摘要
Abstract
We take the wet process phosphoric acid、humic acid and its salts as raw materials,take the american jiajie diammonium phosphate products as reference,and do the dyeing evaluation experiment according to the process conditions of the traditional method of production of diammonium phosphate.This experiment has studied the different types of humic acid and its salts’s solubleness in concentrated phosphoric acid,washing liquid and water resistance;did the ammonia neutralization reaction experiment under the con-dition of different varieties and amount of the colorant.Based on these experiments,we have finished the spray granulation experiments.Experimental study showed that the suitable adding method of the humic acid colorant in the ammonium phosphate production system is that it is formulated in the 10% concentration of a-queous solution,then adding to the phosphate or washing liquid;the product of 0.15% dosage of the ESM-1 colorant is the best,and it’s color is mostly closed to the american jiajie diammonium phosphate products, adding the ESM-1 type colorant doesn’t impact it’s product nutrient,and we can get superior diammonium phosphate product.关键词
