A kind of electro-promoted heterogeneous catalytic recovery device based on CFRP material and its control method

Abstract

A CFRP material-based electrically-promoted heterogeneous catalysis and recovery apparatus and control method therefor. The apparatus comprises an external power supply (100), an electrolytic cell (300) containing an electrolyte (200), and a CFRP sample (400) and a metal sheet (500) each having one end inserted into the electrolyte (200). The electrolyte (200) comprises chloride ions and phosphotungstic acid. The other end of the CFRP sample (400) is connected to the positive electrode of the external power supply (100), and the other end of the metal sheet (500) is connected to the negative electrode of the external power supply (100). The heterogeneous catalysis and recovery apparatus features a simple structure and low costs, and is able to recover carbon fibers with good performance from a CFRP material in a short period of time by optimizing current parameters and the concentration of a catalyst.

Description

technical field [0001] The invention relates to the field of CFRP material recovery, in particular to an electric promotion heterogeneous catalytic recovery device based on CFRP material and a control method thereof. Background technique [0002] Carbon fiber (CF for short) is a microcrystalline graphite fiber material with a carbon content of more than 95%. As an emerging high-performance fiber material, carbon fiber has high tensile strength (2 to 7GPa), high modulus (200 to 700GPa), and low density (1.5 to 2.0g / cm 2 ), small linear expansion coefficient, electrical conductivity and excellent electromagnetic shielding, etc., as well as chemical advantages of resistance to acid, alkali and organic solvent corrosion. In addition, carbon fiber has the advantages of softness, strong plasticity, ultra-high temperature resistance, and fatigue resistance, making it unique in the field of new materials. [0003] In order to take advantage of the light weight and high strength of...
