系统介绍了以碳酸氢铵为主要原料,配以适量尿素和铵离子复合稳定剂、防结块剂等,在常温下,采用干法(无需添加黏结剂,无需烘干过程)造粒工艺制备多元素长效碳铵颗粒肥的工艺方法,并进行了性能实验和效益分析以及推广应用的前景预测.%This paper systematically introduces the way how to make ammonium bicarbonate as main raw materialsinto multi-element long-acting granular ammonium bicarbonate at room temperature,together with right amounturea, ammonium composite stabilizers, and anticaking agents. The granulating process preparation is dry (withoutadding binder,no need drying process). The performance test and benefit analysis,and application prospects weredone.
