Gutta, silver plastic chrysanthemum research and development progress

World natural rubber resources in short supply, today's high prices, increase income and reduce expenditure has become the world's rubber industry is facing the reality of the problem. How to expand the scope of supply of raw rubber, the industry has become a new focus. In addition to the expansion of Hevea brasiliensis in the area of cultivation to increase production per unit area, was re-set our sights on other natural rubber resources development and utilization of traditional medicinal plants and wild Eucommia silver is expected to be rubber-ju in the second and third natural Plastic resources.

China: the development and utilization of Gutta have the absolute advantage

Eucommia is unique to China's precious resources, the country is a secondary plant protection, natural growth in Sichuan, Guizhou, Hunan area, Ke Zhongzhi area accounted for 96% of the world, for a long time in the history of Chinese herbal medicines. In the 1950s, Chinese scientists have used their extraction of natural rubber and found objects from the same old rubber-percha (trans-1, 4 - polyisoprene) the same chemical structure, a very similar performance, it is also known as the ancient Chinese Plastic wave.

Some experts believe that the monopoly of the area suitable for cultivation with their own intellectual property rights together with a complete technology system so that China's development and utilization of Gutta have absolute advantage. Gutta will be applied to the production of tires, not only to comply with international anti-1 ,4-oriented structure rubber, the development of long life, security, energy-saving green tire of the trend, as well as resource-poor China's natural rubber to provide a stable source of adequate The new back-up kind of plastic, and is expected to change the pattern of distribution of the resources of the International Natural Rubber.

In China, to engage in life-long study Gutta Bufaqiren. Chemistry, Chinese Academy of Sciences by Professor Yan Ruifang as early as the 1980s invention abroad and registered a patent for extracting Gutta, and then returned to the successful production of specification 3.25-16 for the Gutta / butadiene rubber motorcycle tires, which Tire wear, thorn-resistant bar, do not tire. In Professor Yan Ruifang led by the Chinese Academy of Sciences chemical researchers found that the rubber vulcanization process Eucommia 3 with different macro-and micro-structure of the stage performance, which developed the role of the 3 categories of different materials - thermoplastic materials, Hot flexible rubber materials and high-elastic material, the "reunification of the rubber material spectrum", and Gutta on research materials to a high degree of engineering theory. At present, Professor Yan has more than 10 patents, an extract from the Gutta to create a variety of rubber products with independent intellectual property rights of the integrity of the technical system has taken shape.

Eucommia leaves, paper, plastic seed-bearing capacity of 1% to 2%, 5% to 8% and 12% to 15%. But the skin and seed production is limited, especially against the felling of trees, Eucommia not have to have skin that only Eucommia leaf is picking a number, a large number of access to resources. However, Eucommia leaf with plastic low volume, high-cost industrial development. In response to this problem, experts at home and abroad, through genetic means to try to cultivate the leaves contain a high amount of plastic Eucommia new varieties, some progress has been made.

Northwest Forestry College of Agriculture and Forestry University of Science and Technology Professor Su Yinquan Eucommia committed to the cultivation of more than 20 years of the new models, components, such as the use of new technologies to explore, in Hunan, Shaanxi, Xinjiang and other places successful application of the "model forest" large-scale cultivation of Eucommia, To ensure that production of Eucommia resources.

Experts believe that the development and utilization of resources Eucommia is the key to the establishment of comprehensive utilization and industrial chain. Eucommia utilization at a high price in China's pharmaceutical, rubber processing, and other materials done a lot of work and achieved initial progress has developed some of the rubber. It is therefore recommended that countries give support to form a production Gutta and applications to open up new resources of natural rubber, rubber to make up for lack of resources and improve the rubber industry cycle of Economy, Trade and Industry chain.

Abroad: silver plastic chrysanthemum possible gradually to replace the natural rubber

Yin-Ju Ge You, also known as the Prince of plastic or rubber Mexico rubber, rubber-ju from the silver extracted from natural rubber. Silver rubber Ju growth in Mexico and the United States, south-west of the northern area of desertification in dry areas can be planted. U.S. companies such as Goodyear in the 1970s had planted a silver rubber-ju, and began processing the application silver plastic chrysanthemum. In the 1980s, with Goodyear rubber trial out of Yinju automobile tires and tire air, and its mileage, the number of takeoffs and landings, and other properties are close to the use of natural rubber.

In addition to the chrysanthemum silver plastic and mechanical properties similar to natural rubber, its largest non-characterized protein. The United States is planning to gradually Synthetic materials and other non-allergenic alternative to natural rubber, plastic silver-ju became the first choice, rubber planting silver-ju was also to the development of local resources and a high degree of natural rubber. United States Department of Agriculture since 2000, will be free to develop allergic reactions natural latex agricultural research institutions in the United States included in the project development plan, and then in September with the Yulex company signed a 5-year, 2,300,000 U.S. dollars funding the project contract. Contracts include: improving the post-harvest processing technology can improve the extraction of latex production; research will be silver chrysanthemum planting rubber into the existing farming systems management; search for more effective breeding, cultivation, plant protection, harvesting, processing, integrated Use of the measures, and examine the above-mentioned factors on the quality of latex.

After years of growing and improved strains, Yulex has been battalion has worked out a set of silver to increase rubber production per unit area Ju way, the capture and extraction of high grade latex technical difficulties. It was founded in 1997, the enterprise has become a United States Department of Agriculture to promote rubber cultivation in silver-ju of the base model. The company achieved in 2003, the first batch of silver-Ju latex products, has in recent years to expand the area under cultivation, there are about 2500 hectares silver rubber-Ju.

A few days ago, Yulex with Centrotrade signed a contract to the next 5 years around the world silver latex Ju distribution rights award given each other. It is estimated that this contract will Centrotrade companies to increase more than 150,000,000 U.S. dollars of annual sales revenue and speed up the silver plastic chrysanthemum industrial applications, the expansion of silver-Ju plastic medical supplies in the dairy products market share. At the same time, Centrotrade company plans to be extended to other areas.
