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

说明：该奖项是为了支持由佛罗里达大学材料科学与工程系教授兼美国国家科学基金会工程研究中心（ERC）颗粒科学与技术研究副主任Hassan El-Shall博士领导的美国团队和由埃及开罗中央冶金研究与发展研究所（CMRDI）矿物技术教授Tawfik R. Boulos博士领导的埃及团队开展的合作项目。ERC和CMRDI团队计划研究、开发和测试各种方法，用于制备细粉末和浆料，用于表面处理技术，以及用于从埃及石灰岩和方解石沉积物中分散白色填料。此外，还计划开发用于塑料、药品、颜料和纸张生产的天然和表面涂层石灰石和方解石填料的粉末和浆料的生产方法。范围：该奖项将允许埃及和美国科学家之间的合作，他们具有开展拟议研究所需的互补能力。CMRDI将执行具体的任务，包括调查埃及的资源和需求，样品收集和表征，使用XRF、XRD、差热分析，使用筛分、环筛机和激光技术进行粒度分析，以及白度和解放研究，以及实验规模的选矿研究。ERC将进行新的研磨和分离技术的研究和应用，以及粉末/浆料特性作为形态特性和改性剂存在的功能的基础研究。这两个合作团队在研究领域都很有资格和经验。该提案符合INT的目标，即在有利于双方的领域增加美国与外国的合作。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，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.
