Comparison between the Effects of Anti-fogging Agent, Glucose Solution and Various Concentrations of Salt Solutions on Preventing Glass Fogging

Abstract

The fog which condenses on the glass often affects people's life and work. For example, fog may condense on medical instruments，blocking the user's vision and causing users be injured by the equipment.Therefore,it is necessary to conduct a study of preventing fogging on glass.Currently, one of the most common method to prevent fogging is to apply liquid coating on glass. This study aimed to evaluate the difference between different kinds and concentrations of solutions and salt solution on preventing glass fogging. The experiment was conducted measuring the fogging time of 5 different concentrations of salt water and sugar solution (0.5%, 1.0%, 3.0%, 5.0%, 10.0%), anti-fogging agent, and pure water. These preliminary results may suggest that the salt solution with a concentration of more than 5% showed better anti-fogging property than pure water and sugar solution.Although the effect of the salt solution is lower than the anti-fogging agent, salt solution could be considered to replace the anti-fogging agent in the large area defogging, because of its low cost.
