UREA

Urea is a neutral quick-acting fertilizer with a chemical formula of CO(NH2)2 and a nitrogen content of up to 46%. ‌‌Urea is a white crystal that is tasteless and odorless, easily soluble in water, ethanol and benzene, and slightly soluble in ether and chloroform. The nitrogen content of urea is the highest among solid nitrogen fertilizers, which makes it a highly efficient nitrogen fertilizer. After application, no harmful substances will remain in the soil, and it has little destructive effect on the soil, so it is widely used. The application methods of urea include as a base fertilizer or topdressing. Urea is decomposed into ammonium carbonate by microbial action in the soil, and ammonium carbonate is easily absorbed by plants, so urea has a rapid fertilizer effect. However, the utilization rate of urea is low, about only 20%-30%, and most of the urea applied to the soil will be lost or volatilized with water. In order to improve the utilization rate of urea, it can be carried out by deep application in advance or foliar spraying. The method of foliar spraying of urea is simple and effective, which can make urea quickly enter the leaves and participate in various metabolic processes of crops, significantly improving the utilization rate of urea.

Product Description

WHAT IS DIESEL EXHAUST FLUID (DEF)

Diesel Exhaust Fluid (DEF) is a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized

water for specific use in Selective Catalytic Reduction (SCR) systems. Using this fluid in diesel-powered vehicles, such as

trucks, buses, and tractors, helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%. It is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle.

How Diesel Exhaust Fluid Works

When injected into the exhaust stream with a specialized dosing module, DEF vaporizes, leaving amonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor-making for cleaner emissions. Making sure you do not run out of DEF in an SCR equipped truck is simple - watch the DEF gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23 gallons depending on the truck's application.

Automotive Grade Urea

Automotive Grade Urea is a special, uncoated version of highest purity. It is a main component of urea solutions like Diesel Exhaust Fluid or AUS40/45 which are used within SCR-systems for the reason of NOx reduction. It is the only type of Urea that meets the ISO 22241 specification and the only suitable Urea for the production of DEF/AUS32/ARLA32 solutions. For meeting the ISO 22241 the Urea needs to be of highest purity/quality.
