摘要

本研究调查了石英、莫来石、尖晶石和刚玉填料对硅玻璃悬浮基组合物的流变特性和挤出性的影响。结果表明，含有莫来石、尖晶石和刚玉的材料表现出扩张性流动行为，这阻碍了它们在 3D 打印中用作墨水。相反，含有石英填料的悬浮液则表现出非线性粘塑性流动。在含有石英填料的组合物中加入聚乙烯醇，可通过提高屈服应力和粘度来增强其在挤压过程中的形状保持因子。

Rheological Characteristics of Highly Concentrated Silica Glass Suspensions for 3D Printing of Refractories

The present study investigates the impact of quartz, mullite, spinel, and corundum fillers on the rheological properties and extrudability of silica glass suspension-based compositions. The results indicate that materials containing mullite, spinel, and corundum exhibit dilatant flow behavior, which impedes their use as inks in 3D printing. Conversely, suspensions containing quartz filler display a nonlinear viscoplastic flow. The addition of polyvinyl alcohol to compositions with quartz filler enhances their shape retention factor during extrusion by increasing their yield stress and viscosity.
