Description
Technical field
The present invention relates to building material field, be specifically related to a kind of production method of unburned Attapulgite bed-silt warming plate.
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.
China is for administering the water quality deterioration of harbour, navigation channel, lake and river water, to take dredging engineering mostly, the bed-silt amount that dredging engineering produces increases day by day, the moiety complexity, easily produce secondary pollution, deal with improperly and will cause totally unfavorable impact to environment, thereby the processing of dredging bed-silt has just been become to people's question of common concern.
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 production method of unburned Attapulgite bed-silt warming plate is provided.
The production method of unburned Attapulgite bed-silt warming plate: the batching of unburned Attapulgite bed-silt warming plate process is stirred, be pressed into difform unburned Attapulgite bed-silt warming plate work in-process, according to the conventional maintenance process maintenance of cement products, be packaged as the finished product of unburned Attapulgite bed-silt warming plate after 28 days.The batching of unburned Attapulgite bed-silt warming plate is by attapulgite clay mine tailing, bed-silt, volcanoclastic rock mixture, wilkinite mine tailing, flyash, pearlstone and cement composition.
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, and can improve intensity and the porosity of unburned Attapulgite bed-silt warming plate.
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.
Bed-silt is to have abandoned or concentrated the mud of stacking in the engineerings such as dredging harbour, navigation channel, lake and river, and the bed-silt water ratio that the present invention selects is less than 20%, particle fineness≤5.0 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 unburned Attapulgite bed-silt warming plate, the present invention selects the volcanoclastic rock mixture after pulverizing, particle fineness≤3.0 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.
Flyash can increase the porosity of unburned Attapulgite bed-silt warming plate, and the present invention selects the flyash after pulverizing, particle fineness≤0.25 millimeter.
Pearlstone be perlite ore through preheating, the material of the white granular that a kind of inside of making after the TRANSIENT HIGH TEMPERATURE calcining expansion is polynuclear plane.The characteristics such as pearlstone has that apparent density is light, thermal conductivity is low, chemical stability is good, the use temperature scope is wide, wettability power is little, nontoxic, tasteless, fire prevention and sound-absorbing, the particle fineness of pearlstone after the present invention selects and pulverizes≤0.25 millimeter.
The cement selection silicate cement.
