From December 14 to December 15, Sinopec Corp. held a conference on scientific and technological research on '10 Dragons' held in 2017. Sinopec Corp.'s '10 Long' scientific and technological projects jointly undertaken by Shanghai Petrochemical Research Institute (hereinafter referred to as Shanghai Institute of Chemical Industry) and Shanghai Petrochemical Company 'PAN-based carbon fiber technology development package' through the 'ten dragons' scientific and technological leadership of the leading group for consideration, approved 'out of the dragon'.
At the earlier technical appraisal meeting, the participating experts agreed that the project tackled the industrialization of 1000 kt / a SCF35 carbon fiber industrialized scale and complete set of technology package for oxidized carbonization, and completed the industrialization of 500t / a carbon fiber Device successfully opened 12K carbon fiber small test and test preparation of the whole process, the wet-type test device in tons of wet multi-batch stable system made of kilograms of SCF55 high-performance carbon fiber, with innovative and independent intellectual property rights.
Carbon fiber is a typical representative of new industrial materials in high-tech fields and plays a very important role in upgrading pillar industries in developed countries and improving the overall quality of the national economy. In order to speed up the structural adjustment of acrylic fiber industry, Complete Technology Development "was included in the 2010" Ten Dragons "scientific and technological project, and the layout of DMSO and sodium thiocyanate (NaSCN) two carbon fiber preparation routes at the same time layout.
After seven years of technological breakthroughs, the research team established the rheological rheological model through continuous aqueous precipitation polymerization, rheology of condensed PAN polymer, solidification molding of PAN-NaSCN-H2O ternary system and double chemical reaction in oxidation process And other four aspects of theoretical innovation, the use of self-developed domestic NaSCN solvent route, developed integrated polymerization, liquid, spinning, oxidation carbonization, carbon fiber surface treatment and sizing agents, harmful gases, such as emission control technology standards Eight research and development of innovative technology package.
The SCF55 carbon fiber technology was prepared by the Shanghai Institute of Chemical and Chemical Engineering (SCF55). It broke through the molecular design of copolymerization components, mass transfer and heat transfer of highly viscous fluids, coupling of polymerization monomers, hole control of solidified cross section, solidification and molding of skin core structure, State structure control, the structure-process-property correlation of raw silk and carbon fiber, etc. The basic theory is used to clarify the structure evolution of PAN fibers during polymerization, spinning and oxidative carbonization, and the SCF55 carbon fiber and Fiber quality control indicators in all stages of the establishment of the liquid preparation, spinning, oxidized carbonization graphitization, composite materials innovation four platforms for the China Petrochemical carbon fiber, acrylic, vinylon and other products to provide strong technical support.
