等离子清洗技术对芳纶纤维复合材料的研究

Research of plasma cleaning technology on aramid fiber composites

在某机型的实际生产中处理芳纶纤维时使用了脱模剂。无法有效的清除残留在芳纶纤维上的脱模剂,导致涂装质量不达标。本文分析了等离子清洗对芳纶纤维表面的影响。对等离子清洗后的芳纶纤维进行达因测试和接触角测试,得出了最佳清洗频率、功率和清洗时间等参数。等离子清洗工艺可以有效的去除芳纶纤维表面残留的脱模剂并提高表面活性,增强涂层与基体之间的附着性能,确保了芳纶纤维表面涂装的可靠性。

In the actual production of a certain model,the release agent was used in the treatment of aramid fiber.Unable to effectively remove the release agent remaining on the aramid fiber,resulting in the coating quality not up to standard.The effect of plasma cleaning on the surface of aramid fiber is analyzed in this paper.Dyne test and contact angle test were carried out on the plasma cleaned aramid fiber,and the optimum cleaning frequency,power and cleaning time were obtained.Plasma cleaning process can effectively remove the residual release agent on the surface of aramid fiber,improve the surface activity,enhance the adhesion between the coating and the substrate,and ensure the reliability of aramid fiber surface coating.
