High quality urea solution: not so simple because of China's national road emissions of four main stream technology selected SCR, and therefore must use car exhaust with urea commodities for nitrogen oxides for processing. That is, if heavy-duty trucks and buses to reach the national IV emission norms, must be filled with cars with urea solution. Mentioned here, many people may think that what's difficult, is not that is bought urea, and then put it in accordance with the share 32.5:100 melt in the water, and added to the car it? Far from reality, the car with a high demand for urea, the norms of strict, far more than all fantasy. Blue, general manager of the Department of Technical Director Huangdong Wei told reporters, on the one hand, the SCR system, urea nozzle is very small, if not high enough purity urea solution, or spray does not come out, or can not spray form; on the other hand, post-processing binary catalyst into a honeycomb, mouth very small, if urea solution inside impurities, simply put obstruction. "This is to make very pure water purification situation, peeling during all impurities, leaving only pure water; urea also very pure urea urea solution is a very delicate thing, whether it is production, storage, transport and distribution, plus Notes and many other aspects to be higher norms, strict requirements, in order to have a qualified real goods. "Wang Baofeng said. In this regard, Liaoning Rady approach is: first and foremost, plan to produce a reasonable layout, in strict accordance with norms to complete the construction of clean production areas and equipment areas, while repairing advanced production equipment and make everything all available targets control. Second, on the supply chain management, material suppliers should be implemented on the evaluation criteria will be included in the list of qualified suppliers, the acquisition of all materials must be qualified suppliers. Full implementation of all the material comes into play when the factory inspection, strict quality control from the source to eliminate substandard goods into the plant. Thirdly, the production process, the inspection part tracking, quality inspection of goods in real time, to avoid substandard goods into the next process. Goods to be inspected before leaving the factory and then, checks at each level to ensure that goods shipped to the pass rate. Eventually, commodity storage, with regard to the urea solution merchandise must be sealed, shading, dust, pollution and other characteristics of materials, containers and storage areas delineated from scratch commodities alone isolation, adopt dust-free handling, hanging thermometer and humidity meter to monitor the environmental situation in a timely manner and promptly adopt ways to improve. "In addition, there is little core technology, transmission and distribution system that is because the transport process in doubt, urea solution also involves a raise questions. If the vessel failed to get raises, there is no doubt that commodities will be contaminated, So how to choose fit standard containers, to avoid secondary pollution is particularly important. "Zou Jianbo said. Huge shopping malls and more self-discipline required to follow the norms and the implementation process of the four countries continue to promote, market demand for automotive urea solution will also continue to release. Insiders speculate that the next few years, the automotive urea mall will experience a process of development and growth. To sell 700,000 heavy goods vehicles per year, each country consumes four specification vehicle heavy truck 2 tons of urea per year accounting, only heavy trucks market, the demand for new vehicles urea solution to reach the 1.4 million tons.
