Difference between agricultural urea and industrial urea.
Analyzed from the point of view of the manufacturer of urea, there is no essential difference between the two, only the content is different.
Industrial urea is already a more mature process, agricultural urea has a slightly higher content of diurea than industrial, and the rest of the composition is about the same. However, it should be noted that in recent years, agricultural urea are pursuing large particles and slow release, many manufacturers will add formaldehyde in the granulation process, thus forming a thin urea-formaldehyde layer on the surface of the urea particles, which is not allowed in the industrial urea.
According to China’s relevant standards, industrial urea in addition to iron content, alkalinity, sulfate, water intolerance and other requirements, the rest of the main quality indicators, such as nitrogen, diureas, water content and other major quality indicators are not very different, the general large and medium-sized enterprises of the urea products are able to meet the quality requirements of industrial urea.
