Polarographic characteristics of Te(Ⅳ)-alkaline dye were investiga- ted at mercury electrode in acidic solution.It was found that the mechanism of the electrode process depended on the concentration of Te(Ⅳ).
为解决玄武岩纤维难以着色的问题,先以自制水性聚氨酯阳离子改性剂对玄武岩织物进行改性,而后采用酸性染料对其进行染色,并优化了染色工艺。结果表明,经阳离子改性剂处理后,玄武岩织物的染色性能及力学性能得到了显著提升。Lanaset Red...为解决玄武岩纤维难以着色的问题,先以自制水性聚氨酯阳离子改性剂对玄武岩织物进行改性,而后采用酸性染料对其进行染色,并优化了染色工艺。结果表明,经阳离子改性剂处理后,玄武岩织物的染色性能及力学性能得到了显著提升。Lanaset Red 2B酸性染料对改性玄武岩织物的最优染色工艺为染液pH=5,染色温度70℃,保温时间40 min。该方法染色的玄武岩织物得色较深,强力损伤较小,耐摩擦、耐皂洗和耐日晒色牢度优良。展开更多
