中文摘要
以前的工作表明,发展的理解,在原位粒子粒子的力量是一个先决条件,涉及到单粒子微观相互作用的中尺度散装行为。在Johnson-Matthey(项目工业赞助商)的业务运营中,与流变学、表面涂层和研磨等现象相关的批量加工问题无处不在,解决方案通常通过向配方中添加额外组分或“工艺绷带”来实现。虽然这种方法有一些优点,但它对提高对基础微观相互作用的理解几乎没有帮助,导致公式越来越复杂,理解越来越少。在这方面,有必要建立一个基本的知识库,了解聚合物如何与颗粒相互作用,并研究这种相互作用对分散,流动行为和涂层性能等整体性能的影响。模型颗粒系统可以合成为特定的几何形状,形状和尺寸,这将有助于测量这种颗粒-颗粒相互作用。然后,这些模型系统可以与Johnson-Matthey相关系统相关,例如用于排放控制技术的沸石(立方体)和用于先进玻璃技术的研磨玻璃颗粒(球形),从而提供对所得浆料内的改进配方的见解。
英文摘要
Previous work has shown that developing an understanding of in situ particle-particle forces is a pre-requisite to relate mesoscale bulk behaviour to single particle microscopic interactions. Bulk processing issues relating to phenomena such as rheology, surface coating and milling are ubiquitous throughout business operations relating to Johnson-Matthey (the project industrial sponsor) and the solutions are often arrived at with the addition of extra components to the formulation or a "process bandage". While such an approach has some merit, it does little to improve the appreciation of the underpinning microscopic interactions, resulting in formulations of increasing complexity with ever diminishing understanding. In this regard there is a need to build a fundamental knowledge base understanding how polymers interact with particulates and study the impact of this interaction on bulk properties such as dispersion, flow behaviour and coating performance. Model particulate systems can be synthesized to specific geometries, shapes and sizes that will facilitate the measurement of such particle-particle interactions. These model systems can then be related to Johnson-Matthey relevant systems such as zeolites for Emission Control Technology (cubic), and milled glass particles for Advanced Glass Technology (spherical), in relation to offering insight for improved formulation within the resulting slurries.
