Dear forum members, let’s discuss the following: How many colors are there for urea products? What are the ways to add colorants?
According to the quality standard GB 2440-2001 for urea, its color should be mainly white or light in color, with no other colors allowed. Otherwise, it does not meet the **standards and is therefore an unqualified urea product. Therefore, it is recommended not to add any colorants to urea.
No other colorants need to be added to urea; if the produced urea has a color, it is considered an inferior product. It might be corrosion of the high-voltage equipment. The system contains oil, etc. However, the specific color needs to be analyzed on a case-by-case basis.
Urea products should be white. If red or something else appears. That is substandard product. Moreover, it causes severe damage to the production equipment, indicating serious corrosion of the equipment.
