Waterborne Polyurethane Coatings with Covalently Linked Black Dye Sudan Black B
Colored waterborne polyurethanes have been widely used in paintings, leathers, textiles, and coatings. Here, a series of black waterborne polyurethanes (WPUs) with different ratios of black dye, Sudan Black B (SDB), were prepared by step-growth polymerization. WPU emulsions as obtained exhibit low particle sizes and remarkable storage stability at the same time. At different dye loadings, essen...
متن کامل:بررسی اثر الکترواپتیکی کر با استفاده از کریستال مایع نماتیک (sudan black b )
در این نوشتار، رفتار غیرخطی نوری بلورهای مایع نماتیک به صورت خالص و آلاییده به رنگینه آزو بررسی شده است. روش روبش- z برای اندازه گیری ضریب شکست و ضریب جذب غیرخطی بلور مایع نماتیک 6chbt در دوحالت خالص و آلاییده به رنگینه sudan black b بکارگرفته شده است. اندازه گیری ها تحت تابش لیزر he:ne با طول موج 8/632 نانومتر و بیشینه توان خروجی 50 میلی وات در حضور میدان الکتریکی خارجی ac صورت گرفته است. نتا...
15 صفحه اولAdsorption of Remazol Black B Dye from Aqueous Solution Using Bagasse
The dye of wastewater is a major environmental problem. Chemical and biological treatment of wastewaters containing dye is difficult due to the low level of adsorption and chemical stability of dyes. Activated carbon is usually used for adsorption of these materials, but because of high prices and restore problems, researchers trying to find available, low-cost materials with high adsorption. I...

Contact: Dr. Charles F. Palmer Ethox Chemicals [email protected] T +1 864 277 1620 They are used in many industrial and architectural applications. The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...
متن کاملDetermination of serum lipo-proteins by paper electrophoresis after preliminary staining with Sudan black-B.
UR PRESENT KNOWLEDGE of human serum lipoproteins and their significance in atherosclerosis may be attributed to the development of suitable methods (1, 4, 6, 8, 9, 13, 15) and to extensive studies of human subjects (2, 5, 10, 11, 16, 18) by such methods. The ultracentrifugal, the chemical, or the free electrophoretic methods are technically difficult for routine determinations of serum lipoprot...
