Abstract
AbstractIn this study, the technology of micro‐segmented flow was applied for continuous synthesis safely and shape control accurately to lead trinitroresorcinate (LTNR) particles. Besides, a micro chemical reaction and crystallization system were built. Crystal shape control technology of LTNR and micro‐segmented flow technology were first combined using the system. Additionally, the effects of the flowing rate and chemical additives on LTNR micro‐particles preparation were researched for shape control. The LTNR micro‐particles were analyzed by XRD, DSC, laser scanning confocal microscope and laser particle size analyzer. The results shows that the LTNR particles size can be controlled from 20 to 400 μm by the flow rate and the concentration of hexadecyl trimethyl ammonium bromide (CTAB), while the shape of LTNR can be controlled by the concentration of glycerol and CTAB. Besides, there is a good linear relationship between the size and the activation energy. This illustrates that the LTNR particles with smaller size are more stable and have higher heat release. This study demonstrated the power of micro‐segmented flow for generation of LTNR micro‐particles with high quality and for tuning of particle properties.
