The production device breaks through blockade on techniques of developed countries, and localization is achieved totally.

Description

technical field [0001] The invention relates to the field of carbon fiber production, in particular to a polyacrylonitrile-based carbon fiber production device and a production method thereof. Background technique [0002] As the third-generation engineering material of human beings, carbon fiber not only has extensive social benefits, but also has objective economic benefits. Its appearance will bring a new revolution to human industry and form a new industrial system. Due to the characteristics and functionality of carbon fiber, it has been nearly half a century since it will become a necessary material for life and an important strategic material for the development of human science and technology. From the current point of view, it still takes a few years to work hard, and there must be a strong economy. Strength and effective policy support, and it needs to gather a team of experts with considerable theoretical and practical experience at home and abroad to jointly res...
