Description
Technical field:
[0001] The invention relates to a triammonium phosphate compound fertilizer and its preparation technology. Background technique:
[0002] At present, the raw materials for various compound fertilizers (mixed fertilizers) used for crops mainly include potassium chloride, potassium sulfate, monoammonium phosphate, diammonium phosphate, superphosphate, ammonium chloride, ammonium bicarbonate, urea, etc. In order to produce fertilizers with a total nutrient content of more than 50%, it is necessary to adopt a method of increasing the ratio of ammonium phosphate to be used. In order to meet the actual needs of crop growth, simply relying on urea to increase the content of single nutrient nitrogen obviously cannot meet the requirements of scientific formula fertilization. At the same time, due to the compound fertilizer (mixed fertilizer) produced by the traditional granulation method, because the granulation process belongs to simple physical adhesion, the stru...
