尿素产品的检验依据,按照国家标准GB2440-2001《尿素及其测定方法》Ureaanditsdetermination严格执行,影响尿素产品优级品率的主要原因是缩二脲和水分含量。在生产车间从工艺、设备、操作方面不断优化,保证生产稳定运行的基础上,探讨如何通过准确的分析检验的全过程控制来提供准确数据,确保检验质量,使分析检验的准确率大于99%,及格率达到100%,从而不断提高尿素产品的优等品率。 The test basis of urea products, according to the national standard GB2440-2001 “urea and its determination method” Ureaanditsdetermination strictly enforced, the main reason affecting the urea product excellent grade rate is biuret and moisture content. On the basis of constant optimization of technology, equipment and operation in the production workshop to ensure the stable operation of production, this paper discusses how to provide accurate data through accurate analysis of the whole process control and ensure the quality of inspection so that the accuracy of analysis and inspection is more than 99% , Passing rate of 100%, so as to continuously improve the excellent products of urea products rate.
