The influence of temperature on the properties of anti - ice materials

Abstract

The results of experimental research and practical application of anti-icing surface fully show that its performance is greatly affected by temperature. The anti-icing measures of anti-icing surface can be divided into three stages: before icing, during icing and after icing. In these three stages, the influence brought by temperature change is respectively reflected in: the adhesion of water droplets to the surface, the time it takes for ice nucleation, the adhesion of ice to the surface. Surface anti-ice technology has important application in aviation and aerospace field. The surface temperature of aircraft will change greatly when the aircraft is sailing at different altitudes and passing through different climatic environments. If ice accumulates in some parts of the aircraft, even if it is small, it may lead to a decrease in the climbing force of the aircraft and an increase in flight resistance, thus leading to the deterioration of aerodynamic performance such as the maneuverability and stability of the aircraft. Studying the influence of these temperature changes on the anti-icing performance of aircraft surface can avoid the air disaster caused by surface icing. Starting from these three stages, this paper analyzes the influence of temperature on material surface and the liquid itself successively in these three stages, so as to further explore the influence of temperature on ice suppression performance.
