Application of nanotechnology in automobiles

nano is a unit of measurement, and 1 nanometer is one millionth of a millimeter. In such a small space, Wang Zidong, director of the National 863 electric vehicle major special power battery test center, told: according to the current production expansion plan of power battery enterprises, it is actually the basic unit of matter, becoming the space of atoms and molecules. Since the invention of the electron scanning tunneling microscope in the early 1980s, nano science, a micro world research discipline with nano as the unit, has been born in the world. The technology of researching and processing substances in micro structures below 100 nm is called nanotechnology

in the 1990s, nano science has developed rapidly, resulting in nano materials, nano chemical engineering, Nano Mechanics and nano biology. The resulting nanotechnology products are also emerging in endlessly, and began to involve the automotive industry. So, what about automotive Nanotechnology? It should not rise suddenly and quickly

nanotechnology is the core technology of automotive development. Nanotechnology can be applied from car body to wheel, covering almost all of cars. The wide application of nanotechnology in automobiles will reduce the wear and tear of automobile components, reduce automobile consumption and reduce automobile use costs; To a certain extent, it can also eliminate automobile exhaust pollution and improve emissions. Nowadays, many automotive products have begun to adopt nanotechnology, and small nano will make great changes in automobiles

nano paint -- less scratches

beautiful and beloved cars will be ruined if they are accidentally scratched. DaimlerChrysler, an automobile manufacturer, recently announced that a new nano paint for car body spraying will be adopted from the end of 2003 to prevent small scratches during collision

it is reported that the nano paint developed by the company's researchers over four years can form a dense structure on the sprayed car body, which contains many tiny ceramic particles. The test of 150 cars shows that this nano paint not only has 40% higher brightness than the traditional paint, but also has much better performance in preventing scratches when the car body collides slightly with other objects. The new paint will be used on Mercedes Benz e, s, SLK and other series cars in the near future, and this new nano paint will be used on all other series cars of the company since 2004

nano plastics -- higher strength

more and more plastics will be used in automobile manufacturing. Nano plastics can change the characteristics of traditional plastics and show excellent physical properties: high strength, strong heat resistance and smaller proportion. Because the size of nanoparticles is smaller than the wavelength of visible light, nano plastics can show good transparency and high gloss. Such nano plastics will be widely used in automobiles. The wear resistance of some materials treated by nanotechnology is 27 times that of brass and 7 times that of steel

in addition, in addition to being recyclable, nano plastics also have the advantages of long-term UV resistance, stable color and light weight, and are widely used in automotive parts. In automobile exterior fittings, it is mainly used for bumper, radiator, chassis, body outer plate, wheel guard, movable roof and other protective rubber strips, wind proof rubber strips, etc. In the interior parts, it is mainly used for instrument panel, interior trim panel, airbag materials, etc. Relevant industry experts predict that in the next 20 years, nano plastics will replace a large number of existing automotive plastic products, with considerable market potential

higher requirements for process control

nano lubricants -- less wear

wear, fatigue and corrosion are the three main forms of mechanical material failure. The economic loss caused by wear is very huge, and nano lubricant can well solve the problem of mechanical wear. Nano lubricant is a pure petroleum product that uses nanotechnology to improve the molecular structure of lubricating oil. It will not have adverse effects on lubricating oil additives, stabilizers, treatment agents, engine emollients, antifriction agents and other products, but will automatically form a thin film with the thickness of a single atom of pure hydrocarbons on the metal surface of parts. Due to the mutual adsorption between these micro hydrocarbon components when they are removed under the beam, the micropores on the metal surface can be completely filled, and the friction between metal and metal micropores can be minimized. Compared with high-grade lubricating oil or fixed additives, its extreme pressure can be increased by 3 to 4 times, and the wear surface can be reduced by 16 times. Because the metal surface is protected, the wear is reduced, and the service life is doubled

nano gasoline -- lower fuel consumption

energy and environmental protection have always been the key issues in the automotive industry. Nano gasoline has been developed at present, and its biggest advantage is to save energy and reduce pollution. This technology is a gasoline microemulsifier developed by using the latest modern nano technology. It can improve the quality of gasoline and promote the combustion of gasoline to the greatest extent. When using, only add microemulsifier to gasoline in an appropriate proportion. Experts from the automobile transportation energy saving technology testing center of the Ministry of communications believe that after using the gasoline added with the microemulsifier, the fuel consumption of the automobile can be reduced by 10% - 20%, the dynamic performance can be increased by 25%, and the carbon floating and emission of pollutants in the exhaust can be reduced by 50% - 80%. It can also remove carbon deposits and improve the comprehensive performance of gasoline

nano rubber -- more colorful tires

the largest amount of rubber materials used in automobiles is tires. In the production of tire rubber, most of the rubber additives are in powder form, such as carbon black, silica and other reinforcing fillers, accelerators, antioxidants and so on. In terms of powdery materials, nanocrystallization is the main development trend of rubber at this stage

the new generation of nanotechnology has successfully used other nanoparticles as additives, and is no longer limited to carbon black or white carbon black. The biggest change in cars is that the color of tires is no longer limited to black, but can have a variety of bright colors. In addition, new nano tires are superior to traditional tires in terms of strength, wear resistance or aging resistance. For example, the crack resistance of tire side rubber will be increased from 100000 times to 500000 times

the above is only a part of the combination of nanotechnology and automobile manufacturing technology. Theoretically, nanotechnology can be applied to any part of the automobile, including body, chassis, interior decoration, tires, transmission system, exhaust system, etc., which can produce different functional characteristics due to the application of nanotechnology

of course, if all parts of the car can be nanosized, its added value will inevitably increase greatly, but relatively speaking, its cost and price will also increase significantly. Therefore, so far, the truly nano and commercial automotive parts are still very limited. However, there is no doubt that the automotive industry is an important symbol of modern industry. The application of nanotechnology to the development of Automotive Technology in the future will be an inevitable trend, and will also become the guarantee of automotive technology upgrading. (end)
