通过研究纤维素醚水溶液在不同温度下的粘性行为和纤维素醚在静态空气和氮气流中的热裂解及其裂解活化能计算,探讨了改性羧甲基羟丙基纤维素醚的热稳定性。结果表明:与羧甲基羟丙基纤维素醚相比较,改性羧甲基羟丙基纤维素醚的粘度热稳定性和裂解热稳定性都有一定程度的提高。
By studying the viscous behavior of cellulose ether aqueous solution at different temperatures and the thermal cracking and activation energy of cellulose ether in static air and nitrogen flow, the thermal stability of the modified carboxymethylhydroxypropyl cellulose ether Sex. The results showed that compared with carboxymethylhydroxypropyl cellulose ether, the viscosity thermal stability and thermal stability of the modified carboxymethyl hydroxypropyl cellulose ether all increased to a certain degree.
