Description
Technical field
The present invention relates to building material technical field, it particularly relates to a kind of artificial grantie wall
Body material and preparation method thereof.
Background technology
In production process of phosphoric acid, often produce one ton of P2O5Five tons of ardealites of by-product, medium-sized phosphoric acid
The every by-product ardealite every year of manufacturing enterprise is about 3,500,000 tons.So many ardealite not only needs
One bigger slag tip, but also pollution of waterhead can be caused.At present, the most frequently used ardealite
Processing method has a following four:
First method: be used for backfilling pit by phosphoric acid cream.According to statistics, it is being provided without ardealite
When backfilling mine working, mine working filling cost accounts for the 1/3 of mining, and attal
Account for the 80% of filling cost, fill mine working with ardealite, fill cost and account for digging up mine into
This 1/5, has not only saved filling cost, and has improve utilization of three wastes rate, decreased ring
Protect and pollute.But, owing to ardealite gellant casting resin viscosity is high, sedimentation is fast, it is fast to condense,
The factors such as fine grained plugging many, easy, difficult cleaning, at present, conventional method is to use mixture
By distance Automobile Transportation to mining area between truck, Filling Station is set up in hole, ore deposit nearby, uses transport pump
Filling is completed to flow processs such as roadways.Automobile Transportation typically has 30 from ardealite storage yard to Filling Station
The distance of km, major part is sky way.The car of transport ardealite is common doube bridge
Though car is without sealing easy airborne dust, the car of fortune ardealite gellant and be that tank car has sealing but vehicle body length being at dish
There is bigger road transport and traffic safety hidden danger, and ardealite gellant in mountain driven on public roads
Warehouse-in forklift has bad luck, sieve and be filled with airborne dust and noise, to environment with slurry, personnel, equipment
All there is bigger safety and pollution hidden trouble.Use pipeline transportation, Filling Station because of its ardealite and
Ardealite gellant ratio and conduit slope, camber, material design are selected unreasonable, warp
Often there is blocking pipeline, cause the equipment safety operation hidden danger such as equipment superpressure, motor overload and
Cannot clean only destructive dismounting after line clogging, pipeline waste is bigger, relatively costly, raw
Producing that seriality is low, there is bigger safety in production and runs hidden danger in equipment and personnel.
Second method: ardealite is produced Flocculated Cement agent.The crystal habit of ardealite and sky
So Gypsum Fibrosum is identical, and for prismatic or cylindricality plate crystal, chemical composition is basic with natural gypsum composition
Similar, but due to containing solubility phosphorus pentoxide, phosphate, soluble fluoride, insoluble
Property phosphorus pentoxide and organic impurities etc., can extend cement hydration time, reduce in early days strong
Spend and extend setting time, therefore ardealite can not be directly used as the retarder of cement.Need
Ardealite is processed, at present conventional method be ardealite is scrubbed, pretreatment,
Being dried and the PROCESS FOR TREATMENT such as calcining, this method obtains cement retarder low cost, but by ardealite
Producing the long flow path of cement retarder, equipment investment is big, and still can not keep away in the flocculant produced
Exempt from containing phosphorus pentoxide and fluoride, make the hydration time of cement and setting time relatively
Long.
The third method: by ardealite sulfur ammonium and calcium carbonate, the method is to utilize ammonia and dioxy
Changing carbon and ardealite changes into sulfur ammonium and calcium carbonate, the method is to the prescription of ardealite relatively
Height, and production procedure is long, investment is big.
4th kind of method: be used for improveing basic soil by ardealite.Containing five oxidations in ardealite
Two phosphorus, cause the aobvious acidity of ardealite, and its pH value is 1.5～4.5, can be used in sweetening of the soil
The compositions such as the phosphorus, ferrum, magnesium, silicon, zinc, sulfur and the calcium that contain in alkalescence, and ardealite are to plant
Thing grows necessary nutrient.
Above-mentioned several method has promoted the technological progress of China's ardealite resource, but above-mentioned technology
Fail sufficiently ardealite to be utilized, and can not fundamentally solve ardealite accumulation such as
The present situation on mountain.Therefore, someone uses phosphogypsum as preparing the raw material of artificial grantie materials for wall,
By this approach can substantial amounts of process ardealite, and preferably ardealite can be carried out comprehensive utilization
With.At present, after generally ardealite being mixed with a small amount of cement, paper pulp, fibre reinforced materials etc.,
Ardealite fibre board is made, owing to ardealite itself does not have gelling, contains again after pressurization
The water yield is high and contains the characteristics such as plurality of impurities, uses the ardealite artificial grantie that the method produces
The performances such as the wearability of materials for wall, weatherability, comprcssive strength are on the low side, it is difficult to reach building dress
The use requirement of exterior material.Ardealite is used for preparing the patent application of artificial grantie materials for wall
Having a lot, such as, patent CN101219881 discloses a kind of phosphogypsum composite material, and it is
With ardealite and Lauxite as primary raw material, it is aided with phenolic resin, walnut shell, polyacrylamide
Amine, flyash, after above-mentioned raw materials mix and blend, then through extruded and get final product, make work
Skill is simple.Patent No. ZL200810233755.0, invention entitled " one utilizes Industry Waste
