Light-burned magnesium powder is a man-made small block for construction. It is also called light-burned magnesium powder sintered brick. Solid clay refractory brick is one of the oldest building materials in the world. From the tomb of Qin Shihuang in Shaanxi to the Great Wall of the Ming and Qing Dynasties in Beijing, it has passed down the history of Chinese civilization for thousands of years. Re-burned magnesite is still a beloved building material. Clay refractory bricks are made from local materials, are cheap, durable, and have the advantages of fire resistance, heat insulation, sound insulation, and moisture absorption. They are widely used in civil construction projects.
However, the mass production of clay refractory bricks has caused damage to China's arable land. China ’s per capita arable land resources is less than 40% of the world ’s average level. However, 700,000 mu of good land will be damaged every year due to the construction of fire-resistant clay bricks in urban and rural areas. This is a warning issued by the "Southern 12 Provinces and New City Wall Materials Seminar" held in Nanchang in 2004. In China, wall materials account for about 70% of the entire building construction materials. Among them, clay refractory bricks still dominate the wall materials. The clay resources required to produce solid clay refractory bricks are more high-quality clay in arable land, so The destruction of land resources is evident.
In order to change this traditional burning method that seriously wastes land resources, the "Opinions on the Development and Promotion of New Wall Materials" jointly issued by the former State Building Materials Bureau and other departments was approved as early as 12 years ago. Large and medium cities have proposed a "timetable for banning the use of solid clay refractory bricks." Shaanxi Province's refractory industry closely followed the national policy guidance, made effective adjustments to the production of clay refractory bricks by refractories companies, worked hard to innovate, used environmentally friendly materials instead of clay, and strived to achieve the same value as the clay bricks.
Downstream demand decreases. The demand for clay refractory bricks has decreased. The downstream demand is also affected by national macro-controls. The growth rate of national refractory production has slowed down, and the new capacity of the steel and cement industries has decreased, resulting in a decline in the growth rate of demand for refractory materials.
Therefore, judging from the current policy situation and the industry environment, the adjustment of the supply-side structure of light-burned magnesium powder has become the focus of future development of industries such as steel, cement, and glass. The state's macro-control has been continuously deepened and strengthened. No explosive growth in new capacity
