Zhejiang Province to deal with the use of discarded tires, a leading international technology

Zhejiang Province, the development of circular economy and innovative bright spot, with a normal temperature method in dealing with million-ton waste tire rubber powder meticulous production line model, recently completed and put into production. Discarded tires in the shape of the flour made from fine powder, this powder-type development of the prefabricated rubber track, has been included in the 2008 Beijing Olympic Games pre-selection of products sporting goods catalog. These two technology industry filled the gap, with ambient temperature method to deal with discarded tires reached the international advanced level of technology for our country in this area lay the foundation for comprehensive utilization of resources.



Act of discarded tires at room temperature processing technology from Zhejiang Shengzhou, Zhejiang green rubber ring Engineering Co., Ltd. developed with 5 national patents, has been formed complete sets of equipment production capacity. The use of technology and complete sets of equipment, at room temperature can be discarded tires to smash the fineness of 40 to 200 heads of the purpose of fine powder, no secondary pollution, and automatic separation of wire, fiber, production equipment has been exported Canada, the United Arab Emirates, Japan and other countries. The international community will deal with discarded tires to more than 40 heads of fine powder, the technology is frozen with liquid nitrogen refrigeration or air law, to be 140 degrees below zero in the following conditions to complete. In contrast, in Zhejiang Province's first law to deal with discarded tires at room temperature technology, investment, which is only a quarter of the cost of production and energy consumption is only one-third of the latter, and no secondary pollution. This is our country's handling of discarded tires and fine powder processing opened up broad prospects.



The successful development of the treatment of discarded tires at room temperature technology, and equipment manufacturers to achieve industrialization, Zhejiang, Central extension of the Green industry chain to build a production line model, to deal with discarded tires and treated fine powder for further processing, prefabricated development of the rubber-based standards Runway and other products. The products have been adopted by the IAAF and national sporting goods product quality inspection, 5 indicators better than the international standards. Products with good weather, the professionalism, safety and environmental protection, the traditional plastic runway of the new-generation products that are widely used in indoor and outdoor track and field stadium, has been included in the 2008 Beijing Olympic Games pre-selection of products sporting goods catalog. Zhejiang Province to develop this product from Italy for a long time to break the monopoly on the international market situation, price is only one-third of similar products in the world, a huge market prospects.



With car ownership of the rapid growth of the piles of discarded tires, a "black pollution." At present, each of the discarded tires have been more than 100,000,000, and an annual double-digit rate. In fact, the whole body are the discarded tires to tire, for example, tires with 22-24% fibers such as nylon, to deal with post-processed into nylon particles, for Machinable plastic products, priced at about more than 2000 yuan per ton. With 16-18 percent of the wire can be used as a spring of high-quality raw materials, taking out the steel beam, the price per tonne of 1200-1300 yuan, Grated steel price per ton in the 500-600 yuan. With 58-60 percent of the mixture of rubber, rubber and processed into a variety of renewable fineness of vulcanized rubber powder. This tire rubber powder meticulous alternative Synthetic and natural rubber, producing a variety of rubber, tire rubber powder meticulous tons sold at about 3000-3500 yuan, and tons of Synthetic and natural rubber price of about 13000-15000 yuan , 4 times higher. At the same time, tire rubber powder can be widely used in fine rubber powder modified asphalt roads, water-proof materials, coatings, and polymer composites, flexible floor, rubber, and so on the runway, economic, environmental and social benefits were enormous.



The lack of mineral resources in Zhejiang Province, the active use of waste materials, the development of circular economy, industrial economy of Zhejiang is an important measure of sustainable development. At present, the province in the waste paper, scrap steel, copper, stainless steel waste, waste plastic recycling in areas such as walking in the forefront of the country, forming a rather special stainless steel smelting, copper, paper and other industries. Waste tire processing technology and equipment development and the success of industrialization, Zhejiang Province in this field to create new industries and lay a solid foundation for the government in economic policy, planning and guide them in such areas as support and promotion for the building of the province's resources A conservation-minded industry to create new growth points.
