摘要
本文以贵州龙水磷矿石为原料,通过单因素实验和正交实验,得到脲硫酸分解龙水磷矿石的最佳工艺条件:以ZD-3为活化剂,反应温度为80℃,搅拌速度为650r/min,酸解剂配比为3.0∶1,反应时间为20min,转化率达到90%,可制得优质的脲硫酸复肥。
Longshui phosphate ores in Guizhou were used to produce high quality urea sulfuric acid compound fertilizer, the optimal process conditions were obtained by single-factor experiments and orthogonal experiments. When the active agent was ZD-3, reaction temperature was 80 C, stirring speed was 650 r/ min, mole ratio of urea to sulfuric acid was 3.0 ： 1, reaction time was 20 min, the decomposing rate of phosphate ore Could be about 90%.
