Description
Technical field
The present invention relates to a kind of preparation method of autoclaved brick, particularly a kind of method of utilizing smelting magnesium slag and fly-ash Preparation autoclaved brick.
Background technology
China is one of main coal producer in the world, and the main energy sources of long duration at present and in the future that coal is China verifies at primary energy source that coal accounts for 90% in the total amount; Though country greatly develops water power, nuclear power, coal fired power generation is still occupied an leading position.Flyash is the industrial residue in fuel-burning power plant, and along with the fast development of China's power industry, fuel-burning power plant flyash quantity discharged increases rapidly year by year, and nearly 400,000,000 tons by 2009, the flyash that accumulative total is stored up reaches more than 50 hundred million tons.Flyash is heaped not only will take a large amount of soils, the cost substantial contribution is taken over the land for use, builds a dam and is managed, cause huge pollution to surrounding environment simultaneously, influence the work and the life of surrounding resident, sometimes even the security of the lives and property of entail dangers to surrounding resident, caused immense pressure for economic construction and ecotope.So how to realize a large amount of utilizations of flyash, it is the key subjects that people study that flyash is turned waste into wealth.Utilizing flyash to produce autoclaved brick at present is a kind of mature technology that can utilize flyash in a large number, and its technical formula is generally flyash, aggregate, unslaked lime and gypsum etc.
In the magnesium metal smelting industry, Pidgeon process is the main method of refining magnesium, and China's former magnesium output the first in the world accounts for 75% of world wide production, and every production 1 t MAGNESIUM METAL is just discharged 8 t left and right sides magnesium slags.The quantity discharged of China's magnesium slag has reached millions of tons at present, and along with the fast development of refining magnesium industry, the quantity discharged of magnesium slag also can increase year by year; Yet the utilization ratio of China's magnesium slag is but very low, the rivers that a considerable amount of magnesium slags are abandoned is arranged or take the farmland, contaminate environment.Utilize smelting magnesium slag to produce the few of material of construction, utilize the common prescription of smelting magnesium slag brickmaking to be magnesium slag, aggregate, lime, gypsum etc. in some documents of report.
Above-mentioned two kinds of main waste solids are produced the massfraction that all needs in the prescription of bricks to mix greater than 10% lime; As everyone knows, lime industry belongs to high energy consumption, high pollution industry, and its pollutent is principal character with the dust pollution; According to relevant documents and materials introduction; ten thousand tons of standard coals surplus the annual consumption about 3000 of China's lime production; ton lime production energy consumption is marked coal greater than 180kg; and pollutant discharge amounts such as dust are surprising especially; and lime industry mass-producing enterprise is less, mostly is small-sized private business, is the local market product is provided; so comparatively difficulty is used in the less area of some lime mine resources, the lime price is corresponding higher.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing smelting magnesium slag and fly-ash Preparation autoclaved brick, adopting smelting magnesium slag and flyash is raw material, does not add under the situation of lime and prepares autoclaved brick, can either utilize solid slag, can reduce pollution again, reduce production costs simultaneously.
Method of the present invention is carried out according to the following steps:
1, adopt smelting magnesium slag, flyash and aggregate as basic material, smelting magnesium slag, flyash and aggregate are mixed, wherein smelting magnesium slag accounts for 10 ~ 30% of whole basic material gross weights, and flyash accounts for 50 ~ 70% of whole basic material gross weights, and aggregate accounts for 10 ~ 30% of whole basic material gross weights; Add exciting agent and water in whipping process, wherein exciting agent accounts for 0.1 ~ 5% of whole basic material gross weights, and water accounts for 10 ~ 20% of whole basic material gross weights, and it is even to be stirred to whole mixing of materials, obtains mixture;
2, mixture is left standstill digest, digestion time is 3 ~ 8h, obtains the digestion material;
3, will digest material and carry out rolling 3 ~ 5min with wheel roller, and use brick pressing machine compression moulding then, forming pressure is 25 ~ 45MPa, and the 1 ~ 5h that rests then obtains adobe;
4, adobe is placed in the autoclave, steam press maintenance 3 ~ 10h under 150 ~ 200 ℃ of vapour temperatures and vapor pressure 0.6 ~ 1.2 MPa condition makes autoclaved brick.
Exciting agent in the aforesaid method is one or more the mixture in water glass, gypsum, trolamine and the cement.
Above-mentioned aggregate is the rubble of particle diameter 2 ~ 4mm.
Dual horizontal axle forced mixer is adopted in stirring in the aforesaid method, and stirring velocity is 46r/min, and churning time is 2 ~ 5min.
Method technology of the present invention is simple, grasp easily, production cost is low, the cycle is short, high efficiency; The autoclaved brick that obtains meets the standard of national building materials with brick, is suitable for industrializing implementation; This method does not adopt unslaked lime as raw material, adds exciting agent in mixing process, is not subjected to the influence of unslaked lime supply, can realize the large-scale production to extensive solid waste, has reduced environmental pollution.
