Nanomagnesium hydroxide has excellent performance and wide application fields

Nanomagnesium hydroxide is a new type of inorganic material with the chemical formula Mg(OH)2. Nanomagnesium hydroxide appears as white fine powder with a nanosheet layered structure inside. It is easily soluble in ammonium salt solution and strong acid solution, but insoluble in water. Nanoscale magnesium hydroxide has the advantages of good thermal stability, high purity, small particle size, and non-volatility. It is widely used in chemical industry, plastic products, environmental protection, medicine and other fields. Nano-magnesium hydroxide is a subdivided product of magnesium hydroxide, accounting for 50.0% of the market.

The main production methods of nano-magnesium hydroxide include direct precipitation method, spinning disk method, brucite crushing method, chemical liquid precipitation method, metal magnesium hydration method, etc. The direct precipitation method refers to adding sodium hydroxide solution and ammonia monohydrate into the magnesium solution, and producing nano-magnesium hydroxide through forward precipitation or reverse precipitation. This method has achieved industrial production, but by-products are produced during the production process. Calcium salts can easily cause environmental pollution. The brucite crushing method uses natural brucite as the main raw material, and produces nano-magnesium hydroxide through grinding, surface treatment and other processes. Currently, large-scale production has been achieved with this method, but it consumes a lot of energy.

Nanomagnesium hydroxide has a wide range of applications and can be used to produce chemical products such as food additives, flame retardants, flue gas desulfurizers, and food preservatives. In the field of flame retardants, nano-magnesium hydroxide is surface-modified magnesium hydroxide, which has the advantages of smoke suppression, good thermal stability, non-toxicity, and good flame-retardant effect; in the field of food preservatives, nano-magnesium hydroxide It can effectively prevent the biodegradation of muscle fibers such as chicken and pork, and further extend their storage time. With the rapid development of downstream industries, the scale of my country’s nano-magnesium hydroxide market continues to expand. According to the “2022-2027 China Nano-Magnesium Hydroxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , my country’s nano-magnesium hydroxide market size will reach 810 million yuan in 2021, a year-on-year increase of 42.3%.

In the global market, leading nanomagnesium hydroxide companies are mainly concentrated in Japan, South Korea, Europe and the United States, including KYOWA of Japan, Albemarle of the United States, Momentive High-Tech Materials Co., Ltd. of the United States, and Posco Chemical of South Korea. The company Posco et al. In recent years, as the prosperity of my country’s nanomagnesium hydroxide industry continues to increase, its market competition has become increasingly fierce. The main production companies include Anhui Jinhe Industrial Co., Ltd., Western Mining Co., Ltd., etc.

Industry analysts said that nano-magnesium hydroxide has excellent performance and wide range of uses. As market demand is gradually released, the future development trend of the industry will be Keep getting better. As a segmented product of magnesium hydroxide, the market scale of nano-magnesium hydroxide in my country continues to expand. In terms of market competition, the current global nanomagnesium hydroxide market is mainly concentrated in developed countries, and the core competitiveness of domestic enterprises in my country still needs to be improved.
