摘要:

针对云南某企业生产的全水溶性66%磷酸一铵在储存过程中出现结块的问题,提出了在磷酸一铵浓缩清液中加入防结块剂达到防结块效果的研究思路。结合结块性能快速测定方法,开展了实验室研究开发,获得了具有最佳防结块效果的防结块剂,并进行了工业实验验证。实验研究结果表明:在磷酸一铵浓缩清液中加入质量分数为0.05%的防结块剂十八胺,能有效改善全水溶性66%磷酸一铵的结块问题,且添加防结块剂后对产品质量没有影响;工业实验中获得的磷酸一铵产品均能达到HG/T 5048—2016《水溶性磷酸一铵》中Ⅱ型的质量要求。

Abstract:

In order to solve the problem of caking in the storage process of 66% water-soluble monoammonium phosphate of an enterprise in Yunnan,the research idea of adding anti-caking agent into monoammonium phosphate concentrated clear li-quid to achieve anti-caking effect was put forward.Combining with the rapid determination method of caking performance,laboratory research and development were carried out,and the anti-caking agent with the best anti caking effect was obtained,which was verified by industrial test.The test results showed that adding 0.05% anti-caking agent octadecylamine into monoammonium phosphate concentrated clear liquid could effectively improve the caking problem of 66% water-soluble monoammonium phosphate,and the addition of anti-caking agent had no impact on the product quality;the products obtained in industrial test could meet the industry standard HG/T 5048—2016 quality requirements of type Ⅱ in water soluble monoammonium phosphate.

Key words: water soluble monoammonium phosphate, caking, anti-caking agent
