Technological development and industrialization of new type sulfur enhanced monoammonium phosphate products
In response to key technical issues such as soil sulfur deficiency,coarse and uneven distribution of sulfur particles in sulfur enhanced monoammonium phosphate fertilizers,and poor crop absorption,micron scale sulfur preparation technology,and key technology of new sulfur-contained monoammonium phosphate products are studied.Industrialization technology transformation has been carried out based on diammonium phosphate(DAP)devices,a new type of sulfur enhanced monoammonium phosphate products are produced with wet concentrated phosphoric acid,liquid ammonia and liquid sulfur as the main raw materials,with 90%sulfur particle size≤75 μ m and sulfur microparticles are distributed evenly in sulfur enhanced monoammonium phosphate,which can effectively promote the rapid transformation of sulfur particles in soil and meet the sulfur demand of plants during the whole growth period.
