In mid-September 2021, the 10,000-ton carbon fiber production base invested by JSZF Carbon Fiber Technology Corporation officially began commercial production.
This project is the largest carbon fiber production base in China. The total investment of the project is 5 billion yuan. The first batch of carbon fiber products can reach China's leading T700 and T800 levels, and can be applied to pressure vessels, photovoltaics and other industrial fields.
The new carbon fiber production line adopts dry jet wet spinning technology, has complete independent intellectual property rights, and the localization rate of equipment is as high as 85%. After being put into production, it can greatly enhance the independent and controllable ability of China's carbon fiber supply chain.
Carbon fiber is a capital and technology-intensive industry. Asset investment and technology research and development have become important ways and high barriers for industry companies to upgrade and advance. From the perspective of the global market, the industry has long been monopolized by companies such as TORAY and HEXCEL, including dry jet wet spinning and high-end carbon fiber products. Half of the Chinese market needs to rely on imports.
Due to the difficulty of the dry jet wet spinning process, most of the carbon fiber manufacturing enterprises in China still use the wet spinning process.
In 2008, the company took the lead in breaking through the industrialized manufacturing technology of dry-jet wet spinning of 1,000-ton carbon fiber precursor and built China's first industrialized production line of 1,000-ton dry-jet wet spinning carbon fiber.
Over the years through independent research and development of core technology precipitation, the company has now formed "large-capacity polymerization and homogenization stock solution preparation technology", "high-strength/medium model carbon fiber precursor dry jet wet spinning key technology", "PAN fiber rapid homogenization The four core technology systems of "pre-oxidation and carbonization integrated technology", "dry-jet wet spinning thousand-ton high-strength/100-ton medium-mode carbon fiber industrial production system construction technology".
At present, the company has obtained 53 authorized patents, including 25 invention patents. As the main drafting unit, it participated in the formulation of the national standard of "Polyacrylonitrile-based carbon fiber" twice, and participated in the industry standard of "Polyacrylonitrile-based carbon fiber precursor" once. Formulate.
JSZF's product models have basically achieved the benchmarking of the main carbon fiber product models of Toray Japan, the industry leader, and achieved the coverage of high-strength type, high-strength medium model, high-strength high model and other categories of carbon fiber.
The company currently produces dry-jet wet-spun carbon fiber on all production lines, and the product quality is comparable to similar international products. With the improvement of product quality and the increasing demand in the domestic and international carbon fiber markets, the average unit price of the company's carbon fiber products has been increasing year by year.
The company`s main export products cover high-strength, high-strength medium models, high-strength high models and other categories, mainly used in aerospace, wind power blades, sports and leisure, pressure vessels, carbon/carbon composite materials, transportation construction and other fields.
JSZF has a mature dry-jet wet spinning industrialization technology system, and has mastered carbon fiber T300, T700, T800, M30, M35 thousand-ton technology and M40, T1000 and T1100 large-scale production technology, and has become domestically produced One of the main forces of carbon fiber.
At present, China's carbon fiber industry is in a stage of rapid expansion. Facing the rapidly growing market demand in wind power blades, carbon-based composite materials, pressure vessels and other fields, many carbon fiber companies in China are willing to expand their production capacity and have entered a new round of capacity building boom.
