Description
Technical Field
The invention belongs to the technical field of building materials, relates to a resource utilization method of industrial solid waste, and particularly relates to an aluminum ash light brick and a preparation method thereof.
Background
The aluminum ash (also called aluminum slag ash or aluminum slag) is a kind of dross generated in the primary and secondary aluminum industrial production, is the main loss part of liquid raw aluminum in the electrolytic aluminum production, mainly comes from infusible inclusion floating on the surface of aluminum melt in the casting process, additive and substance generated by physical and chemical reaction with the additive, and is in loose ash shape. The aluminum ash produced during the liquid primary aluminum processing process generally contains 30-70% of metallic aluminum, and is generally called lime or primary aluminum ash, and can be used as a raw material for secondary aluminum industrial production. The secondary aluminum industry is primarily concerned with the recovery of aluminum from various wastes (e.g., primary aluminum ash, aluminum scrap, etc. from aluminum processing). The waste produced by the secondary aluminum industry typically contains 5% to 20% metallic aluminum and a large amount of soluble salts, commonly referred to as black ash. The aluminum ash contains a plurality of substances which are directly or indirectly harmful to the environment, and the direct discarding can cause environmental pollution; the aluminum ash is a renewable resource with comprehensive utilization value, and secondary energy sources such as aluminum, salt, aluminum oxide and the like can be recycled from the aluminum ash; it can also be used as raw material for refractory material, road and building material, and desulfurizing agent for steel-smelting.
The bricks traditionally used in the construction industry are mostly formed by evenly stirring clay and other auxiliary materials and then forming the mixture by a briquetting machine and then firing the mixture. Traditional brick is heavier when building a wall, and is hard when building a wall, and the inevitable bearing burden that has increased the building, and the wall that this brick was built simultaneously gives sound insulation, keeps warm, the effect of taking precautions against earthquakes is poor, and anti-seismic performance is low. In addition, the preparation raw materials need a large amount of clay, which has great negative effects on natural resources and ecological balance.
As a result, the brick sintered by the aluminum ash has more porous structures, compared with the traditional solid brick, the weight of the aluminum ash light brick is only 60% -70%, the density is obviously reduced, and compared with the hollow brick, the brick has the advantages of compact structure and good strength. The reactive aluminum nitride contained in the aluminum ash raw material is decomposed after high-temperature sintering, and the nitrogen and other halogen elements in the reactive aluminum nitride are volatilized in a gas form, so that the dangerous characteristic of the aluminum ash is eliminated. In addition, the aluminum ash sintered brick has a porous structure, has the effects of sound insulation, noise reduction, heat preservation and shock resistance when being used for building walls, is particularly suitable for non-bearing walls of commercial places and entertainment places, and is an excellent building brick.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to provide an aluminum ash lightweight brick and a preparation method thereof, the lightweight brick taking aluminum ash as a main raw material has lower density and higher strength, can effectively reduce the load bearing of a building, and has good heat preservation and sound insulation effects due to a uniform pore structure, so that the lightweight brick replaces a clay brick or a common lightweight brick to a certain extent as a novel building material.
The invention uses fine aluminum ash to sinter high-strength light bricks, wherein the aluminum ash contains high aluminum oxide. The high-strength light-weight brick is prepared by ball milling the aluminum ash, winnowing and screening to obtain the aluminum ash with proper particle size, mixing the aluminum ash with the fly ash, the mineral powder and the auxiliary agent, and sintering.
The purpose of the invention is realized by the following technical scheme:
an aluminum ash light brick is prepared from the following raw materials in parts by weight:
preferably, the aluminum ash is ball-milled, and the ball-milling process parameters are as follows: the ball milling revolution is 300 and 2500 revolutions per minute, and the ball milling time is 0.5 to 2 hours; then passing through a wind separation sieve, the particle size is 200-400 meshes.
Preferably, the particle size of the fly ash is 300-600 meshes, and the content of alumina is lower than 35 wt%.
Preferably, the ore fines are of the type S75, S95 or S105 ore fines.
Preferably, the auxiliary agent is fluorite tailing slag or boric acid.
According to the invention, the fluorite tailing slag or boric acid is added, so that the sintering temperature of the light brick can be effectively reduced, and the pore density of the light brick can be increased.
The invention also provides a preparation method of the aluminum ash light brick, which comprises the following steps:
(1) uniformly mixing the aluminum ash, the mineral powder, the fly ash and the auxiliary agent in a stirring tank according to a set proportion to obtain a mixture;
(2) pouring the mixture into a mold, pressing and molding the material through a static pressure machine, delivering the molded material into a sintering kiln, sintering at the temperature of 900-1050 ℃, cooling, and demolding to obtain the aluminum ash light brick.
The invention has the advantages and effects that:
the invention takes the aluminum ash as the main raw material, the aluminum ash generates weak reaction with water at normal temperature, and can release gases such as ammonia gas and the like at high temperature to form uniform air holes in the material, thereby effectively reducing the density of the material.
The aluminum ash is mixed with the fly ash and the mineral powder, then the sintering temperature is further reduced and the pore density of the light brick is increased under the cooperation of the auxiliary agent, so that the aluminum ash light brick with lower density and higher strength can be obtained.
Compared with the traditional clay brick, the light brick taking the aluminum ash as the main raw material has lower density and higher strength, and can effectively reduce the bearing of a building, thereby replacing the clay brick or the common light brick to a certain extent as a novel building material.
