Analysis of current and future demand for reactive magnesium oxide in China
The application of reactive magnesium oxide is very wide, and it can be divided into many different types according to the different uses. Activated magnesium oxide is mainly classified according to the iodine absorption value, divided into high activity 120~180, medium activity 80~120, low activity 40~80.
Reactive magnesium oxide is widely used in light-emitting devices, gas sensors, various rubber products, glass steel, fluorine rubber, catalysts, adsorbents, etc., showing its excellent performance. In recent years, through continuous development and application research and development, active magnesium oxide has been widely used in rubber products, glass steel, petrochemical and other fields.
There are many magnesium oxide production enterprises in China, especially in the last ten years, the dolomite carbonization has developed rapidly, with Chinese characteristics in technology and equipment. Scientific and technological achievements have been emerging and applied to production practice. Successfully prepared calcium carbonate containing magnesium and used to manage the pollution of dolomite carbonization waste residue, protect the environment and improve the economic efficiency. In the international leading level:The successful use of magnesite carbonation method has greatly reduced the production cost of magnesium chemical materials; the traditional method of making magnesium chemical raw materials from brine is developing to high purity, high value-added, specialized and functionalized commodities.
At present, the domestic market is booming, leading to an increasing demand for reactive magnesium oxide. The major magnesium salt manufacturers, led by Hebei Messi Biology Co., Ltd, have invested a lot of manpower and material resources in the research and development of reactive magnesium oxide, and have achieved good results. However, looking at the domestic
reactive magnesium oxide market, many small enterprises are still using the traditional equipment and process to produce active magnesium oxide, resulting in unstable product quality and small annual production capacity, which can not meet the demand of the reactive magnesium oxide market at all.
Magnesium oxide is mainly used as accelerator and activator for butyl rubber, neoprene, spherical butadiene rubber and fluorine rubber.In 2020, the market size of such applications will exceed 1.5 billion yuan, reaching 1.53 billion yuan, an increase of about 3.7% year-on-year. In terms of the regional share of consumption in 2020, East China takes the first place, accounting for 22.6% of the total consumption, North China market accounts for about 19.0%, South China market accounts for 17.5%, Central China 15.3% and Southwest China 13.1%.
Domestic production of high-end special magnesium oxide enterprises are few. It is understood that at present, only Hebei magnesium Xie biological limited company capacity broken 10,000 tons of capacity. It is believed that in the future, magnesium oxide to truly out of China, to the world, it is necessary to fill the gap of special magnesium oxide in the industry, subdivision of magnesium oxide industry product categories, so that the magnesium oxide industry really towards high precision and refinement.
