All type of urea are available- Urea Industrial grade Urea Agricultural Urea Urea also known as carbamide is the worlds most common nitrogen fertilizer and has been used uniformly in all the agricultural lands of the world. Urea can be produced as prills, granules, flakes, pellets, crystals, and solutions. Urea is a nitrogenous compound containing a carbonyl group attached to two amine groups with osmotic diuretic activity. It is widely used in fertilizers and is an important raw material for the chemical industry.

Agricultural urea N46 46% Properties of urea Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 â?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present. Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �³ï¼? The melting point is 132.7 â??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 â?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 â??ï½? 160 â?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 â??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption. Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces. The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made. New standard GB/T2440-2017

UREA H2N-CO-NH2 GOST 2081-2010 (HS code 310 210 1000) Urea is intended for use in the industry as a raw material in the manufacturing of glues, resins and others, in agriculture, including smallholdings and farms as a mineral nitrogen fertilizer, and also in livestock as feed additive. Urea is produced in two grades depending on the purpose.

Crystal carbamide (urea) is received from ammonia and carbon dioxide. carbamide is used in an industry as raw materials at manufacturing of pitches, glues, etc., for use in agriculture as mineral nitrogen fertilizer. Carbamide can be utilized in animal husbandry as fodder additive. Depending on purpose, two carbamide marks are produced: A- for industry; B for agriculture. Carbamide is non-combustible, fire-and is explosion-proof under normal conditions. As regards to its influence on organism, it falls into 3-rd class of hazardous substances. Carbamide is packed in paper bitumized of laminated bags, polyethylene bags, woven polymeric laminated bags woven polymeric bags with inserts, and also in soft specialized containers as MKR-1, OS. Carbamide is stored in closed store rooms protecting the product from rainfall. At storage of product in bulk its mixture with other fertilizers is not permitted. It is permitted to store carbamide containers and transport packages fastened by synthetic film on open areas. Warranty period of product storage 2 years from the date of manufacturing.
