Description
Product description:
Urea (Urea), also known as urea, carbamide, chemical formula is CH4N2O or CO(NH2)2 [8], is an organic compound composed of carbon, nitrogen, oxygen and hydrogen, is a kind of white crystal. One of the simplest organic compounds, it is the main nitrogenous end product of protein metabolic breakdown in mammals and some fish.
As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to preserve, easy to use, small damage to the soil, is a large use of a chemical nitrogen fertilizer, is also the highest nitrogen content. Urea is synthesized from ammonia gas and carbon dioxide under certain conditions in industry.

Application:
Urea is a kind of high concentration nitrogen fertilizer, is a neutral quick fertilizer, can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, long-term application has no adverse effects. Livestock can be used as feed for ruminants. But in the granulation temperature is too high will produce a small amount of biuret, also known as biuret, has an inhibitory effect on crops. The content of urea urea for fertilizer should be less than 0.5%. When biurea content exceeds 1%, it cannot be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and urea content in other application periods should not be too much or too concentrated.
Industrial used:It can be used as a large number of melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, reduced brown BR, phthalein blue B, phthalein blue Bx, monosodium glutamate and other products of the production of raw materials. It has brightening effect on chemical polishing of steel and stainless steel, and is used as corrosion inhibitor in metal pickling. It is also used in preparation of palladium activation solution.
