Interpretation of Foam Performance of Aerosol Type Glass Cleaner in Terms of Dynamic Surface and Interfacial Tensions

摘要

Measurements of dynamic interfacial and surface tensions were conducted on the system consisting of a propellant (liquefied petroleum gas, LPG) and a surfactant solution as an aerosol glass cleaner and discussions were made of its foam performance such as homogeneous foam spray patterns on vertical glass plate with no dripping. The lower the dynamic interfacial tension between LPG and surfactant solution was, the higher was the stability of spray pattern without dripping, and the lower the dynamic surface tension at 100msec of surfactant solution was, the more homogenous was the pattern of foam spray.
