Herein, we present a study of the impact of the jar and ball medium on the performance in the mechanochemical amorphization of chitin. We measured the crystallinity index of chitin after milling it in a vibration mill in an apparatus made of copper, aluminum, brass, tungsten carbide, zirconia, stainless steel, polytetrafluoroethylene (PTFE), or poly(methyl methacrylate) (PMMA). These materials offer a range of Vickers hardness values and the impact of these parameters is discussed. The role of the size and mass of the balls is also studied in the case of stainless steel. This study also highlights one of the major challenges during milling, which is contamination of the studied samples.
在此，我们展示了一项关于 jar 和球磨介质对几丁质机械化学非晶化性能影响的研究。我们在由铜、铝、黄铜、碳化钨、氧化锆、不锈钢、聚四氟乙烯（PTFE）或聚甲基丙烯酸甲酯（PMMA）制成的装置中的振动磨中研磨几丁质后，测量了其结晶度指数。这些材料具有一系列维氏硬度值，并讨论了这些参数的影响。在不锈钢的情况下，还研究了球的尺寸和质量的作用。这项研究还突出了研磨过程中的一个主要挑战，即所研究样品的污染。
