中文摘要 | 生產色紙之紙廠,對於廢水排放標準日益嚴格之今日,減少廢水污的方法之一為有效地利用如Sulfur Red 12、Sulfur Yellow 9及Sulfur Blue 13等硫化染料,因其有著極佳之光堅牢度及良好纖維親合力,頗適於紙廠染色之用。最大溶解度於攪拌1小時及硫化染料/硫化鈉之混合比以1/1時(重量比)為佳。由1%硫化染料硫化鈉溶夜之UV光譜圖可知最大吸收度之波長受不同硬化鈉溶液濃度之影響有顯著移動現象。 |
英文摘要 | As the impact of the abatement of water pollution for colored papermaker, the application of sulfur dyes i.e., Sulfur Red 12, Sulfur Yellow 9 and Sulfur Blue 13 with their superior lightfastness and strong affinity to pulp fibers might interest paper mill. However, when using sulfur dyestuffs, the disadvantages are that not soluble in water. Usually, sodium sulfide are available for dissolving sulfur dyes. Upon sulfur dyes' dissolving test, one hour mixing time and the mixture ratio of 1 (sulfur dye) to 1 (sodium sulfide, by weight) showed the maximum solubility. The UV Spectrum of 1% sulfur dyes' Na 2S solution indicated that the wavelength shift of maximum absorbance was evidently affected by series concentrations of Na_2S applied. |
