Description
Technical Field
The invention relates to the field of equipment and preparation of recycled carbon fiber recycling and carbon fiber reinforced thermoplastic resin composite materials, in particular to a shaping and quantifying industrialization device for recycled carbon fibers and a using method thereof.
Technical Field
The regeneration technology of the regenerated carbon fiber is focused on the high-efficiency recovery technology of the carbon fiber after the service life of the carbon fiber composite material is ended, and the economic performance and the environmental performance are researched, and aiming at the characteristics of the regenerated carbon fiber, the research report of preparing the novel high-performance blended yarn for the light structure by the recovered carbon fiber is found in foreign countries: the german textile machinery and the high-performance materials technical Institute (ITM) developed a new high-performance blended yarn made from Recycled Carbon Fibers (RCF) that can be used in lightweight load-bearing structures. Jack Howars (J a c k Howardh, University of sheffield) at snow University in England and Joseph sea (Joseph Heil, North Carolina State University, USA) at North Carolina State University in America report the use of regenerated carbon fibers to make electromagnetic shielding materials, introducing the properties of the materials, providing a large amount of data, and opening up a new application field for regenerated carbon fibers. The process for recycling carbon fibers by british gluing technology not only regenerates chopped and ground carbon fibers but also includes other useful substances. Manufacturers and products for preparing carbon paper or carbon felt by adopting the regenerated carbon fibers obtained by the cracking process are available in China. How to produce, process or study information on how to use recycled carbon fibers for their safety hazards in connection with the preparation of reinforced thermoplastic resin Composites (CFRTP) is such as: the technical method and device for how to safely shape and quantify the regenerated carbon fibers in the processes of safe storage, transportation and recycling are not reported.
The regeneration process of the regenerated carbon fiber not only cracks the resin compounded with the regenerated carbon fiber, but also removes the sizing agent protective film of the carbon fiber, so that a huge number of ultramicro grooves (comprising nanoscale holes or cavities) on the surface of the conductive regenerated carbon fiber are exposed outside the conductive regenerated carbon fiber, and the conductive regenerated carbon fiber has extremely strong adhesive and adsorption capacity; in addition, the superfine (monofilament diameter 7um) regenerated carbon fibers subjected to the regeneration process are different in length and in a free-stacking type bundling state without interval protection, so that the superfine regenerated carbon fibers are easy to fly like dust in space. Although the regenerated carbon fiber has excellent performance, the unconstrained extremely strong adhesion and adsorption characteristics and the extremely easy-to-float state cause two main effects:
1) potential safety hazard: during the storage, transportation and post-processing application processes, the scattered regenerated carbon fibers are easy to be inhaled by people and animals or adsorbed by skin and clothes, wherein part of the people and the animals can cause anaphylaxis.
2) The CFRTP field is limited in application: the free-stacking bundling ordered state of the regenerated carbon fibers without interval protection is easily disturbed by external force in the post-processing process, uniform sizing and short cutting of the regenerated carbon fibers are difficult to implement directly, even if the regenerated carbon fibers are sized and short cut, the excessively low and uneven bulk density cannot meet the accurate metering required by re-compounding with thermoplastic resin, and industrial application in the field of carbon fiber reinforced thermoplastic resin Composite (CFRTP) is difficult to realize.
