Property:It is soluble in water and alcohol. Its water solubility is faintly alkaline. It decomposes when heated over fusing point. Under high temperature, it can undergo a condensation reaction and form biuret, triuret and polyhydrocyanic acid.
Uses
Urea is a high concentration of nitrogen fertilizer, is a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer. In industry, for steel, stainless steel chemical polishing has whitening effect, used as a corrosion inhibitor in the metal pickling, also used in the preparation of the palladium activation fluid..
Packing and Transport
50kg ,500kg,1000kg PP bag or pallet available ,Stored in cool, dry and draughty storehouse. Kept away form fire, heat source, moisture. Avoid packing damage. when necessary should be placing the waterproof canvas.
Executive Standard:GB/T 2440-2017
