Renovation of the tire: there are worries green industry need to regulate the industry standard

In 2005, China's tire production reached 318,000,000, an increase rate of 32%. The tire raw materials mainly from natural rubber, natural rubber in China mainly relies on imports, in 2005 China's consumption of natural rubber 2,040,000 tons, 490,000 tons produced, only 24 percent meet the demand, and in rubber production, 70 % For the production of tires.

Society of Automotive Engineering of China experts predict that by 2010, only to the automotive industry's demand for rubber will reach 716,000 tons in 2020 may reach 1,630,000 tons. Some industry experts believe that the current trend of development, when our cars meet or exceed the level of the United States, even if the world gave China the use of natural rubber may also be insufficient.

Chinese tire recycling and renovation of the Association of Governing Jiang Yun, China's automobile industry with the rapid development of cars has increased year by year, discarded tires have to double-digit average annual growth rate. Last year, the volume of discarded tires have more than 112,000,000, has become the new solid waste pollution.

How to solve the growing contradiction between supply and demand of rubber resources? How to discarded tires to ease the environmental pressure? These have become our country is facing an important and urgent strategic task. The experts agreed that the economic, environmental protection, recycling use of discarded tires, rubber is to ease the strain on the resources, environmental pollution, waste tire of the most effective way.

Renovation of tires to ease pressure on environmental resources

Discarded tires have to deal with a variety of ways, the simplest way is to use buried on the spot and piling up, this approach not only causes environmental pollution, and will use up a lot of land resources, environment and resources with the pressure of growing distress, such Simple approach has been abandoned by most countries.

At present, discarded tires is the main way to deal with the comprehensive utilization of waste rubber. Rubber used as a renewable resource recycling in China is divided into three major chunk: reclaimed rubber production and utilization; powder production and use; tire renovation. In recent years, reclaimed rubber and rubber powder production significantly increase their use of the use of waste rubber has reached a total volume of 80%, but the tires on the renovation of the market, no significant growth in our tire production in the first approximation of the world Place at the same time, the amount of renovation tire less than 10%.

"Chinese car ownership is less than 30,000,000, but consumed more than 200,000,000 tire." Jiang Zhi Yun said that in the light of our resources, rubber tires and renovation of the increasingly tense situation is too low, Chinese tire recycling and refurbishment of the Association recently issued a call for China Tire urgent need "renovation."

According to experts, 70% of the cost of tires in the matrix, such as motor vehicle tires because of safety reasons, the matrix is much larger than life tread life, but day-to-day running of the tread wear, will have wear and tear and can not use the discarded tires The outer layer, after cutting, pasting on the rubber and then curing, can be used in the renovation to re-birth.

Re-use renovation of old tires is an internationally recognized resource tire recycling the main way that this tire is also a way to use tires of a major reduction measures. Europe, the United States and other developed countries, the use of a tire, well-maintained condition, after sorting overhaul can be refurbished several times, each time the renovation can be equivalent to re-new tire life 60-90% of life through multi - Renovation of times, at least make the total tire life 1-2 times. And a renovation of discarded tires are only equivalent to the consumption of raw materials production with a new tire specifications of 15-30%, the price was only 20-50% of the new tire.

"Last year, members of the Association of internal data is 9,000,000, plus scattered, as well as other enterprises, renovation of the tire is only 11,000,000, compared to 318,000,000 tire production figures, new tires and tire renovation of the ratio of only 29:1 , And a far cry from the developed countries abroad. "Chinese tire recycling and refurbishment of the Association of the Technical Committee Liu, deputy director of the China Economic Times in an interview with reporters, he said.

It is understood that in order to ensure the renovation of the tire recycling, the developed countries require a new tire manufacturer's products can be reused many times the renovation, the European Union over the truck tire replacement tires account for 57% of new cars accounted for 23%, while China Heavy-duty vehicles account for only 4%, 0% more cars. Some developed countries, only the tires can no longer be detected after the renovation, only to scrap tire rubber powder and used in the manufacture of rubber, steel wire or fiber recycling at the same time.

Turn hindered the development of tire industry

"Without the refurbishment of used tires, is worried about security issues, had previously heard that because of tire trouble renovation of the incident." Master driver Zhang told reporters that "to know that the tire renovation, but I do not know what is the specific manufacturers Renovation, there is no guarantee that the quality is also not known, the first to consider the replacement of tires or new tires. "

Zhang and master the same concept of a few people. All along, people tire of the renovation of the erroneous understanding that the renovation of poor quality tires, mileage short, there are potential safety problems and so on.

"This situation over the past fetal technology may be behind the times. But with the rising level of technology, renovation of the quality of the tires on the rise, the renovation of the current tire technology has matured, its safety, durability, mileage, Rubber-saving resources and energy, reduce costs and consumption, and so on can be comparable with the new tires, but also the significance of environmental protection. "Liu told reporters, although today's technology over more mature fetus, but the renovation of the tire industry is still plagued with problems, tires Renovation of small-scale enterprises, market order chaos, poor awareness of the brand, which is in the renovation of Chinese tires have not been approved.

Turning to China's automobile tire industry renovation of the situation, access to the city of Baoji in Shaanxi tire factory renovation Zhang Shaojun call a spade a spade: "Although we are in the works for the Northwest is the largest, but the country is concerned, we plant is the worst capital Shortage of obsolete equipment, backward technology, and rapid development in some coastal areas of Meifa Bi renovation of enterprises. "

But reporters have learned, even in the developed coastal areas, renovation of the tire industry are extremely limited in China's tire plant renovation Although there are hundreds of so-called, but the average child up less than 10,000, and, in addition to Guangdong, Fujian , The main heat or turn-based, advanced pre-curing is still tread very few, very few turned cold.

"Now, a common birth of the new plant will have an annual output of several million, and currently the country's largest tire factory renovation of the renovation capacity less than 200,000, is not a new tire plant to build up the tire plant in Tire output of the country close to first in the world, can not turn a complete set of fetal development. "Liu noted that China's tire industry renovation of the status quo.

It is reported that the world's Big Three tire, "Michelin" and "Goodyear", "Bridgestone", are supporting the establishment of a turn around the factory child, and we will continue to promote the development of new technologies. International's largest tire manufacturer Michelin in Europe and the United States promised to renovate three times a tire can eventually discarded, but most of the Chinese enterprises do not have this commitment, because the Government does not require that people have this lack of awareness.

Need to regulate the industry standard

Now there are two types of tire factory renovation of marketing, called child services, primarily for services in the enterprise, such as public transportation, passenger transport companies, the renovation works directly with the bus company contracts; called the acquisition a second child, is working to send Tire distribution center personnel to the acquisition, the primary matrix After passing the examination, renovation, but tire distribution center closed up tires, scrap rate is very high, not basic renovation.

"The first method to collect the limited number of tires, and the other a collection of methods and exist in a certain degree of risk, our factory was unable to expand the size of the tires subject to a large extent Source." Renovation of a tire factory Director reluctantly told reporters.

Can the use of recycled tires and tires used to use a great relationship. For example, some very good car, the owner of a tire tread wear look, and immediately replaced with new tires, replacement of the fact that it can be a renovation of the tires, but many owners do not, then directly to the discarded tires, there are examples of such However, the number is relatively small. More people are taking "one-child in the end run".

In recognition of the errors, many drivers are often tire of a "bad run", not according to mark the limit for tire wear refurbished for reuse, not only caused by unsafe driving, but also because of the use of excessive tire and lost the value of the renovation; some people to buy Figure tire when cheap, low quality, choice of tires, the tire manufacturer and the level of life expectancy is relatively low, and even on a cycle entirely, so the tires can not be natural renovation; some of the production of tires defective tire plant, some illegal Elements to the market, after simple treatment for the sale of these problems if the tire renovation, there are bound to a greater security risk.

In addition, there is a part of the problem is due to overloading caused by overload of the tire, the tire internal structure of a more serious injury, even though from the outside looks very good, but it has been fatigue, which in some cases with special laser detection equipment And X ray irradiation have to disagree.

Liu pointed out that the refurbishment of some of the tires from the tire on the existence and the source of quality problems, such as overloaded tires, tires formal renovation works are refusing to recovery. However, as Chinese tire industry, renovation of the current situation is "small" and "casual" does not rule out a number of informal manufacturers of renovation, the renovation of tire easily after the accident, which has generally been the responsibility of the formal count of over Plant fetal head.

As a result, Chinese tire recycling and refurbishment of the Association suggested that China should be introduced as soon as possible "waste tire recycling regulations" to promote renovation of old tires and used tire rubber powder technology, equipment and the development of the market. Once started all over the recycling of discarded tires into the urban construction planning, the establishment of a standardized recycling system, China has also renovated the tires will formally start.
