New building materials are building materials that have developed rapidly in recent years. With its advantages of fire resistance and environmental protection, it has won the favor of experts and scholars in the construction industry at home and abroad. The famous "Bird's Nest" of the 2008 Olympic Games venue has maximized the use of new building materials, combined with high-tech technology to create a world-class cutting-edge construction project.
The raw material of light burnt magnesium powder will become a more hot demand target with the development of the new building materials industry, and the wholesale quantity of light burned magnesium powder will also increase.
Light burnt magnesium powder is used to make refractory materials. The steel industry is the largest consumer of the United States and most of the magnesium-consuming countries. The burnt magnesia produced from magnesite ore, seawater, salt lake or well salt is mainly used in the manufacture of metallurgical furnace refractory products. Light burnt magnesium powder is widely used in various fields. In the water treatment industry, light burnt magnesium powder is used to remove silicon and heavy industry waste liquid in water; it can also be used as a neutralizing agent for industrial waste gas. Light burnt magnesium powder can react with SO2 in flue gas to form magnesium sulfate. Removal of SO2 from industrial waste gas is superior to sulfur removal by calcium compounds. Another use is in the production of magnesium oxychloride and magnesium sulphide cement for the manufacture of industrial and residential building floors.
Among the raw materials of new building materials, the most commonly used is “light burned magnesium powder”. The light burned magnesium powder is made from magnesite, calcined by light burning reverberatory kiln, rotary kiln or boiling furnace. The product is calcined evenly and the quality is stable. High purity and good activity. Can be widely used in paper, chemical, refractory materials, building materials, desulfurization and other industries.
In addition, with the advent of autumn, the weather is gradually getting colder, until the cold winter, the purchase of light burned magnesium powder will probably rise slightly, and the price of light burned magnesium powder will also increase, the specific trend remains to be seen.
Effect of light burnt magnesium ball on liquid phase properties
The clinker liquid amount is too small to be agglomerated, and too much is easy to form a dense large clinker. The amount of liquid phase is related to the content of Al2O3, Fe2O3, K2O, Na2O and MgO contained in the liquid phase. The coefficient of MgO is improved, indicating that MgO has a large influence on the liquid amount and is close to the coefficient of Fe2O3. When the amount of liquid phase is 25% to 28%, it is most advantageous for agglomeration.
Liquid surface tension
The liquid surface tension is an important property of the liquid phase. It has a direct relationship with the granulation. The surface tension of the liquid phase is easy to be agglomerated, and the size of the clinker particles has a good linear relationship with the surface tension of the liquid phase.
The surface tension of the liquid phase is related to the electronegativity of the outer electrons of the element. Some elements such as K, Cl, and S have lower surface tension values, which are not conducive to agglomeration; while the surface tension values of elements such as Mg and Al are higher, which is beneficial to Condensation.
Liquid phase viscosity
The liquidus viscosity values of different components of clinker are different. Generally speaking, the liquidus viscosity value is reduced, which is beneficial to the diffusion of CaO and C2S in the liquid phase to form C3S, and is also easy to be agglomerated. The liquidus viscosity is related to temperature and rises with temperature. And falling
