Slurry magnesium hydroxide raw materials from seawater, with abundant raw materials, good fluidity, high activity, non-coagulation, non-corrosive, strong adsorption capacity, safe and non-toxic, etc., the application of a wide range of scenarios. Slurry magnesium hydroxide refers to the emulsion containing 30%-60% magnesium hydroxide, the appearance of white or light brown, placed in 1 month without obvious delamination.
Magnesium hydroxide is a kind of inorganic material, and the production process includes chemical synthesis method, magnesium oxide hydration method, magnesite grinding method and so on. With good adsorption capacity, buffer and environmental performance, magnesium hydroxide is widely used in environmental protection, electronics, medicine, paper, oil additives, aquaculture, insulation materials and other fields, 2023 China’s magnesium hydroxide market size of more than 800 million yuan. Slurry magnesium hydroxide as one of the main types of industrial production of magnesium hydroxide, the application is also more and more extensive.
In the field of environmental protection, slurry magnesium hydroxide can be used as desulfurization agent, neutralizer, applied in drinking water purification and arsenic removal, acidic wastewater treatment, heavy metal wastewater treatment, flue gas desulfurization, toxic gases adsorption and other scenarios; in the field of papermaking, the slurry magnesium hydroxide can be used as a substitute for caustic soda, used in the bleaching operation of the pulp.
According to the different calcium oxide mass fraction, slurry magnesium hydroxide is divided into Class I (≤0.4%), Class II (≤0.8%), of which Class I slurry magnesium hydroxide is mainly used in sulfuric acid wastewater neutralization and other areas with special requirements for calcium oxide content.
According to the “2024-2029 China Magnesium Hydroxide in Slurry Industry Market Depth Research and Development Prospect Forecast Report” released by Xinsiye Industry Research Center, industrial wastewater treatment is the main application scenario of magnesium hydroxide in slurry. In recent years, the state attaches higher importance to ecological environment management, China’s industrial wastewater treatment capacity has been growing year by year, and the daily treatment capacity in 2023 reached more than 180 million tons. With the release of sewage resource demand, policy guidance continues to be clear, industrial wastewater treatment industry long-term incremental space is vast. Overall, the industrial wastewater treatment field of slurry magnesium hydroxide demand for long-term and stable.
The United States, Japan and other regions of the slurry magnesium hydroxide market development is faster, of which the United States slurry magnesium hydroxide annual consumption of more than 200,000 tons. China’s slurry magnesium hydroxide production enterprises have Hebei magnesium Xi Biological Co., Ltd, Qinghai West Magnesium Co., Ltd. is the largest domestic chemical method of magnesium hydroxide production enterprises, with an annual production capacity of 150,000 tons.
Messi Biology industry analysts said, slurry magnesium hydroxide is one of the main forms of production and application of magnesium hydroxide, with good fluidity, easy to transport/storage, non-coagulation and other characteristics, the application of a wide range of scenarios. Slurry magnesium hydroxide is mainly used in industrial wastewater treatment as the representative of the environmental protection field, in recent years, as the country’s emphasis on ecological environmental management to enhance, slurry magnesium hydroxide application space is expanding.
