SMC material is composed of SMC special yarn, unsaturated resin, low shrinkage additives, thickeners and other fillers. It has a wide range of applications in the transportation vehicle, construction, and electronic/electrical industries because of its superior electrical properties, corrosion resistance, and high flexibility. During the preparation of SMC, thickening agents have a great influence on […]

Magnesium oxide to play excellent performance in different materials and applications, can not be separated from the basic research and industrial research and development in conjunction. Hebei Messi Biology Co., Ltd. pointed out that the current magnesium oxide industry is still in the low-end field, which is in urgent need of transformation and upgrading to

Light magnesium oxide reacts with water to generate magnesium hydroxide, powdered magnesium oxide reacts with sewage to generate magnesium hydroxide MgO+H2O=Mg(OH)2, magnesium hydroxide has the characteristics of buffering, large activity, strong adsorption capacity, not corrosive, safe, non-toxic and harmless, which can react out the harmful impurities such as silica in sewage, and has been widely

The heat resistance of rubber is closely related to its molecular structure and rubber components, temperature, mechanical action and surrounding environmental media. Usually the chemical stability of rubber is also a key factor affecting the heat resistance performance. General conventional light-colored filler heat resistance aging performance is better than reinforcing filler carbon black, can choose

ICP, XRD, particle size distribution characterization and volumetric resistivity of magnesium oxide powder were carried out by Hebei Messi Biology Co., Ltd. The results show that the insulation performance of magnesium oxide powder is not related to magnesium oxide crystalline structure, but to the particle size distribution of magnesium oxide. The narrower the particle size

Pharmaceutical food grade magnesium oxide is a fine magnesium salt products, only a small amount of domestic production, only a few enterprises such as Hebei Messi Biology Co., Ltd. economic benefits; most of the small size of enterprises, quality is not high, backward technology and equipment, poor market development capabilities, the industry itself is not

Components such as filters, resonators and oscillators composed of microwave dielectric ceramics are widely used in 5G networks, and their quality largely determines the final performance, size limit and cost of microwave communication products. One of the most important raw materials in microwave dielectric ceramics is magnesium oxide. High purity magnesium oxide has a large

Lithium-ion batteries are able to be recharged twice during use and are a kind of secondary rechargeable battery. The main working principle is the repeated movement of lithium ions between positive and negative electrodes, and the main components are electrolyte, positive electrode sheet, negative electrode sheet and diaphragm regardless of the shape of the battery.

Foam ceramics have good three-dimensional three-dimensional mesh skeleton structure, in the production of magnesium oxide additives need to be used.   Magnesium oxide has good adsorption and filtering effect on impurities in foam ceramics, which can filter various inclusions and impurities in magnesium and magnesium alloy melt, improve the intrinsic quality of castings and reduce
