Description
Technical field
The present invention relates to building material technical field, it particularly relates to a kind of imitation wood grain decorative plate 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 production enterprise is every every year secondary
Produce ardealite and be about 3,500,000 tons.So many ardealite not only needs a bigger slag tip, but also water source can be caused dirty
Dye.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 to backfill mine working
Time, mine working filling cost accounts for the 1/3 of mining, and attal accounts for the 80% of filling cost, fills ore deposit with ardealite
Mountain roadway, fills cost and accounts for the 1/5 of mining cost, not only saved filling cost, and improve utilization of three wastes rate, reduce
Environmental pollution.But, owing to ardealite gellant casting resin viscosity is high, sedimentation is fast, it is fast to condense, fine grained plugging many, easy, difficulty
The factors such as cleaning, at present, conventional method is to use mixed material workshop by distance Automobile Transportation to mining area, hole, ore deposit nearby
Set up Filling Station, complete filling with transport pump 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 that common double-bridge vehicle is without sealing easy airborne dust, fortune phosphorus
Though the car of gypsum gel agent is that with the presence of sealing but vehicle body length drives bigger road transport and traffic on sky way to tank car
Potential safety hazard, and ardealite gellant warehouse-in forklift has bad luck, sieves and be filled with airborne dust and noise, to environment with slurry, personnel, sets
For all there is bigger safety and pollution hidden trouble.Using pipeline transportation, Filling Station is because of its ardealite and ardealite gellant proportioning
Ratio and conduit slope, camber, material design are selected unreasonable, blocking pipeline often occurs, causes equipment superpressure, motor super negative
Only destructive dismounting cannot be cleaned after the equipment safety operation hidden danger such as lotus and line clogging, pipeline waste is bigger, relatively costly,
Continuous production is low, equipment and personnel exist bigger safety in production and run hidden danger.
Second method: ardealite is produced Flocculated Cement agent.The crystal habit of ardealite is identical with the natural gypsum, for rib
Shape or cylindricality plate crystal, chemical composition and natural gypsum composition basic simlarity, but due to containing solubility phosphorus pentoxide, phosphorus
Hydrochlorate, soluble fluoride, insoluble phosphorus pentoxide and organic impurities etc., can extend the hydration time of cement, reduce early
Phase intensity and extend setting time, therefore ardealite can not be directly used as the retarder of cement.Need to carry out ardealite
Processing, at present conventional method is ardealite is scrubbed, pretreatment, be dried and the PROCESS FOR TREATMENT such as calcining, and this method obtains cement
Retarder low cost, but by the long flow path of producing cement retarder through phosphogypsum, equipment investment is big, and in the flocculant produced still
Inevitably contain phosphorus pentoxide and fluoride, make the hydration time of cement and setting time longer.
The third method: by ardealite sulfur ammonium and calcium carbonate, the method is to utilize ammonia and carbon dioxide to be turned by ardealite
Chemical conversion sulfur ammonium and calcium carbonate, the method is higher to the prescription of ardealite, and production procedure is long, and investment is big.
4th kind of method: be used for improveing basic soil by ardealite.Containing phosphorus pentoxide in ardealite, cause ardealite
Aobvious acidity, its pH value is 1.5～4.5, can be used to the alkalescence in sweetening of the soil, and ardealite contains phosphorus, ferrum, magnesium, silicon,
The compositions such as zinc, sulfur and calcium are the necessary nutrients of plant growing.

The raw material of standby imitation wood grain decorative plate, by this approach can substantial amounts of process ardealite, and can preferably ardealite be combined
Close and utilize.At present, after generally ardealite being mixed with a small amount of cement, paper pulp, fibre reinforced materials etc., then make after pressurization
Ardealite fibre board, owing to ardealite itself does not have gelling, water content height and contains the characteristics such as plurality of impurities, using should
The performances such as the wearability of ardealite imitation wood grain decorative plate of method production, weatherability, comprcssive strength are on the low side, it is difficult to reach building dress
The use requirement of exterior material.The patent application that ardealite is used for preparing imitation wood grain decorative plate has a lot, such as, and patent
CN101219881 discloses a kind of phosphogypsum composite material, and it is with ardealite and Lauxite as primary raw material, is aided with phenolic aldehyde
Resin, walnut shell, polyacrylamide, 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 " a kind of imitative graining utilizing industrial residue to produce
Plate ", it is in parts by weight, by ardealite 10～40 parts, Calx 5～15 parts, cement 15～28 parts, waterglass 0.02～0.05
