Title: Preparation method of high - efficiency magnesium polyphosphate fertilizer
Inventor: GUICHUAN WANG
IPC: C05B11/10
Filed: 2022-04-05
Granted: 2023-10-10
Abstract: The invention belongs to the field of fertilizers, and specifically discloses a preparation 5 method of a high - efficiency magnesium polyphosphate fertilizer, which comprises the following steps: (1) adding wet - process phosphoric acid as a raw material into a vacuum distillation device for distillation; (2) polymerizing the distilled phosphoric acid solution with phosphorus pentoxide; (3) mixing the material treated in step (2) with magnesium - containing compound powder and adjusting the pH value; and (4) adding succinic acid diethyl aminoethanol citrate and mixing 10 evenly to obtain the required high - efficiency magnesium polyphosphate fertilizer. The invention uses wet phosphoric acid to produce magnesium polyphosphate fertilizer and adopts polyphosphate technology, which more than doubles the effectiveness of phosphorus, and the fertilizer has stable quality and good controlled release performance. The polyphosphate in the fertilizer has the ability to chelate metal ions and can be absorbed by plants by forming soluble 15 complexes with ineffective trace elements in the soil; at the same time, the chelating effect of the polyphosphate prevents the formation of precipitation of metal impurities in the suspended fertilizer, thus adding polyphosphate can result in a highly concentrated suspended fertilizer.
