The post-processor market in 2013 moved around with diesel engine emission upgrades. According to the plan, as of July 1, 2013, diesel vehicles will implement the fourth national emission standard, which will provide opportunities for companies with long-term storage and post-processing facilities. The "Opinions of the General Office of the State Council on Strengthening Energy-saving and Emission Reduction of the Internal-combustion Engine Industry" pointed out that in the field of exhaust after-treatment devices, the focus will be on selective catalytic converters, particulate traps, exhaust gas recirculation systems, three-way catalytic and catalytic converters. The technical level of the on-line diagnostic system and key gas sensors enhances the coordination and coordination between the exhaust aftertreatment device and the complete machine. This provision laid the foundation for the future development of the internal combustion engine reprocessing industry. In the past year, SCR was undoubtedly the most frequently used vocabulary in the field of automotive aftertreatment systems. This year was also a critical year for the emission standards of the automobile emission aftertreatment system products to the National IV emission standard and even the country's five emission standards. The pollutants emitted by automobiles mainly consist of particulate matter (PM) and nitrogen oxides (NOx). Although diesel vehicles account for a small amount of car ownership, PM and NOx emissions account for more than 70% of the total vehicle emissions. Diesel vehicles, especially heavy-duty diesel vehicles, are bound to become the focus areas for monitoring emissions reductions. Although the implementation of the country's four emission standards push and push again, but the mainstream diesel engine, post-processing system manufacturers have been stepping up research and development of the country's four products, always ready to market. At present, SCR is the main technical direction for domestic diesel engine emission upgrades. It is understood that the market size of diesel exhaust gas treatment each year is about 14 billion yuan, of which the market size of SCR exhaust gas treatment system is about 9 billion yuan. In China, SCR is an effective technology route for tail gas aftertreatment in the medium- and heavy-duty trucks field. The application of SCR system in the Chinese market has ushered in a rapid improvement phase. As the main force of the internal combustion engine industry, Weichai is the company that started the research and development of the National IV engine platform earlier in the country . In 2013, the post-processing system independently developed by Weichai has been applied in small batches in passenger vehicles and other fields. Weichai uses the self-developed post-processing control system and urea injection system to match the post-processing system with the entire vehicle. In addition, Shaanxi Auto also successfully completed the development and optimization of the National IV post-processing system in July 2013. It mainly carried out the optimization of the National IV urea injection system, the flow field analysis and optimization of the fluid system, and the optimized design of exhaust pipe optimization. Four post-processing system optimization, development of new SCR box brackets and other five aspects. EGR technology is a post-processing technology that can meet the national IV emission standards and is widely used in domestic light diesel engines. On November 5, 2013, the successful offline production of the 100,000th emission treatment product produced by Cummins in China showed that the SCR and EGR technologies that Cummins has applied in the market in Europe and North America have stimulated a huge demand in the Chinese market. With the rapid expansion of the scope of implementation of the National IV emission standard and the rapid expansion of the region in 2014, Yinlun shares expects that the market for EGR and SCR products for vehicle exhaust gas treatment systems will continue to grow substantially. In 2014, Yinlun shares EGR and SCR product sales revenue. It can increase about 90% and 350% respectively compared to 2013. The wide application of SCR technology is inseparable from the adequate supply of urea for vehicles. It is understood that consumption of urea solution for vehicles in the European market has maintained an average annual growth rate of 19% for three years. At present, the domestic market demand for automotive urea solution is about 10,000 tons. Several companies such as Jiangsu Kelansu Automotive Environmental Protection Technology Co., Ltd. and Sichuan Meifeng Chemical Co., Ltd. took this opportunity to pave the way for the expansion of vehicle urea capacity. On July 1, 2013, the national standard for automotive urea solutions was formally implemented. This standard is slightly higher than the local standards for vehicle urea solution products in Beijing and Shenzhen before, and the technical specification for automotive urea solutions (SAE-China J2901-2013) published by the Chinese Society of Automotive Engineers. . On the other hand, the national standards have also increased the regulations for vehicle urea filling devices, and put forward corresponding standards for filling containers, filling flow rates, filling spaces, etc. Consumers will be following the strict implementation of national standards by production enterprises. Beneficiaries. However, the new costs incurred by consumers for vehicle urea solutions are yet to be further verified by the market. It is understood that car urea solution will produce crystallization below -11 °C, so the vehicle urea solution storage tank and the injection line needs insulation and heating functions. It is worth noting that Liaoning Rundi independently developed a urea solution for low temperature commercial diesel vehicles with a devitrification temperature of less than -25°C and -35°C. This technology solves the problem of startup of commercial vehicles in cold and cold regions. It has been approved by a number of engine plants and vehicle manufacturers.
Reagent Bottle sizes include 100 ml, 250 ml, 500 ml, 1000 ml (1 liter) and 2000 ml (2 liter). Older bottles, especially for medical use and for expensive chemicals, can be found of capacities well under 100 ml. The selection of caps and stoppers that Reagent Bottles are closed with are as important as the material the bottles are made of, and the decision as to which cap to use is dependent on the material stored in the container, and the amount of heat which the cap can be subject to.
