Para-aramid is the abbreviation of para-aramid fiber. It is one of the organic fibers with the best comprehensive performance among the mass-produced fibers. The trade name of the American DuPont company is Kevlar, the trade name of the Japanese Teijin company is Twaron, and the name of China Aramid 1414 or Aramid II is now widely used in various aspects of the national economy such as military, aerospace, electromechanical, construction, automotive, and sporting goods.
Aramid fiber was first developed by DuPont in the United States and began industrial production in 1971. However, in the past few decades, only a few companies in the United States, Japan, South Korea and Russia have the production technology of para-aramid fiber, so that whether para-aramid fiber can be produced has become a country to some extent. One of the symbols of strength. It is precisely because of its unique role in aerospace and defense that foreign countries have long imposed a technical blockade on China, which has restricted China's application and development in related fields.
China has launched technical research on aramid very early, and China has included para-aramid in the National 863 Program many times. As the earliest batch of aramid fiber challengers, ZHLX has started research on para-aramid fiber since 1990, and finally ushered in a historic breakthrough in 2005-2007, successfully building a 50-ton / year In the continuous operation of the para-aramid pilot line, the product performance index has reached the domestic leading level.
In 2008, in order to better promote the industrial development of aramid, ZHLX Chemical Research and Design Institute Co., Ltd. industrialized scientific research results and established a wholly-owned subsidiary CDLX New Materials Co., Ltd. Invest in the construction of "ZHLX New Material Base". In 2009, the first production line with an annual output of 1,000 tons in China with independent intellectual property rights was built, and in 2014, continuous and stable production of aramid has been achieved. The industrial production of para-aramid is not so much due to the successful maturity of the technology, but rather the maturity of the technology application conditions. This also makes ZHLX one of the few high-tech chemical fiber enterprises in China that can produce para-aramid products on a large scale. In three years, ZHLX has achieved a historic leap from China's aramid from laboratories to industrialization, ending the monopoly of this industry in developed countries such as the US and Japan for about 40 years.
The huge market space also promotes the rapid development of domestic aramid. China's demand for para-aramid is about 12,000 tons, China local supply accounts for less than 1/4, and the rest comes from imports. In 2020, China's aramid fiber market will reach about 14.4 billion yuan, with a compound growth rate of about 20%. This shows that the production of domestic para-aramid is far less than the market demand, and there is still much room for development.
The optical fiber and cable industry is developing rapidly, and the construction of 5G brings imagination to the demand of aramid. Para-aramid fiber can increase the rigidity and strength of the optical cable, and is widely used in indoor and outdoor optical fiber and power cable reinforcements. It plays an important role in promoting the development of China's new generation of communication technology. Experts predict that the demand for para-aramid for optical cables will reach 5,050 tons in 2019, and will reach a higher level of 5,400 tons in 2020. With the construction and upgrading of 5G networks in the future, the usage of para-aramid in the field of information and communication will further increase.
