Study on physicochemical properties and simulation modification of crepe paper for power equipments
Crepe paper is an essential insulating material for transformers and high-voltage cables.Currently,all high-performance crepe paper is imported.In order to realize the localization of crepe paper for high-end power equipment and improve the long-term reliability of crepe paper,it is urgent to carry out research on the physicochemical properties and performance improvement technology of crepe paper.The physicochemical and macroscopic properties of crepe papers from different manufacturers were tested and analyzed in this paper,and the key physicochemical parameters that affect the performance of crepe papers were extracted.Three functional groups were introduced into the cellulose systems through grafting modification,the properties of the cellulose systems before and after grafting modification were analyzed using Materials Studio software,and the effects of different functional groups on the various properties of the cellulose systems were investigated.The results show that the benzene ring has the most obvious improvement on the thermal properties of the cellulose system,the methylene long chain can improve the insulating properties of the cellulose system,and the benzene ring can improve the mechanical properties of the cellulose system.
