Dry Spinning Of Polyimides Has Reached The International Advanced Level.

In October 26th, the project appraisal of "dry spinning polyimide fiber engineering key technology and complete equipment research and development" undertaken by Donghua University and Jiangsu Olympiad new materials Co., Ltd. was held in Lianyungang, Jiangsu.

The expert group, composed of academician Sun Jinliang and academician Jiang Shicheng, listened to the report of the project completion unit, inspected the production site and reviewed related materials. After questioning and discussing, the group agreed that the project has reached the international advanced level, and some key technologies are in the leading international level. It is suggested that we should further develop the market and accelerate the popularization and application.

The expert group believes that the project has broken the current situation that only a few developed countries such as Russia and Austria have mastered the production technology of polyimide fiber, shortening the gap between advanced countries such as Europe and the United States.

The project has formed many innovative points, such as the synthesis of high homogeneous polymer spinning solution, the new mechanism of fiber dry forming, the regulation of cyclization degree, the stability of precursor fiber, and the cyclization drafting.

The integrated technology, such as polymerizer, spinning channel and components, cyclization and drafting, has been applied in the dry spinning of polyimide fiber.

It is understood that fiber production technology and complete sets of equipment formed a complete independent intellectual property rights, and received more than 20 national patent licensing, is the world's only dry spinning polyimide fiber production line.

Gao Yong, vice president of China Textile Industry Federation, said that during the "11th Five-Year" and "12th Five-Year" period, China has launched a great deal of technical research.

Season.

In the past two years, many scientific research achievements have reached international level, and some even lead the international level. This indicates that China's technology research and development has bid farewell to the stage of mapping and imitation, and has reached a new stage of independent research and development.

It is understood that polyimide fiber is an important high-performance fiber, is currently one of the most high temperature resistant organic fibers, it can be used at 250 to 350 degrees. It is superior to aramid fiber and polyphenylene sulfide fiber in light fastness, water absorption and heat resistance. It is one of the most comprehensive fibers at present, and is an urgent material in aerospace, environmental protection, fire prevention and other fields.

Donghua University and O Shen new materials Co., Ltd.

The dry spinning polyimide fiber project has achieved stable production of polyimide fibers. It has high efficiency, low energy consumption and good quality. It has been successfully applied to high temperature filter media and other fields. It has played an important supporting role in the development of environmental protection, labor protection and special equipment industry in China, and has remarkable economic and social benefits.
