0111248米勒描述:这个奖项是为了支持博士之间的合作项目。犹他州湖城犹他州大学冶金工程系的米勒和埃及开罗赫勒万中央冶金研究与发展研究所矿产资源部的Ahmed Yehia博士。 他们计划在现代表面活性剂脂肪醇乙氧基化物的存在下研究废纸脱墨的基本方面。 这些化合物的吸附在废纸处理涉及的表面上,将在分子尺度上使用软接触原子力显微镜进行研究。 了解废纸组分之间的相互作用力的脂肪醇乙氧基化物的存在下,必要的脱墨技术的进一步改进,将实现胶体探针原子力显微镜研究。 这些结果将与团聚试验,微柱浮选和实验室规模的浮选废纸浆在丹佛型细胞。 此外,还将建立脂肪醇聚氧乙烯醚的分子结构与优化工业脱墨工艺所需条件之间的关系。范围:该项目支持材料加工和漂白领域两个非常活跃的团体之间的合作。 犹他州大学的团队资质良好,拥有项目所需的高科技仪器设备,而埃及团队将使用模型组件和真实的废纸浆进行浮选实验,并分析浮选过程中的纤维亮度、回收率和产量。 Yehia博士也有办法在埃及的工业环境中测试所开发的技术。 研究结果将有助于解决废纸问题。 它可能会对埃及等纸浆资源较少的国家产生更大的经济影响。 该提案符合INT的目标,即支持在共同感兴趣的领域进行合作研究。 该项目得到了美国-埃及联合基金方案的支持,该方案向两国的科学家和工程师提供赠款,以开展这些合作活动。
英文摘要
0111248MillerDescription: This award is to support a collaborative project between Dr. Jan D. Miller, Department of Metallurgical Engineering, University of Utah, Salt Lake City, Utah and Dr. Ahmed Yehia, Mineral Benficiation Department, Central Metallurgical Research and Development Institute, Helwan, Cairo, Egypt. They plan to study the fundamental aspects of wastepaper deinking in the presence of modern surfactants, fatty alcohol ethoxylates. The adsorption of these compounds on the surfaces involved in wastepaper processing will be studied at the molecular scale using soft-contact atomic force microscopy. Understanding of interaction forces between wastepaper components in the presence of fatty alcohol ethoxylates, necessary for further improvement in deinking technology, will be achieved by colloidal probe atomic force microscopy study. These results will be correlated with agglomeration tests, microcolumn flotation and bench-scale flotation of wastepaper pulp in a Denver-type cell. Also the relationship between molecular structure of the fatty alcohol ethoxylates and the conditions necessary for optimization of industrial deinking processes will be established.Scope: The project supports collaboration between two very active groups in the area of materials processing and beneficiation. The University of Utah team is well qualified and has high-tech instrumentation facilities that are needed for the project, while the Egyptian team will conduct flotation experiments using model components and real wastepaper pulp, as well as analysis of fiber brightness, recovery and yield during flotation. Dr. Yehia also has the means to test the developed technology in the industrial setting in Egypt. The results will be helpful in dealing with the problem of wastepaper. It is likely to have more economic impact in countries with few pulp resources such as Egypt. The proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
