Abstract
The invention provides an all-solid waste black glass ceramic and a preparation method and an application thereof. According to the preparation method, 30%-85% of fly ash, 0-30% of carbide slurry, 0-35% of steel slag, 0-35% of red mud and 0-35% of black mud are used as raw materials to prepare a high added-value product all-solid waste black glass ceramic by a high temperature fusion method. Utilization rate of the solid wastes is 100%. The pollution of solid wastes including fly ash, carbide slurry, steel slag, red mud and black mud to the environment is effectively solved. In addition, the prepared all-solid waste black glass ceramic has advantages of bright and black color, high strength and corrosion resistance, and can be used in building and ornament materials, furniture table top, industrial wear-resistant corrosion-resistant materials and handicrafts.
Description
Technical field
The invention belongs to environmental protection and field of new, relate in particular to a kind of full solid waste black glass pottery and preparation method thereof and application.
Background technology
Power Plant in China is taking fire coal as main, it is reported statistics, and within 2010, China's thermoelectricity industry approximately consumes 1,300,000,000 tons, mark coal, nearly 400,000,000 tons of the flyash amounts of generation.Take Shandong Province as example, coal consumption has reached 2.5 hundred million tons, nearly 8,000 ten thousand tons of flyash quantity discharged, the operation of many coal gangues setting up for save energy in fact in recent years and low combustion value electricity generation by coal sludge factory, the quantity discharged of flyash is increased, estimate that total amount exceedes 8,000 ten thousand tons, enormous amount.The stacking of flyash not only will take a large amount of soils, and flyash light weight, particle are little very easily causes environmental pollution.The discharge of a large amount of flyash, has brought very large pressure to refuse processing and environment protection.Governments at all levels all take much count of the processing problem of flyash.
Calcium carbide mud is that the waste residue taking calcium hydroxide as main component after acetylene gas is obtained in calcium carbide hydrolysis.1t calcium carbide adds water and can generate more than 300 kilogram of acetylene gas, generates the industrial effluent of 10t solid content approximately 12% simultaneously, is commonly called as carbide slag slurries, and carbide slag slurries obtains calcium carbide mud after press filtration is processed.Its disposal makes factory's headache always.Slag is the waste residue that Steel industry is discharged, and at present, the slag quantity discharged of China is about crude steel output 15%～20%.According to statistics, China's slag effective rate of utilization is only 10% left and right.The contaminative waste residue of discharging when red mud is Aluminium industry extraction aluminum oxide, 1 ton of aluminum oxide of the every production of average, 1～1.8 ton of red mud of subsidiary generation.Expect 2015, red mud accumulative total volume of cargo in storage will reach 3.5 hundred million tons.At present, China's red mud comprehensive utilization ratio is only 4%.Black mud is to produce the waste residue of discharging after titanium dioxide, and it is acid strong, large to environmental hazard.A large amount of calcium carbide mud, slag, red mud and black mud discharge are piled up and are formed slag mountain, have not only taken a large amount of soils, and also contaminate environment, destroys natural, ecological, brings very large burden to environment and enterprise.
Up to the present, the utilization of flyash is except producing building building block, and brickmaking, makes beyond low-grade concrete, and greatly still for filling out hole, paving the way, its comprehensive utilization ratio is no more than 60%, and some economically less developed region is even lower than 30%.Calcium carbide mud is mainly used for filling out sea, fills out ditch, cement spike etc.Slag is mainly used for road slag stone and stemming operation material, cement additive, lays bricks etc.Red mud is mainly used in materials for wall, pigment, metal recovery etc., and black mud is mainly used in cement additive, aggregate, lays bricks etc.The application majority of above-mentioned solid waste only has social benefit, there is no economic benefit.
Summary of the invention
The object of the present invention is to provide one to utilize the solid waste such as flyash to prepare full solid waste black glass pottery, be not intended to solve the solid waste comprehensive utilization ratios such as flyash, calcium carbide mud, slag, red mud, black mud high and cause the problem of contaminate environment.
Another object of the present invention is to provide the preparation method of above-mentioned full solid waste black glass pottery.
A further object of the present invention is to provide the application of above-mentioned full solid waste black glass pottery.
The present invention is achieved in that a kind of full solid waste black glass pottery porcelain, by being prepared from by mass parts component below:
The preparation method who the present invention further provides a kind of full solid waste black glass pottery, comprises the following steps:
(1) 30%～85% flyash, 0～30% calcium carbide mud, 0～35% slag, 0～35% red mud and 0～35% black mud are evenly mixed, after being placed in High Temperature Furnaces Heating Apparatus heating 1～4h at 1400 DEG C～1600 DEG C temperature, melt and obtain vitreum, regulating temperature is 550 DEG C～650 DEG C annealing 30min～1h, and furnace cooling obtains parent glass;
(2) parent glass step (1) being obtained is placed in heat treatment furnace in moulding, is incubated 1～2h and carries out heat of crystallization processing under the condition of 800 DEG C～1050 DEG C, then coolingly obtains full solid waste black glass pottery.
