The reporter was informed on March 12, 2012 that the goal-oriented project of the National 863 Program, which was undertaken by Beijing University of Chemical Technology and other units, has been adopted for the large-scale production of nano-elastomer composite materials for high-performance tires, and a new type of fuel economy has been developed. Safety tires. Assembled with this new type of nano-tire , the fuel consumption of a car can be reduced by about 5% compared to the existing ordinary radial tires . At present, this kind of fuel-saving tire has entered the mass production stage and will soon be on the market. "Smart" tires: 4 million tons of fuel On March 12, 2012, the oil price rise window opened again, and the rising oil prices have caused car owners to always worry. “Driving is convenient, but the oil price can't be sustained.†Mr. Dong, a citizen of Tiantongyuan who lives in Tiantongyuan, drives to work. The average daily fuel cost is about RMB 50. Hearing about 5% of fuel-efficient tires, he asks where to sell. . In addition to car styling, vehicle weight, and engine efficiency, tires are also one of the key aspects of vehicle fuel economy. When the vehicle is moving, the tires seem to be rolling, but the soft rubber tires are pressed and deformed with the road surface, and a large number of sliding frictions are formed inside. The increase in resistance also consumes more fuel. The tires developed by North Chemicals are "smart." “We have changed the internal structure of the tire tread rubber material, and the intermolecular sliding force can be large when braking and running small, so as to achieve the purpose of fuel saving,†said Wang Yiqing, a researcher at the State Key Laboratory of Organic Inorganic Composite Materials of Beibei Chemical Industry. According to reports, the fuel-saving mystery of the new tires lies in the use of solvent-polymerized styrene-butadiene rubber. The overall performance of this material is superior to other traditional tire raw materials. In addition, fuel-saving tires also have a secret weapon - white carbon black. Wang Yiqing said that in the past, the manufacture of tires required the addition of carbon black to the raw materials, which could help the rubber to resist ultraviolet rays and prevent the rubber from “aging†too quickly. However, there is a layer of scales on the surface of the carbon black, and the rubber is adsorbed on the scales. When the tire rolls, there is a slip between them and the frictional resistance increases. The structure of white carbon black and carbon black is different, the surface is smooth, and the rubber is chemically bonded. When the tire rolls, the frictional resistance can be minimized. After the actual estimation of the sports field, the new type of tires save 5% of the fuel consumption of the radial tires currently in use. According to the calculation of 80 million tons of gasoline consumed in China in 2011, the country can save 4 million tons of gasoline each year, saving 34.32 billion yuan in fuel expenses. At present, fuel-efficient tires have entered the mass production stage of the factory and are planned to have a capacity of producing one million sets per year. Wear-resistant tires: 10,000 tons of PM10 per year Wear in tires can generate dust, which may be one of the sources of PM10. According to reports, at present, the life of car tires in China is about 100,000 kilometers, and the thickness of driving wear is about 3 millimeters. It wears out from use to scrapping and generates about 1 kilogram of dust. Beibei Chemical is developing a wear-resistant tire that can extend its service life to 150,000 kilometers and reduce dust production by about 30%. According to this calculation, the city’s 5 million motor vehicles can reduce dust emissions by about 1,000 tons per year. Due to the possible addition of a small amount of auxiliary materials such as heavy metals during tire production, dust formed after abrasion will affect the health of urban residents. This reporter learned that North Chemical Tire technicians are working to develop new environmentally friendly tires to reduce the risk of tire dust, such as the use of environmentally friendly aromatic oils, naphthenic oils and natural vegetable oils extracted from orange peel, soybeans, etc., to reduce heavy metals such as zinc oxide use. Safety “retrofitting tiresâ€: promising to promote After completing the energy-saving tire project, the three units once again joined forces to initiate another project of the 863 Program, "Continuous dynamic desulfurization of waste rubber and the preparation of radial tire technology," to improve the use of waste rubber in tires and reduce rubber imports. At present, China has an annual output of 456 million automobile tires, which has a great demand for rubber. Wang Yiqing said that developed countries such as the United States have imposed compulsory recycling on used tires. According to reports, a few years ago, China's used car tires were mostly used for oil refining, due to serious pollution was halted. For tires with worn tread and good carcass quality, the best way to recover is to renovate the tires. There are also "retrofitted tires" made from used tires on the market. However, some tires have poor safety and often cause accidents. Relevant experts indicated that in the future, the registration system for automobile tire repairs will be promoted, a nationwide uniform tire repair networking system will be established, and professional tire repair companies will be able to grasp the tire condition. After unqualified tires reach the end of scrap conditions, they can inject plastics into “rebirth†as “ New tires." "Rubber used tires can be completely reused. Our experimental research is to determine a scientific use method, so that the use of waste rubber tires fully meet the requirements of the indicators, and more secure." Wang Yiqing said. Reporter Wang Dongliang correspondent Feng Kuanxi Schools and enterprises share scientific research results At present, energy-saving tires will be produced by domestic tire companies such as Linglong Tire Company. A scientific and technological innovation result, which has just passed acceptance, can be transformed into productivity. Behind the “quick speed†is the shadow of a property rights alliance between research institutions and manufacturing companies. Tire companies have a large scale of production. New technologies need to be suspended during factory trials and some production processes will be disrupted. Production chaos will be caused, and the test funding provided by schools will not be enough to make up for the loss of tire factories. According to reports, the North Chemical Research Department and related companies share scientific research results, tire companies can give priority to the use of the results or even free of charge, the school and research companies to form a de facto alliance of property rights, in order to promote the progress of the test and increase the enthusiasm of business participation. In addition, the company also provided market information to find the direction for scientific research. 12L Mechanical Balance Type Gas Water Heater 12L Mechanical Balance type Gas Water Heater YONYAN ELECTRIC GAS TECHNOLOGY CO.,LTD , https://www.yonyanchina.com
