The method of magnesium aeroge.
Background technique
China salt lake is numerous, and magnesium resource abundant is contained in salt lake bittern.By taking Qinghai Chaerhan salt lakes as an example, wherein chlorine
16.5 hundred million tons of magnesium reserves of change, the 74% of Zhan Quanguo magnesium salts resource, bischofite (magnesium chloride hexahydrate, MgCl2•6H2It O is) in the world
(content up to 96%) best in quality, the maximum magnesium raw material of yield.The development of potash fertilizer industry is that the production of National Agricultural plays promotion
Effect, but since one ton of potassium chloride of every extraction just has 8 ~ 11 tons of magnesium chloride to flow back to salt lake, result in the part of magnesium salts in salt lake
Enrichment becomes " magnesium evil " in the development process of salt lake, this not only causes the serious waste of magnesium resource, but also breaks to a certain extent
It is broken the structure of salt lake resources, influences the sustainable exploitation utilization of salt lake resources.By means of the superior evaporation conditions in the Caidamu Basin
Make Saturated with Magnesium chloride bittern continue to evaporate, can get magnesium salts primary product bischofite, Cha Er Han Salt Lake can produce tens of every year
Ten thousand tons of bischofites, but price is cheap, and about 200 yuan/ton ~ 300 yuan/ton, added value is very low.Therefore, it is with salt lake magnesium resource
The important channel that raw material directly prepares high-performance, the functional material of high added value is the development and utilization of salt lake magnesium resource.
Aeroge is a kind of nano material with three-dimensional continuous poriferous network structure, have high porosity, low-density and
The performance characteristics such as the structure feature and thermal conductivity of high-specific surface area are low, the low harmony propagation rate of refractive index is low.Because its is excellent
Heat-proof quality (even lower than thermal conductivity (0.024 Wm of air-1·K-1)), aeroge is known as ultra heat insulating material again,
Change the green material in the world.Aeroge can be widely applied to aerospace, building, stone because of its excellent physicochemical properties
The fields such as oil, liquefied gas, military affairs, chemical industry, Thermal Power Engineering, Thermal Equipment, communications and transportation, household electrical appliance, naval vessel.Wherein, it gathers around
Having the porous magnesia aerogel material of nanostructure has high-specific surface area, will be the features such as high catalytic activity, lower thermal conductivity
The multiple fields such as catalysis, gas absorption, high efficiency heat insulation material have a wide range of applications.
