摘要
采用针刺无纬布预制体,沥青浸渍-炭化和树脂浸渍-炭化相结合的致密工艺,并经过高温处理后制得制氟用炭/炭复合材料电解板。进行了力学、电阻率、热学性能检测;同时,经过了在电解槽中的上槽运行实验。研究表明:炭/炭复合材料电解板与炭电解板相比具有很高的力学性能,其拉伸强度、弯曲强度、压缩强度都有很大的突破,在电解槽中具有很强的抗腐蚀能力,并且具有良好的热学性能和较低的电阻率,延长了电解板在电解槽中的使用寿命,减少了电解板的更换率。同时,利用扫描电镜对断口进行微观结构的观察分析,表明拉伸断口为脆性断裂。
The C/C composites electrolysis plank that applied to preparing fluorine we produced by carbon fiber perform, pitch infuse and carbonization, resin infuse and carbonization and high temperature treatment processing. Then it was analyzed by mechanics performance, electrical resistivity, thermal performance. At the same time, the C/C composites electrolysis plank was tested in electrobath. The results showed that C/C composites electrolysis plank had high mechanics performance, having perfect tensile strength, compressive strength , flexural strength and shear strength, having excellent anti-corruption, thermal performance and electrical resistivity. It extended life of electrolysis plank and reduced replacing in electrobath. The microstructure was analyzed by SEM. The experiment showed that fracture part was fragile fracture.
