In the 2010 Petroleum and Chemical Industry Science and Technology Award recently announced, three projects in the field of comprehensive utilization of used tires were awarded. Among them, the technology development and application projects of high-value remanufactured complete sets of tires for special-purpose tires jointly developed by Qingdao Science and Technology University, Qingdao Tiandun Rubber Co., Ltd. and Shanghai International Port (Group) Co., Ltd. won the second-class scientific and technological progress of the Petrochemical Association. Awards; High grade reclaimed rubber for tires and its preparation technology developed by Anhui Huiyuan Rubber & Plastics Technology Co., Ltd. and non-coal tar environment-friendly reclaimed rubber developed by Jiangxi Lixin Rubber Co., Ltd. won the third prize for scientific and technological progress. The used tire special remanufacturing equipment technology project is an “Eleventh Five-Year†national science and technology support plan project. This project has refurbished and remanufactured large waste port tires, so that its performance index has reached the standard of imported new tires, and its life cycle is also Far above the new tires, it created a precedent for the remanufacturing of large-scale port machines tires at home and abroad. Shanghai Pudong International, Shanghai Mingdong, Shanghai Zhendong, Shanghai Hudong and several other companies using container terminal companies stated that their transportation costs have been greatly reduced. Bao Qifan, vice president of Shanghai International Port Group, said that the implementation of this project has laid a solid foundation for Shanghai International Port Group to develop a low-carbon economy and build a green port. One of the innovative points of high-grade reclaimed rubber for tires and its preparation technology is the production of reclaimed rubber using 12-mesh large-size waste tire rubber powder as raw material, and the production of traditional reclaimed rubber mostly uses 30 mesh or even smaller particles. Diameter of rubber powder. In this way, it not only saves more than 50% of the electric energy consumption, but also reduces the degree of heat aging of rubber powder and effectively improves product quality. In addition, Anhui Huiyuan Rubber & Plastic Technology Co., Ltd. also took the lead in using free radical neutralization aids, ie stabilizers, in the production process of reclaimed rubber, which greatly improved the product's stability. According to Xu Xiqing, chairman of Huiyuan Rubber & Plastics Co., Ltd., at present, this high-grade reclaimed rubber has been used by Anhui Jiatong Tire Co., Ltd. and other enterprises for the production of all-steel radial tires, replacing some of the natural rubber, and has achieved remarkable economic benefits. Ecological Benefits. Yangen Yuan, chairman of Jiangxi Lixin Rubber Co., Ltd., told reporters that non-coal tar environment-friendly reclaimed rubber uses waste radial tires as raw materials and adopts a non-coal tar regeneration process formula, which has the advantages of energy saving, environmental protection, and safety. It is now widely used in tires. Tread rubber production.
