Monoammonium磷酸盐

Monoammonium Phosphate Brief description of production process: Adopt advanced tubular reactor process for production. After the Phosphate rock (plasma) reacted with sulphuric acid, carry out liquid solid separation to obtain wet phosphoric acid which shall concentrated to be concentrated phosphoric acid.After the neutralization reaction between liquid ammonia and phosphoric acid:Spray Reaction slurry on the return products for material manufacture, and carry out drying, screening, anti-caking packages, cooling and other processes to obtain granular product; Carry out sponging drying, screen separation, anti-caking package and cooling for reaction slurry to get powdered product. Main technical indicators:NH4H2PO4 (ammonium dihydrogen phosphate) ≥99% P2O5 (phosphorus pentoxide) ≥61% N (Nitrogen)≥12% PH: 4.4-4.6 Water insoluble ≤0.1% Water content ≤0.2% Executive Standard: (GB10205-2001) Appearance: white or light-colored powder, no obvious crystallization phenomenonProtection measures for transport and storage: In order to prevent agglomeration affected with damp and deteriorative change, put the products in door or cover them with tarpaulin, while avoiding the exposure under sunlight.Other description: powdered monoammonium phosphate which made from high-quality phosphate with concentration method of phosphoric acid is Grade I product, and the one made from low and middle grade phosphorite with high content of Mg, Fe and Al with slurry concentrating process is Grade II product.
