Description
Technical field
The present invention relates to a kind of ardealite processing method, especially a kind of micronization modified method of simple ardealite.
Background technology
Ardealite is the solid waste of Phosphate Fertilizer Industry, generally often produces 1 ton of phosphoric acid and about generates 5-6 tons of ardealites, often gives birth to
1 ton of Diammonium phosphate (DAP) of production discharges 2.5-5 tons of ardealites.Currently, no matter external or domestic, the comprehensive utilization ratio of ardealite all compares
It is low, it is main to be handled by the way of stockpiling.China's ardealite adds up nearly hundred million tons of discharge capacity, is discharge capacity maximum one in gypsum offscum
Kind, the phosphogypsum slag of discharge occupies a large amount of soils, forms slag mountain, seriously pollutes environment.
The yield of ardealite is very big at present, but its utilization rate is very low.The reason for causing ardealite utilization rate low has very much, but
Most importantly ardealite surface property is poor, causes its utilization ways relatively simple.By the performance to ardealite micro mist into
Row analysis and understanding, this researcher explores a kind of method of modifying of simple, the lower-cost ardealite micro mist of equipment, to change
It has been apt to the surface property of ardealite micro mist, and then has expanded the comprehensive Utilization Ways of ardealite.

Beneficial effects of the present invention
1, ardealite micro mist is modified processing, the superficiality of modified obtained ardealite micro mist by the present invention by the above method
It can be greatly improved, extend its application in industrial aspect, improve the utility value of ardealite.Conventional process side
There are agglomeration, 45 microns of testing sieve residue on sieves to be typically larger than 3%, while activation grade matter for modified ardealite micro mist made from method
It is relatively low to measure score.Modified ardealite micro mist produced by the present invention is tested with 45 microns of testing sieves, residue on sieve≤1%, activation grade matter
Score >=90% is measured, oil absorption≤66mL/100g is met the requirements of the standard, and can be used as the prepared filler of the plastic products such as PVC, PP makes
With.
2, for method of the invention in processing, equipment requirement is low, simple for process, and cost is relatively low, but the effect reached is very
Obviously.
