叠层法制备玻璃陶瓷微通道反应器的研究

Study on Laminated Preparation of Glass-ceramics Micro-channel Reactor

以60%(质量分数)的硼硅酸盐玻璃粉体与40%(质量分数)的Al2O3复合后获得的玻璃陶瓷粉体为固相,利用水性苯丙乳胶作为粘结剂得到了性能较好、结构均匀、高致密度、无毒环保的玻璃陶瓷流延片。通过室温直接叠层获得了微通道反应器原型器件。在860℃烧结后,微通道反应器原型器件的相对密度最大可达93.38%,体积密度达2.48g/cm3。所制备原型器件的T型通道在烧结后形状规则、无变形,说明利用水基流延叠层工艺制备微通道反应器是可行的。

Glass-ceramic powders were first fabricated by 40wt% alumina and 60wt% BeO3-SiO2 glass powders. Glass-ceramics green tape was obtained by aqueous tape casting processing with latex as binders. The green tapes have good mechanical properties, homogeneous microstructure, high density and smooth surface. Under room temperature, micro-channel reactor was laminated by green tape and then sintered at the range of 850-900℃. After sintered the body of micro-channel reactor, the largest relative density can reach 95.38%, the bulk density can reach 2.48g/cm^3 at 860℃. The shape of T type channel can hold well and no distortion, which proves the micro-channel reactor through aqueous tape casting, is feasible to fabricate.
