The production of light-burned magnesium powder will become an important development direction

Light burnt magnesia powder is an artificial small block material for construction. Also known as light burnt magnesia powder sintered brick. Solid clay refractory bricks are one of the oldest building materials in the world. From the Mausoleum of Qin Shihuang in Shaanxi to the Great Wall of Ming and Qing Dynasties in Beijing, it has inherited the history of construction civilization of the Chinese nation for thousands of years. So far, it is still a favorite architectural material of the people. Clay refractory bricks adapt to local conditions, are cheap, durable, and have the advantages of fire prevention, heat insulation, sound insulation, moisture absorption, etc., and are widely used in civil construction projects.

 However, the large-scale production of clay refractory bricks has caused damage to the cultivated land area in my country. my country's per capita arable land resources are less than 40% of the international average level, but due to the construction of urban and rural houses to burn clay refractory bricks, 700,000 mu of fertile land will be destroyed a year. This is the warning announced at the "Seminar on New Wall Materials for 12 Provinces and Cities in the South" held in Nanchang in 2004. In my country, the wall materials account for about 70% of the building materials of the whole house, among which the clay refractory bricks still dominate the wall materials. , its damage to land resources is evident.

 my country has a variety of raw material routes to produce magnesium oxide enterprises, especially in the past ten years, the dolomite carbonization method has developed by leaps and bounds, and has formed its own characteristics in terms of technology and equipment. Calcium carbonate was successfully prepared and used, which largely solved the pollution problem caused by dolomite carbonization. Moreover, in recent years, traditional brine-based magnesium salts are developing into high-purity, high-value-added, functionalized and functionalized products.

 Light Burnt Magnesium Powder Production

 To sum up, we know that magnesium oxide is not harmful to the body, so everyone can use it with confidence.

 1. In the stock magnesia, take out 100 grams of magnesia samples from different corners and different positions (not less than 3 places), and mix them evenly.

 2. Accurately weigh 100g of magnesium oxide powder from the mixed powder, put it in a constant-weight dry beaker, add 400g of pure water to make it completely wet.

 3. Put the cup into a drying oven with adjusted temperature (110℃), bake for more than 2 hours, and then adjust the oven to 150℃ to dry the sample to constant weight. Activity calculation method: active content of magnesium oxide = [(W-100)/45] X 100% where 100 is the weight of the sample before hydration; W is the weight of the sample after hydration; 45 is the conversion factor. Note: In order to obtain a more accurate value, you can take three 100g magnesium oxide assays, add the obtained active content values, and divide by 3,

 Problems that need attention: ①During the heating process, avoid the slurry splashing out of the beaker; ②The drying time is as long as possible to ensure that the water is completely evaporated.
