How is the magnesium hydroxide

The brucite manufacturer will answer for you. Polymer materials are widely used in daily life, but because of their flammability, smoke emission and other characteristics, it is easy to become the direct activator of fire, because it is necessary to carry out flame retardant treatment on polymer materials, and the most direct way is to add flame retardant. Among many flame retardants, magnesium hydroxide is undoubtedly an excellent one. When it is heated, it will release bound water to absorb a lot of latent heat and reduce the surface temperature of the filled synthetic material in flame. What's more, magnesium hydroxide can also suppress smoke-in fire, more than 80% of the victims are not burned to death, but suffocated by thick smoke. Once magnesium hydroxide flame retardant is added, the smoke density during burning can be greatly reduced, and the risk of people choking to death can be reduced. Since the flame retardant effect of magnesium hydroxide is so good, the natural demand will be relatively large, such as rubber, chemical industry, building materials, plastics and electronics, unsaturated polyester, paint, coatings and other fields are all major consumers of magnesium hydroxide. China is rich in magnesium resources and has unique resource advantages. At present, brucite is the main raw material for extracting magnesium hydroxide, and most of them are concentrated in Dandong area in Northeast China. Geographical superiority has prompted several local related enterprises to emerge, for example, Dandong Tianci Flame Retardant Materials Technology Co., Ltd. is one of the best. According to Wu, general manager of Dandong Tianci, because the raw material brucite is easy to obtain, physical crushing is often used in local processing. Generally, the ore is directly crushed, and magnesium hydroxide products with the required particle size grade are produced after dry coarse grinding and wet ultrafine grinding. Because this process is relatively simple, it is easy to cause uneven particle size distribution of magnesium hydroxide products. However, it is amazing that the gifted magnesium hydroxide products can perfectly avoid this point. When asked about the reasons, General Manager Wu explained that they would not only adopt advanced Japanese production technology and imported equipment from Japan and Germany, but also make corresponding improvements to the equipment in view of many defects in the traditional process, and developed a unique technical formula with strict management system and perfect testing instruments, which not only broke through the uniqueness of magnesium hydroxide by chemical method and ore method, but also had the advantages of high purity and high cost performance. At the same time, the whole production process has almost zero emissions, which meets the development requirements of environmental protection. In recent years, due to environmental protection policies, changes in people's consumption concepts and other reasons, the demand of magnesium hydroxide in the fields of heat conducting plastics, insulating materials, wires and cables, coatings and so on has been increasing.
