Description
Technical field
The present invention relates to a kind of preparation methods of devitrified glass, and in particular to a kind of to utilize aluminium ash for main material production rosy clouds
The method of stone devitrified glass.
Background technology
Cinder microcrystalline glass is introduced a certain amount of using the industrial residues such as metallurgical slag, tailing and natural minerals as primary raw material
The auxiliary materials such as Nucleating Agent, fluxing agent, through a kind of micro crystal material made of the processes such as dispensing, fusing, molding, annealing, crystallization.
With the quickening of China's process of industrialization, various slags, tailing are largely discharged and are accumulated, and are caused extremely serious environment and are asked
Topic.
For devitrified glass majority currently on the market using natural minerals or pure chemicals as primary raw material, production cost is high,
Raw material reserves are relatively low, and cinder microcrystalline glass mainly coordinates a small amount of additive to be produced using various trade wastes,
It is of low cost, raw material rich reserves, while solving the environmental problem that waste residue is brought.
With the continuous growth of China's economy, industrial aluminium is all increasing with the trend of straight line every year, therefore produced
Aluminium ash be also very more, aluminium ash is listed in solid dangerous waste, is because the leachate of aluminium ash has certain exceed normally
The toxicity of value.For aluminium ash to the pollution that the main pollution of environment is fluorine, the fluorinated volume in aluminium ash exceeds 3~4 times of normal specified value.
A large amount of fluorine element can cause underground water seriously to pollute in aluminium ash, people and animals drink after can body is caused to seriously affect, fluorine and
The main component calcium of skeleton reacts, and destroys the calcium content of bone, causes calcium deficiency, bone is soft, loss of tooth etc..Aluminium ash is right
Environment can also cause the pollutions such as dust, ammonia, aluminium ash to meet water in alkalinity, can destroy soil acidity or alkalinity.Aluminium in aluminium ash is carried out
Recycling is refined, harm caused by aluminium ash can not be fully solved, and aluminium ash can not only be efficiently used by being used to prepare devitrified glass
In pure aluminum, while also can effectively solve other pollutants in aluminium ash, reduce environmental hazard caused by aluminium ash.
Aluminium ash is electrolytic aluminium or casts product of the slag generated in aluminium production technology after supercooling is processed, wherein by gold
The mixture composition for belonging to aluminium simple substance, oxide and salt solvent, a degree of pollution is caused to ecological environment.Pass through composition detection
It was found that the main component of aluminium ash is：Al2O3(50~75%) and Na2O (8~12%) etc..
Invention content
The method that aluminium ash is main material production nepheline glass ceramic is utilized the purpose of the present invention is to provide a kind of.
The invention is realized in this way：
A method of using aluminium ash be main material production nepheline glass ceramic, include the following steps：
