The late introduction of the policy will change the status quo or will change

On May 13, 2010, the 11 national ministries jointly issued the "Opinions on Promoting the Development of Remanufacturing Industries" (hereinafter referred to as "opinions"). The "opinions" proposed that we must accelerate the deepening of pilot projects for the remanufacturing of auto parts in order to promote the remanufacturing of parts such as automobile engines, transmissions, and generators. At the same time, we continue to promote the large-scale renovation of old tires. At the time, Xu Guifen, secretary-general of the China Tyre Renovation and Recycling Association, said: "Associated with the Ministry of Industry and Information Technology, the association is drafting conditions for retreading tires."

On August 20th, 2012, the Ministry of Industry and Information Technology formally released the "Tire Renovation Industry Access Requirements" (hereinafter referred to as "Tire Renovation") and "Entirement Conditions for Waste Tire Comprehensive Utilization Industry" (hereinafter referred to as "Comprehensive Utilization of Waste Tire") respectively. From the aspects of production and operation scale, resource recycling, etc., clear provisions were made for industry access. At the same time, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection will periodically publish a list of companies that meet the two entry conditions. Those that do not meet the access requirements must not engage in tire retreading and tire tire processing and utilization operations.

At this point, the tires have been refurbished and are once again heading for the cusp. Although tire companies have already carried out related work, tire renewal has often been controversial compared to the chaotic market situation. This opinion refers to the continuous promotion of large-scale renovation of old tires. What changes will this bring to the market?

The policy has been delayed for two years to introduce private workshops or will be eliminated

As early as 2010, when the "Opinions" was announced, the China-Singapore Auto Channel had called Xu Guifen. She said: "Refurbished tires are not inferior to new tires in terms of safety and quality. If they are produced in accordance with retreaded tire standards, at least The life of the refurbishment is three times, so as to achieve the purpose of energy conservation and in line with the national industrial adjustment plan. Therefore, retreaded tires will become the mainstream development direction in the future. According to reports, in 2009, China had 13 million retreaded tires, and earlier The long-term plan for retreading tires is to reach 12 million by 2010. As can be seen from the data, the development of domestic retreaded tires has far exceeded the previous industry planning.

Xu Guifen also disclosed that the China Tire Renovation and Recycling Association, commissioned by the Ministry of Industry and Information Technology, is drafting conditions for accessing retreaded tires. At present, the access conditions have been revised several times and reported to the Ministry of Industry and Information Technology. If all goes well, access conditions are likely to be formally introduced by the end of 2010. However, “Tire Renovation” and “Comprehensive Utilization of Waste Tires” were “lagged” until two years after their launch. Can the conditions of access to the two industries solve the chaotic situation in the market of retreaded tires?

According to "Tire Retreading," it is pointed out that the newly-built, rebuilt and expanded tire retreading and processing projects must comply with national industrial policies, and new-build enterprises must have relatively stable old tire supply channels. Tire retreading and processing enterprises have been built, and the annual production capacity of tire retreading shall not be less than 20,000 standard discount bars. The newly-built, rebuilt or expanded tire retreading and processing enterprises shall have an annual comprehensive production capacity of no less than 30,000 standard discount bars. It clearly states that the energy consumption of tire retreading and processing shall be limited to: the total energy consumption of pre-vulcanized retreaded tires shall be less than 15 kWh/standard conversion bar; and the comprehensive energy consumption of moulded retreaded tires shall be less than 18 kWh/standard bar. According to statistics, at present, most of the more than 1,000 tire retreading companies in China are small-scale workshop-type enterprises. Industry experts said that after the implementation of the new industry access policy, it will promote the restructuring of the tire retreading industry, eliminate small workshops and other non-standard.

This also confirms Xu Guifen's statement two years ago that she once said: “After the introduction of access conditions, it will increase the access threshold for the retreading tire industry and standardize this relatively chaotic market. By then, small workshops may be eliminated.”

Market acceptance still needs to train tire refurbishment companies to “eat less”

When it comes to “retrofitting tires”, the majority of end users in the market classify them as “defective products”, which also confirms that domestic car consumers generally fail to form a correct understanding of the use of retreaded tires. It is reported that the United States tire retreading company, each tire can be refurbished at least 3 times, and after each refurbishment can guarantee a million kilometers.

In fact, through the news of the China-Singapore Auto Channel, there are indeed no production problems in terms of technology for retreaded tires. The main obstacles are two aspects: First, the market's ability to accept, and initial promotion is more difficult, and users are not easy to accept. Second, domestic demand for retreaded tires is greater for card and bus users. Domestic truck users are overloaded, resulting in low retreadability of tires. Basically, overloaded tires cannot pass the threshold of retreadable technology inspection.

“The main difficulty in retreading tires is that the scale of industrialization is not large, and the scale of tire retreading plants is too small to keep up. In addition, the source of the tires is also a problem. If a large-scale tire refurbishment factory does not receive a retreadable source, There is also no way. From the details, this may be the biggest problem.” Peng Yonghong, manager of the supporting department of Giti Tire (China) Investment Co., Ltd., said that at present, some domestic manufacturers have acquired tire sources from abroad.

"The current industry is facing a problem, that is, the retreadable source of the shortage of tires, resulting in this reason is mainly due to more tire retreading plants, grab raw materials. Refurbished carcass resources are insufficient, many large-scale enterprises are refurbished Before that, Xu Guifen believed that the import of used tires was not garbage, but a resource. Since tire retreading has been developed so far, technology has matured, not only to minimize pollution, and even to achieve no pollution. In fact, nowadays, Qingdao and Weihai have imported pilot carcass enterprises. In terms of cost, it depends on the company's own channels.

From a rational point of view, at present, domestic tire companies do not seem to consider the issue of remanufacturing in the manufacturing process, causing many old tires to have no remanufacturing requirements. In addition, the traditional concept of the use of tires by domestic auto consumers is accustomed to using tires to the extreme, resulting in waste tires no longer have the value of renovation.

Beam Expander

A beam expander is any optical system designed to increase the diameter of a Laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.

Features

Applications

  • Low power loss

  • Good output collimation

  • Able to withstand laser power of more than 1000 W

  • Adjustable divergence angle of 18 to 32 mrad with the variable beam expanders

  • Precision laser machining: capable to provide a high power density focal spot.

  • Laser range finder: capable to provide a highly collimated beam.

  • Combining with a spatial filter, able to modify laser power distribution.
