China is a country with relatively scarce rubber resources. Nearly 80% of rubber raw materials need to be imported every year. However, there are more piles of waste rubber tires on the market, and the number is much more difficult to digest, resulting in a huge "black pollution." In order to make up for the shortage of rubber resources in our country and solve the difficult status of waste tire processing, China began to develop the reclaimed rubber industry.
According to the status of China's rubber resources, the reality of replacing 1 ton of natural rubber with 3 tons of reclaimed rubber will continue. Since the founding of New China, the waste rubber recycling industry has used more than 16 million tons of waste rubber to accumulate more than 30 billion yuan of output value for the society, saving more than 5 million tons of rubber. It should be said that reclaimed rubber and vulcanized rubber powder have played an important role in solving the "black pollution" and developing the recycling economy of the rubber industry. Tire reclaimed rubber is the most widely used reclaimed rubber in reclaimed rubber products. It plays a major role in relieving the lack of rubber resources in China and the great polarization of rubber.
However, in recent years, there have been popular sayings that “the tire reclaimed rubber is the sunset industry, and the vulcanized rubber powder is the sunrise industry”. Later, “there is secondary pollution from the reclaimed rubber production, which has been eliminated by the developed countries.” Reports continue to be reported to the press, and as a basis for this, the comprehensive utilization of waste rubber in China is still a manifestation of the backwardness of reclaimed rubber. It is proposed that the state should limit the development of reclaimed rubber. In fact, these views and reports do not meet the status quo of comprehensive utilization of waste rubber in China.
First, developed countries do not produce reclaimed rubber because they cannot solve the secondary pollution. In 1991, when the domestic waste rubber industry went to Europe to inspect the technology, the German WMG Group made it clear on the situation and development trend of the European reclaimed rubber production: Because the price of reclaimed rubber in Europe is almost the same as raw rubber, there are few sales, so in addition to a few Outside the company, the rest of the manufacturers have stopped production. The recession of reclaimed rubber production in Europe forced European waste rubber to turn to fuel incineration and crush the processing of vulcanized rubber powder to produce rubber blocks and plastic sheets. It can be seen that developed countries do not produce reclaimed rubber, not because of its pollution and technological backwardness, but because of the market and the price. In addition to this, another important factor is that developed countries have eliminated nylon tires, the main raw material for the production of tire reclaimed rubber, and instead produced and used wire radial tires.
Tire reclaimed rubber is still the main way to solve the waste tire pollution in China, accounting for 90% of the total use of the country's waste tires; the application of vulcanized rubber powder is still under development. With the rapid increase in the radialization rate of tires in China, there will be less and less waste tires, which will force the reclaimed rubber production to shrink. By then, the production of low-cost vulcanized rubber powder will become the main way to comprehensive utilization of waste rubber.
In fact, from the perspective of the role of tire reclaimed rubber, it is one of the main raw materials for the rubber industry, not only has good process performance, but also has good physical and mechanical properties, can be well integrated with various rubber, so it can be based on rubber hydrocarbons The content and other performance indicators replace some natural rubber or synthetic rubber production rubber products, can be applied in many areas of rubber products, that is, saving rubber raw materials, but also can reduce the cost of raw materials, but also solve the problem of waste tires difficult to handle. It is a good way to solve the problem whether it is a country or a rubber product manufacturer.
With the progress of society, new reclaimed rubber production equipment and desulfurization technology are in the research and development stage. The backward traditional technology will be gradually eliminated. The production of tire reclaimed rubber is proceeding toward energy conservation and environmental protection. Therefore, the production of tire reclaimed rubber will not be ended due to environmental problems, but will go further and further as the market expands. Tire reclaimed rubber will also be continuously improved along with the progress of the production process, and the scope of use will be wider and wider.
Hebei Hongyun Reclaimed Rubber Factory is committed to the development and production of a variety of reclaimed rubber. The selection of tire reclaimed rubber 900-1200 imported Bridgestone, Michelin tires and different types of domestic waste tires, after strict classification, cleaning, production The tire reclaimed rubber products have a high strength and a small specific gravity, and can be used as substitutes for different rubber raw materials to produce products, thereby significantly reducing the cost of raw materials.
