I aramid industrial scale leap to 1000 tons
After one and a half years of continuous fighting, Yantai Spandex Co., Ltd., which is the largest high-performance fiber production base in China with an annual output of 1,000 tons of para-aramid industrialization projects, has been successfully put into production and has been operating for two weeks. On June 15, industrialized products were formally launched. The first batch of 500-kilogram 3000D para-aramid filaments was sent to the Zhejiang market. This indicates that the domestic production of aramid fiber in China has taken a big step forward. The 1000 tons/year para-aramid industrialization project is Yantai Spandex Co., Ltd.'s initial public offering of equity raised capital investment projects. The project started construction in October 2009. The main project was completed by the end of 2010 and the equipment installation was completed in early 2011. Since March 2011, public works, solvent recovery, sewage treatment and other processes have been successively started. On May 30th, the first para-aramid fiber roll was successfully produced, and the entire industrialization project was successfully tested. At present, the para-aramid production line is operating normally. After testing, the product performance indicators are significantly better than the pilot product. The successful commissioning of the 1,000-ton para-aramid industrialization project made Yantai Spandex Co., Ltd. the only high-tech chemical fiber enterprise in China capable of large-scale production of meta-aramid and para-aramid products, and became the largest in China. The aramid fiber industrial base plays an important role in stimulating the development of China's national industry by meeting the urgent needs of high-performance fiber materials in China's science and technology, security, transportation, and communications sectors. Para-aramid is a high-tech fiber material with high strength, high modulus, flame-retardant, high-temperature resistance, electrical insulation and other characteristics. It is also known as the world's three high-performance fiber materials, carbon fiber, and high-strength and high-modulus polyethylene fiber. fiber. The United States and Japan basically monopolized the global market for para-aramid. Due to its special use in military and science and technology fields, Para-Aramid fiber has always been listed as an important strategic material, production technology is strictly sealed, and trade is strictly controlled. China has invested a lot of manpower and material resources in the research and development of aramid technology since the 1970s, but the key engineering technology has not been a breakthrough. The demand for domestic para-aramid fibers depends entirely on imports, and is severely restricted by people. The long-term shortage of para-aramid supply has, to a large extent, constrained technological progress and industrial upgrading in related fields in China. In 2004, Yantai Spandex launched pilot-scale technology research on para-aramid filaments and pulp. In 2007, it established a 100-ton pilot line, which broke through the core technology of para-aramid and formed independent intellectual property rights. In 2008, the company launched a 1000 ton/year para-aramid engineering project, which received strong support from the national "863" plan and the high-performance fiber composite special project.
