Plastic leads cars toward a low-carbon, environmentally-friendly vision
Today, all walks of life are all in the effort for the realization of energy conservation and environmental protection, it is not only in order to adapt to the environment, but also reduce the production cost, the pursuit of industrial upgrading and joint performance of competitive advantage in the future. The automobile industry, which is closely related to our life, is also carrying out this concept deeply. Plastic, a powerful wing, is leading the car toward a low-carbon, environmentally-friendly vision.
Lightweight to achieve low energy consumption
Automotive lightweight brings not only the overall weight is reduced, on the premise of guarantee body strength and safety performance, it also effectively improved the car power, reduce the fuel consumption, and reduces the exhaust pollution. According to the experiment, if the weight of the car is reduced by 10%, the fuel efficiency can be increased by 6% to 8%. Many cars in the world now use more than 120 kilograms of plastic, and some are even taller. The plastic use of the German Mercedes Benz has reached 150 kg/s. Some domestic cars have already reached 90 kilograms of plastic. In addition, the application of EMS-GRIVORY advanced polyamide (nylon) products in automobile is an example. The data shows that the application of each alternative metal can save 50% cost and reduce weight by 70%. Today, many countries have used the amount of plastic in cars as an important indicator of vehicle design and manufacturing standards.
From foton automobile engineering research institute, says Mr ShangGongBo along with the development of automobile energy conservation and emissions reduction and the vehicle lightweighting demand growth, plastic is widely used as raw materials in the field of auto parts, from the interior parts to exterior trim and structural components, plastic parts of the figure can be seen everywhere. Today, fukuda has a large number of non-metallic materials, including 6%-8% of the use of heavy card commercial vehicles in China, and 17% to 20% of the use of suvs and other passenger vehicles. Hyundai motor widely used new materials, body structure and design method of the traditional will no longer apply, and the design method based on the principle of biology can further reduce the number of body parts, and can prolong the service life of them. In the future, various high performance composite materials will be combined with the design of the overall innovative structure of auto parts and body parts, and will push the efficiency of automobile lightweight to a more perfect level.
Research on environmental performance has been deepened
Through when the increasing use of lightweight materials such as plastics, as well as the constant innovation of advanced design technology to achieve the upgrading of its lightweight at the same time, the plastic as itself a special chemical properties, the study of its environmental performance has been deeply. The environmental protection of plastic in automobile application will be mainly reflected by its recyclability and low VOC (volatile organic compound). Faw technology center/ms beryl chinghwa lee says the national center for quality supervision, inspection, some of the low VOC plastic material on the market at present, has been used in car production, but most of the products were not mature application conditions, but low VOC materials is the mainstream of future materials, should serve as an important development direction of material technology. In order to achieve this trend, the development of materials from plastic technology to materials will face innovative challenges. How to follow the principle of LCA PrinciplesofLifeCycleAssessment) (product life cycle assessment principles, correctly handle the relationship between human and earth, and productivity, realize the efficient utilization of resources of plastic industry products, environmentally friendly, recyclable and renewable, how to provide good solutions of sustainable development, and how to solve the problem of the production cost of biological substitutes that will be companies need to think about and the direction of efforts.
With the continuous improvement of environmental regulations on automotive materials, the standards for the future use of vehicles will be stricter. In adsale group last year to host the third CPRJ automotive plastics technology BBS ", changan automobile engineering research institute, vice President of the cao Mr Watanabe said, according to the regulations, since 2014, a new authentication model can recovery rate reached 90%, the material utilization rate is not lower than 80%, in 2017, is up to 95% and 85% respectively. We will go from excessive pursuit of material high strength, high toughness, gradual change to examine the comprehensive performance of material, also will pay more attention to environmental performance of expression. At the same time, in view of the plastic products of some new testing methods are also appear constantly, such as the smell test, condensation test, formaldehyde, total volatile matter content, etc., through the implementation of these measures will help the car more tend to environmental protection material, of course, also control each link in production of plastic products and the selection of raw materials put forward higher request, this is also for plastics manufacturers put forward new challenge.
