Fuel saving 5 of the hottest nano tires will be ma

Nano tire fuel saving 5% will be mass produced and listed with an annual fuel saving of 4million tons

the goal oriented subject of the National 863 plan undertaken by Beijing University of chemical technology and other units - tire high performance 7. The large-scale preparation technology of nano elastomer composites that can be used according to the loading speed required by the experiment has been passed, and a new fuel-saving safety tire has been developed. Equipped with this new nano tire, the fuel consumption of cars can be reduced by about 5% compared with the existing ordinary radial tires. At present, this fuel-efficient tire has entered the stage of mass production and will be on sale soon

"smart" tires: annual fuel saving of 4million tons

yesterday, the window of oil price rise opened again, and the rising oil price has always troubled car owners. "It's convenient to drive, but the oil price can't really hurt." The citizens who live in Tiantongyuan personally think that the verification regulation of the "electronic universal testing machine" is more practical and reasonable. Mr. Dong drives to work by himself, and the average daily fuel cost is about 50 yuan. Hearing that there are tires that can save 5% fuel, he kept asking where they can be sold

in addition to vehicle shape, vehicle weight and engine efficiency, tires are also one of the key links of vehicle fuel saving. When the vehicle is driving, the tire seems to be rolling, but the soft rubber tire squeezes and deforms with the road surface, forming a lot of sliding friction inside, and the increase of resistance will consume more fuel

the tires developed by Beijing chemical industry are "smart". "We have changed the internal structure of the tire tread rubber material, and the intermolecular slip force can be large when braking and small when driving, so as to achieve the purpose of fuel saving." Said wangyiqing, an associate researcher of the State Key Laboratory of organic and inorganic composites of Beijing chemical industry

it is reported that the fuel saving secret of the new tire is the use of solution polymerized styrene butadiene rubber, which has better comprehensive properties than other traditional tire raw materials. In addition, fuel-efficient tires have a secret weapon - white carbon black. Wang Yiqing said that in the past, when manufacturing tires, carbon black was needed to be added to the raw materials. This substance can help the rubber resist ultraviolet rays and prevent the rubber from aging too quickly. However, there is a layer of scales on the surface of carbon black, and the rubber is adsorbed on the scales. When the tire rolls, there will be slippage between them, increasing the friction resistance. The structure of white carbon black is different from that of carbon black, with smooth surface and chemical combination with rubber. When the tire rolls, the friction resistance can be minimized

according to the actual calculation of the sports car field, the new tire saves 5% fuel than the radial tire widely used at present. Based on the national consumption of 80million tons of gasoline in 2011, 4million tons of gasoline can be saved every year and 34.32 billion yuan of fuel expenses can be saved. At present, fuel-efficient tires have entered the mass production stage of the factory, and it is planned to form an annual capacity of one million sets

wear resistant tires: reduce the emission of thousands of tons of PM10 every year

the wear of tires in use will produce dust, which may be one of the sources of PM10. It is reported that at present, the service life of car tires in China is about 100000 kilometers, and the driving wear thickness is about 3mm. From use to scrap, it will wear and generate about 1kg of dust. Beijing chemical industry is developing a kind of wear-resistant tire, which can extend the service life to 150000 kilometers and reduce the dust production by about 30%. According to this calculation, 5million motor vehicles in the city can reduce dust emission by about 1000 tons per year

since a small amount of heavy metals and other auxiliary materials may be added during tire production, the dust formed after wear will affect the health of urban residents

it is learned that the tire technicians of Beijing chemical industry are committed to developing new environmentally friendly tires to reduce the harm of tire dust, such as using environmentally friendly aromatic oil, naphthenic oil and natural vegetable oil extracted from plants such as orange peel and soybean, and reducing the use of heavy metals such as zinc oxide

safe "retreaded tires": it is expected to promote

after the completion of the energy-saving tire project, the three units jointly launched another 863 project, "continuous dynamic desulfurization of waste rubber and technology for preparing radial tires", to improve the utilization effect of waste rubber in tires and reduce rubber imports

at present, China has an annual output of 456million automobile tires, and there is a great demand for rubber

Wang Yiqing said that the United States and other developed countries have enforced the recycling of waste automobile tires. It is reported that a few years ago, China's waste auto tires were mostly used for oil refining, and were stopped due to serious pollution. For tires with worn tread and good carcass quality, the best recycling method is to retread the tires. At present, there are also "retreaded tires" made of waste tires in the market, but some tires have poor safety, which often leads to accidents

relevant experts said that in the future, we will promote the registration system of automobile tire repair, establish a national unified tire repair joint system, and let professional tire repair manufacturers master the situation of tires. After the unrepaired tires meet the scrapping conditions, they can be injected with rubber and "reborn" as "new tires". "The rubber of waste tires can be reused. Our experimental research is to determine a scientific method of use, so that the tires using waste rubber can fully meet the requirements of various indicators and be safer." Wang Yiqing said. Wang Dongliang's correspondent Feng Kuanxin

thus bringing errors to the experimental machine

schools and enterprises share scientific research achievements

at present, energy-saving tires will be mass produced in domestic tire enterprises such as Linglong tire company. A scientific and technological innovation achievement can be transformed into productivity just after passing the acceptance. Behind the "speed" is the shadow of the property right alliance between research institutions and production enterprises

the production scale of the tire company is large, and the new technology test in the factory requires the suspension of some production processes, which will cause production chaos, and the test funds provided by the school are not enough to make up for the losses of the tire factory. According to the introduction, the scientific research department of Beijing Chemical Industry Co., Ltd. shares the scientific research achievements with relevant enterprises, and the tire company can give priority to or even use the achievements free of charge. The school and the participating enterprises form a de facto property right alliance to promote the progress of the experiment and improve the enthusiasm of enterprises to participate. In addition, the enterprise also provides market information to find the right direction for scientific research
