Green tires need to go through three lanes at high speed

China is the world's largest producer of tires. At present, green tires have become the development trend of the world's tire market, causing the domestic tire industry to pay close attention. At the 2013 China (Guanrao) International Tire and Rubber New Materials Industry Conference held on May 14-15, the participating experts proposed that green tires must go through structural design, adopt energy-saving emission reduction production processes, and raw materials comply with environmental protection requirements. Children can really set foot on the road to rapid industrial development.

At present, China’s automobile development faces three major constraints on fuel consumption, environmental pollution, and traffic safety. According to the data, 20% to 30% of fuel consumption of a car is related to tires, and 24% of car carbon dioxide emissions are related to tires.

Green tires have the advantages of good elasticity, low rolling resistance, low fuel consumption, low heat generation, wear resistance, puncture resistance, etc. Compared with traditional tires, they have many advantages such as environmental protection and energy saving. Green tires attach importance to the use of non-polluting materials to manufacture tires, and strive to extend the mileage of tires to reduce the number of used tires; compared with ordinary tires, green tires also reduce the energy consumption of composite materials by reducing tire quality; Compared with the standard tires, the green tires' rolling resistance can be reduced by 22% to 35%, which can reduce the automotive fuel consumption by 3% to 8%, and reduce the emissions of automobile carbon dioxide and other exhaust gases.

Experts say that the future tire market will be dominated by green tires. At present, the EU green tire mandatory labeling law has been settled, the United States, Japan, South Korea and other basic use is the first voluntary and mandatory labeling system, China's green tire labeling act will also refer to the EU labeling bill system. Therefore, the development of green tires is an inevitable choice for companies. The current European green tire technology has been fully applied to tires for passenger, commercial and all kinds of vehicles; however, in China, the application of advanced technologies is still in its infancy, and only a few manufacturers can produce green tires.

“Green” refers to the tire's inherent environmental protection and energy-saving nature. Now, it is necessary to work hard to create the inherent essence of “green”, which is one of the drafters of the “energy consumption limit for tire unit product” and the senior engineer Lin Zhongming of Hangzhou Zhongce Rubber Co., Ltd. "The tires meet the expectations of society and tire consumers for green protection. He believes that green tires should at least include three meanings: First, the tire manufacturing process requires the use of green materials, to achieve lightweight, low energy consumption, low pollution, low emissions; Second, the tire use process requires low roll resistance, low noise, Low fuel consumption and high grip; Third, used tires can be recycled and used, and the renovation rate is high, which can effectively reduce or eliminate “black pollution”.

First of all, green tires should emphasize low rolling resistance and maintain good wet skid resistance and wear resistance from the performance of the product itself. According to Chen Zhihong, former deputy chief engineer of the Beijing Rubber Industry Research and Design Institute, from a technical point of view, the main feature of high-performance tire structure is flattening. The flattening of the tire structure can reduce rolling resistance, improve tread wear, improve high-speed performance, and improve safety. Studies have shown that the friction generated by green tires can reduce 15% of the braking distance on wet or icy roads, which is of great significance for reducing accidents and casualties.

Second, the production of green tires must adopt clean production, energy conservation and emission reduction technologies. The mixing process is the largest process for power consumption in tire companies. At present, low-temperature one-step mixing has significant energy savings and improves the quality of rubber. Chen Zhihong introduced that the energy-saving production process using low temperature continuous mixing process technology, energy consumption reduced by 27%, production efficiency increased by 200%; using electronic radiation instrument curing technology, applied to semi-steel radial tire fiber curtain, all steel radial tire inner liner rubber , Can save a lot of rubber resources; nitrogen filling high-temperature vulcanization process, increase production efficiency more than 1 times, eliminating the need to build high-pressure hot water system investment. The energy consumption target determined by the mandatory National Standard for the “Energy Consumption Limit of Tire Unit Products” that will be implemented on October 1, 2013 is the unit consumption of tons of tires, which will be all-steel radial tires, semi-steel radial tires, bias tires, Separate evaluation of engineering tires can reflect the true level of energy-saving technologies and energy management of tire manufacturing enterprises.

Again, the raw materials used in green tire production must comply with green and environmental requirements. Du Mengcheng, deputy general manager of Shandong Yanggu Huatai Chemical Industry Co., Ltd., introduced that white carbon black must be used for green tire production because the use of white carbon black can improve the wet skid resistance and wear resistance of tires, and reduce tire rolling resistance, friction coefficient, and tires. Noise, thus reducing fuel consumption and reducing carbon dioxide emissions. Increasing the amount of white carbon, will inevitably increase the amount of some additives. Therefore, the production of green tires should be optimized formula cleaner production, such as the use of higher quality special performance rubber additives, high temperature ozone protection microcrystalline wax, anti-reversion agent and so on. The environmental protection requirements for accelerators are that no N-nitrosamine carcinogens are produced during rubber processing, and no nitrosamine carcinogens are produced during application. At present, the comprehensive performance of vulcanizates is good, and it is increasingly attracting people's attention in the domestic and foreign markets, and is now moving to the market as a substitute for traditional vulcanizing agents.

Cut To Length Line Machine

Process

The sheet is processed in the following steps: decoil the raw material, feed with a fixed length via the servo motor, shearing it with various shearing tools into sheets of various types according to the drawing and then piling them on the stacking table via the conveying mechanism and the arranging mechanism.
