GQ45 High Performance Carbon Fiber Engineering Technology And Equipment Were Approved.

< p > China Textile Industry Federation organized the appraisal of technical achievements of "dry spray wet spinning high performance carbon fiber engineering key technology and equipment research and development" undertaken by Zhongfu Shen Ying Carbon Fiber Co., Ltd., Lianyungang Eagle travel Textile Machinery Co., Ltd., China Composite Material Group Co., Ltd. and Jiangsu Lianyungang Shen Shen Refco Group Ltd in < a href= "//www.sjfzxm.com/pioneer/" > Jiangsu < /a > province.

< /p >

< p > by the expert group of the Chinese Academy of Engineering academician Sun Jinliang and Jiang Shicheng as the deputy director of the appraisal committee, the expert opinion group held that: "dry jet wet spinning GQ45 high performance carbon fiber engineering key technology and equipment development" project has pioneered the breakthrough of the international advanced dry jet wet spinning carbon fiber manufacturing technology, and developed a homogeneous polymerization system suitable for dry spray wet spinning, a low disturbance air level fiber forming system and a high-speed high power steam drafting system.

In terms of equipment, the project has independently developed and designed a fully mixed 60 cubic meter polymerizer, dry spray wet spinning fiber forming equipment, steam drafting equipment, a complete set of carbonization key equipment, and efficient solvent recovery and waste gas treatment system.

Based on the above key technology and equipment foundation, carbon fiber products with various indexes all up to the national standard GQ4522 have been prepared and applied to many manufacturing enterprises, < a href= "//www.sjfzxm.com/news/index_c.asp" > composite material < /a >, reflecting well.

The identification committee agreed that SYT45 (GQ45 grade) products reached the leading level in China and the advanced level of similar products in the world.

< /p >

< p > it is understood that Zhongfu divine eagle Carbon Fiber Co., Ltd. has a complete set of independently developed international mainstream technology, dry spray wet spinning SYT45 (grade GQ45), which is equivalent to T700 grade high performance carbon fiber precursor production line and carbonization production line. Zhongfu divine eagle has become the only enterprise in China and the world's third difficult tackling technology for dry spray wet spinning process.

< /p >

< p > after 4 years of research and development, the company first broke the dry spray wet spinning process with less than a href= "//www.sjfzxm.com/news/index_c.asp" and high performance carbon fiber < /a >.

< /p >

< p > SYT45 (GQ45 grade) high performance carbon fiber has tensile strength up to 4.5GPa and modulus up to 240GPa. It is widely used in industrial, civil engineering, medical equipment, sporting goods, military and aerospace fields.

The development of high performance carbon fiber SYT45 (GQ45) is not only the needs of modern national defense, but also the needs of national social and economic development.

< /p >

Compared with wet spinning, dry jet wet spinning can be used to stretch the spinneret with high spinneret and high spinning speed. Dry jet wet spinning can form a dense thin layer in the air layer to prevent the formation of large pores, which is better than that of wet spinning. < p > dry spinning wet spinning.

The fibers obtained by dry jet wet spinning process are relatively uniform in structure, small in core layer, high in strength and elasticity, nearly round in section structure, smooth in fiber surface, and few in fiber defects.

The fibers with high density and high bulk density can produce high performance carbon fibers, which are superior to those of wet spinning carbon fiber in the field of carbon fiber composites.
