Description
Technical field
The present invention relates to building material field, be specifically related to a kind of attapulgite coal ash insulating brick.
Background technology
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, make Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area caused to serious threat.
Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
The volcanoclastic rock that also has with the symbiosis of attapulgite clay ore deposit, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the thickness of the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area is up to tens of rice, attapulgite clay is in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, investigate factually, the volcanoclastic rock that 1 ton of attapulgite clay of every exploitation produces has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock produced is up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, cause the serious wasting of resources and financial loss.
Flyash is to receive the thin ash of catching in the flue gas from coal combustion, flyash is also the main solid waste that coal-burning power plant discharges, be one of industrial residue that the current discharge capacity of China is larger, along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; If enter water system, can cause river to silt up, toxic chemical substance wherein also can work the mischief to human body and biology.
Summary of the invention
The objective of the invention is to overcome weak point in prior art, a kind of attapulgite coal ash insulating brick is provided.
The batching of attapulgite coal ash insulating brick is comprised of the sticky attapulgite clay powder of height, attapulgite clay mine tailing, volcanoclastic rock mixture, flyash, wilkinite mine tailing, diatomite mine tailing and straw powder.
The production method of attapulgite coal ash insulating brick: the batching of attapulgite coal ash insulating brick, through stirring, is pressed into to difform attapulgite coal ash insulating brick work in-process, is transported to the finished product that tunnel kiln sintering becomes attapulgite coal ash insulating brick.
Attapulgite clay be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, attapulgite clay soil property exquisiteness, water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, can improve intensity and the porosity of attapulgite coal ash insulating brick.
High sticky attapulgite clay powder refers to gets 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, the suspension cup is placed on homogenizer, under the rotating speed of 11000 rev/mins, stir 20 minutes, to pour in the beaker of 250ml through the high-speed stirring sample suspension again the viscosity of using NDJ-1 type rotational viscosimeter to be tested its suspension, tested viscosity value>=2200 into
mPasthe attapulgite clay powder be high sticky attapulgite clay powder, the height that the present invention selects glues attapulgite clay powder particles fineness≤0.074 millimeter.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, can't be sieved, and as a kind of mine tailing, abandons, and causes a large amount of wastings of resources, and the present invention selects the attapulgite clay mine tailing after pulverizing, particle fineness≤0.149 millimeter.
Volcanoclastic rock is the rock of the transitional type between magma lava and sedimentogeneous rock, wherein the composition more than 50% is comprised of the material of pyroclastic flow ejection, and these tephras are mainly the lava of premature coagulation on volcano, the rock formation that passage is burst on every side when volcanic eruption.The volcanoclastic rock mixture comprises landwaste, brilliant bits, glassiness bits, slurry bits, volcanic block, volcanic gravel and volcanic ash, volcanoclastic rock can increase the intensity of attapulgite coal ash insulating brick, the present invention selects the volcanoclastic rock mixture after pulverizing, particle fineness≤5.0 millimeter.
The flyash main component is silicon-dioxide, aluminium sesquioxide, ferric oxide, calcium oxide and unburnt carbon, do not fire charcoal and be loose porous form more, can increase the porosity of attapulgite coal ash insulating brick and reduce energy consumption, the present invention selects the flyash after pulverizing, particle fineness≤0.25 millimeter.
Wilkinite has plasticity-and agglutinating value(of coal), and the wilkinite mine tailing that the present invention selects is distributed in the lower floor in attapulgite clay ore deposit mostly, is difficult to carry out independent exploitation, quality is also poor, major part is abandoned in the mine tailing district, and the present invention selects the wilkinite mine tailing after pulverizing, particle fineness≤0.25 millimeter.
Diatomite is fine and smooth, loose, light weight, porous, specific surface area is large, and space is regular distribution, stable chemical nature, it is a kind of natural nano aperture amorphous silicon material, but diatomite is made a low multiple use, most products come from one-level soil, and two, three grades of soil are discarded in a large number, caused serious waste of resources, also polluted environment, the present invention selects the diatomite mine tailing after pulverizing, particle fineness≤0.25 millimeter.
Stalk is the general name of ripe farm crop cauline leaf (fringe) part, is often referred to wheat, paddy rice, corn, potato class, oil plant, cotton, sugarcane and other farm crop remainder after the results seed.It is in order to increase the porosity of attapulgite coal ash insulating brick that the present invention adopts straw powder, attapulgite coal ash insulating brick is in roasting process, and the straw burning in insulating brick is ashes, forms a large amount of micropores, the present invention selects the straw powder after pulverizing, particle fineness≤1.0 millimeter.
