Ultrasonic atomized steam assisted double-roller carbon fiber drying and heating device

Abstract

The invention relates to an ultrasonic atomized steam assisted double-roller carbon fiber drying and heating device, and belongs to the technical field of drying device preparation. According to the device, a steam composite surface drying method is adopted, water is heated to form steam, then ultrasonic oscillation is performed so as to form small steam droplets and form a stable and uniform disperse system and disperse into a material drying device, the phenomena of nonuniformity and difficulty in control over the temperature of roller surfaces of the drying device in a traditional techniqueare effectively improved, the temperature and humidity of an environment field are stable and controllable, the runaway speed of water molecules in raw silk is effectively controlled by adjusting thehumidity, the phenomenon of a skin-core structure of a material is reduced, the phenomenon of brittle failure of the carbon fiber material in a preoxidation process due to the skin-core structure iseffectively improved, and oscillation dispersion is performed on the material by the ultrasonic device, so that the steam is effectively and uniformly scattered and is dispersed, and the drying efficiency and the uniform performance of the drying device are further improved.

Description

technical field [0001] The invention relates to a double-roller carbon fiber drying and heating device assisted by ultrasonic atomization steam, which belongs to the technical field of drying device preparation. Background technique [0002] Carbon fiber is generally an inorganic non-metallic material with a carbon content of more than 95% obtained by high-temperature carbonization and graphitization with polyacrylonitrile as the precursor. It has a series of excellent characteristics such as low density and high strength, so resin-based composite materials using it as a reinforcement have a wide range of applications. The interfacial properties of carbon fiber resin matrix composites depend on the surface structure and characteristics of carbon fibers, such as surface functional groups, surface roughness, surface energy and specific surface area, etc. However, carbon fiber belongs to the structure of turbostratic graphite, which is relatively ordered in two dimensions and ...
