古代蚕丝的热分析动力学研究
Investigation of the thermal degradation and kinetics of ancient silk
摘要
Abstract
In this study:silk fabrics of the Southern Song Dynasty and the Warring States Period were selected as the investigated objects;modern silk was taken as reference.The microscopic structure of the samples was observed by scanning electron microscopy,and thermogravimetric analysis was performed based on the principle of thermal analysis kinetics.The kinetic parameters of silk were calculated by applying Flynn-Wall-Ozawa,Kissinger-Akahira-Sunose and Kissinger models,and the relevant thermodynamic parameters were obtained.In this study,the thermal analysis kinetic method was introduced into the study of degradation of silk cultural relics,and the differences of the kinetic and thermodynamic parameters between modern silk and ancient silk were investigated.The thermal stability,degradation state and chemical properties of silk cultural relics were determined by the characteristic scale of activation energy,activation enthalpy and activation Gibbs free energy.This study has reference value for revealing the degradation mechanism and evaluating the degree of degradation of silk cultural relics,and also provides theoretical guidance for predicting the duration life of silk cultural relics.关键词
