Ultrafine refinement of magnesium hydroxide powder becomes a hot spot
Jul 23, 2018

The ultrafine refinement of magnesium hydroxide powder has become a hot issue. The smaller the particle size of the magnesium hydroxide flame retardant, the better the flame retardant effect. As the particle size of the magnesium hydroxide powder decreases, its specific surface area increases, and the surface properties change, which helps to improve the mechanical properties of the product. Therefore, compared with other paths, the ultra-fine granularity is more conducive to improving the market competitiveness of enterprises. Powder particle size refinement is simpler than other processing paths, and high-grade powders can be produced at low cost, and the products are more versatile. Therefore, it is necessary to strengthen the production equipment and innovative technology of ultrafine powder, and the improvement of processing equipment and technology is crucial to the grade of the advanced magnesium flame retardant.

Strengthen the surface activation modification technology equipment of magnesium hydroxide. The selection of excellent surface modifiers, suitable activation technology, etc., requires efficient surface activation treatment equipment to match, which is a necessary condition for surface activation modification of magnesium hydroxide. To this end, research and development such as continuous activation equipment that promotes activation and production capacity should be strengthened. At the same time, the wet processing technology is studied, the consumption of the processing is reduced, and the cost of the activation treatment is reduced.

Aiming at the development of plastic halogen-free flame retardants and the new direction of flame retardant technology, low-smoke, high-efficiency, halogen-free and multi-functional new flame retardants are also the main development direction. The prospects for inorganic flame retardant materials suitable for flame retardant functions in cables, automotive cables, electrical appliances, composite materials, etc. are very broad. Low-smoke, high-efficiency, halogen-free and composite new flame retardants are very popular in the industry. Great application prospects.
