Abstract
Microwave drying technology, as an efficient and energy-saving drying method, demonstrates unique advantages in the preparation of chemical materials. Conventional drying methods suffer from high energy consumption, low efficiency, and potential damage to material properties, whereas microwave drying achieves rapid and uniform heating through direct interaction between electromagnetic waves and materials, effectively overcoming these drawbacks. This study investigates the application effects and mechanisms of microwave drying technology in the preparation processes of various chemical materials. By integrating experimental research with theoretical analysis, multiple typical chemical materials were selected as ob jects to systematically examine the influence of factors such as microwave power, drying time, and material characteristics on drying performance. The results indicate that microwave drying significantly reduces drying cycles and energy consumption while better preserving the microstructure and physicochemical properties of materials. Notably, in the preparation of special materials like nanomaterials and polymer materials, microwave drying exhibits superior performance by effectively preventing agglomeration and enhancing material dispersibility. Furthermore, in-depth studies of the drying process led to the establishment of a kinetic model for microwave drying, revealing the heat and mass transfer rules within materials under microwave fields. This research not only provides new insights into optimizing chemical material preparation processes but also lays a theoretical foundation for the industrial application of microwave drying technology, possessing significant academic value and practical implications.
