Shanghai Honglei Fine Powder Complete Equipment Co., Ltd. announced in Shanghai a few days ago that after 10 years of development, the company has finally achieved the use of waste tires and waste rubber as raw materials, and will be crushed at room temperature, mechanically, fully automatic, and fully closed. The fine rubber powder was successfully modified into a plastic rubber powder and became a rubber raw material that can replace natural rubber and synthetic rubber. The world's first 10,000-ton-class plasticized plastic powder production line with this technology was put into operation at the end of last year in Jiangyan City Honglei Rubber Co., Ltd. This set of "HL use of waste tires to produce rubber raw materials complete sets of equipment" to achieve "one end of waste tires into the other end can be rubber products out", become China's waste tire recycling recycling of the demonstration projects.
Cheng Yuan, vice president of the China Tire Renovation and Recycling Association, said after Jiang Yan Honglei Company's investigation that the history of rubber recycling in the world is being rewritten - after the natural rubber and synthetic rubber, the plastic powder developed by Honglei will become the first Three sources of rubber resources. According to reports, the use of the technology to produce different varieties of rubber powder, priced at 6000-9000 yuan per ton, compared with natural rubber and synthetic rubber competitive. At present, the use of domestic reclaimed rubber large Taiyuan Rubber Plant has been widely used this plasticized rubber powder, general manager Xue Jing said that the plasticized rubber powder can completely replace the imported raw materials, individual performance even more than natural rubber and synthetic rubber, with Its raw materials, the cost per kilogram of products can be more than 0.6 yuan.
According to Li Jing, Director of the Department of Environmental Protection under the National Development and Reform Commission, at present, 70% of China's rubber raw materials need to be imported. It is the world's largest consumer of rubber and its annual consumption has exceeded 5.5 million tons. Since 2000, the price of raw rubber in the international market has continued to rise, and is currently over 30,000 yuan per ton. Rubber companies are overwhelmed. At the same time, China is the largest producer of automobile tires in the world, with an annual output of more than 430 million tires and more than 140 million wasted tires annually. With the rapid development of the automobile industry, environmental protection and resource pressure brought about by waste tires are increasing.
In order to realize the recycling of waste tires and the efficient use of high-value resources, in 1998, the Shanghai scientific and technological personnel Bao Guoping Xiahai established Honglei Fine Powder Equipment Co., Ltd. After eight years of hard work, the company developed the first set of normal temperature and pressure fine powder production technology and equipment, and obtained a number of invention patents and awards. However, due to its lack of activity, this finely-vulcanized rubber powder can only be used as a filler, and its application is limited. At present, there is an excess of domestic production capacity. Therefore, opening up new ways for the recycling of used tires has become a major and pressing issue.
In the past two years, Bao Guoping led the scientific and technical personnel to continue research and development at Jiangyan R&D base. After numerous tests, he finally developed the application technology and auxiliary equipment manufacturing technology for the plastic treatment of vulcanized rubber powder, that is, physical treatment and incorporation of a small amount of chemical promotion. After the agent, the elastic vulcanized rubber powder is modified into a plasticized form, which can be compatible with natural rubber or synthetic rubber after the rubber compound, or can be used as an alternative. It can partially replace the natural rubber and synthetic rubber materials of high-grade rubber products, and can also be used in full. To produce mid-range rubber products. After testing, its tensile strength, elongation, wear, hardness and other indicators have far exceeded the original standard of rubber powder. And a full set of equipment and normal temperature and pressure fine powder production together into a pipeline, the entire process of clean production. At present, the project has obtained 10 core technologies and has obtained a number of national patent authorizations.
How to promote the recycling of waste tires to the market and the society, Bao Guoping, Chairman of Honglei Company, proposed a new idea for the development of “industrial parksâ€. Bao Guoping said that in order to promote the recycling of waste tires in the form of "industrial parks," Hong Lei Company provided parks with comprehensive services in philosophy, planning, design, technology and equipment manufacturing, which is a good form of investment and quick results. Last year, the 20,000-ton plasticized plastic powder and rubber product industrial park of Suzhou Honglei Rubber & Plastics Technology Development Co., Ltd. has been included in the national “Eleventh Five-Year†technology support project, and is planned to be completed within the year; Honglei Rubber, established in Hejin, Shanxi Province Products Co., Ltd. will build an industrial park of 30,000 tons of waste tires. The first phase of the project will be completed during the year. At the same time, a 100,000 ton-class plasticized plastic powder production base is under preparation in Xiangyang, Shanxi; in Taizhou, Jiangsu, the original Taizhou Rubber Co., Ltd. As the leader, the factory will build a 10,000-ton cold overturned rubber production base and a rubber compounding center.
The recycling of waste tires will eventually become a new industry, Bao Guoping firmly believes. However, to develop it into an emerging industry, it is necessary to do a good job in three areas: First, to promote agricultural tires, tires and other applications; Second, to enter the world famous brand tire companies; Third, to become one of the international standard rubber, enter the futures Market transactions.
Plasticized plastic powder alleviates resource and environmental crisis
Waste tires are called "black pollution" and their recycling technology is a world-class problem. At present, the global old tire refurbishment accounts for only 10% of new tires, which is approximately 5% in China. Waste tires are physically crushed and processed into fine rubber powder, used in plastic runways, and most of them are burned, stacked, or Landfilling seriously pollutes the environment. At the same time, as the world's largest consumer of rubber, China is facing an increasingly severe rubber resource crisis. In this context, a new technology, “HL production of rubber raw material complete sets of equipment using waste tires†came into being. By thoroughly renovating the conventional processing route for used tires, the waste tires were processed to be comparable to natural rubber and synthetic rubber. The plasticized plastic powder is expected to achieve the dual benefits of efficient resource utilization and environmental protection, and to develop a third source of rubber for the development of the rubber industry in China.
