摘要
通过对普通腈纶进行特殊预处理和改性,制备出一种具有良好抗浓酸侵蚀性的反应性高分子纤维材料,对改性纤维材料的化学(酸)稳定性、力学性能、微结构等特征性能研究表明:该纤维材料在120℃和98/浓硫酸环境条件下,经过20min的侵蚀性处理后,其材料仍能够保持一定的力学性能和微结构,显示了突出的抗浓硫酸侵蚀性。
The new type of reactive polymer fiber, RPF-AA, was prepared by the processes of pre-treatment, modification of the commercial nitrilon fiber, and the chemical stability in the strong sulfuric acid. Mechanical properties and micro-structure of the RPF-AA were investigated. The obtained results show that the RPF-AA presents very good mechanical properties and micro-structure after sucked in 98 % sulfuric acid for 20 minutes under 120℃. It is indicated that the FPF-AA has a good stability in the circumstance of strong sulfuric acid solution.
