摘要

本研究旨在利用近红外光谱和化学计量学研究聚羧酸盐胶结物的反应动力学。为了实现医疗器械和药品的100%检验，需要开发非破坏性、非接触式的质量控制方法。一种有效的方法是化学计量学，它使用近红外光谱和化学计量学。制备一种聚羧酸骨水泥，用近红外光谱观察其在1 ~ 15 min内的光谱变化。用二维相关光谱法对所得光谱进行了评价。采用主成分分析法对水泥中羧酸盐的变化进行了分析，并绘制了随载荷和时间变化的计分图。结果表明，水泥的硬化机理可以描述为准一级反应。

Monitoring Dental Zinc Oxide Polyacrylate Cement Using Near-Infrared Spectroscopy

This study aims to investigate the reaction kinetics of polycarboxylate cements using NIR spectroscopy with chemometrics. To achieve 100% inspection of medical devices and drugs, it is desirable to develop non-destructive, non-contact quality control methods. One effective method for this is chemometrics, which uses near-infrared spectroscopy and chemometrics. A dental cement, polycarboxylate cement, was prepared, and the spectral changes from 1 min to 15 min were observed using NIR spectroscopy. The obtained spectra were evaluated by two-dimensional correlation spectroscopy. Carboxylate changes in the cement were analyzed using principal component analysis, and a score plot against loadings and time was shown. It was suggested that the hardening mechanism of cement can be plotted as a pseudo-first-order reaction.
