摘要：通过优选分散剂的方式改善碳纤维纸的匀度,制备出温度分布均匀的碳纤维纸,探讨了分散剂对碳纤维纸匀度性能的影响,以及碳纤维纸电阻对电热性能的影响。采用尘埃匀度仪、热成像仪等仪器对制备的碳纤维纸进行表征。结果表明,制备碳纤维纸时,加入用量0. 6%的阴离子聚丙烯酰胺(APAM)能够较明显地改善纸张匀度;碳纤维纸在通电加热条件下,电阻仅降低了2. 59%,纸张表面温差小于6℃,具有恒定功率的特征;碳纤维在纸张中的加入量为5. 0%左右,可以获得较高的远红外法向全发射率,在8～15μm波段纸张法向全发射率最高为83. 13%。
Carbon fiber paper with uniform temperature distribution was prepared by optimizing dispersant to improve the uniformity of carbon fiber paper.The influence of dispersant on the uniformity of carbon fiber paper and the influence of resistance value of carbon fiber paper on electric heating performance were discussed.The prepared carbon fiber paper was characterized by using instruments such as dust homogenizer and a thermal imager.The results showed that adding 0.6%APMP,the uniformity of the carbon fiber paper could be improved significantly,under electric heating,the resistance value of the carbon fiber paper only reduced by 2.59%,and the temperature difference on the paper surface was less than 6℃,which had the characteristic of constant power,was more appropriate to control a lower content of carbon fiber in the paper in order to have a higher normal emissivity of far infrared.In this study,when the content of carbon fiber was 5.0%,the far infrared emissivity in the 8~15μm band was 83.13%.
