Study on a novel technique of azeotropic dehydration process for drying methomyl oxime; 介绍了水在液化气中的存在形式和脱水方法的研究进展。
All samples were characterized by X-ray diffraction and transmission electron microscope to investigate the effects of azeotropic distillation drying methods on the morphology and particle size of nanoscale magnesia. 通过透射电子显微镜和X射线衍射仪的表征与分析,研究不同共沸蒸馏置换干燥法对纳米氧化镁粉体形貌、颗粒尺寸和团聚情况的影响;
Therefore, butoxy in n_butanol can be adsorbed chemically on the surfaces of the tourmaline particles in the process of azeotropic distillation, which can effectively prevent the formation of liquid_bridge between the particles of tourmaline and avoid the hard aggregation in the drying process. 正丁醇中的丁氧基在共沸蒸馏过程中在电气石颗粒表面可取代羟基,产生化学吸附,能有效防止液桥的产生,阻止干燥过程中超细粉末的硬团聚。
Preparation of Antimony-doped Tin Oxide Nano-powder with Low Agglomeration by Novel Azeotropic Drying of Iso-amyl Acetate 乙酸异戊酯共沸干燥法制备低团聚掺锑氧化锡纳米微粉
Preparation and Characterization of Indium Tin Oxide Nanocrystal powder by Azeotropic Drying with Iso-Amyl Acetate Method 共沸蒸馏干燥法制备氧化铟锡纳米粉体及其性能表征
The results show that when the direct drying method is used the size of nanometer particle prepared is more than 100 nm. While azeotropic distillation and supercritical drying methods are used, the powder prepared has good dispersity with the size of less than 10 nm. 通过比较,直接干燥法制备的纳米粒子粒径大于100nm,而采用共沸蒸馏和超临界干燥制得的粉体分散性好,可制备出粒径小于10nm的粉体。
