多功能兼容的耐低温防除冰电加热膜的设计与优化OA

Electrothermal coatings/films have attracted extensive attention in the field of anti-icing due to their advantages of stable and reliable,rapid thermal response and high heat transfer efficiency.However,electrothermal coatings/films rarely focus on long-term service performance in low and cryogenic environments.This paper,committed to realizing the low temperature resistance of electrothermal films,and by analyzing the adhesion and flexibility at low temperatures,this paper developed and optimized a low-temperature anti-de-icing electrothermal film with a double substrate,which can maintain strong adhesion,high flexibility,and stable and rapid temperature rise even at-163℃.Through the dynamic anti-icing and the deep low temperature transition detection test,it is verified that the electrothermal film has stable and reliable anti-icing performance and uniform electric heating performance under low and deep low temperature environmental conditions,which is expected to solve the icing problems of aircraft and other equipment in high latitude and altitude areas and the transition sensing detection problem at deep low temperature.
