Abstract

The invention relates to fertilizer and in particular relates to instant potassium ammonium phosphate. Specifically, the instant potassium ammonium phosphate is prepared from raw materials including potassium chloride, ammonium bicarbonate, completely water-soluble ammonium dihydrogen phosphate and chelated microelements; a specific production process of the instant potassium ammonium phosphate comprises the following steps: grinding the potassium chloride, the ammonium bicarbonate, the completely water-soluble ammonium dihydrogen phosphate and the chelated microelements into powder; adding the ammonium bicarbonate into water and adding phosphoric acid to regulate the pH (Potential of Hydrogen) value to 6 to 7; continually adding the phosphoric acid to regulate the pH value to 3 to 5; adding the potassium chloride and sufficiently stirring; adding the residual ammonium bicarbonate and standing at 18 DEG C to 25 DEG C for 24h to 36h; filtering; carrying out solid-liquid separation and drying solids; uniformly mixing the solids with the chelated microelements and packaging a mixture to obtain a finished product.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an instant potassium ammonium phosphate. Background technique [0002] Instant potassium ammonium phosphate is a solid solution composed of potassium dihydrogen phosphate and ammonium dihydrogen phosphate in different proportions. It is a high-concentration nitrogen, phosphorus and potassium compound fertilizer, and its total nutrient content can generally reach about 70%. [0003] At present, the technological processes for preparing instant potassium ammonium phosphate are: phosphoric acid, potassium chloride ammonification process and direct method ammonification process. The former is represented by Israel's IMI process. Although it was patented earlier, it has not been reported on industrialization so far. The direct ammonification process is a newly developed method, and the cost of instant potassium ammonium phosphate fertilizer produced by this method is very high. Contents of the inven...
