Background technology
The refractory materials kind is a lot, forms main minute six classes: soil, stone, sand, ore deposit, powder and other materials.
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 wilkinite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
With the volcanoclastic rock that also has of attapulgite clay ore deposit symbiosis, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area
'sthickness is up to tens of rice, at attapulgite clay in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, investigates factually, 1 ton of attapulgite clay of every exploitation, the volcanoclastic rock produced has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock of generation, 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, causes the serious wasting of resources and financial loss.
Summary of the invention
The objective of the invention is to overcome weak point in prior art, provide a kind of Attapulgite volcanoclastic rock heat insulation raw meal powder.
The heat insulation raw meal powder of Attapulgite volcanoclastic rock is comprised of the sticky attapulgite clay powder of height, attapulgite clay mine tailing, volcanoclastic rock mixture, pearlstone, diatomite mine tailing and wilkinite mine tailing.
The production method of the heat insulation raw meal powder of Attapulgite volcanoclastic rock: the batching of the heat insulation raw meal powder of Attapulgite volcanoclastic rock is stirred and pulverized, be packaged as the finished product of the heat insulation raw meal powder of Attapulgite volcanoclastic rock.
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, when wet, tool viscosity and plasticity-, be conducive to the bonding between raw material.
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, as a kind of mine tailing, abandons, and causes a large amount of wastings of resources, and the present invention selects the particle fineness of attapulgite clay mine tailing≤2.0 millimeters.
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 (diameter is greater than 100 millimeters), volcanic gravel (diameter is greater than 2 millimeters) and volcanic ash (diameter is less than 2 millimeters), the volcanoclastic rock main chemical compositions is silicon-dioxide and aluminum oxide, have fire performance preferably, the present invention selects the particle fineness of volcanoclastic rock mixture≤5.0 millimeters.
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 present invention selects the particle fineness of pearlstone≤2.0 millimeters.
Diatomite is fine and smooth, loose, light weight, porous, specific surface area is large, space is regular distribution, and stable chemical nature is a kind of natural nano aperture amorphous silicon material, but diatomite is made a low multiple use, the product of most enterprises comes from one-level soil, and two, three grades of soil are discarded in a large number, have caused serious waste of resources, also polluted environment, the present invention selects the particle fineness of diatomite mine tailing≤2.0 millimeters.
The rock that wilkinite mainly is comprised of montmorillonite, it is the important raw mineral materials of field of metallurgy, the wilkinite mine tailing that the present invention selects is distributed in the lower floor in attapulgite clay ore deposit mostly, be difficult to carry out independent exploitation, but the content of aluminum oxide >=16% in the wilkinite mine tailing, and thering is plasticity-and agglutinating value(of coal), the present invention selects the particle fineness of wilkinite mine tailing≤2.0 millimeters.
The present invention is achieved by following technical proposals:
1, the batching of the heat insulation raw meal powder of Attapulgite volcanoclastic rock is comprised of following component by weight percentage: high sticky attapulgite clay powder 2~15%, attapulgite clay mine tailing 5~25%, volcanoclastic rock mixture 10~40%, pearlstone 5~40%, diatomite mine tailing 2~15% and wilkinite mine tailing 2~15%;
The production method of the heat insulation raw meal powder of described Attapulgite volcanoclastic rock: the batching of the heat insulation raw meal powder of Attapulgite volcanoclastic rock is added in the two shaft pugmill mixer moved and stirs, stirring, to pulverize in rear input pulverizer be the work in-process of the heat insulation raw meal powder of Attapulgite volcanoclastic rock, the half-finished particle fineness of the heat insulation raw meal powder of Attapulgite volcanoclastic rock≤0.15 millimeter, be packaged as the finished product of the heat insulation raw meal powder of Attapulgite volcanoclastic rock.
The heat insulation raw meal powder of Attapulgite volcanoclastic rock has that sticking power is good, the characteristics of sound-insulating and heat-insulating and fire protection flame retarding.
In the batching of the heat insulation raw meal powder of Attapulgite volcanoclastic rock, the various wastes of a large amount of employing, not only be conducive to improve resource utilization, turns waste into wealth, and can also reduce land occupation, and protection and environment purification are saved the energy, reduce production costs, and increase economic efficiency.
The heat insulation raw meal powder of Attapulgite volcanoclastic rock is applicable to the fire-proof and thermal-insulation concrete and builds the insulating refractory engineering by laying bricks or stones.
