First, look at the color of colorless transparent, will not appear yellow, white, cloudy situation. The production and purification of urea used in the previous three-stage crystallization of urea as raw materials, the process is now generally used after upgrading the resin crystallization method, the purity of more pure. The raw materials used for normal automotive urea should be industrial grade urea, not agricultural grade urea. Often because the raw materials used are different. Its composition contains metal ions or other impurities, there will be yellow or other color and turbidity phenomenon.
It is these metal ions or impurities that can seriously affect the normal operation and service life of the SCR system. Second, look at the barrel wall authentic car urea crystallization point in the -5℃~-11℃, and most of China and the season will not reach this temperature. The Chinese orchid Yue Chi car with urea has not been a case of crystallization during the use of the phenomenon. As for the winter in the north, it is necessary to add an anti-crystallization agent in the vehicle urea. If you open the lid and find that the wall is attached to the crystal that is crystallization, this product if used in a low temperature environment will be a large amount of crystallization or complete crystallization, simply can not be used. Factors affecting the crystallization point of urea in addition to the influence of impurities, the most important point is not strictly according to 32.5% of high-purity urea and 67.5% deionized water proportion production. And this proportion of the production of automotive urea is to deal with the best ratio of exhaust gas. AdBlue crystallization is normal in the case of crystallization and 零下5度 after splashing and evaporation of droplets. But barrels are usually not easy to crystallize. Therefore, the crystallization point is usually not reached to crystallize the basic can be judged as unqualified products.
Or that pain point: impurity content is not standard, the proportion of substandard will seriously affect the normal use of SCR system. Third, audit qualification to buy chemical products must audit each other's production qualification and business license. Regular manufacturers to meet the state Ⅳ state Ⅴ standard of automotive urea, will be accepted by the State administration of quality Supervision, inspection and quarantine quality checks and inspection. The qualified report of the inspection has greatly filtered out the unqualified urea.
There are currently two patents for the orchid Yue Chi car urea. Iv. View enterprise quality standards and factory inspection report Shandong New Blue Environmental Protection Technology Co., Ltd. is a high-tech enterprises, mainly engaged in heavy truck tail gas control SCR car urea solution, as well as automotive urea solution intelligent Manufacturing machine production and research and development, the headquarters is located in the beautiful World Kite Capital and commercial vehicle accessories base in China-Weifang, The area has Weichai Power Group, Beiqi Foton, Shengrui transmission, Fuyuan turbocharger, conclusion technology, Parker Filter and many other world-renowned commercial vehicle supporting enterprises. Its holding company for more than 9 years has been focused on automotive urea raw materials research and development production and export, products are exported to more than 20 countries and regions worldwide, accumulated up to more than 200,000 tons, by the foreign hundreds of adblue production enterprises preferred. (AdBlue is a VDA-certified brand of the German Automobile Industry Association). The company passed the ISO9001 Quality system certification, the company to the perfect result through the car with urea solution AdBlue the world's most stringent German enterprise industry Association VDA Certification, the company has a professional laboratory of automotive urea, products to do every batch must be checked and meet the EU ISO22241 standards, the company leading products '
Jin Pure ' brand car with urea solution of the indicators are superior to national standards. The company's global first small-scale automotive urea solution intelligent Manufacturing integrated machine, to solve the current automotive urea solution supply chain, high logistics costs, packaging waste and two pollution problems. Using cloud technology to monitor the production process and quality in real time, mobile phones can be easily queried. All-in-one machine will be ordinary tap water through more than 10 layers of precision filtration purification to achieve electronic standards and continuous monitoring, the use of imported German urea quality sensor (Urea quality sensor) detection data more authoritative----more accurate, automatic calculation of the software ratio, automatic adjustment of concentration, the entire production process to achieve automation, Fool one-click operation. Small footprint, high efficiency, strict quality assurance, customers can use the car urea in the place to complete the production of the site easily. At the same time for the customer greatly reduced costs. is the current domestic through the Ministry of Industry and China Internal Combustion Engine Industrial Association approved the authoritative car urea solution manufacturing machine equipment.
