酸碱处理条件下芳纶Ⅲ的强伸性能研究
Strength & Elongation Study of Aramid III Fiber in Acid & Alkali Treatment Condition
摘要
Abstract
The change situation for the strength &elongation of domestic aramid III fiber under acid &alkali condition was discussed.The strength & elongation properties of original domestic aramid III fiber and treated under acid & alkali were tested and analyzed.Moreover,they were compared with para-aramid.The test results show that the breaking strength of aramid III fiber is almost 1 .5 times that of para-aramid,the modulus is higher than that of para-aramid.Under the treatment of strong acid solution,hydrolysis phenomenon was happened on the amido bond of macromolecular structure.However,it still shows better acid resistance.Under the treatment of strong alkali solution,domestic aramid III fiber still has excellent alkali resisting property.It is considered that domestic aramid III fiber is suitable for the situation with requirement of higher strength and higher modulus and a certain requirement on acid resistance and alkali resistance.It is a better filtration material.关键词
