Energy-intensive industries

The tire industry is an industry with huge energy consumption. From the initial raw material processing link to the product production link to the final product use link, a large amount of high-carbon fossil energy is consumed. First of all, most of the main raw materials of the tire industry are derived from petrochemical energy, including synthetic rubber, carbon black, nylon fiber and other types of petroleum cracking products. Among them, about 70% of the raw materials of synthetic rubber come from petroleum. The process of refining natural rubber also consumes a lot of energy such as coal and electricity. At present, the tire industry's consumption of synthetic rubber has accounted for more than half of the total global synthetic rubber output, and the tire industry has become one of the main consumption industries in the upstream petrochemical industry. Secondly, in the production and processing of tire products, such as mixing, vulcanization and other technological links, it is inseparable from coal, electricity and water to provide power protection. At the same time, due to the large volume and quality of tire products, the increase The transportation cost of the tire industry makes tire products consume a huge amount of fuel in the transportation link. Finally, tire products consume a lot of energy during use. Tire products are mainly used in automobiles. Although the engine is the main component of automobile fuel consumption, the proportion of tire products in automobile fuel consumption cannot be ignored. According to experimental measurements, when a car is running at a speed of 100 km/h, the amount of fuel consumed to overcome the rolling resistance of the tire accounts for 20% of the total fuel consumption of the car; in a truck, this proportion can reach 30% or even more. High, that is to say, tires account for more than one-fifth of automobile fuel consumption.
