Ningde vehicle urea developed background and use what is Ningde vehicle urea solution (AdBlue) Car urea solution (AdBlue) with removal of metal ions, out of stock, desulfurization, high-purity urea, biuret and electronic ultrapure water together preparation of the solution, the solution of urea content of 32.5% (mass fraction). Most heavy-duty diesel engine manufacturers at home and abroad using the SCR (Selective Catalytic Reduction) technology to meet the country Ⅳ and Ⅴ country vehicle emission standards. Select SCR technology vehicles must add urea solution as catalytic reducing agent. Xuancheng urea car works: How it works is the application of SCR technology (selective catalytic reduction), SCR technology is in the heat of the exhaust gas for cars car used to add urea solution (AdBlue called commodity), the urea solution SCR catalyst in the subsequent reaction with the nitrogen oxides, it is converted to nitrogen and water vapor. Urea solution through a heated tube drawn from the urea solution tank, and then through the compressed air, so that it is evenly sprayed into the exhaust gas gasification (about 180 ℃ decomposition), and the release of ammonia, nitrogen and manipulation in the SCR catalyst converted into nitrogen oxides and water vapor acceleration harmless, while absorbing the harmful soot particles. After using the car urea solution, why the car fuel it? This is a colleague of marketing communication with customers in the process, often asked questions. As we all know, compared to gasoline engines, diesel engine thermal efficiency higher than 30% of greenhouse emissions 45% lower than gasoline, so more and more into the public eye diesel vehicles will be the trend. However, the harmful emissions of diesel particulate matter is too large, which requires stringent emissions regulations for diesel engine vehicles with urea solution with urea car Specifications: Product Specifications content 31.8-33.2% chloride, ㎎ / kg ≤0.2 Density , ﹝ 20 ℃) ??g / ml 1.087-1.092 aldehydes, ㎎ / kg ≤5 refractive index, ﹝ 20 ℃) ??1.3814-1.3843 potassium, sodium, calcium, magnesium, iron, aluminum, ㎎ / kg ≤0.5 biuret, % ≤0.3 zinc, nickel, chromium, copper, ㎎ / kg ≤0.2 alkalinity (NH3 dollars),% ≤0.2 not matter, ㎎ / kg ≤20 phosphate, ㎎ / kg ≤0.5 crystallization temperature of -11.0 ℃ Dongguan Wing Tai Ming City Environmental Protection Technology Co., Ltd. R & D, production, sales for the integration, commitment and control of atmospheric pollution emissions of nitrogen oxides. The company has a full-leading automated production, bottling equipment and testing equipment. The company's main "Blue Su Jia" brand car with urea solution, denitrification solution of sodium silicate solution automobile and other environmental chemicals. Product is suitable for SCR systems for the country's four major emitters handling diesel exhaust. The company of "faith based, innovation Zhiyuan; customer first, reputation first" purpose, adhere to "go beyond the self, the pursuit of perfection, harmony with nature and development" in the camp philosophy. Class quality to meet customer needs! The best return on social services! Because of national environmental protection department to further reduce diesel emissions of nitrogen oxide pollutants discharge. Domestic commonly known as Euro IV standards. Engine manufacturers began using SCR technology (Selective Catalytic Reduction Technology selective catalytic reduction) to meet the requirements of environmental protection department. Diesel Exhaust Fluid (domestic commonly known as: automotive urea, urea vehicle, automotive environmental urea), is necessary to use SCR technology consumables. SCR systems including urea tank (diesel exhaust treatment fluid loading), SCR catalytic reaction tank. SCR system is running: When the discovery of nitrogen oxides in the exhaust pipe, the urea tank is automatically ejected diesel exhaust treatment fluid, diesel exhaust treatment fluid and nitrogen oxide redox reactions SCR catalytic reaction tank, generate no nitrogen and water vapor exhaust pollution. If you do not load the diesel exhaust treatment fluid, or pure enough, or inferior quality will occur automatically slow the vehicle engine. Meanwhile, shoddy quality diesel exhaust treatment fluid can contaminate the SCR catalyst in the catalytic reaction tank, resulting in serious consequences. (Recent market industrial urea blending counterfeit products, shoddy! Please consider carefully when asked to buy, look for the trademark!) Car urea temperature requirements are more stringent, in the following -11 ℃ crystallization occurs. This issue aroused concern truckers. Truckers perennial running around the north and south, the northern regions may make the car very cold crystallization of urea, a phenomenon of truck drivers transport stroke causing distress. Total Ng explained: "Small car packed with urea solution can be stored indoors to avoid low temperature crystallization, and in automotive assembly of SCR systems, storage truck with insulation function with urea solution storage tank, while the system is equipped with a heating device can prevent crystallization of the product at low temperatures, in order to ensure the normal operation of the system.
