New technology to save waste rubber "The comprehensive utilization of waste rubber is an important link in the rubber industry's industrial chain. It can not only improve the processing performance of rubber products, but also effectively provide raw materials for China's rubber industry. At present, China has become One of the countries with the largest amount of waste rubber in the world, but the comprehensive utilization rate is only about 65%, and there is still a certain gap compared with the utilization rate of more than 80% in developed countries. It is predicted that by 2020, China's waste rubber The amount of production will reach more than 6 million tons.Therefore, using advanced technology and innovative products to change and improve the utilization rate of waste rubber, vigorously implement the brand strategy in the waste rubber recycling industry, protect the environment, turn waste into treasure, is to achieve the rubber industry can An important part of sustainable development.†August 31, at
At the meeting of the China National Forum on the Recycling of Scrap Rubber and Recycling Technology, Si Hongzhen, chairman of the China Rubber Industry Association, said in an interview with reporters.
At present, the main methods for the comprehensive utilization of waste rubber in China are tire renewal, production of reclaimed rubber and rubber powder. Among them, the production and utilization of reclaimed rubber has become a new force in the comprehensive utilization of waste rubber in China. It is reported that China's reclaimed rubber production has basically adopted dynamic desulfurization technology. The technology is mainly based on independent innovation, and it ranks among the world's leading players in terms of environmental protection, high efficiency, and energy conservation. In 2005, the output of reclaimed rubber in China reached 1.45 million tons, and the utilization rate was about 95%. It provided raw materials for the rubber industry of more than 480,000 tons, equivalent to 90% of the output of China's natural rubber, and also reduced nearly 2.2 million tons of the year. Accumulation of solid waste effectively cleans up the environment. Tire renewal technology transformation began. In the late period of the "Tenth Five-Year Plan", China's tire manufacturing enterprises regard tire retreading as an important part of the development of circular economy. Well-known companies such as Delta Group, South China Tire, Shanghai Tire and Guizhou Tire have all set foot in this field. They rely on strong economic strength. With technological advantages, a high starting point involved tire retreading production, thus bringing new life to China's tire retreading industry. In 2005, the number of tires being retreaded in China was about 8 million, which only accounted for 3.2% of new tire production. The number of pre-cured tire treads representing the world's advanced level was only about 1.5 million, which was far below the level of developed countries. The production and utilization of rubber powder presents a good situation. Since the middle and late 1990s, the successful development of the normal-temperature fine powder production equipment with Chinese characteristics has enabled the rubber powder manufacturing technology and output to be greatly improved in China, and a number of professional enterprises with certain production scale have emerged. In 2005, China produced a total of 220,000 tons of rubber powder. This figure does not include 1.2 million tons of products as raw materials for reclaimed rubber production. At present, the application of rubber powder has also been promoted in three other areas: a large number of applications for the production of waterproofing membranes; batch production of rubber products such as rubber sheets and the production of agricultural tires and load-bearing bias tires; and pilot applications for road laying, such as Enterprises such as Nanjing Donghao Rubber Powder Co., Ltd. participated in the “Application and Research of Rubber Powder Modified Asphalt in Highway Engineering†organized by the relevant national ministries and commissions and opened up new areas for the application of rubber powder.
In the past three years, China's waste rubber comprehensive utilization industry has paid more attention to the development of new processes and new equipment while stabilizing product quality, and has directly translated many research results into productivity, which has reduced production costs and improved the economic efficiency of enterprises and markets.
In terms of competitiveness, etc., significant results have been achieved, and many products have also been exported in large quantities. Such as Shanghai Xiaoyou Rubber Co., Ltd. R & D and production of Xiaoyou brand odorless reclaimed rubber, not only by Shanghai as a high-tech achievements conversion project, and the product has been in short supply; Nantong Back Rubber Co., Ltd. R & D and production of Nanhui fine tires Recycled rubber and non-polluted tire reclaimed rubber have met the special requirements of users in terms of odor and fineness. The products have been exported to developed countries in large numbers.
Geng Hongzhen said that although the comprehensive utilization of waste rubber in China is on the rise year by year, there are still some problems that need to be solved in the development of the industry. First of all, the lack of relevant policy support, including tax incentives, industry development promotion policies, etc. Secondly, the development of "one small earth and three small" namely the land-based oil refinery and the small rubber powder plant, the small reclaimed rubber plant and the small retreading plant has led to shortage of used rubber, especially used tires, and serious environmental pollution. Third, transportation
Overloading, tires running in the end of the habit, resulting in too little for the refurbished fetal sources. Finally, the lack of effective publicity and promotion measures has resulted in retreaded tyres not being recognized by consumers. The prices of these products are low and their quantity is low. Looking at the global developed countries, the quality of retreaded tires has been widely recognized by consumers and is the main reason for the development of this product. For example, the refurbishment rate of U.S. aviation tires reached more than 90%, and the high-precision fighter F-14 also used retreaded tires; France's Michelin company currently has more than 80 overhauled tire factories in the world.
In order to further dig out the comprehensive utilization of waste rubber in China, the rubber industry will serve the economic development of China better. At the forum, the participants agreed that during the “Eleventh Five-Year Plan†period, the development focus of comprehensive utilization of waste rubber in China should be locked In the following aspects: First, we must solidly make deep processing of used rubber, develop and develop better quality, cheaper, high-tech, rubber products with reclaimed rubber and rubber powder as main raw materials; The production of powder is to increase the proportion of rubber powder and reclaimed rubber, which is only 1.4:10 at present, and efforts are made to expand the powder in non-rubber products, especially
The application on the expressway; the third is to guide tire manufacturers in the production of new tires at the same time, increase efforts to enter the retread industry, focusing on research and development of radial tire retreading process, accelerate the development of pre-cured tread and medium pad, to replace imports, in As soon as possible, domestic production was carried out on the retread production and testing equipment. Through hard work, the new tire industry will be integrated with the retreading industry to realize the sound operation of the tire recycling industry chain. Fourth, we must create conditions, start low-temperature thermal cracking and other forms of waste rubber research and development and pilot projects. They also called on the state to issue a number of measures, such as the early enactment of the Regulations on the Administration of Waste Rubber Recycling, the establishment of a special fund to encourage the recycling and use of used rubber, and the resolute elimination of local oil refining, and promote the standardized and benign use of waste rubber in the domestic industry. development of.
In order to help Fuyou and strengthen the promotion of waste rubber recycling industry to accelerate brand building, the China Rubber Industry Association also recommended to the society 18 brands of high-quality reclaimed rubber and plastic powder.
