Technical Field

[0001] The utility model relates to the technical field of ammonium polyphosphate preparation devices, in particular to an ammonium polyphosphate preparation device. Background Art

[0002] Ammonium polyphosphate, abbreviated as PPA, is a polymer formed by multiple phosphate ions and ammonium ions. It is a colorless and transparent crystal with good water solubility and thermal stability. It is an efficient, safe and environmentally friendly fertilizer. Ammonium polyphosphate can be quickly absorbed and utilized by crops, which can effectively increase crop yield and quality, increase plant leaf area, stimulate plant growth, and improve photosynthesis efficiency.
