A check: Check the production batch number and seal of the package. True urea bags are clearly sealed on the front and back sides of the machine, and the production batch number on the fake urea packaging is unclear or non-existent. Most of them are sealed by a single line.
Second look: True urea is a translucent and consistent colorless particle. If the surface of the particle is too bright or dark, or appears shiny, mixed with impurities.
Three reports: The urea produced by a regular manufacturer has no volatile odor under normal conditions, and only produces ammonia smell when exposed to moisture or high temperatures. If the volatile flavor is normal under normal conditions, it must contain impurities.
Four touch: true urea particles of the same size, not easy to agglomerate, strong fluidity, and thus feel better; and fake urea hand touch burning sensation and tingling feel.
Five burning: pure urea on the red charcoal quickly dissolve, take a white smoke, ammonia smell. If there is intense burning on the charcoal, a strong light, and a "click" sound, or melting, it must be mixed with impurities.
Six said: The urea standard weight produced by regular manufacturers generally differs from the actual weight by less than 1%. However, the true weight of urea is different from the standard weight.
