Automobile plasticization boost the development of plastic industry
Automobile light weight is inevitable trend, and the automobile plastic trend takes shape, which means that the application of plastic parts of the car also must be boosted, the whole industry will have high speed development, promising prospect. It is estimated that a car will lose 10 percent of its own weight and fuel consumption by 6 percent to 8 percent, while carbon dioxide emissions can be reduced by 5 percent to 6 percent. Therefore, in energy conservation and emission reduction, the light weight of cars is the undisputed hot topic. In this context, the plastic material with low density is an effective way to reduce the weight of the body. In the same size of auto parts, plastic products are generally 30%~40% less than steel in quality, with a fairly obvious lightweight advantage. Besides, plastic material has the advantages of large design space, low manufacturing cost and wide function. Therefore, in the breakthrough of technology, the application of automobile plastic products gradually increased. From dressing to the inner decoration, from function to structure, and even appeared all plastic body, plastic products in the car is becoming more and more widely, the coverage of automotive plastic industry high-speed development. At the same time, the amount of plastic products in cars is gradually becoming a symbol of the development level of a country's automobile industry. Globally, Germany and Japan are leading other countries in the amount of plastic used in cars. According to statistics, the average German car USES nearly 300kg of plastic, and the average Japanese car USES plastic for 100kg. In comparison, only 70kg of plastic products are used in every car in China, and there is a lot of room for improvement in the future. As can be seen from the data, even in Germany, where the automobile industry is developed, the use of plastic products is still limited. The reason is that there are many obstacles to the promotion of automobile plasticization. On the one hand, the high strength and high cost performance materials supply the problem. Compared with metal, the plastic fatigue period is shorter, the aging phenomenon is severe in high temperature or in contact with gasoline, and the application strength of the transmission part is not enough. In addition, the cost of automotive plastic products remains high under technical constraints. On the other hand, automobile plasticization also faces the problems of production and renovation cost and recycling. In other words, car manufacturers have low recognition of the plastic parts of the car in the best interest. However, in general, under the pressure of energy conservation policy and product cost, automobile plasticization is the trend, and the application promotion of automobile plastic parts will continue to be promoted. Constantly breakthroughs in technology, material quality and the process continued ascension, automotive plastic problems will be solved step by step, and by the government, car companies, suppliers and the joint efforts of the material manufacturer towards large-scale popularization and application stage, the future development prospect.
