Multi Factorial Analysis of Foam Properties

Improved understanding of foam density, viscosity, and penetration time facilitates consistent foam to fabric application. An experiment applied four control variables (Laviron 118S-surfactant, Kelzan S-thickener, blow ratio, and rotor speed) at five levels (-2, -1, 0, 1, 2) to Mondomix generated foam. Multiple regression analysis revealed that blow ratio and rotor speed affected foam density and that surfactant, thickener, blow ratio, and rotor speed affected foam viscosity and penetration. The linear relationship of foam viscosity to all control variables suggested that blow ratio modification conferred economic benefits to foam generation.
