How to deal with the scrap tire
- Jul 26, 2017 -

According to a statistic, the production of scrap tires in China will reach 20 million tonnes by 2020. The growing "black pollution" to China's already fragile ecological environment, therefore, the treatment of waste tires caused by "black pollution" urgent. But in the face of such a large number of waste tires, how to realize the treasure?

China's scrap tire production in the world first
According to statistics from the Ministry of Environmental Protection, as at the end of 2014, China's motor vehicle ownership amounted to 264 million vehicles, of which 154 million vehicles, motor vehicle drivers broke through 300 million. Ministry of Public Security of the Department of Management, with the rapid economic and social development, the demand for rigid cars, China's car ownership will continue to show a rapid growth trend. However, with the popularization of automobiles, waste tires and other rubbish also gradually increased. Sources said that China's tire production has been in the forefront of the world for 10 consecutive years, the annual production of scrap tires is also the world's first. Industry insiders predict that the production of waste rubber and scrap tires in China will be more and more. Incomplete statistics, in 2013, the production of scrap tires in China has reached 299 million, the weight reached 10.8 million tons and the annual rate of about 8%-10% growth. On the one hand is the increasing volume of tire production data, on the other hand it is to make more and more headaches of waste tires safety accidents and pollution problems.

What is the magic of waste tires
Recycling is a more acceptable way of dealing with people. It is understood that with the progress of science and technology, countries in the world have been actively studying and opening up new ways of comprehensive utilization of waste tires. Especially in recent years, the public awareness of environmental protection has been increasing, the use of waste resources to cultivate new industries, the realization of economic sustainable development has become the consensus of the world. Relevant data show that the current comprehensive utilization of waste tires mainly have the original system, the renovation of waste tires, thermal energy utilization, heat decomposition, production of recycled rubber, such as the production of rubber powder and many other methods.

4 strokes to deal with scrap tires
(1) The direct use of the future treatment of tires after the combination of installation, can be used for coastal wave prevention, slope protection, artificial reefs, soil and water conservation materials, fender, beacon Towers, floating terminals, etc., can also be directly laid in the landfill at the bottom of the impervious film as a protective layer, but also can be simply transformed into the construction of mud barrels, sports games equipment, road mats, track buffer materials, pasture fences and so on. Because these use does not need the advanced technology, the implementation is easier, but this kind of utilization must indulge in the choice of place, the usage is very limited, to solves the big most waste rubber, the waste wheel utilization question only has the small function.
(2) The renovation of tires is the worn-out tires have worn, can not use the outer layer of discarded tires to cut, paste on the plastic material, and then vulcanization, you can be able to reuse the refurbished tires. In the use and maintenance of good conditions, a tire can be refurbished many times, specifically, nylon cord tires can be renovated 213 times, steel wire tires can be renovated 3-6 times. Each renovation, can regain the equivalent of new tires life 60% 90% of the service life, an average mileage of about 50,000-70,000 km, through multiple renovation, at least to make the total life of the tire $literal times longer, that is, a tires after several renovations at least equivalent to 2-3 wheel Shan. The raw material used to renovate an old tyre is only the equivalent of a l5%-30% of new tires, the price being $number.
(3) Solid waste fuel used tires is a high calorific value material, each kilogram of heat is 69 higher than the wood, 1 0 higher than bituminous coal, higher than 4 of Coke. The waste tires are broken, and then mixed with various combustible waste materials according to a certain proportion, the solid waste fuel (RDF) is prepared for blast furnace injection instead of coal, oil and coke as fuel for burning cement or for coal and thermal power generation. At the same time, the method also has a byproduct-carbon black generation, after activation can be used as a reinforcing agent again for the production of rubber products.
(4) The production of reclaimed plastic rubber is used to be used for the process of crushing, heating and mechanical treatment, so that its elastic state becomes plastic and viscous can be vulcanized rubber. Since the late 1980s, the developed countries have transferred from the production of recycled rubber to rubber powder activation modification or the direct use of fine rubber powder, while the use of waste rubber production in China is the main use of the way, the current renewable gum accounted for 95%, activated plastic powder and fine powder accounted for 5, far behind the developed countries.
