A paper document from the Ministry of Industry and Information Technology, the country is finally settled dust. This policy encouragement is undoubtedly a boon to the domestic automotive urea market. Car urea has become a hot vocabulary. As the market opportunities and development opportunities that all the business people look forward to are on the verge of looming, the mystery of car urea is unveiled. What kind of market prospects does domestic car urea face in the future? Market development? The China Truck Network reporter recently interviewed Tao Jiaming, chief technical expert of the Dean of Technology and Economics Research Institute of Sichuan Meifengjia Blue Environmental Protection Technology Co., Ltd., to further understand the development of domestic vehicle urea. In 2015, the explosive consumption of heavy trucks will be the key The establishment of a new industry and a newly developed product in the market must have its decisive factors. In 2014, China’s overall macro economy maintained its growth momentum, and its target for China’s GDP was expected to increase by around 7.5%. The implementation of the national IV emission standard policy has further landed, and sales of the four vehicles using SCR technology are expected to grow steadily. President Tao Jiaming pointed out: On the one hand, with the increasing calls for environmental governance, the country’s emphasis on environmental governance has increased. The scope and intensity of the implementation of the State Fourth has increased irreversible; on the other hand, the rapid development of the logistics industry, "demand" for trucks The increase in potential demand for dump trucks and special-purpose vehicles has driven the sales of national four-vehicle vehicles to continue to increase. The sales volume of vehicle urea increased gradually in recent years. In 2011, the market sales volume was approximately 11,000 tons; in 2012, the market sales volume was approximately 15,000 tons; in 2013, the market sales volume was approximately 20,000 tons, and Dean Tao Jiaming analyzed: Based on The National IV emission standard is gradually expanding and implementation is expected. It is expected that the China AdBlue market will enter the initial stage of the start-up in 2014 and the annual sales volume will reach 50-80,000 tons. With the full implementation of the Fourth National Emission Standard, it is expected that it will usher in explosive growth in 2015. Analysis of the consumer groups of products helps their accurate delivery in the market. President Tao said: “In the future, the development of the market will be the largest consumer group in terms of market share.†According to data analysis, at this stage, heavy trucks account for 40% of the market share. In the relatively mature stage, heavy trucks will occupy the market share of vehicle urea. 50%. For the automotive urea market, heavy truck consumption will become a key issue that needs to be seriously considered. The quality of car urea is no small matter to be strictly controlled As a urea solution with a concentration of 32.5%, vehicle urea seems to be simple to produce, so it has attracted many manufacturers to try their best, making the car urea products on the market mixed, small workshops around the production is not difficult to find . So, is the production of urea for vehicles just a certain proportion of aqueous solution? of course not. President Tao said: “The quality of car urea is very important, so we must strictly control the quality of AdBlue. During the entire production process of the product, quality control is not just a slogan!†as a heavy-duty diesel vehicle to achieve the national four or more emission standards The essential consumables, the quality of car urea is crucial. Inferior vehicle urea will not only affect the exhaust emissions of motor vehicles, but also cause harm to the SCR system. Studies have shown that 1 gram of salt is enough to contaminate a ton of AdBlue! From several perspectives, the accumulation of insolubles in urea for vehicles may block the infusion lines and nozzles of the SCR system, and it can also block the pores of the catalyst, affecting the catalytic effect, and in severe cases can damage the engine. Impurities, phosphates, and metal ions (sodium, magnesium, potassium, calcium, iron, zinc, chromium, copper, nickel, and aluminum) in AdBlue affect the activity of the SCR catalyst, which in turn affects the catalytic reduction efficiency. In general, the impact of urea on poor quality vehicles is manifested in: catalyst poisoning; clogging of pipelines and nozzles; damage to SCR systems; affecting the normal operation of vehicles; increasing equipment maintenance costs and increasing vehicle operating costs. The high-quality AdBlue can extend the service life of SCR systems, reduce maintenance costs, improve operational capabilities, and save operating costs. Therefore, the production control and rigorous quality inspection of all parts of the vehicle urea are indispensable. Car urea brand road has just begun The Ministry of Industry and Information Technology of the People's Republic of China announced on the 27th of December 2014 that “the “announcement†applicable to the third phase of the national automobile emission standard diesel vehicle product “announcement†will be abolished on December 31, 2014, and the national diesel vehicle product will not be available for sale on January 1, 2015 . The implementation of the National IV will undoubtedly be beneficial to the domestic automotive urea market. Vehicle urea, which is closely related to the fourth national emission standard for heavy-duty diesel engines, is also considered to be a good thing. However, opportunities have always been accompanied by numerous obstacles at any time. The development of car urea in the domestic market is still not clear. In other words, the road to brand building of automotive urea has only just begun. Regarding the brand development of automotive urea, President Tao said: “Sichuan Meifeng adheres to the goal of improving product quality and building a well-known brand, providing safe and reliable products to the market, and at the same time adopting the market strategy for China’s AdBlue. Feng Jialan, in its own right, has plans in the following five areas: the adoption of the marketing model of 'direct sales + distribution + retail chain + exports'; the establishment of a scientific logistics hub and regional warehouse, cooperation with high quality logistics providers; emphasis on heavy trucks The market, as well as customer and engineering vehicles, cooperate with domestic automakers to provide after-sales services, set up compounding stations in key regions, shorten transportation distances and improve product competitiveness; strengthen retail market management and build reliable shopping channels.†China has a vast territory, a complex climate, and severely uneven regional economic development; the market is confusing, counterfeit goods are easy to breed, and brand management is difficult; and AdBlue is a liquid product, which has high logistics transportation costs and is limited; as an exhaust gas treatment product, AdBlue is subject to National policies have a great influence. The influence of many factors makes it not easy to promote vehicle urea in the domestic market. In any case, there is still a long way to go for the construction of a car urea brand in China. However, the objective demand for the automotive urea market continues to increase. At the same time, the consumer’s subjective awareness of the product continues to increase. With the growth of the sales volume of the national four-vehicle vehicle, the vehicle urea channel will expand faster and faster. In China, brand building will inevitably be the key to the long-term development of vehicle urea in China.

10L Specifications Urea Products for Vehicle 
SCR post-processing technology
(1) Excellent transparency The biggest advantage of organotin stabilizers is that they have excellent transparency. The use of organotin stabilizers in PVC formulations can produce crystalline products. Because of this, organic tin can be used in bottles, containers, corrugated boards, various types of rigid packaging containers, hoses, profiles, films, etc.
(2) Extraordinary thermal stability In terms of thermal stability, there is no other type of thermal stabilizer that can surpass it. Therefore, it is the preferred stabilizer for rigid PVC, and some varieties have better performance in soft products. Suitable for all PVC homopolymers, such as emulsion, suspension and bulk PVC, as well as vinyl chloride copolymers, graft polymers and polymer blends.
(3) The product is non-toxic. Most organotin stabilizers are non-toxic, and the migration of organotin stabilizers in rigid PVC is minimal. Therefore, organotin stabilizers are the preferred heat stabilizers for PVC for food contact.
(4) Good compatibility. Organotin stabilizers have good compatibility with PVC, so there is generally no precipitation on the metal surface, such as lead salt stabilizers and metal soap stabilizer systems.
(5) Poor lubricity Sulfur-containing tin stabilizers have poor self-lubricity. Therefore, many commercially available sulfur-containing organotins are equipped with lubricants to prevent hot melt from adhering to processing equipment during processing.
(6) High cost Compared with other types of stabilizers, the overall performance of organotin stabilizers is closer to the ideal stabilizer. However, all organotin stabilizers, regardless of their structure, have the main disadvantage that their manufacturing cost is much higher than that of lead stabilizers or metal soap compounds. In recent years, by adopting new synthetic technology, or reducing its usage in formulas, its formula cost has been reduced. In the 1970s, foreign countries developed low-priced tin products, which reduced the tin content, which also reduced the price to a certain extent.
1.2 Lead salt
(1) l Excellent stability experiments proved that among the commonly used basic lead salts, the heat resistance of sulfite is better than that of sulfate, and the heat resistance of sulfate is better than that of phosphite. The tribasic lead sulfate, which is widely used in the PVC industry, has a higher effective lead content and shows better thermal stability than other products.
(2) Excellent insulation. Because lead salt is non-ionic and non-conductive, it is inert, which makes lead salt stabilizers widely used in wire and cable industries.
(3) Excellent weather resistance. Many salt compounds can act as white pigments and can show strong covering power, so they have strong weather resistance.
(4) Poor transparency Transparency is a problem related to weather resistance. When used in wires, cables and record materials, there is no need to care about transparency, because most of these products are white or very dark black.
(5) Inexpensive lead salt stabilizer is the lowest price among all stabilizers. Therefore, despite the continuous introduction of new stabilizers, lead salt stabilizers still dominate the stabilizer market after half a century. The composite lead salt introduced to solve the dust and dispersion problem has increased in price, but still maintains a competitive advantage with other types of stabilizers.
(6) The toxicity of the toxic lead salt stabilizer limits its application in many occasions with strict hygiene requirements. For example, many countries have revised the lead content standards in drinking water, and it is no longer possible to use lead salt in PVC water pipes.
(7) Poor dispersibility The dispersibility of salt lead is poor, but the newly launched one-package product is equipped with lubricants, which solves the dispersibility problem to a certain extent. Because of the above characteristics of lead salt stabilizers, they are especially suitable for high-temperature processing. They are widely used in various opaque hard and soft products and cable materials, such as various pipes, plates, indoor and outdoor profiles, foam plastics, artificial leather, and wires. Cables, records, welding rods, etc. The most important lead salt stabilizers are tribasic lead sulfate, dibasic lead phosphite, and dibasic lead stearate.
1.3 Organic antimony
(1) Better stability. The organic antimony stabilizer has basically the same color stability and lower melt viscosity as organotin at the same temperature. In the twin-screw extrusion process, the effect is particularly outstanding when used in combination with calcium stearate. .
(2) The price of organic antimony stabilizer is much lower than that of methyl tin or butyl tin. In addition, the amount of organic antimony used is relatively low, so the use of organic antimony can achieve a better performance/price balance.
(3) The product is non-toxic. In the United States, when a twin-screw extruder is used to manufacture PVC pipes, the PVC water supply pipe manufactured with a formula composed of antimony stabilizers, calcium stearate and other lubricants conforms to the U.S. NSF (National Sanitation Foundation) )Regulation.
(4) Poor transparency and light stability. The transparency of organic antimony compounds is not as good as organotin stabilizers, and it is also lower than the barium/fu and calcium/zinc metal soap system. It is close to lead salts and has poor light stability, so antimony is stable. The agent is mostly used for indoor products without color requirements. The antimony stabilizer itself is also required to be stored in an opaque container.
(5) Poor lubricity. Antimony stabilizers have poor lubricity. Therefore, its use must be combined with a large amount of lubricant without exception.
1.4 Metal soap
(1) The tin soap stabilizer Fu soap is the best type of metal soap. Its advantages are also reflected in the absence of initial coloring, and can produce colorless and transparent products; excellent light stability; it has the effect of preventing precipitation and adhesion. . However, because tin salt is toxic, there are strict regulations on its manufacture and use in the Labor Safety and Health Law. In recent years, the use of Fuzao has shown a downward trend.
(2) Zinc soap stabilizerThe thermal stability of zinc-based stabilizer to PVC is extremely poor. The sample with zinc soap suddenly turns black when heated, that is, the so-called "Zine burning" phenomenon occurs, but it has the following advantages: The initial coloring is excellent; the effect of preventing fouling is good; it can improve the weather resistance; many zinc soaps are recognized as non-toxic stabilizers, so they can be used in non-toxic formulations with calcium soaps.
(3) Barium soap stabilizer Barium compounds have good thermal stability and good lubricity, but the red initial coloration occurs during processing, and it is easy to cause sticking to the roller.
(4) The stability of calcium soap stabilizer is poor, but it is recognized as a non-toxic additive in the world and has excellent lubricity.
(5) Other metal soap stabilizers used in the industry include magnesium stearate, file stearate, aluminum stearate, potassium stearate, etc., among which magnesium stearate is similar to calcium stearate and can be used Materials that are in contact with food; aluminum stearate is similar to zinc stearate, and is approved by the U.S. FDA and the Japanese Vinyl Chloride Food Hygiene Association for food packaging; Stearic Acid files and potassium stearate are also non-toxic products and belong to lead salts , Tin soap and barium soap substitute.
(6) The performance requirements of the composite metal soap stabilizer processing industry for stabilizers are various, and a single metal soap often cannot meet the use requirements, so the use of composite stabilizers has become a trend. A single metal soap compound is rarely used in the PVC industry, and it is usually a compound of several metal soaps. This compound is not a simple addition of properties, but takes advantage of the synergy between the components. The composite metal soap stabilizer generally includes the stabilizer main body (i.e. metal soap), solvent (organic solvent, plasticizer, liquid non-metal stabilizer, etc.), functional additives (auxiliary stabilizer, transparency modifier, light stabilizer, Lubricants, etc.). According to the form, it is divided into solid compound and liquid compound. According to the main component, it can be divided into calcium/zinc compound stabilizer, barium/fu compound stabilizer, barium/zinc compound stabilizer, etc. Among them, the calcium/zinc composite stabilizer has a pivotal role in replacing toxic metals because it is non-toxic.
1.5 Rare earth stabilizer
(1) Excellent thermal stability The thermal stability of rare earth stabilizers is better than traditional lead salt series and barium/zinc, barium/ho/zinc stabilizers. In some applications, rare earth stabilizers can partially or completely replace organotin.
(2) Good transparency. The refractive index of rare earth stabilizers is very close to that of PVC Resin, which can replace traditional organotin and be used in the field of products with higher transparency requirements.
(3) Excellent weather resistance. Rare earth elements can absorb 230-320nm ultraviolet light. Therefore, rare earth stabilizers have anti-photoaging effects and are suitable for outdoor products such as PVC corrugated boards and window materials.
(4) Excellent electrical insulation properties. Some rare earth multifunctional stabilizers can be used to replace lead salt stabilizers in cable material formulations, and their electrical insulation properties are comparable to lead salts.
(5) Non-toxic, safe and hygienic. Rare earth elements are low-toxic elements and have no toxic hazards to the human body in their production, processing, transportation and storage. Rare earth stabilizers are non-toxic products and can be used in food packaging and medical packaging products.
(6) The processing performance is slightly worse. In the case of a large amount of rare earth stabilizer, the roll release of the material is not ideal, and there is a tendency to press out. Generally, better results can be achieved by using stearic acid or calcium stearate in combination.
In summary, rare earth stabilizers can be used for water pipes, injection pipe fittings, window frame profiles, door panels, wire ducts, foam products, artificial leather, cable materials, soft and hard transparent products, food packaging materials, etc.
1.6 Auxiliary stabilizers Auxiliary stabilizers include phosphite, epoxy soybean oil, hindered phenols, etc., which mainly rely on the synergistic effect between metal stabilizers to improve the stabilizing effect, and are generally called co-stabilizers. In addition to compounds such as mesaminocrotonic acid ester, 2-phenyl saccharin, vein derivatives, and diketone can be used in combination with metal stabilizers to improve the effect of metal stabilizers, they also have a certain stabilizing effect. Such compounds are usually called pure organic stabilizers. With the development of PVC stabilizers today, the progress of metal stabilizers is relatively slow, and the research and development of auxiliary stabilizers are unprecedentedly active, which has constituted a major trend in the field of PvC stabilizers. Auxiliary stabilizers are rarely used alone, and are often used in conjunction with primary stabilizers to improve initial coloration or improve long-term stability.
