USE
It is an excellent feed additive, which can provide two nutritional elements of phosphorus and non-protein nitrogen (urea nitrogen) for livestock (especially ruminants). It is also a high concentration of nitrogen and phosphorus compound fertilizer, can also be used as flame retardant, metal surface treatment agent, fermentation nutrient agent, cleaning agent and purification of phosphoric acid auxiliaries.
It is obtained by the reaction of wet phosphoric acid and urea solution; It can also be obtained by the reaction of dilute phosphoric acid with urea.
Urea phosphate was prepared by the reaction of urea and phosphoric acid solution, then the solution was concentrated, centrifuged and separated, and dried.
