At present, the green tire industry in Shandong is booming and in full swing . More than 80% of the radial tire production enterprises in the province can meet the requirements of the first phase of the EU labelling law (November 1, 2012); but with the latest international technology In contrast, there is still a large gap, in addition to Qingdao Soft Control Co., Ltd. has begun the research of tire automation equipment, most of the company's radial tire production are using traditional technology. "A few days ago, when reporters were interviewed by the Rubber Industry Association of Shandong Province, Zhang Hongmin, the president of the association, said with uneasiness.
According to the tire labeling regulations promulgated by the European Commission, since November 1st this year, car tires, light truck tires, truck tires and bus tires sold in the European Union must be labeled to indicate the tire's fuel efficiency, rolling noise and wet grip. The grade.
Zhang Hongmin believes that this is both a challenge and an opportunity for the tire industry. Related companies should maintain a clear understanding, further accelerate the pace of technological innovation in green tires, and catch up with the world's advanced level as soon as possible.
Tire giants are showing their strength
According to Zhang Hongmin, the so-called “green tires†refer to the requirements for energy saving, environmental protection, and safety during the entire cycle of tire raw material use, product manufacturing, and use.
He told the Herald reporter that in recent years, tire companies in our province have made important progress in responding to the EU labeling law and the development of green tires.
The exquisite green tires developed by the Linglong Group have reached the European Union's labeling law C/C/2 requirements, which are equivalent to those of Michelin and Dunlop, and reduce the rolling resistance of the existing ordinary tires by more than 30%, meeting the requirements of world-class automotive plants and reducing fuel consumption. 3%-5%.
Delta Group makes full use of qualified laboratories and testing sites at home and abroad to test tire rolling resistance, noise, and wetland grip. From the test results, the three types of tires exported to the European Union (C1, C2, C3) all meet or exceed the requirements of the first phase of the EU labelling law.
Race Wheels actively promotes the safety and environmental certification of tire products. The company's products exported to the United States have passed the Smartway certification of the US Environmental Protection Agency, and are the second tire company in China that has passed certification. In order to successfully pass the product certification, the company's technical personnel optimize the tire structure design and formula, reduce the tire's rolling resistance and dynamic heat, so that the tire in energy-saving, environmental protection and safety to a new level.
Shandong Jinyu Tire Group Co., Ltd. has made green tire development in terms of formula, technology, structural design and testing, and has made breakthrough progress. More than 70 models of its tires were tested by the Ministry of Transport of the Netherlands, and the wetland grasping force reached Class A, rolling resistance reached Class B, and the noise was close to the world's advanced level.
The gap is still more obvious
In spite of this, in Zhang Hongmin's view, compared with the latest international technologies, there are still large gaps in the design, production, and technology of our province's green tires, and we need to catch up.
According to reports, in recent years, the world's tire production technology has made breakthrough progress, mainly reflected in the three major aspects. The first is to make breakthroughs in design methods, use large-scale computers, finite element analysis and simulation and other means to greatly shorten the product design cycle, improve efficiency and reduce costs.
Followed by major changes in the production process, to the low energy consumption, low pollution, high efficiency, high precision, full automation direction, reducing the impact of human factors, greatly improving the consistency of the product.
“The new technologies of the major tire companies in the world have their merits.†Zhang Hongmin cited an example. The Michelin C3M technology of France can achieve the integration of command, control, information, and manufacturing, resulting in a 50% savings in infrastructure investment costs and an area reduction of 50%-90. %, Operators reduced by 50%-90%, raw material consumption decreased by 9%; US Goodyear's IMPACT technology can improve processing accuracy by 43%, production efficiency by 70%, employees by 42%, cost reduction by 20%, raw material savings 15%; The MMP technology of the German Continental Company integrates the four major processes of the traditional production process into two large blocks, which can reduce production costs by 60%.
For another example, the Italian company's MIRS technology will compress the four major processes into three major processes, which will reduce the factory floor area by 80%, infrastructure investment by 15%, cost savings by 25%, and production efficiency by 80%.
In view of this, Zhang Hongmin expressed the hope that the tire enterprises in our province could give full play to the only national "tire craft and control engineering technology research center" and two "tire advanced equipment and key materials national engineering laboratories" to actively develop green tire production. The new technology and new equipment promote the progress of green tire technology.
