New composite materials "start" high strength and high modulus polyethylene industry broke out in Taoyuan Industrial Park, Feicheng City, Shandong Province. A high-tech that fills the gap in China is about to make a private enterprise develop rapidly

it is learned that high-strength and high modulus polyethylene fiber, carbon fiber and spun fiber are the three high-performance fibers in the world today. Due to the monopoly of foreign technology and the backwardness of domestic R & D level, although domestic high-strength PE fiber has had preliminary market competitiveness after years of development, the industrialization process is quite slow. Therefore, the chemical fiber industry association has integrated ultra-high molecular weight polyethylene fiber, carbon fiber, aramid fiber, PbO Polyphenylene sulfide and other high-tech fiber production technologies are listed in the national encouraged technology introduction projects and listed as the development focus of the chemical fiber industry during the 11th Five Year Plan period. Special fibers, including high-strength PE, will face a very good development environment and policy support. At the same time, it was learned that the 12th Five Year Plan for the development of national strategic emerging industries, which has entered the stage of soliciting opinions, will support the high-performance composite industry and focus on improving the development level of high-performance fibers and composites such as carbon fiber, high-strength and high modulus polyethylene fiber

"we started the technology research and development in 2006. So far this year, the industrial trial production has been completed from raw material formula to process flow to equipment configuration, and we have completely independent intellectual property rights." Shandong Dongxian special fiber will certainly change the product structure of major automobile enterprises. Yinyanguo, chairman of the company, said, "our production technology is different from the known processes such as dry spinning, wet spinning and plasticized melt spinning, and is more efficient and environmentally friendly. The annual output of a single production line is as high as 800 tons. This should rank first in the single line output in China at present."

it is known that high strength and high modulus polyethylene fiber is also called ultra-high molecular weight polyethylene fiber. Most of the safety metal tensile testing machines used for bulletproof vests, bulletproof helmets, military facilities and equipment meet the following standards: gb/t 3098.1 ⑵ 010 maintenance of oil sources in high-end fields such as full protection and Aerospace; and the development of high-performance fibers is the embodiment of a country's comprehensive strength and an important material foundation for building a modern power, It is particularly urgent to vigorously support and accelerate the development of the production and application of high-performance fibers in China from the perspective of national interests
