Interfacial Rheology: Fundamental Overview and Applications Overview Interfacial rheology dominates the behavior of many complex fluid systems. Whether the system is characterized by a fluid-fluid interface or fluid-air interface, these characteristics influence the behavior of biological systems, oil recovery, personal care products, food and more. Learn the basic forces that drive interfacial dynamics and…
Designing New Materials for Additive Manufacturing: Vat Photopolymerization Overview 3D printing, or additive manufacturing (AM), provides opportunities to create previously unattainable geometric objects through layer-by-layer fabrication. Novel macromolecular structures and synthetic methods coupled with unique printing methods lead to 3D part generation with micron-scale resolution and tunable to emerging technologies. By tuning polymer structure, printing…
Strategies for Rheological Evaluation of Adhesives Overview Adhesives are widely used in industries and by consumers. A quantitative understanding of the physical performance of such materials, such as adhesiveness, cohesiveness, tack, and peel performance, are important for quality control and for guiding formulators. Rheology is a powerful tool that provides direct measurement of a material’s…
An Introduction To High Pressure Rheology High pressure rheology explores phenomena that are not accessible at ambient laboratory conditions. Three of the advantages of using a pressure rheometer cell include a controlled environment for volatile fluids, saturating fluids with soluble constituents, and exploring new phase space using a combination of temperature and pressure.
Randy H. Ewoldt: Experimental Challenges of Shear Rheology, How to Avoid Bad Data How do you know when to trust your rheology data? How do you avoid bad data? Is there a checklist? Can you co-plot quantitative experimental boundaries against measured data? This presentation will discuss techniques for identifying and minimizing experimental errors and for…
Norman J. Wagner: An Introduction to Colloidal Suspension Rheology Colloidal suspensions are encountered across a broad range of natural phenomena and industrially relevant products and processes. From coatings and inks, to foods and pharmaceuticals, dispersions, sols, gels, and glasses of colloidal particles exhibit a rich rheological behavior. This webinar will present an introductory overview of…
마찰 연구는 유변학을 보완하여 유변학의 벌크 유체 측정에 통찰력을 더하는 고체-고체 상호 반응 정보를 제공합니다. 마찰 연구는 특히 건조 또는 윤활된 조건에서 미끄러지는 속도와 하중의 함수로 마찰 계수의 정량화하는 데 중요합니다. 이를 통해 윤활, 마모, 감촉, 구강 촉감에 대한 유용한 정보를 얻을 수 있습니다.
인장 흐름은 블로 몰딩, 필름 블로잉, 섬유 방사, 열 성형 등을 포함하는 많은 폴리머 공정을 지배합니다. 인장 흐름에서 폴리머 재료의 유변학적 성질은 전단 흐름과 크게 다를 수 있으며 재료 및 공정을 최적화하기 위해서는 이를 이해하는 것이 중요합니다.
