摘要
对直接耐晒翠蓝GB的老工艺进行了改进,反应温度由原来的132℃降至100℃,稀释温度由5℃提高到20℃,铜酞菁与氯磺酸的重量比由原来的1:8.67降至1:5。氨解后的浆料不经盐折直接进行真空干燥。新工艺生产的产品染色强度高,色光好,含酸废水量减少。
The old technology to produce Direct Ligh Turquoise blue GB (C.I. Direct Blue 86) has been improved. Temperature of the reaction has been lowered from 132℃ to 100℃, the dilution temperature raised from 5℃ to 20 ℃.The weight ratio of copper phthalocyanine and chlorosulfonic acid has been reduced from 1: 8.67 to 1:5. The ammonolyzed product was to be vacuum drying directly instead of salting out. By this new techology, waste acid has been reduced, high quality, high strength and good shade of the product achieved.
