Prediction of Polymer Content Profile in Convective Dried Porous Slab Wetted with Polymer Solution

Abstract

A mathematical model was proposed that gave the polymer content profile in convective dried porous material wetted with polymer solution. The model equations were simple and practical. Convective drying experiments were performed by using a glass particle layer wetted with aqueous polyvinyl alcohol solution or styrene-butadiene rubber latex, and polymer content profiles in dried samples were measured. Agreement between the calculated and the measured results was satisfactory.
