Over the years, the number of people who own private cars has become more and more, and it can be seen from the community, streets and roads that cars have become a fast consumer of people.
The car industry is booming and demand for tyres is growing at a rapid clip.
Chinese tire manufacturers are also growing, and tire consumption is growing rapidly.
With the development of the automobile industry, more and more waste tires are produced.
How to turn waste tires into treasure, and then use it as a problem to be solved urgently.
The secondary use of waste tires can protect the environment, save resources and guarantee the sustainable development of our national economy.
The recycling of waste tires in our country is mainly used for the production of reclaimed rubber, and its production capacity is over one million tons, ranking first in the world.
Secondly, it is used for the production of rubber powder. The annual output is about 50,000 tons, and the capacity has reached 300,000 tons. The market capacity is still to be developed twice.
In order to maximize the effectiveness of the use of used tires, the international practice of retrofitting is usually adopted.
The authority of the environmental protection organization to the world of the eia report lists the various treatment methods of waste tires, the tire turn to get the best points, in terms of six negative impact on the environment, tires refurbished minimal impact.
The conclusion is that the tire reconditioning is the most practical and feasible method for the environmental protection of waste tires.
Under the condition of using and maintenance of good, a waste tires to tire renovation for many times, including nylon cord scrap tire can be 2-3 times tires refurbished, steel wire meridian waste tires can be 3-6 times tires refurbished.
For each refurbished, the equivalent of 60 to 90 percent of the new tires can be regenerated, with an average mileage of 50,000-70,000 kilometers.
Through several renovations, the total life of the old tires can be extended by 1-2 times.
The retrofit a scrap tire compared with the production of a new tire (9.00 R20, for example), can save rubber 9 kg, 4 kg of carbon black, steel wire tire cord 3.4 kg 18 kg, 1.75 kg steel, oil, the value of the resources consumed the equivalent of a new tire production by 15% ~ 30%, 20% ~ 50% of price for new tires.
It is understood that due to the scrap tire recycling, storage, processing difficulties, traditional materials recovery department never covered will waste tyre recycling, countries also have no relevant policies and regulations, the long-term no waste tires recycling channels and recovery of the main body, basic by private individual business households scattered, quantity is little, and can't provide regular sales invoice, to the tyre retreading industry bring unnecessary trouble, increase the tyre retreading industry's operating expenses.
No matter from which Angle analysis, therefore, should establish a unified, the trading center of discarded tires and distribution or trading market, and offer certain preferential policies, ensure tyre retreading enterprises have abundant source of tire technology advantage, make the most of the use value of waste tires, increase the number of waste tires refurbished and service life. |
