and magnesium hydroxide were calcined at 450°C for 3h to obtain magnesium oxide products with average sizes of 9nm and 4.8nm, respectively. The direct

It integrates scientific research, development, production, and sales of magnesium salt series products such as magnesium oxide, magnesium carbonate, magnesium sulfate, and magnesium hydroxide. It is mainly engaged in the production and operation of magnesium

Hebei Messi Biology Co., Ltd. stated that silicon steel grade magnesium oxide is a magnesium oxide coating material used to manufacture oriented silicon steel sheets and is a high value-added magnesium oxide product. At present, the United States and Japan are at the forefront of the research and preparation of silicon steel grade magnesium oxide.

Hebei Messi Biology Co., Ltd. stated that silicon steel grade magnesium oxide is a relatively economical magnesium oxide coating material, and it is also a high value-added magnesium oxide product. China is a major producer of magnesium compounds, ranking first in the world, but the product grade is low, the production scale is generally small,

Hebei Messi Biology Co., Ltd. stated that the raw materials for preparing silicon steel grade magnesium oxide are mainly magnesite (MgCO3), dolomite (CaCO3·MgCO3), magnesium-containing industrial byproducts, seawater or salt lake brine (MgCL2), etc. The production process can be divided into magnesium ore carbonization method and ammonium carbonate method with basic magnesium carbonate as intermediate, and

Hebei Messi Biology Co., Ltd. stated that with the rapid development of my country’s electromechanical industrialization, the entire market demand for silicon steel in special steel has put forward new requirements in terms of quality and quantity, and there is also a huge gap. Therefore, domestic silicon steel sheet production is in a period of

Hebei Messi Biology Co., Ltd. stated that with the development of the Congo (DRC) project, the hydrometallurgy of copper-cobalt mines has been vigorously developed in recent years. Compared with the traditional processes currently used, the technical advantages of many process flows applied to hydrometallurgy are unique. Many processes for purifying cobalt through precipitation operations have

Hebei Messi Biology Co., Ltd. stated that based on the first domestic silicon steel continuous annealing-coating experimental unit project developed by a steel plant, it conducted research and analysis on the selection of magnesium oxide for oriented silicon steel coating, developed a magnesium oxide coating system for oriented silicon steel, and studied the magnesium oxide

Hebei Messi Biology Co., Ltd. stated that magnesite is a magnesium carbonate with a chemical formula of magnesium carbonate (MgCO3), theoretical components: MgO: 47.81%, CO2: 52.19%, density of 2.9-3.1g/cm3, hardness of 3-5. Magnesite can be divided into crystalline and amorphous types according to its crystal state. Crystalline magnesite is rhombic hexahedron, columnar, plate-like, granular, dense,
