U.S.-Egypt Cooperative Research: Evaluation of the Egyptian Calcium Carbonate as a Filler for Application in Plastics, Pigments and Paper Industries

描述：该奖项是为了表彰由美国佛罗里达大学材料科学与工程系教授兼NSF粒子科学与技术工程研究中心(ERC)副主任Hassan El-Hill博士领导的一个美国团队和由埃及开罗中央冶金研究开发研究所(CMRDI)矿物技术教授Tawfik R.Boulos博士领导的一个埃及团队的合作项目。ERC和CMRDI团队计划研究、开发和测试各种制备细粉和泥浆、表面处理技术以及分散埃及石灰石和方解石矿藏中白色填料的方法。还计划对用于塑料、制药、颜料和造纸生产的天然和表面涂层石灰石和方解石填料的粉末和浆液的生产方法进行实验室规模的开发。范围：该奖项将允许埃及和美国科学家之间的合作，他们拥有开展拟议研究所需的互补能力。CMRDI将执行具体任务，包括调查埃及的资源和需求，使用XRF、X射线衍射仪、差热分析进行样品收集和表征，使用筛分、环分仪和激光技术进行粒度分析，以及白度和释放研究，以及实验室规模的选矿研究。ERC将开展新的研磨和分离技术的研究和应用，以及粉末/浆料性能随形态性能和改性剂存在的函数的基础研究。这两个合作团队在研究领域都有很好的资质和经验。这一提议符合INT的目标，即在对双方都有利的领域加强美国与外国的合作。该项目得到了美国-埃及联合基金计划的支持，该计划为两国的科学家和工程师提供资助，以开展这些合作活动。

Description: This award is for support of a cooperative project by a US team headed by Dr. Hassan El-Shall, Professor in the Department of Materials Science and Engineering and Associate Director of Research in the NSF Engineering Research Center (ERC) for Particle Science & Technology at the University of Florida, and an Egyptian team headed by Dr. Tawfik R. Boulos, Professor of Mineral Technology at the Central Metallurgical Research and Development Institute (CMRDI) in Cairo, Egypt. The ERC and CMRDI teams plan to study, develop, and test various methods for preparations of fine powders and slurries, for surface treatment techniques, and for dispersion of white fillers from Egyptian limestone and calcite deposits. Planned also is bench scale development of methodologies for production of both powder and slurry of natural and surface coated limestone and calcite fillers for plastic, pharmaceuticals, pigments and paper production. Scope: This award will allow collaboration between Egyptian and US scientists who have complementary capabilities needed to carry out the proposed research. The CMRDI will carry out specific tasks, including surveys of resources and needs in Egypt, sample collection and characterization, using XRF, XRD, DTA, size analysis using sieving, cyclosizer and laser techniques, and whiteness and liberation studies, and bench scale beneficiation studies. The ERC will carry out studies and applications of new grinding and separation techniques, and fundamental studies of powder/slurry properties as a function of morphological properties and presence of modifiers. The two collaborating teams are well qualified and experienced in the area of the research. This proposal meets the INT objective of increasing US-foreign collaboration in areas that benefit both sides. 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.
